XtQueryGeometry
NAME
XtQueryGeometry - query the preferred geometry of a child
widget
SYNTAX
XtGeometryResult XtQueryGeometry(w, intended, pre-
ferred_return)
Widget w;
XtWidgetGeometry *intended, *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 par-
ent sets any changes that it intends to make to the
child's geometry in the corresponding fields of the
intended structure, sets the corresponding bits in
intended.request_mode, and calls XtQueryGeometry.
XtQueryGeometry clears all bits in the pre-
ferred_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.
