NAMEXmContainer — The Container widget class .iX "XmContainer" .iX "container" "Container"
SYNOPSIS#include <Xm/Container.h>
DESCRIPTIONContainer manages child widgets that have the ContainerItem trait. These child widgets can be viewed in several different layout formats, selected using different selection types and techniques, and directly manipulated by the user. Three different formats or views are supported by the Container. They are specified via the XmNentryViewType resource: • XmLARGE_ICON • XmSMALL_ICON • XmANY_ICON Three different layout types are supported by the Container. They are specified by the XmNlayoutType resource: • XmSPATIAL • XmOUTLINE • XmDETAIL In the XmSPATIAL layout type, several other resources (XmNspatialStyle, XmNspatialIncludeModel, XmNspatialSnapModel) control the positioning of the items within the Container; an application programmer can specify these resources so that the Container strictly enforces the position of each item or so that the Container positions items according to constraint resources specified for each item. The user, however, can alter the position of an item in the XmSPATIAL layout type within the Container by direct manipulation; for example, by pressing BTransfer over the item and then dragging and releasing BTransfer over some location within the Container. In the XmOUTLINE layout type, the Container controls the positioning of the items. Items within the Container can have parent-child relationships between them. Each item's XmNentryParent resource can specify another item in the same Container as its parent; items with a non-NULL value for XmNentryParent can only be displayed in the XmOUTLINE layout type. In the XmOUTLINE layout type, items are positioned in a tree configuration with connecting lines drawn to illustrate the relationships. Items are positioned top to bottom in the order specified by XmNpositionIndex within their parent. Container positions a PushButton next to each item that has a parent relationship to other items. The PushButton contains a pixmap to illustrate whether the child items are shown or not; the user can activate the PushButton to toggle between showing or hiding the child items. Direct manipulation to alter the position of the item is not supported in the XmOUTLINE layout type. Note that the XmNtraversalOn resource of the PushButtons created by Container are set to False. The XmDETAIL layout type is the same as XmOUTLINE, except that each item can also display additional information as rows in columns with column headers specified in the XmNdetailColumnHeading resources. In each item row, the item's detail information (see the reference page on XmIconGadget for a description of the XmNentryDetail resource) is displayed. Items are positioned top to bottom in the order specified by XmNpositionIndex within the parent.
SelectionWhen a child widget of the container is selected, the container specifies that the item should display the appropriate visual information to the user via the ContainerItem trait. The application program is notified of selection changes through XmNselectionCallback. The container uses four selection policies: • Single • Browse • Multiple • Extended In Single Select and Browse Select modes, only one item can be selected at a time. Pressing BSelect on an item selects it and deselects any other selected item. Pressing BSelect over an empty space in the Container deselects all items. In Browse Select, dragging BSelect moves the selection as the pointer is moved. In Multiple Select and Extended Select modes, any number of items can be selected at the same time. In Multiple Select, pressing and dragging BSelect or BExtend to specify an item, range of items, or group of discontiguous items causes the selection states of those items to be toggled. In Extended Select, pressing and dragging BSelect to indicate an item, range of items, or group of discontiguous items selects those items and deselects all others. Pressing and dragging BExtend in Extended Select to indicate an item, range of items, or discontiguous group of items causes the selection states of those items to be toggled. Several techniques are available to indicate an item, range of items, or group of discontiguous items in the Multiple Select and Extended Select modes. In the XmSPATIAL and XmOUTLINE layout types, the XmNselectionTechnique resource specifies the techniques to be used to indicate items. The default specification of XmTOUCH_OVER allows both the Random-Swipe and Marquee techniques to be used when XmNlayoutStyle is XmSPATIAL. The default specification of XmTOUCH_OVER allows the Range-Swipe, Range-Click, and Marquee techniques to be used when XmNlayoutStyle is XmOUTLINE. Discontiguous groups of items can be selected using the Random-Swipe technique. In the Random-Swipe technique, pressing BSelect (or BExtend) over an item and dragging BSelect over other items selects all of those items. Only those items that pointer passed over are selected. In the Range-Swipe technique, the user presses BSelect (or BExtend) over the first item and releases BSelect over the last item; all items within the range between the first and last item are selected whether the pointer actually passed over them or not. In the Range-Click technique, the user presses and releases BSelect (or BExtend) over the first item and then presses and releases BExtend over the last item. In the Marquee technique, pressing BSelect (or BExtend) over a blank space within the Container indicates the starting point of a Marquee rectangle. Dragging BSelect draws a Marquee rectangle (rubberband line) between the starting point and current pointer. All items completely within the Marquee rectangle are selected. Specifying XmTOUCH_ONLY for XmNselectionTechnique enforces the Random-Swipe technique even when BSelect (or BExtend) is pressed over a blank space. Similarly, specifying XmMARQUEE enforces the Marquee technique even when BSelect (or BExtend) is pressed over an item; since the item over which the press occurs is only partially included in the Marquee rectangle, it is not selected. XmMARQUEE_EXTEND_START and XmMARQUEE_EXTEND_BOTH enforce the Marquee technique and also cause the rectangle to extend automatically around the first item indicated and, for XmMARQUEE_EXTEND_BOTH, the last item. In the XmDETAIL layout type, the Range-Swipe and Range-Click techniques are available to indicate a range of items for selection. Container uses the XmQTcontainerItem, XmQTscrollFrame, and XmQTspecifyRenderTable traits and holds the XmQTcontainer and XmQTtransfer traits.
Data Transfer BehaviorContainer supports dragging of selected items from the widget. Depending on the value of XmNprimaryOwnership, Container can also support primary selection. As a source of data, Container supports the following targets and associated conversions of data to these targets: locale If the locale target matches the widget's locale, the widget transfers the selected items in the encoding of the locale. The value for each item transferred, except the last, includes a trailing separator. Each item value is the XmNlabelString of the item. COMPOUND_TEXT The widget transfers the selected items as type COMPOUND_TEXT. The value for each item transferred, except the last, includes a trailing separator. Each item value is the XmNlabelString of the item. DELETE The widget deletes the selected items. PIXMAP The widget transfers a list of the pixmap IDs of the selected items as type DRAWABLE. STRING The widget transfers the selected items as type STRING. The value for each item transferred, except the last, includes a trailing separator. Each item value is the XmNlabelString of the item. TEXT If the selected items are fully convertible to the encoding of the locale, the widget transfers the selected items in the encoding of the locale. Otherwise, the widget transfers the selected items as type COMPOUND_TEXT. The value for each item transferred, except the last, includes a trailing separator. Each item value is the XmNlabelString of the item. _MOTIF_CLIPBOARD_TARGETS The widget transfers, as type ATOM, a list of the targets it supports for immediate transfer for the CLIPBOARD selection. These include _MOTIF_COMPOUND_STRING and PIXMAP. If the selected items are fully convertible to STRING, these also include STRING; otherwise, they also include COMPOUND_TEXT and UTF8_STRING. _MOTIF_COMPOUND_STRING The widget transfers the selected items as a compound string in Byte Stream format. The value for each item transferred, except the last, includes a trailing separator. Each item value is the XmNlabelString of the item. UTF8_STRING The widget transfers the selected items as type UTF8_STRING. The value for each item transferred, except the last, includes a trailing separator. Each item value is the XmNlabelString of the item. _MOTIF_DEFERRED_CLIPBOARD_TARGETS The widget transfers, as type ATOM, a list of the targets it supports for delayed transfer for the CLIPBOARD selection. This widget currently supplies no targets for _MOTIF_DEFERRED_CLIPBOARD_TARGETS. _MOTIF_DRAG_OFFSET The widget transfers a list of two 16-bit numbers, of type INTEGER, representing an x and y offset for an item being dragged. This offset is calculated so that, if the offset were added to the x and y coordinates at the drop site, and the dragged pixmap placed at that position, it would correspond to the position the user would expect the pixmap to placed at, based on the drag icon used at the drop site. _MOTIF_EXPORT_TARGETS The widget transfers, as type ATOM, a list of the targets to be used as the value of the DragContext's XmNexportTargets in a drag-and-drop transfer. These include _MOTIF_COMPOUND_STRING, PIXMAP, COMPOUND_TEXT, the encoding of the locale, STRING, TEXT, BACKGROUND, FOREGROUND, and UTF8_STRING. As a source of data, Container also supports the following standard Motif targets: BACKGROUND The widget transfers XmNbackground as type PIXEL. CLASS The widget finds the first shell in the widget hierarchy that has a WM_CLASS property and transfers the contents as text in the current locale. CLIENT_WINDOW The widget finds the first shell in the widget hierarchy and transfers its window as type WINDOW. COLORMAP The widget transfers XmNcolormap as type COLORMAP. FOREGROUND The widget transfers XmNforeground as type PIXEL. NAME The widget finds the first shell in the widget hierarchy that has a WM_NAME property and transfers the contents as text in the current locale. TARGETS The widget transfers, as type ATOM, a list of the targets it supports. These include the standard targets in this list. These also include _MOTIF_COMPOUND_STRING, PIXMAP, COMPOUND_TEXT, the encoding of the locale, STRING, TEXT, and UTF8_STRING. TIMESTAMP The widget transfers the timestamp used to acquire the selection as type INTEGER. _MOTIF_RENDER_TABLE The widget transfers XmNrenderTable if it exists, or else the default text render table, as type STRING. _MOTIF_ENCODING_REGISTRY The widget transfers its encoding registry as type STRING. The value is a list of NULL separated items in the form of tag encoding pairs. This target symbolizes the transfer target for the Motif Segment Encoding Registry. Widgets and applications can use this Registry to register text encoding formats for specified render table tags. Applications access this Registry by calling XmRegisterSegmentEncoding and XmMapSegmentEncoding. As a destination for data, Container supports only the dropping of items being dragged from the same widget. Subclasses and the XmNdestinationCallback procedures are responsible for any other data transfers to the widget.
ClassesContainer inherits behavior, resources, and traits from the Core, Composite, Constraint, and XmManager classes. The class pointer is xmContainerWidgetClass. The class name is XmContainer.
New ResourcesThe following table defines a set of widget resources used by the programmer to specify data. The programmer can also set the resource values for the inherited classes to set attributes for this widget. To reference a resource by name or by class in a .Xdefaults file, remove the XmN or XmC prefix and use the remaining letters. To specify one of the defined values for a resource in a .Xdefaults file, remove the Xm prefix and use the remaining letters (in either lowercase or uppercase, but include any underscores between words). The codes in the access column indicate whether the given resource can be set at creation time (C), set by using XtSetValues (S), retrieved by using XtGetValues (G), or is not applicable (N/A).

It can have one of the following values: XmAUTO_SELECT Makes selection callbacks automatically when each item is selected or toggled. This may also be the value TRUE. XmNO_AUTO_SELECT Delays selection callbacks until the user has finished selection actions. This may also be the value FALSE. XmNcollapsedStatePixmap Specifies the pixmap to display on a PushButton next to a Container item with child items, when XmNoutlineButtonPolicy is XmOUTLINE_BUTTON_PRESENT. XmNcollapsedStatePixmap indicates that the child items are not displayed. If set to XmUNSPECIFIED_PIXMAP, a default pixmap showing an arrow pointing up is used. XmNconvertCallback Specifies a list of callbacks called when the Container is asked to convert a selection. The type of the structure whose address is passed to these callbacks is XmConvertCallbackStruct. The reason is XmCR_OK. XmNdefaultActionCallback Specifies a list of callbacks to call when the user double-clicks an item or presses <Enter> or <Return> over an item. The callback structure is XmContainerSelectCallbackStruct. The reason is XmCR_DEFAULT_ACTION. XmNdestinationCallback Specifies a list of callbacks called when the Container is the destination of a transfer operation. The type of the structure whose address is passed to these callbacks is XmDestinationCallbackStruct. The reason is XmCR_OK. XmNdetailColumnHeading Specifies a table of XmStrings to display as the headings to columns. If NULL, or if XmNlayoutType is not XmDETAIL, no heading is displayed. XmNdetailColumnHeadingCount Specifies a count of XmStrings in the table specified for XmNdetailColumnHeading. XmNdetailOrder Specifies an array of Cardinals that indicate which column detail information, and in which order, each Container child will display its detail information. This resource is ignored if XmNlayoutType is not XmDETAIL. If NULL, the the default behavior is determined by XmNdetailOrderCount. XmNdetailOrderCount Specifies a count of Cardinals in the array specified for XmNdetailOrder. If XmNdetailOrder is NULL and XmNdetailOrderCount is not 0, then each Container child displays its detail information in order from column 1 to the XmNdetailOrderCount column number. If XmNdetailOrderCount is 0, then a default is calculated from the detail order count information of each item accessed via the ContainerItem trait. XmNdetailTabList Indicates an XmTabList specifying the start of each column in the XmDETAIL layout. If this resource is set to NULL, then Container calculates an XmTabList. This resource is ignored if XmNlayoutType is not XmDETAIL. XmNentryViewType Specifies the view type for all Container children. The view type is specified for each item via the ContainerItem trait. It can have one of the following values: XmANY_ICON No specification is made for Container children. Children use their own default specifications. XmLARGE_ICON The view type for all children is XmLARGE_ICON. XmSMALL_ICON The view type for all children is XmSMALL_ICON. XmNexpandedStatePixmap Specifies the pixmap to display on a PushButton next to a Container item with child items, when XmNoutlineButtonPolicy is XmOUTLINE_BUTTON_PRESENT. XmNexpandedStatePixmap indicates that the child items are displayed. If set to XmUNSPECIFIED_PIXMAP, a default pixmap showing an arrow pointing down is used. XmNfontList Specifies the fontlist associated with XmContainer. The fontlist is an obsolete construct and has been superseded by the render table. It is included for compatibility with earlier versions of Motif, and for applications that do not easily support render tables. The default fontlist is derived from the default render table; and if both a fontlist and a render table are specified, the render table takes precedence. XmNlargeCellHeight Specifies the height of a cell for XmGRID or XmCELLS spatial style when XmNentryViewType is XmLARGE_ICON or XmANY_ICON. XmNlargeCellWidth Specifies the width of a cell for XmGRID or XmCELLS spatial style when XmNentryViewType is XmLARGE_ICON or XmANY_ICON. XmNlayoutType Specifies the policy for laying out child widgets within the Container. It can have one of the following values: XmDETAIL Displays items in the same manner as when the resource is XmOUTLINE, except that each item displays detail information next to it. XmOUTLINE Displays items in a tree configuration, in XmNpositionIndex within XmNentryParent order, with connecting lines drawn to show their parent-child relationships. XmSPATIAL Displays items according to XmNspatialStyle. Items with XmNentryParent values are not displayed. XmNmarginHeight Specifies the margin spacing at the top and bottom of the Container. XmNmarginWidth Specifies the margin spacing at the left and right sides of the Container. XmNoutlineButtonPolicy Specifies whether or not to display buttons for users to expand and collapse the display of items. It can have one of the following values: XmOUTLINE_BUTTON_ABSENT Do not display the outline buttons. XmOUTLINE_BUTTON_PRESENT Display the outline buttons. XmNoutlineChangedCallback Specifies a list of callbacks to call when an item's XmNoutlineState is changed. The callback structure is XmContainerOutlineCallbackStruct. The reason is XmCR_COLLAPSED or XmCR_EXPANDED, depending on the new value of XmNoutlineState. XmNoutlineColumnWidth Specifies the width of the first column displayed when XmNlayoutType is XmDETAIL. Specifies the preferred width of the Container (without the margins) when XmNlayoutType is XmOUTLINE. If not specified, Container will determine a default value equal to the widest space necessary to display an item's pixmap and XmNoutlineIndentation. XmNoutlineIndentation Specifies the distance to indent for the display of child items when XmNlayoutType is XmOUTLINE or XmDETAIL. XmNoutlineLineStyle Specifies whether to draw lines between items with parent-child relationships when XmNlayoutType is XmOUTLINE or XmDETAIL. It can have one of the following values: XmNO_LINE Draws no line. XmSINGLE Draws a line one pixel wide. XmNprimaryOwnership Specifies whether Container takes ownership of the primary selection when a selection is made inside it. This resource can take the following values: XmOWN_NEVER Never takes ownership. XmOWN_ALWAYS Always takes ownership. XmOWN_MULTIPLE Only takes ownership if more than one element has been selected. XmOWN_POSSIBLE_MULTIPLE Only takes ownership if more than one element can be selected at a time. XmNrenderTable Specifies the XmRenderTable that is inherited by all children of the Container. The default is implementation dependent. If both a render table and a fontlist are specified, the render table will take precedence. XmNselectColor Specifies a Pixel that can be accessed by children of the Container and used to indicate that the child is in a selected state. In addition to a Pixel value, the following symbolic values can be specified: XmDEFAULT_SELECT_COLOR Specifies a color between the background and the bottom shadow color. XmREVERSED_GROUND_COLORS Forces the select color to the foreground color and causes the default color of any text rendered over the select color to be the background color. HIGHLIGHT_COLOR Forces the fill color to use the highlight color. XmNselectedObjectCount Specifies the number of widgets in the selected items list. The value must be the number of items in XmNselectedObjects. XmNselectedObjects An array of widgets that represents the Container items that are currently selected, either by the user or by the application. If the application sets XmNselectedObjects to an array of widgets, those array elements that are valid Container items are selected. XmNselectionCallback Specifies a list of callbacks to call when an item is selected. The callback structure is XmContainerSelectCallbackStruct. The reason is XmCR_SINGLE_SELECT, XmCR_BROWSE_SELECT, XmCR_MULTIPLE_SELECT, or XmCR_EXTENDED_MULTIPLE, depending on XmNselectionPolicy. XmNselectionPolicy Defines the interpretation of the selection action. This can be one of the following values: XmSINGLE_SELECT Allows only single selections. XmBROWSE_SELECT Allows "drag and browse" selections. XmMULTIPLE_SELECT Allows multiple selections. XmEXTENDED_SELECT Allows extended selections. XmNselectionTechnique Specifies the selection technique to use when the Container displays items in a 2-dimensional layout (XmNentryViewType is XmLARGE_ICON or XmSMALL_ICON). In the XmDETAIL layout, the XmNselectionTechnique resource is treated as XmTOUCH_ONLY. In either case, it can have one of the following values: XmMARQUEE Uses the Marquee technique only. XmMARQUEE_EXTEND_START Uses the Marquee technique only and extends the Marquee rectangle around any item under the Marquee start point. XmMARQUEE_EXTEND_BOTH Uses the Marquee technique only and extends the Marquee rectangle around any items under the Marquee start and end points. XmTOUCH_ONLY Uses the Random-Swipe technique only if XmNlayoutType is XmSPATIAL. Otherwise, uses the Range-Swipe and Range-Click techniques. XmTOUCH_OVER If the selection action begins over an item and XmNlayoutType is XmSPATIAL, uses the Random-Swipe technique. If the selection action begins over an item and XmNlayoutType is XmOUTLINE or XmDETAIL, uses the Range-Swipe and Range-Click techniques. Uses the Marquee technique if the select action begins over an unoccupied area in the Container. XmNsmallCellHeight Specifies the height of a cell for XmGRID or XmCELLS spatial style when XmNentryViewType is XmSMALL_ICON. XmNsmallCellWidth Specifies the width of a cell for XmGRID or XmCELLS spatial style when XmNentryViewType is XmSMALL_ICON. XmNspatialIncludeModel Specifies the layout of an item when the item is managed in the Container when XmNlayoutType is XmSPATIAL and XmNspatialStyle is XmGRID or XmCELLS. It can have one of the following values: XmAPPEND Places the item after the last occupied cell according to XmNlayoutDirection. XmCLOSEST Places the item in the free cell closest to the position specified by XmNx and XmNy. XmFIRST_FIT Places the item in the first free cell according to XmNlayoutDirection. XmNspatialResizeModel Specifies how Container will attempt to grow its dimensions when XmNlayoutType is XmSPATIAL and XmNspatialStyle is XmGRID or XmCELLS and there are not enough cells to contain a new Container item. It can have one of the following values: XmGROW_BALANCED Container will request both width and height growth from its parent. XmGROW_MAJOR Container will request growth in its major dimension from its parent. Container's major dimension is width when the precedence of XmNlayoutDirection is horizontal, and height when vertical. XmGROW_MINOR Container will request growth in its minor dimension from its parent. Container's minor dimension is height when the precedence of XmNlayoutDirection is horizontal, and width when vertical. XmNspatialSnapModel Specifies how Container will position an item within the cell layout when XmNlayoutType is XmSPATIAL and XmNspatialStyle is XmGRID or XmCELLS. It can have one of the following values: XmCENTER Center the items as follows, depending on the value of XmNentryViewType: XmLARGE_ICON The child is centered in the cell horizontally and baseline-aligned vertically. XmSMALL_ICON The child is centered in the cell vertically on its baseline and aligned with the left or right of the cell horizontally, depending on the value of XmNlayoutDirection. XmSNAP_TO_GRID Position the item at the upper-left or upper-right corner of the cell(s), depending on the value of XmNlayoutDirection. XmNONE Position the item according to the position specified by XmNx and XmNy. If the position is not within the coordinates of the cell(s), then position the item at the upper-left or upper-right corner of the cell(s), depending on the value of XmNlayoutDirection. XmNspatialStyle Specifies the layout of Container items when XmNlayoutType is XmSPATIAL. It can have one of the following values: XmCELLS Lays out items within a grid of same-size cells. Each item occupies as many cells as required to contain the item dimensions. XmGRID Lays out items within a grid of same-size cells. Each item occupies only one cell. Items that are larger than the cell size may overlap other items. XmNONE Lays out items according to XmNx and XmNy. XmContainer Constraint Resource Set NameClassTypeDefaultAccess XmNentryParentXmCWidgetWidgetNULLCSG XmNoutlineStateXmCOutlineStateunsigned charXmCOLLAPSEDCSG XmNpositionIndexXmCPositionIndexintdynamicCSG XmNentryParent Specifies the widget that is this item's logical parent. A value of NULL indicates that this is a root-level item. Parent-child information is displayed only when the XmNlayoutPolicy is XmOUTLINE or XmDETAIL. XmNoutlineState Specifies whether to display child items when XmNlayoutPolicy is XmOUTLINE or XmDETAIL. It can have one of the following values: XmCOLLAPSED Does not display child items. XmEXPANDED Displays child items. XmNpositionIndex Specifies the order of items in the Container for display. When XmNlayoutType is XmOUTLINE or XmDETAIL, items are displayed in XmNpositionIndex order within XmNentryParent. Items that have an XmNentryParent resource are ignored when XmNlayoutType is XmSPATIAL. If XmNpositionIndex is not specified, it defaults to the XmNpositionIndex value plus 1 of the item with the highest XmNpositionIndex that has the same XmNentryParent if such an item exists; otherwise, it defaults to 0.

Callback InformationA pointer to the following structure is passed to callbacks for XmNoutlineChangedCallback. typedef struct
{
int reason;
XEvent * event;
Widget item;
unsigned char new_outline_state;
} XmContainerOutlineCallbackStruct;reason Specifies the reason for the callback. event Points to the XEvent that triggered the callback. It can be NULL. item Specifies the container item affected by the event. new_outline_state Specifies the next XmNoutlineState for item. The user can change this value in the callback. A pointer to the following structure is passed to callbacks for XmNdefaultActionCallback and XmNselectionCallback. typedef struct
{
int reason;
XEvent * event;
WidgetList selected_items;
int selected_item_count;
unsigned char auto_selection_type;
} XmContainerSelectCallbackStruct;reason Specifies the reason for the callback. It corresponds to the XmNselectionPolicy at the time the selection was made, or indicates that the default action should be taken. event Points to the XEvent that triggered the callback. It can be NULL. selected_items Specifies a list of items selected at the time of the event that caused the callback. The selected_items field points to a temporary storage space that is reused after the callback is finished. Therefore, if an application needs to save the selected list, it should copy the list into its own data space. selected_item_count Specifies the number of items in the selected_items list. This number must be positive or 0 (zero). auto_selection_type Indicates the cause of the selection when XmNautomaticSelection is XmAUTO_SELECT. Valid values are the following: XmAUTO_UNSET Returned when XmNautomaticSelection is XmNO_AUTO_SELECT. XmAUTO_BEGIN Indicates the beginning of automatic selection. XmAUTO_MOTION Indicates that there is a button drag selection. XmAUTO_CANCEL Indicates that the new selection is canceled. XmAUTO_NO_CHANGE Indicates that the currently selected item matches the initial item. XmAUTO_CHANGE Indicates that the currently selected item does not match the initial item. A pointer to the following structure is passed to the XmNconvertCallback procedures: typedef struct
{
int reason;
XEvent *event;
Atom selection;
Atom target;
XtPointer source_data;
XtPointer location_data;
int flags;
XtPointer parm;
int parm_format;
unsigned long parm_length;
int status;
XtPointer value;
Atom type;
int format;
unsigned long length;
} XmConvertCallbackStruct;reason Indicates why the callback was invoked. event Points to the XEvent that triggered the callback. It can be NULL. selection Indicates the selection for which conversion is being requested. Possible values are CLIPBOARD, PRIMARY, SECONDARY, and _MOTIF_DROP. target Indicates the conversion target. source_data Contains information about the selection source. When the selection is _MOTIF_DROP, source_data is the DragContext. Otherwise, it is NULL. location_data Contains information about the location of data to be converted. If the value is NULL, the data to be transferred consists of the widget's current selection. Otherwise, it is the widget ID of the item being transferred, or the widget ID of the Container if all items are being transferred. flags Indicates the status of the conversion. Following are the possible values: XmCONVERTING_NONE This flag is currently unused. XmCONVERTING_PARTIAL The target widget was able to be converted, but some data was lost. XmCONVERTING_SAME The conversion target is the source of the data to be transferred. XmCONVERTING_TRANSACT This flag is currently unused. parm Contains parameter data for this target. If no parameter data exists, the value is NULL. When selection is CLIPBOARD and target is _MOTIF_CLIPBOARD_TARGETS or _MOTIF_DEFERRED_CLIPBOARD_TARGETS, the value is the requested operation (XmCOPY, XmMOVE, or XmLINK). parm_format Specifies whether the data in parm should be viewed as a list of char, short, or long quantities. Possible values are 0 (when parm is NULL), 8 (when the data in parm should be viewed as a list of chars), 16 (when the data in parm should be viewed as a list of shorts), or 32 (when the data in parm should be viewed as a list of longs). Note that parm_format symbolizes a data type, not the number of bits in each list element. For example, on some machines, a parm_format of 32 means that the data in parm should be viewed as a list of 64-bit quantities, not 32-bit quantities. parm_length Specifies the number of elements of data in parm, where each element has the size specified by parm_format. When parm is NULL, the value is 0. status An IN/OUT member that specifies the status of the conversion. The initial value is XmCONVERT_DEFAULT. The callback procedure can set this member to one of the following values: XmCONVERT_DEFAULT The widget class conversion procedure, if any, is called after the callback procedures return. If the widget class conversion procedure produces any data, it overwrites the data provided by the callback procedures in the value member. XmCONVERT_MERGE The widget class conversion procedure, if any, is called after the callback procedures return. If the widget class conversion procedure produces any data, it appends its data to the data provided by the callback procedures in the value member. This value is intended for use with targets that result in lists of data, such as TARGETS. XmCONVERT_DONE The callback procedure has successfully finished the conversion. The widget class conversion procedure, if any, is not called after the callback procedures return. XmCONVERT_REFUSE The callback procedure has terminated the conversion process without completing the requested conversion. The widget class conversion procedure, if any, is not called after the callback procedures return. value An IN/OUT parameter that contains any data that the callback procedure produces as a result of the conversion. The initial value is NULL. If the callback procedure sets this member, it must ensure that the type, format, and length members correspond to the data in value. The callback procedure is responsible for allocating, but not for freeing, memory when it sets this member. type An IN/OUT parameter that indicates the type of the data in the value member. The initial value is INTEGER. format An IN/OUT parameter that specifies whether the data in value should be viewed as a list of char, short, or long quantities. The initial value is 8. The callback procedure can set this member to 8 (for a list of char), 16 (for a list of short), or 32 (for a list of long). length An IN/OUT member that specifies the number of elements of data in value, where each element has the size symbolized by format. The initial value is 0 (zero). A pointer to the following callback structure is passed to the XmNdestinationCallback procedures: typedef struct
{
int reason;
XEvent *event;
Atom selection;
XtEnum operation;
int flags;
XtPointer transfer_id;
XtPointer destination_data;
XtPointer location_data;
Time time;
} XmDestinationCallbackStruct;reason Indicates why the callback was invoked. event Points to the XEvent that triggered the callback. It can be NULL. selection Indicates the selection for which data transfer is being requested. Possible values are CLIPBOARD, PRIMARY, SECONDARY, and _MOTIF_DROP. operation Indicates the type of transfer operation requested. • When the selection is PRIMARY, possible values are XmMOVE, XmCOPY, and XmLINK. • When the selection is SECONDARY or CLIPBOARD, possible values are XmCOPY and XmLINK. • When the selection is _MOTIF_DROP, possible values are XmMOVE, XmCOPY, XmLINK, and XmOTHER. A value of XmOTHER means that the callback procedure must get further information from the XmDropProcCallbackStruct in the destination_data member. flags Indicates whether or not the destination widget is also the source of the data to be transferred. Following are the possible values: XmCONVERTING_NONE The destination widget is not the source of the data to be transferred. XmCONVERTING_SAME The destination widget is the source of the data to be transferred. transfer_id Serves as a unique ID to identify the transfer transaction. destination_data Contains information about the destination. When the selection is _MOTIF_DROP, the callback procedures are called by the drop site's XmNdropProc, and destination_data is a pointer to the XmDropProcCallbackStruct passed to the XmNdropProc procedure. When the selection is SECONDARY, destination_data is an Atom representing a target recommmended by the selection owner for use in converting the selection. Otherwise, destination_data is NULL. location_data Contains information about the location where data is to be transferred. The value is always NULL when the selection is SECONDARY or CLIPBOARD. If the value is NULL, the data is to be inserted at the widget's cursor position. Otherwise, the value is a pointer to an XPoint structure containing the x and y coordinates at the location where the data is to be transferred. Once XmTransferDone procedures start to be called, location_data will no longer be stable. time Indicates the time when the transfer operation began.
TranslationsThe XmContainer translations are listed below. The following key names are listed in the X standard key event translation table syntax. This format is the one used by Motif to specify the widget actions corresponding to a given key. A brief overview of the format is provided under VirtualBindings(3).

This option allows the actions for selection and transfer to be integrated on <Btn1>, and the actions for extending the selection can be bound to <Btn2>. The actions for <Btn1> that are defined in the preceding list still apply when the <Btn1> event occurs over text that is not selected. The following actions apply when the <Btn1> event occurs over text that is selected: ~c ~s ~m ~a <Btn1Down>: ContainerHandleBtn1Down(ContainerBeginSelect,Copy) c ~s ~m ~a <Btn1Down>: ContainerHandleBtn1Down(ContainerBeginToggle,Copy) c s ~m ~a <Btn1Down>: ContainerHandleBtn1Down(ContainerNoop,Link) ~c s ~m ~a <Btn1Down>: ContainerHandleBtn1Down(ContainerBeginExtend,Move) <Btn1Motion>: ContainerHandleBtn1Motion(ContainerButtonMotion) ~c ~s ~m ~a <Btn1Up>: ContainerHandleBtn1Up(ContainerEndSelect) c ~s ~m ~a <Btn1Up>: ContainerHandleBtn1Up(ContainerEndToggle) ~c s ~m ~a <Btn1Up>: ContainerHandleBtn1Up(ContainerEndExtend) c s ~m ~a <Btn1Down>: ContainerHandleBtn1Down(ContainerBeginExtend) c s ~m ~a <Btn1Up>: ContainerHandleBtn1Up(ContainerEndExtend) When Display's XmNenableBtn1Transfer resource has a value of XmBUTTON2_ADJUST, the following actions apply: ~c ~s ~m ~a <Btn2Down>: ContainerHandleBtn2Down(ContainerStartTransfer,Copy) c s ~m ~a <Btn2Down>: ContainerHandleBtn2Down(ContainerStartTransfer,Link) ~c s ~m ~a <Btn2Down>: ContainerHandleBtn2Down(ContainerStartTransfer,Move) <Btn2Motion>: ContainerHandleBtn2Motion(ContainerButtonMotion) ~m ~a <Btn2Up>: ContainerHandleBtn2Up(ContainerEndTransfer)
Action RoutinesThe Container action routines are described below. The current selections are always shown with the background color specified by the XmNselectColor resource. ContainerActivate(): This action calls XmNdefaultActionCallback with reason XmCR_DEFAULT_ACTION. ContainerBeginExtend(): Simply returns if XmNselectionPolicy is XmSINGLE_SELECT or XmBROWSE_SELECT. Simply returns if XmNlayoutType is XmSPATIAL. Otherwise, this action sets the selection state of all items between the anchor item and the item under the pointer to the selection state of the anchor item. The location cursor is moved to the item under the pointer. If XmNautomaticSelection is XmAUTO_SELECT, the XmNselectionCallback(s) is called with either XmCR_MULTIPLE_SELECT or XmCR_EXTENDED_SELECT as the reason depending on XmNselectionPolicy, and with auto_selection_type XmAUTO_CHANGE. ContainerBeginSelect(): If this is a second ContainerBeginSelect() action that has occurred within the time specified by the display's multiclick time, this action calls XmNdefaultActionCallback with reason XmCR_DEFAULT_ACTION and returns. Otherwise, processing depends on the value of XmNselectionPolicy as follows: XmSINGLE_SELECT This action deselects all items and toggles the item (if any) under the pointer. XmBROWSE_SELECT This action deselects all items and toggles the item (if any) under the pointer. This item is now the anchor item for further selection. If XmNautomaticSelection is XmAUTO_SELECT and a change in any item's selection state is made, the XmNselectionCallback(s) is called with reason XmCR_BROWSE_SELECT and auto_selection_type XmAUTO_BEGIN. XmMULTIPLE_SELECT If the pointer is over an item and XmNselectionTechnique is not XmMARQUEE, this action toggles the selection state of that item. The item becomes the anchor item for further selection. If XmNselectionTechnique is XmMARQUEE, XmMARQUEE_EXTEND_START, or XmMARQUEE_EXTEND_BOTH, this action sets the start point for the Marquee rectangle. If XmNselectionTechnique is XmMARQUEE_EXTEND_START or XmMARQUEE_EXTEND_BOTH and the pointer is over an item, this action draws the Marquee rectangle around the item. If XmNautomaticSelection is XmAUTO_SELECT, the XmNselectionCallback(s) is called with reason XmCR_MULTIPLE_SELECT and auto_selection_type XmAUTO_BEGIN. XmEXTENDED_SELECT All items are first deselected. Processing is then identical to the case where XmNselectionPolicy is XmMULTIPLE_SELECT, except that XmCR_EXTENDED_SELECT is the callback reason given if XmNselectionCallback is called. ContainerBeginToggle(): Simply returns if XmNselectionPolicy is XmSINGLE_SELECT or XmBROWSE_SELECT. Otherwise, if the pointer is over an item and XmNselectionTechnique is not XmMARQUEE, this action toggles the selection state of that item. The item becomes the anchor item for further selection. If XmNselectionTechnique is XmMARQUEE, XmMARQUEE_EXTEND_START, or XmMARQUEE_EXTEND_BOTH this action sets the start point for the Marquee rectangle. If XmNselectionTechnique is XmMARQUEE_EXTEND_START or XmMARQUEE_EXTEND_BOTH and the pointer is over an item, this action draws the Marquee rectangle around the item. If XmNautomaticSelection is XmAUTO_SELECT, the XmNselectionCallback(s) is called with either XmCR_MULTIPLE_SELECT or XmCR_EXTENDED_SELECT as the reason, depending on XmNselectionPolicy, and with auto_selection_type XmAUTO_BEGIN. ContainerButtonMotion(): Processing depends on the value of XmNselectionPolicy, as follows: XmSINGLE_SELECT This action simply returns to the caller. XmBROWSE_SELECT Simply returns if this action follows a ContainerBeginExtend() action or ContainerBeginToggle() action. If the pointer is no longer over the current anchor item, this action toggles the current anchor item and then toggles the item under the pointer (if any) and makes it the new anchor item for further processing. If XmNautomaticSelection is XmAUTO_SELECT and a change in any item's selection state is made, the XmNselectionCallback(s) is called with reason XmCR_BROWSE_SELECT and auto_selection_type XmAUTO_MOTION. XmMULTIPLE_SELECT If a previous action has set a Marquee rectangle start point, this action draws the Marquee rectangle between the current pointer position and the Marquee start point. If the XmNselectionTechnique is XmMARQUEE_EXTEND_BOTH and the pointer is over an item, the end point of the Marquee rectangle is extended to include the item. The selection states of all items within the Marquee rectangle are toggled to match the state of the anchor item. If no Marquee rectangle start point is set and the pointer is over an item, processing depends on the XmNlayoutType resource. The anchor item from the previous action is used. If XmNlayoutType is XmSPATIAL, the selection state of the item under the pointer is toggled to match the selection state of the anchor item. If XmNlayoutType is XmOUTLINE or XmDETAIL, the selection state of all items between the anchor item and the item under the pointer are toggled to match the selection state of the anchor item. If XmNautomaticSelection is XmAUTO_SELECT and a change in any item's selection state is made, the XmNselectionCallback(s) is called with reason XmCR_MULTIPLE_SELECT and auto_selection_type XmAUTO_MOTION. XmEXTENDED_SELECT Processing is identical to the case where XmNselectionPolicy is XmMULTIPLE_SELECT, except that XmCR_EXTENDED_SELECT is the callback reason given if XmNselectionCallback is called. ContainerCancel(): If a selection is in progress, this action restores selection states of all items to their state before the selection began. If XmNautomaticSelection is True and a change in any item's selection state is made, the XmNselectionCallback is called with reason XmCR_BROWSE_SELECT, XmMULTIPLE_SELECT, or XmCR_EXTENDED_SELECT depending on the XmNselectionPolicy resource and auto_selection_type XmAUTO_CANCEL. ContainerDeselectAll(): This action deselects all items and calls XmNselectionCallback with reason depending on XmNselectionPolicy. ContainerEndExtend(): Simply returns if XmNselectionPolicy is XmSINGLE_SELECT or XmBROWSE_SELECT. Simply returns if XmNlayoutType is XmSPATIAL. Otherwise, if XmNautomaticSelection is XmNO_AUTO_SELECT, XmNselectionCallback(s) is called with either XmCR_MULTIPLE_SELECT or XmCR_EXTENDED_SELECT as the reason depending on XmNselectionPolicy. If XmNautomaticSelection is XmAUTO_SELECT and no change is made in any item's selection state by this action, XmNselectionCallback(s) is called with either XmCR_MULTIPLE_SELECT or XmCR_EXTENDED_SELECT as the reason depending on XmNselectionPolicy and auto_selection_type XmAUTO_CHANGE. If XmNautomaticSelection is XmAUTO_SELECT and this action makes no change in any item's selection state, XmNselectionCallback(s) is called with either XmCR_MULTIPLE_SELECT or XmCR_EXTENDED_SELECT as the reason depending on XmNselectionPolicy and auto_selection_type XmAUTO_NO_CHANGE. ContainerEndSelect(): Processing depends on the value of XmNselectionPolicy, as follows: XmSINGLE_SELECT This action calls XmNselectionCallback with reason XmCR_SINGLE_SELECT. XmBROWSE_SELECT If the pointer is no longer over the current anchor item, this action toggles the current anchor item and then toggles the item under the pointer (if any). If XmNautomaticSelection is XmNO_AUTO_SELECT, the XmNselectionCallback(s) is called with reason XmCR_BROWSE_SELECT. If XmNautomaticSelection is XmAUTO_SELECT and a change in any item's selection state is made, XmNselectionCallback(s) is called with reason XmCR_BROWSE_SELECT and auto_selection_type XmAUTO_CHANGE. If XmNautomaticSelection is XmAUTO_SELECT and no change is made in any item's selection state by this action, XmNselectionCallback(s) is called with reason XmCR_BROWSE_SELECT and auto_selection_type XmAUTO_NO_CHANGE. XmMULTIPLE_SELECT This action first performs the same processing as the ContainerButtonMotion() action, except that XmNselectionCallback is not called. If XmNautomaticSelection is XmNO_AUTO_SELECT, the XmNselectionCallback(s) is called with reason XmCR_MULTIPLE_SELECT. If XmNautomaticSelection is XmAUTO_SELECT and a change in any item's selection state is made, the XmNselectionCallback(s) is called with reason XmCR_MULTIPLE_SELECT and auto_selection_type XmAUTO_CHANGE. If XmNautomaticSelection is XmAUTO_SELECT and this action makes no change in any item's selection state, XmNselectionCallback(s) is called with reason XmCR_MULTIPLE_SELECT and auto_selection_type XmAUTO_NO_CHANGE. XmEXTENDED_SELECT This action first performs the same processing as the ContainerButtonMotion() action, except that XmNselectionCallback is not called. If XmNautomaticSelection is XmNO_AUTO_SELECT, the XmNselectionCallback(s) is called with reason XmCR_EXTENDED_SELECT. If XmNautomaticSelection is XmAUTO_SELECT and a change in any item's selection state is made, XmNselectionCallback(s) is called with reason XmCR_EXTENDED_SELECT and auto_selection_type XmAUTO_CHANGE. If XmNautomaticSelection is XmAUTO_SELECT and this action makes no change in any item's selection state, XmNselectionCallback(s) is called with reason XmCR_EXTENDED_SELECT and auto_selection_type XmAUTO_NO_CHANGE. ContainerEndToggle(): Simply returns if XmNselectionPolicy is XmSINGLE_SELECT or XmBROWSE_SELECT. If XmNselectionPolicy is XmMULTIPLE_SELECT or XmEXTENDED_SELECT, this action performs the same processing as the ContainerEndSelect() action. ContainerEndTransfer():: If the elapsed time since a ContainerStartTransfer() action has occurred exceeds the time span specified by the display's multiclick time, this action returns. Otherwise, the ContainerPrimaryCopy(), ContainerPrimaryLink(), or ContainerPrimaryMove() action is invoked, depending on the value of the operation parameter saved by ContainerStartTransfer(). ContainerExpandOrCollapse(Left|Right|Collapse|Expand): This action changes the value of the XmNoutlineState of the current focus widget. If the argument value is Collapse or Left, the XmNoutlineState resource value is set to XmCOLLAPSED. If the argument value is Expand or Right, the XmNoutlineState resource value is set to XmEXPANDED. If the argument is Left or Right and the layout is right to left, then the setting of the XmNoutlineState value is reversed from that described in the preceding paragraph. Simply returns if XmNlayoutType is XmSPATIAL. ContainerExtend(): Processing depends on the value of XmNselectionPolicy, as follows: If the selection policy is XmSINGLE_SELECT or XmBROWSE_SELECT, this action returns. If XmNlayoutType is XmSPATIAL, this action returns. If the selection policy is XmMULTIPLE_SELECT, this action sets the selection state of all items between the anchor item and the location cursor to the selection state of the anchor item. If the selection policy is XmEXTENDED_SELECT and the Container is in Normal Mode, this action deselects all items and selects all items between the anchor item and the location cursor. If the selection policy is XmEXTENDED_SELECT and the Container is in Add Mode, this action sets the selection state of all items between the anchor item and the location cursor to the selection state of the anchor item. XmNselectionCallback is called with reason XmCR_MULTIPLE_SELECT or XmCR_EXTENDED_SELECT depending on XmNselectionPolicy. ContainerExtendCursor(Left|Right|Up|Down): Processing depends on the value of XmNselectionPolicy, as follows: If the selection policy is XmSINGLE_SELECT or XmBROWSE_SELECT, this action returns. If XmNlayoutType is XmSPATIAL, this action returns. This action moves the location cursor one item in the indicated direction, if possible. If the value of the argument string is First or Last, this action moves the location cursor to the indicated item. For other values of the argument string, the location cursor is not affected. If the selection policy is XmMULTIPLE_SELECT, this action sets the selection state of all items between the anchor item and the location cursor to the selection state of the anchor item. If the selection policy is XmEXTENDED_SELECT and the Container is in Normal Mode, this action deselects all items and selects all items between the anchor item and the location cursor. If the selection policy is XmEXTENDED_SELECT and the Container is in Add Mode, this action sets the selection state of all items between the anchor item and the location cursor to the selection state of the anchor item. XmNselectionCallback is called with reason XmCR_MULTIPLE_SELECT or XmCR_EXTENDED_SELECT depending on XmNselectionPolicy. ContainerHandleBtn1Down(string) When Display's XmNenableBtn1Transfer resource is not XmOFF, the actions for selection and transfer are integrated on <Btn1>. If the pointer is over an unselected item or background, the item is first selected before the transfer is started. Otherwise, if the item is already selected, the transfer is started. The value of string can be one of the following actions: • ContainerBeginSelect,Copy • ContainerBeginToggle,Copy • ContainerNoop,Link • ContainerBeginExtend,Move ContainerHandleBtn1Motion(string) When Display's XmNenableBtn1Transfer resource is not XmOFF, the actions for selection and transfer are integrated on <Btn1>. When this action is invoked, and a selection is in progress, a drag is performed. Otherwise, the default action as specified in string is performed. The value of string can be ContainerButtonMotion. ContainerHandleBtn1Up(string) If a Button 1 transfer was in progress, then when this action is invoked, that transfer is cancelled. Otherwise, the default action as specified in string is performed. The value of string can be one of the following actions: • ContainerEndSelect • ContainerEndToggle • ContainerEndExtend ContainerHandleBtn2Down(string) When Display's XmNenableBtn1Transfer resource has a value of XmBUTTON2_ADJUST, the actions for extending selection are bound on <Btn2>. Otherwise, the action that is performed depends on the value of string, which can be one of the following actions: • ContainerStartTransfer,Copy • ContainerStartTransfer,Link • ContainerStartTransfer,Move ContainerHandleBtn2Motion(string) When Display's XmNenableBtn1Transfer resource is not XmBUTTON2_ADJUST, and a selection is in progress, a drag is performed. Otherwise, the default action that is performed depends on the value of string, which can be ContainerButtonMotion. ContainerHandleBtn2Up(string) When Display's XmNenableBtn1Transfer resource has a value of XmBUTTON2_ADJUST, this action ends an extend. Otherwise, the action that is performed depends on the value of string, which can be ContainerEndTransfer. ContainerMoveCursor(Left|Right|Up|Down|First|Last): If the argument is Left, Right, Up, or Down, this action moves the location cursor one item in the indicated direction, if possible. If the value of the argument string is First or Last, this action moves the location cursor to the indicated item. Any other arguments are ignored. If XmNselectionPolicy is XmBROWSE_SELECT, or if XmNselectionPolicy is XmEXTENDED_SELECT and the Container is in Normal Mode, this action deselects all items, selects the item at the location cursor, and calls XmNselectionCallback with the reason depending on XmNselectionPolicy. ContainerPrimaryCopy(): This action requests that primary selection data be copied to the Container. This action calls the XmNdestinationCallback procedures for the PRIMARY selection and the XmCOPY operation. By default, the Container does not do any transfer, and copying the selection is the responsibility of the XmNdestinationCallback procedures. ContainerPrimaryLink(): This action requests that primary selection data be linked to the Container. This action calls the XmNdestinationCallback procedures for the PRIMARY selection and the XmLINK operation. By default, the Container does not do any transfer, and linking the selection is the responsibility of the XmNdestinationCallback procedures. ContainerPrimaryMove(): This action requests that primary selection data be copied to the Container and deleted from the primary source. This action calls the XmNdestinationCallback procedures for the PRIMARY selection and the XmMOVE operation. By default, the Container does not do any transfer, and moving the selection is the responsibility of the XmNdestinationCallback procedures. If the transfer is successful, this action then calls the selection owner's XmNconvertCallback procedures for the PRIMARY selection and the DELETE target. ContainerSelect(): Processing depends on the value of XmNselectionPolicy, as follows: If the selection policy is XmSINGLE_SELECT or XmBROWSE_SELECT, this action deselects all items and selects the item at the location cursor. If the selection policy is XmMULTIPLE_SELECT, this action toggles the selection state of the item at the location cursor. This item becomes the anchor item for further selections. If the selection policy is XmEXTENDED_SELECT and the Container is in Normal Mode, this action deselects all items and selects the item at the location cursor. If the selection policy is XmEXTENDED_SELECT and the Container is in Add Mode, this action toggles the selection state of the item at the location cursor. The selected/toggled item becomes the anchor item for further selections. XmNselectionCallback is called with the reason depending on XmNselectionPolicy. ContainerSelectAll(): If XmNselectionPolicy is XmSINGLE_SELECT or XmBROWSE_SELECT, this action deselects all items and selects the item at the location cursor position. If XmNselectionPolicy is XmMULTIPLE_SELECT or XmEXTENDED_SELECT, this action selects all items. XmNselectionCallback is called with the reason depending on the value of XmNselectionCallback. ContainerStartTransfer(Copy|Move|Link): This action saves the event and the operation specified in the argument string for use by subsequent actions. If no ContainerEndTransfer() actions occur within the time span specified by the display's multiclick time and if XmNlayoutType is XmSPATIAL, this action creates a DragContext and starts a drag transfer by using string to specify the transfer operation. If no argument string is specified, Copy is the default value. Unless default drag and drop behavior has been overridden by a XmNconvertCallback procedure, if the drop operation occurs within the Container, then the item(s) being dragged are relocated at the position of the drop operation. If the item targeted by the Drag operation is not in the selected state, then only that item is moved. If the item is in the selected state, however, all items in the selected state are moved. ContainerToggleMode(): If XmNselectionPolicy is XmEXTENDED_SELECT, this action toggles the Container between Normal Mode and Add Mode.
Additional BehaviorThe Container widget has the following additional behavior: <Btn1Down>(2+) If a button click is followed by another button click within the time span specified by the display's multiclick time, the Container interprets that as a double-click and calls the XmNdefaultActionCallback callbacks. <FocusIn>: If the focus policy is explicit, sets the focus and draws the location cursor. <FocusOut>: If the focus policy is explicit, removes the focus and erases the location cursor.
