NAMEXmRowColumn — The RowColumn widget class .iX "XmRowColumn" .iX "widget class" "RowColumn"
SYNOPSIS#include <Xm/RowColumn.h>
DESCRIPTIONThe RowColumn widget is a general purpose RowColumn manager capable of containing any widget type as a child. In general, it requires no special knowledge about how its children function and provides nothing beyond support for several different layout styles. However, it can be configured as a menu, in which case, it expects only certain children, and it configures to a particular layout. The menus supported are MenuBar, Pulldown or Popup menu panes, and OptionMenu. RowColumn uses the XmQTmenuSavvy trait and holds the XmQTmenuSystem trait. The type of layout performed is controlled by how the application has set the various layout resources. It can be configured to lay out its children in either rows or columns. In addition, the application can specify how the children are laid out, as follows: • The children are packed tightly together into either rows or columns • Each child is placed in an identically sized box (producing a symmetrical look) • A specific layout (the current x and y positions of the children control their location) In addition, the application has control over both the spacing that occurs between each row and column and the margin spacing present between the edges of the RowColumn widget and any children that are placed against it. The default XmNinsertPosition procedure for the RowColumn returns the value of XmNpositionIndex if one has been specified for the child. Otherwise, this procedure returns the number of children in the RowColumn's XmNnumChildren list. In a MenuBar, Pulldown menu pane, or Popup menu pane the default for the XmNshadowThickness resource is 2. In an OptionMenu or a WorkArea, (such as a RadioBox or CheckBox) this resource is not applicable and its use is undefined. If an application wishes to place a 3-D shadow around an OptionMenu or WorkArea, it can create the RowColumn as a child of a Frame widget. In a MenuBar, Pulldown menu pane, or Popup menu pane the XmNnavigationType resource is not applicable and its use is undefined. In a WorkArea, the default for XmNnavigationType is XmTAB_GROUP. In an OptionMenu the default for XmNnavigationType is XmNONE. In a MenuBar, Pulldown menu pane, or Popup menu pane the XmNtraversalOn resource is not applicable and its use is undefined. In an OptionMenu or WorkArea, the default for XmNtraversalOn is True. If the parent of the RowColumn is a MenuShell, the XmNmappedWhenManaged resource is forced to False when the widget is realized. The user can specify resources in a resource file for the automatically created widgets and gadgets of an OptionMenu. The following list identifies the names of these widgets (or gadgets) and the associated OptionMenu areas. Option Menu Label Gadget OptionLabel Option Menu Cascade Button OptionButton For the Popup and Pulldown Menupanes, popup and pulldown menus have particular behaviors when the <Btn1> button is pressed outside the menus. These behaviors are summarized here. When there is already a popped up menu, a user can either press <Btn1> in the same area as the popped up menu, or can press <Btn1> in another area that should have a menu popped up. When <Btn1> is pressed in the same area as the already popped up menu, that menu is unposted. If <Btn1> is pressed in a different area, the associated popup menu is posted for the new area. Note, however, that if the XmNpopupHandlerCallback of either XmManager or XmPrimitive is available, then the callback may override these default behaviors. For pulldown menus, a user can press <Btn1> on the Cascade button to post the pulldown menu, then click on it again. Upon the second click, the pulldown menu is unposted. Popup menus are not allowed to have NULL parents.
Pulldown and Popup menu panes support tear-off menus, which enable the user to retain a menu pane on the display to facilitate subsequent menu selections. A menu pane that can be torn-off is identified by a tear-off button that spans the width of the menu pane and displays a dashed line. A torn-off menu pane contains a window manager system menu icon and a title bar. The window title displays the label of the cascade button that initiated the action when the label type is XmSTRING. If the label contains a pixmap the window title is empty. A tear-off menu from a Popup menu pane also displays an empty title. Tear-off menus should not be shared. The user can tear off a menu pane using the mouse or keyboard. Clicking <Btn1> or pressing <osfActivate> (or <osfSelect>) on the tear-off button, tears off the menu pane at the current position. Pressing <Btn2> on the tear-off button tears off the menu pane and allows the user to drag the torn-off menu to a new position designated by releasing the mouse button. Tearing off a menu pane unposts the current active menu. Only one tear-off copy for each menu pane is allowed. Subsequent tear-off actions of a torn menu pane unpost the existing copy first. The name of the tear-off button of a torn-off menu pane is TearOffControl. The name can be used to set resources in a resource file. An application can also obtain the tear-off button itself using XmGetTearOffControl and then set resource values by calling XtSetValues. The tear-off button has Separator-like behavior. Its appearance can be specified with the following tear-off button resources: XmNbackground, XmNbackgroundPixmap, XmNbottomShadowColor, XmNforeground, XmNheight, XmNmargin, XmNseparatorType, XmNshadowThickness, and XmNtopShadowColor. Refer to the XmSeparator reference page for a complete description of each of these resources. The XmNtearOffModel, XmNtearOffMenuActivateCallback, and XmNtearOffMenuDeactivateCallback are RowColumn resources that affect tear-off menu behavior. The XmNtearOffTitle resource enables the application to specify the tear-off menu's title if the menu is torn off. By default, menus do not tear off. Setting the XmNtearOffModel resource to XmTEAR_OFF_ENABLED enables tear-off functionality. There is no resource converter preregistered for XmNtearOffModel. To allow tear-off functionality to be enabled through the resource database, call the function XmRepTypeInstallTearOffModelConverter. Tear-off menu focus policy follows standard window manager policy. It is recommended that the startupKeyFocus and autoKeyFocus mwm resources be set to True.
DescendantsRowColumn automatically creates the descendants shown in the following table. An application can use XtNameToWidget to gain access to the named descendant. In addition, a user or an application can use the named descendant when specifying resource values.

ClassesRowColumn inherits behavior, resources, and traits from Core, Composite, Constraint, and XmManager classes. The class pointer is xmRowColumnWidgetClass. The class name is XmRowColumn.
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 if 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).

Setting XmNadjustLast to False disables this feature. XmNadjustMargin Specifies whether the inner minor margins of all items contained within the RowColumn widget are forced to the same value. The inner minor margin corresponds to the XmNmarginLeft, XmNmarginRight, XmNmarginTop, and XmNmarginBottom resources supported by XmLabel and XmLabelGadget. A horizontal orientation causes XmNmarginTop and XmNmarginBottom for all items in a particular row to be forced to the same value; the value is the largest margin specified for one of the Label items. A vertical orientation causes XmNmarginLeft and XmNmarginRight for all items in a particular column to be forced to the same value; the value is the largest margin specified for one of the Label items. This keeps all text within each row or column lined up with all other text in its row or column. If XmNrowColumnType is either XmMENU_POPUP or XmMENU_PULLDOWN and this resource is True, only button children have their margins adjusted. XmNentryAlignment Specifies the alignment type for children that are subclasses of XmLabel or XmLabelGadget when XmNisAligned is enabled. The following are textual alignment types: • XmALIGNMENT_BEGINNING (default) • XmALIGNMENT_CENTER • XmALIGNMENT_END See the description of XmNalignment in the XmLabel(3) reference page for an explanation of these actions. XmNentryBorder Imposes a uniform border width upon all RowColumn's children. The default value is 0 (zero), which disables the feature. XmNentryCallback Disables the XmNactivateCallback and XmNvalueChangedCallback callbacks for all CascadeButton, DrawnButton, PushButton, and ToggleButton widgets and gadgets contained within the RowColumn widget. If the application supplies this resource, the XmNactivateCallback and XmNvalueChangedCallback callbacks are then revectored to the XmNentryCallback callbacks. This allows an application to supply a single callback routine for handling all items contained in a RowColumn widget. The callback reason is XmCR_ACTIVATE. If the application does not supply this resource, the XmNactivateCallback and XmNvalueChangedCallback callbacks for each item in the RowColumn widget work as normal. The application must supply this resource when this widget is created. Changing this resource using the XtSetValues is not supported. XmNentryClass Specifies the only widget class that can be added to the RowColumn widget; this resource is meaningful only when the XmNisHomogeneous resource is set to True. Both widget and gadget variants of the specified class may be added to the widget. When XmCreateRadioBox is called or when XmNrowColumnType is set to XmWORK_AREA and XmNradioBehavior is True, the default value of XmNentryClass is xmToggleButtonGadgetClass. When XmNrowColumnType is set to XmMENU_BAR, the value of XmNentryClass is forced to xmCascadeButtonWidgetClass. XmNentryVerticalAlignment Specifies the type of vertical alignment for children that are subclasses of XmLabel, XmLabelGadget, and XmText. This resource is invalid if XmNorientation is XmVERTICAL and XmNpacking is XmPACK_TIGHT, because this layout preserves variable heights among the children. The vertical alignment types include: XmALIGNMENT_BASELINE_BOTTOM Causes the bottom baseline of all children in a row to be aligned. This resource is applicable only when all children in a row contain textual data. XmALIGNMENT_BASELINE_TOP Causes the top baseline of all children in a row to be aligned. This resource is applicable only when all children in a row contain textual data. XmALIGNMENT_CONTENTS_BOTTOM Causes the bottom of the contents (text or pixmap) of all children in a row to be aligned. XmALIGNMENT_CENTER Causes the center of all children in a row to be aligned. XmALIGNMENT_CONTENTS_TOP Causes the top of the contents (text or pixmap) of all children in a row to be aligned. XmNisAligned Specifies text alignment for each item within the RowColumn widget; this applies only to items that are subclasses of XmLabel or XmLabelGadget. However, if the item is a Label widget or gadget and its parent is either a Popup menu pane or a Pulldown menu pane, alignment is not performed; the Label is treated as the title within the menu pane, and the alignment set by the application is not overridden. XmNentryAlignment controls the type of textual alignment. XmNisHomogeneous Indicates whether the RowColumn widget should enforce exact homogeneity among the items it contains; if this resource is set to True, only the widgets that are of the class indicated by XmNentryClass are allowed as children of the RowColumn widget. This is most often used when creating a MenuBar. Attempting to insert a child that is not a member of the specified class generates a warning message. In a MenuBar, the value of XmNisHomogeneous is forced to True. In an OptionMenu, the value is forced to False. When XmCreateRadioBox is called the default value is True. Otherwise, the default value is False. XmNlabelString When XmNrowColumnType is set to XmMENU_OPTION, this resource points to a text string that displays the label with respect to the selection area. The positioning of the label relative to the selection area depends on the layout direction in the horizontal orientation. This resource is not meaningful for all other RowColumn types. If the application wishes to change the label after creation, it must get the LabelGadget ID (XmOptionLabelGadget) and call XtSetValues on the LabelGadget directly. The default value is no label. XmNmapCallback Specifies a widget-specific callback function that is invoked when the window associated with the RowColumn widget is about to be mapped. The callback reason is XmCR_MAP. XmNmarginHeight Specifies the amount of blank space between the top edge of the RowColumn widget and the first item in each column, and the bottom edge of the RowColumn widget and the last item in each column. The default value is 0 (zero) for Pulldown and Popup menu panes, and 3 pixels for other RowColumn types. XmNmarginWidth Specifies the amount of blank space between the left edge of the RowColumn widget and the first item in each row, and the right edge of the RowColumn widget and the last item in each row. The default value is 0 (zero) for Pulldown and Popup menu panes, and 3 pixels for other RowColumn types. XmNmenuAccelerator This resource is useful only when the RowColumn widget has been configured to operate as a Popup menu pane or a MenuBar. The format of this resource is similar to the left side specification of a translation string, with the limitation that it must specify a key event. For a Popup menu pane, when the accelerator is typed by the user, the Popup menu pane is posted. For a MenuBar, when the accelerator is typed by the user, the first item in the MenuBar is highlighted, and traversal is enabled in the MenuBar. The default for a Popup menu pane is <osfMenu>. The default for a MenuBar is <osfMenuBar>. Setting the XmNpopupEnabled resource to False disables the accelerator. XmNmenuHelpWidget Specifies the widget ID for the CascadeButton, which is treated as the Help widget if XmNrowColumnType is set to XmMENU_BAR. Which corner of the MenuBar the Help widget is placed at depends on the XmNlayoutDirection resource of the widget. If the RowColumn widget is any type other than XmMENU_BAR, this resource is not meaningful. XmNmenuHistory Specifies the widget ID of the last menu entry to be activated. It is also useful for specifying the current selection for an OptionMenu. If XmNrowColumnType is set to XmMENU_OPTION, the specified menu item is positioned under the cursor when the menu is displayed. If the RowColumn widget has the XmNradioBehavior resource set to True, the widget field associated with this resource contains the widget ID of the last ToggleButton or ToggleButtonGadget to change from unselected to selected. The default value is the widget ID of the first child in the widget. XmNmenuPost Specifies an X event description indicating a button event that posts a menu system. The default for XmMENU_POPUP is BMenu Press. The default for XmMENU_OPTION, XmMENU_BAR, and XmWORK_AREA is <Btn1> Press. The XmNmenuPost resource for pulldowns should be consistent with that of the top-level parent menu (although the event type is ignored). Setting this resource to BTransfer Press will conflict with drag and drop operations, which use BTransfer Press as a default button binding. Therefore, this resource cannot be BTransfer Press. XmNmnemonic This resource is useful only when XmNrowColumnType is set to XmMENU_OPTION. It specifies a keysym for a key that, when pressed by the user along with the MAlt modifier, posts the associated Pulldown menu pane. The first character in the OptionMenu label string that exactly matches the mnemonic in the character set specified in XmNmnemonicCharSet is underlined. The user can post the menu by pressing either the shifted or the unshifted mnemonic key. The default is no mnemonic. XmNmnemonicCharSet Specifies the character set of the mnemonic for an OptionMenu. The default is XmFONTLIST_DEFAULT_TAG. If the RowColumn widget is any type other than XmMENU_OPTION, this resource is not meaningful. XmNnumColumns Specifies the number of minor dimension extensions that are made to accommodate the entries; this attribute is meaningful only when XmNpacking is set to XmPACK_COLUMN. For vertically oriented RowColumn widgets, this attribute indicates how many columns are built; the number of entries per column is adjusted to maintain this number of columns, if possible. For horizontally oriented RowColumn widgets, this attribute indicates how many rows are built. The default value is 1. In an OptionMenu the value is forced to 1. The value must be greater than 0 (zero). XmNorientation Determines whether RowColumn layouts are row-major or column-major. In a column-major layout, the children of the RowColumn are laid out in columns within the widget. In a row-major layout the children of the RowColumn are laid out in rows. The direction of the horizontal layout in the row-major layout (from left or right), and the wrapping in the column-major layout (vertical), depend on the XmNlayoutDirection resource of the widget. The XmVERTICAL resource value selects a column-major layout. XmHORIZONTAL selects a row-major layout. When creating a MenuBar or an OptionMenu, the default is XmHORIZONTAL. Otherwise, the default value is XmVERTICAL. The results of specifying a value of XmVERTICAL for a MenuBar are undefined. XmNpacking Specifies how to pack the items contained within a RowColumn widget. This can be set to XmPACK_TIGHT, XmPACK_COLUMN or XmPACK_NONE. When a RowColumn widget packs the items it contains, it determines its major dimension using the value of the XmNorientation resource. XmPACK_TIGHT indicates that given the current major dimension (for example, vertical if XmNorientation is XmVERTICAL), entries are placed one after the other until the RowColumn widget must wrap. RowColumn wraps when there is no room left for a complete child in that dimension. Wrapping occurs by beginning a new row or column in the next available space. Wrapping continues, as often as necessary, until all of the children are laid out. In the vertical dimension (columns), boxes are set to the same width; in the horizontal dimension (rows), boxes are set to the same depth. Each entry's position in the major dimension is left unaltered (for example, XmNy is left unchanged when XmNorientation is XmVERTICAL); its position in the minor dimension is set to the same value as the greatest entry in that particular row or column. The position in the minor dimension of any particular row or column is independent of all other rows or columns. XmPACK_COLUMN indicates that all entries are placed in identically sized boxes. The boxes are based on the largest height and width values of all the children widgets. The value of the XmNnumColumns resource determines how many boxes are placed in the major dimension, before extending in the minor dimension. XmPACK_NONE indicates that no packing is performed. The x and y attributes of each entry are left alone, and the RowColumn widget attempts to become large enough to enclose all entries. When XmCreateRadioBox is called or when XmNrowColumnType is set to XmWORK_AREA and XmNradioBehavior is True, the default value of XmNpacking is XmPACK_COLUMN. In an OptionMenu the value is initialized to XmPACK_TIGHT. Otherwise, the value defaults to XmPACK_TIGHT. XmNpopupEnabled Allows the menu system to enable keyboard input (accelerators and mnemonics) defined for the Popup menu pane and any of its submenus. The Popup menu pane needs to be informed whenever its accessibility to the user changes because posting of the Popup menu pane is controlled by the application. This resource can take four values, including: XmPOPUP_KEYBOARD Specifies that the keyboard input—accelerators and mnemonics—defined for the Popup menu pane and any of its submenus is enabled. This is the default. XmPOPUP_DISABLED Specifies that the keyboard input is disabled. XmPOPUP_AUTOMATIC Specifies that the keyboard is enabled for automatic popup menus. XmPOPUP_AUTOMATIC_RECURSIVE Specifies that the keyboard is enabled for recursive automatic popup menus. XmNradioAlwaysOne If True, forces the active ToggleButton or ToggleButtonGadget to be automatically selected after having been unselected (if no other toggle was activated). If False, the active toggle may be unselected. The default value is True. This resource is important only when XmNradioBehavior is True. The application can always add and subtract toggles from RowColumn regardless of the selected/unselected state of the toggle. The application can also manage and unmanage toggle children of RowColumn at any time regardless of state. Therefore, the application can sometimes create a RowColumn that has XmNradioAlwaysOne set to True and none of the toggle children selected. The result is undefined if the value of this resource is True and the application sets more than one ToggleButton at a time. XmNradioBehavior Specifies a Boolean value that when True, indicates that the RowColumn widget should enforce a RadioBox-type behavior on all of its children that are ToggleButtons or ToggleButtonGadgets. When the value of this resource is True, XmNindicatorType defaults to XmONE_OF_MANY for ToggleButton and ToggleButtonGadget children. RadioBox behavior dictates that when one toggle is selected and the user selects another toggle, the first toggle is unselected automatically. The RowColumn usually does not enforce this behavior if the application, rather than the user, changes the state of a toggle. The RowColumn does enforce this behavior if a toggle child is selected with XmToggleButtonSetState or XmToggleButtonGadgetSetState with a notify argument of True. When XmCreateRadioBox is called, the default value of XmNradioBehavior is True. Otherwise, the default value is False. XmNresizeHeight Requests a new height if necessary, when set to True. When this resource is set to False, the widget does not request a new height regardless of any changes to the widget or its children. XmNresizeWidth Requests a new width if necessary, when set to True. When set to False, the widget does not request a new width regardless of any changes to the widget or its children. XmNrowColumnType Specifies the type of RowColumn widget to be created. It is a nonstandard resource that cannot be changed after it is set. If an application uses any of the convenience routines, except XmCreateRowColumn, this resource is automatically forced to the appropriate value by the convenience routine. If an application uses the Xt Intrinsics API to create its RowColumn widgets, it must specify this resource itself. The set of possible settings for this resource are • XmWORK_AREA (default) • XmMENU_BAR • XmMENU_PULLDOWN • XmMENU_POPUP • XmMENU_OPTION This resource cannot be changed after the RowColumn widget is created. Any changes attempted through XtSetValues are ignored. The value of this resource is used to determine the value of a number of other resources. The descriptions of RowColumn resources explain this when it is the case. The resource XmNnavigationType, inherited from XmManager, is changed to XmNONE if XmNrowColumnType is XmMENU_OPTION. XmNspacing Specifies the horizontal and vertical spacing between items contained within the RowColumn widget. The default value is 3 pixels for XmOPTION_MENU and XmWORK_AREA and 0 (zero) for other RowColumn types. XmNsubMenuId Specifies the widget ID for the Pulldown menu pane to be associated with an OptionMenu. This resource is useful only when XmNrowColumnType is set to XmMENU_OPTION. The default value is NULL. XmNtearOffMenuActivateCallback Specifies the callback list that notifies the application when the tear-off menu pane is about to be activated. It precedes the tear-off's map callback. Use this resource when your application has shared menu panes and when the torn-off menu can have two or more parents that can have opposing sensitivity states for the same menu item. This resource enables the application to track whether a menu item is sensitive or insensitive and to set the state to the original parent's menu item state when the torn-off menu is reposted. The application can use XmGetPostedFromWidget to determine from which parent the menu was torn. The callback reason is XmCR_TEAR_OFF_ACTIVATE. The default is NULL. XmNtearOffMenuDeactivateCallback Specifies the callback list that notifies the application when the tear-off menu pane is about to be deactivated. It follows the tear-off's unmap callback. Use this resource when your application has shared menu panes and when the torn-off menu can have two or more parents that can have opposing sensitivity states for the same menu item. This resource enables the application to track whether a menu item is sensitive or insensitive and to set the state to the original parent's menu item state when the torn-off menu is reposted. The application can use XmGetPostedFromWidget to determine from which parent the menu was torn. The callback reason is XmCR_TEAR_OFF_DEACTIVATE. The default is NULL. XmNtearOffModel Indicates whether tear-off functionality is enabled or disabled when XmNrowColumnType is set to XmMENU_PULLDOWN or XmMENU_POPUP. The values are XmTEAR_OFF_ENABLED or XmTEAR_OFF_DISABLED (default value). This resource is invalid for type XmMENU_OPTION; however, it does affect any pulldown submenus within an OptionMenu. The function XmRepTypeInstallTearOffModelConverter installs a resource converter for this resource. XmNtearoffTitle Used by the TearOff shell to set the title for the window manager to display. XmNunmapCallback Specifies a list of callbacks that is called after the window associated with the RowColumn widget has been unmapped. The callback reason is XmCR_UNMAP. The default value is NULL. XmNwhichButton This resource is obsolete; it has been replaced by XmNmenuPost and is present for compatibility with older releases of Motif. This resource cannot be 2. XmRowColumn Constraint Resource Set NameClassTypeDefaultAccess XmNpositionIndexXmCPositionIndexshortXmLAST_POSITIONCSG XmNpositionIndex Specifies the position of the widget in its parent's list of children (the value of the XmNchildren resource). The value is an integer that is no less than 0 (zero) and no greater than the number of children in the list at the time the value is specified. A value of 0 (zero) means that the child is placed at the beginning of the list. The value can also be specified as XmLAST_POSITION (the default), which means that the child is placed at the end of the list. Any other value is ignored. XtGetValues returns the position of the widget in its parent's child list at the time of the call to XtGetValues. When a widget is inserted into its parent's child list, the positions of any existing children that are greater than or equal to the specified widget's XmNpositionIndex are increased by 1. The effect of a call to XtSetValues for XmNpositionIndex is to remove the specified widget from its parent's child list, decrease by 1 the positions of any existing children that are greater than the specified widget's former position in the list, and then insert the specified widget into its parent's child list as described in the preceding sentence.

It specifies a list of compound strings to use as labels for the buttons created. The list contains one element for each button, separator, and title created. XmNbuttonSet This resource is for use with the simple menu creation routines. It specifies which button of a RadioBox or OptionMenu Pulldown submenu is initially set. The value is an integer n indicating the nth ToggleButtonGadget specified for a RadioBox or the nth PushButtonGadget specified for an OptionMenu Pulldown submenu. The first button specified is number 0. The value must not be negative. XmNbuttonType This resource is for use with the simple menu creation routines. It specifies a list of button types associated with the buttons to be created. The list contains one element for each button, separator, and title created. If this resource is not specified, each button in a MenuBar is a CascadeButtonGadget, each button in a RadioBox or CheckBox is a ToggleButtonGadget, and each button in any other type of RowColumn widget is a PushButtonGadget. Each button type is of type XmButtonType, an enumeration with the following possible values: XmCASCADEBUTTON Specifies a CascadeButtonGadget for a MenuBar, Popup menu pane, or Pulldown menu pane. XmCHECKBUTTON Specifies a ToggleButtonGadget for a CheckBox, Popup menu pane, or Pulldown menu pane. XmDOUBLE_SEPARATOR Specifies a SeparatorGadget for a Popup menu pane, Pulldown menu pane, or OptionMenu Pulldown submenu. The separator type is XmDOUBLE_LINE. XmPUSHBUTTON Specifies a PushButtonGadget for a Popup menu pane, Pulldown menu pane, or OptionMenu Pulldown submenu. XmRADIOBUTTON Specifies a ToggleButtonGadget for a RadioBox, Popup menu pane, or Pulldown menu pane. XmSEPARATOR Specifies a SeparatorGadget for a Popup menu pane, Pulldown menu pane, or OptionMenu Pulldown submenu. XmTITLE Specifies a LabelGadget used as a title for a Popup menu pane or Pulldown menu pane. XmNoptionLabel This resource is for use with the simple menu creation routines. It specifies a compound string for the label string to be used on the left side of an OptionMenu. XmNoptionMnemonic This resource is for use with the simple menu creation routines. It specifies a keysym for a key that, when pressed by the user along with the MAlt modifier, posts the associated Pulldown menu pane for an OptionMenu. XmNpostFromButton This resource is for use with the simple menu creation routines. For a Pulldown menu pane, it specifies the button in the parent to which the submenu is attached. The menu is then posted from this button. The value is an integer n indicating the nth CascadeButton or CascadeButtonGadget specified for the parent of the Pulldown menu pane. The first button specified is number 0. The value must not be negative. XmNsimpleCallback This resource is for use with the simple menu creation routines. It specifies a callback procedure to be called when a button is activated or when its value changes. This callback function is added to each button after creation. For a CascadeButtonGadget or a PushButtonGadget, the callback is added as the button's XmNactivateCallback, and it is called when the button is activated. For a ToggleButtonGadget, the callback is added as the button's XmNvalueChangedCallback, and it is called when the button's value changes. The button number is passed in the client_data field.

Callback InformationA pointer to the following structure is passed to each callback: typedef struct
{
int reason;
XEvent * event;
Widget widget;
char * data;
char * callbackstruct;
} XmRowColumnCallbackStruct;reason Indicates why the callback was invoked event Points to the XEvent that triggered the callback The following fields apply only when the callback reason is XmCR_ACTIVATE; for all other callback reasons, these fields are set to NULL. The XmCR_ACTIVATE callback reason is generated only when the application has supplied an entry callback, which overrides any activation callbacks registered with the individual RowColumn items. widget Is set to the widget ID of the RowColumn item that has been activated data Contains the client-data value supplied by the application when the RowColumn item's activation callback was registered callbackstruct Points to the callback structure generated by the RowColumn item's activation callback
TranslationsXmRowColumn translations depend on the value of the XmNrowColumnType resource. If XmNrowColumnType is set to XmWORK_AREA, XmRowColumn inherits translations from XmManager. If XmNrowColumnType is set to XmMENU_OPTION, XmRowColumn inherits traversal, <osfActivate>, and <osfCancel> translations from XmManager and has the following additional translations. 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). For a complete description of the format, please refer to the X Toolkit Instrinsics Documentation. <Btn2Down>: MenuGadgetDrag() c<Btn1Down>: MenuGadgetTraverseCurrent() c<Btn1Up>: MenuGadgetTraverseCurrentUp() ∼c<BtnDown>: MenuBtnDown() ∼c<BtnUp>: MenuBtnUp() :<Key><osfHelp>: MenuHelp() The translations for XmRowColumn if XmNrowColumnType is set to XmMENU_BAR XmMENU_PULLDOWN, or XmMENU_POPUP are described in the following list. In a Popup menu system, <Btn3> also performs the <Btn1> actions. :<Key><osfHelp>: MenuHelp() :<Key><osfLeft>: MenuGadgetTraverseLeft() :<Key><osfRight>: MenuGadgetTraverseRight() :<Key><osfUp>: MenuGadgetTraverseUp() :<Key><osfDown>: MenuGadgetTraverseDown()
Action RoutinesThe XmRowColumn action routines are Help(): Calls the callbacks for XmNhelpCallback if any exist. If there are no help callbacks for this widget, this action calls the help callbacks for the nearest ancestor that has them. ManagerGadgetSelect(): When a gadget child of the menu has the focus, invokes the gadget child's behavior associated with <osfSelect>. This generally has the effect of unposting the menu hierarchy and arming and activating the gadget, except that, for a CascadeButtonGadget with a submenu, it posts the submenu. MenuBtnDown(): When a gadget child of the menu has focus, invokes the gadget child's behavior associated with <Btn1Down>. This generally has the effect of unposting any menus posted by the parent menu, enabling mouse traversal in the menu, and arming the gadget. For a CascadeButtonGadget with a submenu, it also posts the associated submenu. MenuBtnUp(): When a gadget child of the menu has focus, invokes the gadget child's behavior associated with <Btn1Up>. This generally has the effect of unposting the menu hierarchy and activating the gadget, except that for a CascadeButtonGadget with a submenu, it posts the submenu and enables keyboard traversal in the menu. MenuGadgetEscape(): In a top-level Pulldown MenuPane from a MenuBar, unposts the menu, disarms the MenuBar CascadeButton and the MenuBar, and, when the shell's keyboard focus policy is XmEXPLICIT, restores keyboard focus to the widget that had the focus before the MenuBar was entered. In other Pulldown MenuPanes, unposts the menu. In a Popup MenuPane, unposts the menu and, when the shell's keyboard focus policy is XmEXPLICIT, restores keyboard focus to the widget from which the menu was posted. In a TearOff MenuPane that has no submenus posted, dismisses the menu; otherwise, if one or more submenus are posted, unposts the last menu pane. MenuGadgetTraverseDown(): If the current menu item has a submenu and is in a MenuBar, then this action posts the submenu, disarms the current menu item, and arms the submenu's first traversable menu item. If the current menu item is in a MenuPane, then this action disarms the current menu item and arms the item below it. This action wraps within the MenuPane. The direction of the wrapping depends on the XmNlayoutDirection resource. MenuGadgetTraverseLeft(): When the current menu item is in a MenuBar, this action disarms the current item and arms the MenuBar item to the left. This action wraps within the MenuBar. In MenuPanes, if the current menu item is not at the left edge of a MenuPane, this action disarms the current item and arms the item to its left. If the current menu item is at the left edge of a submenu attached to a MenuBar item, then this action unposts the submenu and traverses to the MenuBar item to the left, wrapping if necessary. If that MenuBar item has a submenu, it posts the submenu and arms the first traversable item in the submenu. If the current menu item is at the left edge of a submenu not directly attached to a MenuBar item, then this action unposts the current submenu only. In Popup or Torn-off MenuPanes, when the current menu item is at the left edge, this action wraps within the MenuPane. If the current menu item is at the left edge of the MenuPane and not in the top row, this action wraps to the rightmost menu item in the row above. If the current menu item is in the upper, leftmost corner, this action wraps to the tear-off control, if present, or else it wraps to the bottom, rightmost menu item in the MenuPane. The preceding description applies when the XmNlayoutDirection horizontal direction is XmLEFT_TO_RIGHT. If the XmNlayoutDirection horizontal direction is XmRIGHT_TO_LEFT, then the following applies. If the current menu item is in a MenuBar, then this action disarms the current item and arms the MenuBar item to the left. This action wraps within the MenuBar. In MenuPanes, if the current menu item is a CascadeButton, then this action posts its associated submenu. If the current menu item is not a CascadeButton and is not at the left edge of a MenuPane, this action disarms the current item and arms the item to its left, wrapping if necessary. If the current menu item is not a CascadeButton and is at the left edge of a submenu that is a descendent of a MenuBar, then this action unposts all submenus and traverses to the MenuBar item to the left. If that MenuBar item has a submenu, it posts the submenu and arms the submenu's first traversable item. In Popup or Torn-off menus, if the current menu item is not a CascadeButton and is at the left edge of a row (except the bottom row), this action wraps to the rightmost menu item in the row below. If the current menu item is not a CascadeButton and is in the bottom, leftmost corner of a Popup or Pulldown MenuPane, this action wraps to the tear-off control, if present, or else it wraps to the top, rightmost menu item of the MenuPane. MenuGadgetTraverseRight(): If the current menu item is in a MenuBar, then this action disarms the current item and arms the MenuBar item to the right. This action wraps within the MenuBar. In MenuPanes, if the current menu item is a CascadeButton, then this action posts its associated submenu. If the current menu item is not a CascadeButton and is not at the right edge of a MenuPane, this action disarms the current item and arms the item to its right, wrapping if necessary. If the current menu item is not a CascadeButton and is at the right edge of a submenu that is a descendent of a MenuBar, then this action unposts all submenus and traverses to the MenuBar item to the right. If that MenuBar item has a submenu, it posts the submenu and arms the submenu's first traversable item. In Popup or Torn-off menus, if the current menu item is not a CascadeButton and is at the right edge of a row (except the bottom row), this action wraps to the leftmost menu item in the row below. If the current menu item is not a CascadeButton and is in the bottom, rightmost corner of a Popup or Pulldown MenuPane, this action wraps to the tear-off control, if present, or else it wraps to the top, leftmost menu item of the MenuPane. The preceding description applies when the XmNlayoutDirection horizontal direction is XmLEFT_TO_RIGHT. If the XmNlayoutDirection horizontal direction is XmRIGHT_TO_LEFT, then the following applies. When the current menu item is in a MenuBar, this action disarms the current item and arms the MenuBar item to the left. This action wraps within the MenuBar. In MenuPanes, if the current menu item is not at the right edge of a MenuPane, this action disarms the current item and arms the item to its right. If the current menu item is at the right edge of a submenu attached to a MenuBar item, then this action unposts the submenu and traverses to the MenuBar item to the right, wrapping if necessary. If that MenuBar item has a submenu, it posts the submenu and arms the first traversable item in the submenu. If the current menu item is at the right edge of a submenu not directly attached to a MenuBar item, then this action unposts the current submenu only. In Popup or Torn-off MenuPanes, when the current menu item is at the right edge, this action wraps within the MenuPane. If the current menu item is at the right edge of the MenuPane and not in the top row, this action wraps to the leftmost menu item in the row above. If the current menu item is in the upper, rightmost corner, this action wraps to the tear-off control, if present, or else it wraps to the bottom, leftmost menu item in the MenuPane. MenuGadgetTraverseUp(): When the current menu item is in a MenuPane, then this action disarms the current menu item and arms the item above it. This action wraps within the MenuPane. The direction of the wrapping depends on the XmNlayoutDirection resource.
Related BehaviorThe following menu functions are available: <osfMenuBar>: In any non-popup descendant of a MenuBar's parent, excluding the MenuBar itself, this action enables keyboard traversal and moves keyboard focus to the first item in the MenuBar. In the MenuBar or any menu cascaded from it, this action unposts the menu hierarchy and, when the shell's keyboard focus policy is XmEXPLICIT, restores focus to the widget that had the focus when the menu system was entered. <osfMenu>: Pops up the menu associated with the control that has the keyboard focus. Enables keyboard traversal in the menu. In the Popup menu system or any menu cascaded from it, this action unposts the menu hierarchy and, when the shell's keyboard focus policy is XmEXPLICIT, restores focus to the widget that had the focus when the menu system was entered.
