]]>]]>DtMenuButton library callDtMenuButtonthe MenuButton widget class #include <Dt/MenuButton.h> The DtMenuButton widget is a command widget that complements the menu cascading functionality of an XmCascadeButton widget. As a complement to the XmCascadeButton widget, DtMenuButton can only be instantiated outside a MenuPane; the application must use XmCascadeButton widget inside a MenuPane. The DtMenuButton widget belongs to a subclass of the XmLabel class. Visually, the DtMenuButton widget consists of a label string and a menu glyph. The menu glyph always appears on the right end of the widget and, by default, is a downward pointing arrow. The DtMenuButton widget has an implicitly created submenu attached to it. The submenu is a popup MenuPane and has this DtMenuButton widget as its parent. The name of the implicitly created submenu is obtained by adding submenu_ as a prefix to the name of this DtMenuButton widget. The widget ID of the submenu can be obtained by doing an XtGetValues on the DtNsubMenuId resource of this DtMenuButton widget. The implicitly created submenu must not be destroyed by the user of this widget. The submenu can be popped up by pressing the menu post Button (see the XmNmenuPost resource of the anywhere on the DtMenuButton widget. Widget subclassing is not supported for the DtMenuButton widget class. The DtMenuButton widget inherits behavior and resources from the Core, Composite, XmPrimitive and XmLabel classes. The class pointer is dtMenuButtonWidgetClass. The class name is DtMenuButtonWidget. The following table defines a set of widget resources used by the application to specify data. The application can also set the resource values for the inherited classes to set attributes for this widget. To reference a resource by name or by class in a .Xdefaults file, the application must remove the DtN or DtC prefix and use the remaining letters. To specify one of the defined values for a resource in a .Xdefaults file, the application must remove the Dt prefix and use the remaining letters (in either lower case or upper case, but including any underscores between words). The codes in the access column indicate if the given resource can be set at creation time (C), set by using XtSetValues (S), retrieved by using XtGetValues (G), or is not applicable (N/A). DtMenuButton Resource Set Name Class Type Default Access DtNcascadingCallback DtCCallback XtCallbackList NULL C DtNcascadePixmap DtCPixmap Pixmap XmUNSPECIFIED_PIXMAP CSG DtNsubMenuId DtCMenuWidget Widget NULL SG DtNcascadingCallback Specifies the list of callbacks that is called before the popping up of the attached submenu. The reason for the callback is DtCR_CASCADING. DtNcascadePixmap Specifies the pixmap displayed as the menu glyph. If no pixmap is specified, a downward pointing arrow is displayed. DtNsubMenuId Specifies the widget ID of the popup MenuPane to be associated with this DtMenuButton widget. The popup MenuPane must be created with this DtMenuButton as its parent. This resource cannot be specified at the time of widget creation. The implicit submenu is automatically destroyed by DtMenuButton when this resource is set. The DtMenuButton widget inherits behavior and resources from the following named superclasses. For a complete description of each resource, see the for that superclass.
