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. Trait Installation in Standard Widget Set Trait Name Is Installed on The Following Widgets: XmQTaccessTextual XmLabel and all its subclasses; XmLabelGadgetand all its subclasses; XmText; XmTextField XmQTactivatable XmArrowButton; XmArrowButtonGadget; XmDrawnButton; XmPushButton; XmPushButtonGadget XmQTcareParentVisual All the subclasses of XmGadget (but not XmGadget itself); XmPrimitive and all its subclasses XmQTcontainer XmContainer XmQTcontainerItem XmIconGadget XmQTdialogShellSavvy XmBulletinBoard XmQTjoinSide No widgets install this trait XmQTmenuSavvy XmLabel; XmDrawnButton; XmCascadeButton; XmPushButton; XmToggleButton; XmLabelGadget; XmCascadeButtonGadget; XmPushButtonGadget; XmToggleButtonGadget XmQTmenuSystem XmRowColumn XmQTnavigator XmScrollBar; XmSpinBox XmQTscrollFrame XmNotebook; XmScrolledWindow XmQTspecifyRenderTable XmBulletinBoard and all its subclasses; XmMenuShell; XmVendorShell XmQTtakesDefault XmPushButton; XmPushButtonGadget XmQTtransfer XmContainer; XmLabel and all its subclasses; XmLabelGadget and all its subclasses; XmList; XmScale; XmText; XmTextField The following table lists the traits installed on each widget. For example, the following table indicates that the XmArrowButton widget holds both the XmQTactivatableand XmQTcareParentVisual traits. Trait Use by Widget Widget Name Installs These Traits = XmArrowButton XmQTactivatable, XmQTcareParentVisual XmArrowButtonGadget XmQTactivatable, XmQTcareParentVisual XmBulletinBoard XmQTdialogShellSavvy, XmQTspecifyRenderTable XmCascadeButton XmQTaccessTextual, XmQTcareParentVisual, XmQTmenuSavvy, XmQTtransfer XmCascadeButtonGadget XmQTaccessTextual, XmQTcareParentVisual, XmQTmenuSavvy, XmQTtransfer XmComboBox XmCommand XmQTspecifyRenderTable XmContainer XmQTcontainer, XmQTtransfer XmDialogShell None XmDisplay None XmDragContext None XmDragIcon None XmDrawingArea None XmDrawnButton XmQTaccessTextual, XmQTactivatable, XmQTcareParentVisual, XmQTmenuSavvy, XmQTtransfer XmDropTransfer None XmFileSelectionBox XmQTspecifyRenderTable XmForm XmQTspecifyRenderTable XmFrame None XmGadget None XmIconGadget XmQTcareParentVisual, XmQTcontainerItem XmLabel XmQTaccessTextual, XmQTcareParentVisual, XmQTmenuSavvy, XmQTtransfer XmLabelGadget XmQTaccessTextual, XmQTcareParentVisual, XmQTmenuSavvy, XmQTtransfer XmList XmQTcareParentVisual, XmQTtransfer XmMainWindow XmManager XmMenuShell XmQTspecifyRenderTable XmMessageBox XmQTspecifyRenderTable XmNotebook XmQTscrollFrame XmPanedWindow XmPrimitive XmQTcareParentVisual XmPushButton XmQTaccessTextual, XmQTactivatable, XmQTcareParentVisual, XmQTmenuSavvy, XmQTtakesDefault, XmQTtransfer XmPushButtonGadget XmQTaccessTextual, XmQTactivatable, XmQTcareParentVisual, XmQTmenuSavvy, XmQTtakesDefault, XmQTtransfer XmRowColumn XmQTmenuSystem XmScale XmQTtransfer XmScreen XmScrollbar XmQTcareParentVisual, XmQTnavigator XmScrolledWindow XmQTscrollFrame XmSelectionBox XmQTspecifyRenderTable XmSeparator XmQTcareParentVisual XmSeparatorGadget XmQTcareParentVisual XmSpinBox XmQTnavigator XmText XmQTaccessTextual, XmQTcareParentVisual, XmQTtransfer XmTextField XmQTaccessTextual, XmQTcareParentVisual, XmQTtransfer XmToggleButton XmQTaccessTextual, XmQTcareParentVisual, XmQTtransfer XmToggleButtonGadget XmQTaccessTextual, XmQTcareParentVisual, XmQTtransfer 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 getRenderTabletrait method of the XmQTspecifyRenderTabletrait.
