Traits man page

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 NameA Widget Holding This Trait Can Do The Following:


XmQTaccessTextualDisplay one primary text parcel.


XmQTactivatableBecome a command button in a dialog box.


XmQTcareParentVisualBorrow its parent's visual information.


XmQTcontainerManage container item children.


XmQTcontainerItemBecome a child of a container widget.


XmQTdialogShellSavvyBecome a child of a DialogShell.


XmQTjoinSideAttach itself to one side of a suitable parent.


XmQTmenuSavvyBecome a menu child.


XmQTmenuSystemManage a menu system.


XmQTnavigatorAct as a navigator to a scrollable widget.


XmQTscrollFrameHandle one or more navigator widgets.


XmQTspecifyRenderTableSupply the names of its default render tables.


XmQTtakesDefaultChange its appearance to show that it is the default button.


XmQTtransferTransfer 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 getRenderTable trait method of the XmQTspecifyRenderTable trait.
