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
getRenderTable
trait method of the XmQTspecifyRenderTable
trait.
