Traits(5) File Formats Manual Traits(5) 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 follow- ing 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 di- | | | alog box. | +------------------------+----------------------------------+ | XmQTcareParentVisual | Borrow its parent's visual in- | | | formation. | +------------------------+----------------------------------+ | 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 scrol- | | | lable 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 | | Trait Name | Is Installed on The Following | | | Widgets: | +------------------------+----------------------------------+ | XmQTaccessTextual | XmLabel and all its subclasses; | | | XmLabelGadget and all its sub- | | | classes; XmText; XmTextField | +------------------------+----------------------------------+ | XmQTactivatable | XmArrowButton; XmArrowButtonGad- | | | get; XmDrawnButton; XmPushBut- | | | ton; XmPushButtonGadget | +------------------------+----------------------------------+ | XmQTcareParentVisual | All the subclasses of XmGadget | | | (but not XmGadget itself); Xm- | | | Primitive and all its subclasses | +------------------------+----------------------------------+ | XmQTcontainer | XmContainer | +------------------------+----------------------------------+ | XmQTcontainerItem | XmIconGadget | +------------------------+----------------------------------+ | XmQTdialogShellSavvy | XmBulletinBoard | +------------------------+----------------------------------+ | XmQTjoinSide | No widgets install this trait | +------------------------+----------------------------------+ | XmQTmenuSavvy | XmLabel; XmDrawnButton; XmCas- | | | cadeButton; XmPushButton; XmTog- | | | gleButton; XmLabelGadget; XmCas- | | | cadeButtonGadget; XmPushButton- | | | Gadget; XmToggleButtonGadget | +------------------------+----------------------------------+ | XmQTmenuSystem | XmRowColumn | +------------------------+----------------------------------+ | XmQTnavigator | XmScrollBar; XmSpinBox | +------------------------+----------------------------------+ | XmQTscrollFrame | XmNotebook; XmScrolledWindow | +------------------------+----------------------------------+ | XmQTspecifyRenderTable | XmBulletinBoard and all its sub- | | | classes; XmMenuShell; XmVendor- | | | Shell | +------------------------+----------------------------------+ | XmQTtakesDefault | XmPushButton; XmPushButtonGadget | +------------------------+----------------------------------+ | XmQTtransfer | XmContainer; XmLabel and all its | | | subclasses; XmLabelGadget and | | | all its subclasses; XmList; Xm- | | | Scale; XmText; XmTextField | +------------------------+----------------------------------+ +------------------------+----------------------------------+ The following table lists the traits installed on each widget. For ex- ample, the following table indicates that the XmArrowButton widget holds both the XmQTactivatable and XmQTcareParentVisual traits.

+-----------------------+-------------------------------------+ | VendorShell | XmQTspecifyRenderTable | +-----------------------+-------------------------------------+ +-----------------------+-------------------------------------+ 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. +--------------------------------------------------------------------------------------+ | |
