XtQueryGeometry(Xt) X Version 11 (Release 5) XtQueryGeometry(Xt)
6 January 1993
Name
XtQueryGeometry - query the preferred geometry of a child widget
Syntax
XtGeometryResult XtQueryGeometry(w, intended, preferred_return)
Widget w;
XtWidgetGeometry *intended, *preferred_return;
Arguments
intended Specifies any changes the parent plans to make to the child's
geometry or NULL.
preferredreturn
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 corre-
sponding fields of the intended structure, sets the corresponding bits in
intended->request_mode, and calls XtQueryGeometry.
XtQueryGeometry clears all bits in the preferredreturn -> 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.
