NAME
Traits - Lists the traits used by the Motif Toolkit.
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.

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 getRenderTabletrait method of the
XmQTspecifyRenderTabletrait.
