-.SH DESCRIPTION
-The
-.ZN XtCreateWidget
-function performs much of the boilerplate operations of widget creation:
-.IP \(bu 5
-Checks to see if the class_initialize procedure has been called for this class
-and for all superclasses and, if not, calls those necessary in a
-superclass-to-subclass order.
-.IP \(bu 5
-Allocates memory for the widget instance.
-.IP \(bu 5
-If the parent is a subclass of
-.ZN constraintWidgetClass ,
-it allocates memory for the parent's constraints
-and stores the address of this memory into the constraints field.
-.IP \(bu 5
-Initializes the core nonresource data fields
-(for example, parent and visible).
-.IP \(bu 5
-Initializes the resource fields (for example, background_pixel)
-by using the resource lists specified for this class and all superclasses.
-.IP \(bu 5
-If the parent is a subclass of
-.ZN constraintWidgetClass ,
-it initializes the resource fields of the constraints record
-by using the constraint resource list specified for the parent's class
-and all superclasses up to
-.ZN constraintWidgetClass .
-.IP \(bu 5
-Calls the initialize procedures for the widget by starting at the
-.ZN Core
-initialize procedure on down to the widget's initialize procedure.
-.IP \(bu 5
-If the parent is a subclass of
-.ZN compositeWidgetClass ,
-it puts the widget into its parent's children list by calling its parent's
-insert_child procedure.
-For further information,
-see Section 3.5.
-.IP \(bu 5
-If the parent is a subclass of
-.ZN constraintWidgetClass ,
-it calls the constraint initialize procedures,
-starting at
-.ZN constraintWidgetClass
-on down to the parent's constraint initialize procedure.
-.LP
-Note that you can determine the number of arguments in an argument list
-by using the
-.ZN XtNumber
-macro.
-For further information, see Section 11.1.
-.LP
-The
-.ZN XtCreateManagedWidget
-function is a convenience routine that calls
-.ZN XtCreateWidget
-and
-.ZN XtManageChild .
-.LP
-The
-.ZN XtDestroyWidget
-function provides the only method of destroying a widget,
-including widgets that need to destroy themselves.
-It can be called at any time,
-including from an application callback routine of the widget being destroyed.
-This requires a two-phase destroy process in order to avoid dangling
-references to destroyed widgets.
-.LP
-In phase one,
-.ZN XtDestroyWidget
-performs the following:
-.IP \(bu 5
-If the being_destroyed field of the widget is
-.ZN True ,
-it returns immediately.
-.IP \(bu 5
-Recursively descends the widget tree and
-sets the being_destroyed field to
-.ZN True
-for the widget and all children.
-.IP \(bu 5
-Adds the widget to a list of widgets (the destroy list) that should be
-destroyed when it is safe to do so.
-.LP
-Entries on the destroy list satisfy the invariant that
-if w2 occurs after w1 on the destroy list then w2 is not a descendent of w1.
-(A descendant refers to both normal and pop-up children.)
-.LP
-Phase two occurs when all procedures that should execute as a result of
-the current event have been called (including all procedures registered with
-the event and translation managers),
-that is, when the current invocation of
-.ZN XtDispatchEvent
-is about to return or immediately if not in
-.ZN XtDispatchEvent .
-.LP
-In phase two,
-.ZN XtDestroyWidget
-performs the following on each entry in the destroy list:
-.IP \(bu 5
-Calls the destroy callback procedures registered on the widget
-(and all descendants) in post-order (it calls children callbacks
-before parent callbacks).
-.IP \(bu 5
-If the widget's parent is a subclass of
-.ZN compositeWidgetClass
-and if the parent is not being destroyed,
-it calls
-.ZN XtUnmanageChild
-on the widget and then calls the widget's parent's delete_child procedure
-(see Section 3.4).
-.IP \(bu 5
-If the widget's parent is a subclass of
-.ZN constraintWidgetClass ,
-it calls the constraint destroy procedure for the parent,
-then the parent's superclass,
-until finally it calls the constraint destroy procedure for
-.ZN constraintWidgetClass .
-.IP \(bu 5
-Calls the destroy methods for the widget (and all descendants)
-in post-order.
-For each such widget,
-it calls the destroy procedure declared in the widget class,
-then the destroy procedure declared in its superclass,
-until finally it calls the destroy procedure declared in the Core
-class record.
-.IP \(bu 5
-Calls
-.ZN XDestroyWindow
-if the widget is realized (that is, has an X window).
-The server recursively destroys all descendant windows.
-.IP \(bu 5
-Recursively descends the tree and deallocates all pop-up widgets, constraint
-records, callback lists and, if the widget is a subclass of
-.ZN compositeWidgetClass ,
-children.
