Composite --The Composite widget class
As shipped in IRIX 6.5.5. Unchanged since IRIX 6.5.
NAME Composite --The Composite widget class SYNOPSIS #include <Xm/Xm.h> VERSION This page documents version 1.2 of the Motif library. DESCRIPTION Composite widgets are intended to be containers for other widgets and can have an arbitrary number of children. Their responsibilities (implemented either directly by the widget class or indirectly by Intrinsics functions) include: * Overall management of children from creation to destruction. * Destruction of descendants when the composite widget is destroyed. * Physical arrangement (geometry management) of a displayable subset of managed children. * Mapping and unmapping of a subset of the managed children. Instances of composite widgets need to specify the order in which their children are kept. For example, an application may want a set of command but- tons in some logical order grouped by function, and it may want but- tons that represent filenames to be kept in alphabetical order. Classes Composite inherits behavior and resources from Core. The class pointer is compositeWidgetClass. The class name is Composite. New Resources The following table defines a set of widget resources used by the program- mer to specify data. The programmer 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, remove the XmN or XmC prefix and use the remaining letters. To specify one of the defined values for a resource in a .Xdefaults file, remove the Xm prefix and use the re- maining letters (in either lowercase or uppercase, but include any under- scores 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). Composite Resource Set Name Class Type Default Access ----------------------------------------------------------------------- XmNchildren XmCReadOnly WidgetList NULL G XmNinsertPosition XmCInsertPosition XtOrderProc NULL CSG XmNnumChildren XmCReadOnly Cardinal 0 G XmNchildren A read-only list of the children of the widget. XmNinsertPosition Points to the XtOrderProc function described below. XmNnumChildren A read-only resource specifying the length of the list of chil- dren in XmNchildren. The following procedure pointer in a composite widget instance is of type XtOrderProc: Cardinal (* XtOrderProc) (widget) Widget w; w Specifies the widget. Composite widgets that allow clients to order their children (usually homo- geneous boxes) can call their widget instance's insert_position procedure from the class's insert_child procedure to determine where a new child should go in its children array. Thus, a client of a composite class can apply different sorting criteria to widget instances of the class, passing in a different insert_position procedure when it creates each composite widget instance. The return value of the insert_position procedure indicates how many chil- dren should go before the widget. Returning zero indicates that the widget should go before all other children; returning num_children indicates that it should go after all other children. The default insert_position func- tion returns num_children and can be overridden by a specific composite widget's resource list or by the argument list provided when the composite widget is created. Inherited Resources Composite inherits behavior and resources from the following superclass. For a complete description of each resource, refer to the manual page for that superclass.
