XtQueryGeometry(3)			   XT FUNCTIONS 		       XtQueryGeometry(3)

NAME
       XtQueryGeometry - query the preferred geometry of a child widget

SYNTAX
       XtGeometryResult XtQueryGeometry(Widget w, XtWidgetGeometry *intended, XtWidgetGeometry
	      *preferred_return);

ARGUMENTS
       intended  Specifies any changes the parent plans to make to the child's geometry or NULL.

       preferred_return
		 Returns the child widget's preferred geometry.

       w	 Specifies the widget.

DESCRIPTION
       To discover a child's preferred geometry, the child's parent sets any changes that it
       intends to make to the child's geometry in the corresponding fields of the intended struc-
       ture, sets the corresponding bits in intended.request_mode, and calls XtQueryGeometry.

       XtQueryGeometry clears all bits in the preferred_return->request_mode and checks the
       query_geometry field of the specified widget's class record.  If query_geometry is not
       NULL, XtQueryGeometry calls the query_geometry procedure and passes as arguments the spec-
       ified widget, intended, and preferred_return structures.  If the intended argument is
       NULL, XtQueryGeometry replaces it with a pointer to an XtWidgetGeometry structure with
       request_mode=0 before calling query_geometry.
