XtQueryGeometry(3Xt) XtQueryGeometry(3Xt)
NAME
XtQueryGeometry - query the preferred geometry of a
child widget
SYNOPSIS
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.
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 structure, 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 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.
