NAME

       XtRealizeWidget, XtIsRealized, XtUnrealizeWidget - realize and unrealize widgets

SYNOPSIS

       void XtRealizeWidget(w)
	       Widget w;

       Boolean XtIsRealized(w)
	       Widget w;

       void XtUnrealizeWidget(w)
	       Widget w;

ARGUMENTS

       Specifies the widget.

DESCRIPTION

       If the widget is already realized, XtRealizeWidget simply returns. Otherwise, it performs the following: Binds all action names in the wid-
       get's translation table to procedures (see Section 10.1.2).  Makes a post-order traversal of the widget tree rooted at the specified widget
       and  calls the change_managed procedure of each composite widget that has one or more managed children.	Constructs an XSetWindowAttributes
       structure filled in with information derived from the Core widget fields and calls the realize procedure for the  widget,  which  adds  any
       widget-specific	attributes  and  creates  the X window.  If the widget is not a subclass of compositeWidgetClass, XtRealizeWidget returns;
       otherwise, it continues and performs the following: Descends recursively to each of the widget's managed children  and  calls  the  realize
       procedures.  Primitive  widgets that instantiate children are responsible for realizing those children themselves.  Maps all of the managed
       children windows that have mapped_when_managed True. (If a widget is managed but mapped_when_managed is False, the widget is allocated vis-
       ual space but is not displayed.	Some people seem to like this to indicate certain states.)

       If  the	widget	is  a top-level shell widget (that is, it has no parent), and mapped_when_managed is True, XtRealizeWidget maps the widget
       window.

       The XtIsRealized function returns True if the widget has been realized, that is, if the widget has a nonzero X window ID.

       Some widget procedures (for example, set_values) might wish to operate differently after the widget has been realized.

       The XtUnrealizeWidget function destroys the windows of an existing widget and all of its children (recursively down the	widget	tree).	To
       recreate  the windows at a later time, call XtRealizeWidget again. If the widget was managed, it will be unmanaged automatically before its
       window is freed.
