Specifies any changes the parent plans to make to the child's geometry or NULL.
Returns the child widget's preferred geometry.
Specifies the widget.
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 specified 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.
