NAME

Traits

— Lists the traits used by the Motif Toolkit. .iX "Traits"

DESCRIPTION

A trait is a characteristic of a widget. A widget holding a particular trait is announcing a particular ability to other widgets. The following table summarizes the standard Motif traits.

Purpose of Each Trait
Trait Name	A Widget Holding This Trait Can Do The Following:

XmQTaccessTextual	Display one primary text parcel.

XmQTactivatable	Become a command button in a dialog box.

XmQTcareParentVisual	Borrow its parent's visual information.

XmQTcontainer	Manage container item children.

XmQTcontainerItem	Become a child of a container widget.

XmQTdialogShellSavvy	Become a child of a DialogShell.

XmQTjoinSide	Attach itself to one side of a suitable parent.

XmQTmenuSavvy	Become a menu child.

XmQTmenuSystem	Manage a menu system.

XmQTnavigator	Act as a navigator to a scrollable widget.

XmQTscrollFrame	Handle one or more navigator widgets.

XmQTspecifyRenderTable	Supply the names of its default render tables.

XmQTtakesDefault	Change its appearance to show that it is the default button.

XmQTtransfer	Transfer data to other widgets and/or receive data from other widgets

Traits are not often used in Motif application programs. However, traits are very important to widget writers. For complete details on traits, see the Motif Widget Writer's Guide

The following table lists the names of all widgets and gadgets in the standard Motif widget set that hold a particular trait. For example, the following table shows that the XmQTcontainerItem

trait is held by the

XmIconGadget

. As the table suggests, some traits are held by many of the standard Motif widgets.

Trait Installation in Standard Widget Set

widget holds both the

XmQTactivatable

and

XmQTcareParentVisual

traits.

The following table summarizes how the standard Motif widgets access traits. There are two general ways for a widget to access the traits of another widget.

One way is for a widget to ask another widget if it holds a particular trait. For example, XmBulletinBoard

asks each of its children widgets if they hold the

XmQTtakesDefault

trait.

XmBulletinBoard

calls none of the trait methods of

XmQTtakesDefault

Another kind of access is when one widget calls another widget's trait method(s). For example, XmBulletinBoard

calls the

getRenderTable

trait method of the

XmQTspecifyRenderTable

trait.
