XtQueryGeometry(3Xt)      XT FUNCTIONS       XtQueryGeometry(3Xt)

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 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 cal-
     ling query_geometry.
