NAME

       XtMakeGeometryRequest, XtMakeResizeRequest - make geometry manager request

SYNTAX

       XtGeometryResult XtMakeGeometryRequest(Widget w, XtWidgetGeometry *request, XtWidgetGeometry
              *reply_return);

       XtGeometryResult XtMakeResizeRequest(Widget w, Dimension width, height, Dimension *width_return,
              Dimension *height_return);

ARGUMENTS

       reply_return
                 Returns the allowed widget size or may be NULL if the requesting widget is not interested in
                 handling XtGeometryAlmost.

       request   Specifies the desired widget geometry (size, position, border width, and stacking order).

       w         Specifies the widget that is making the request.

       width_return
       height_return
                 Return the allowed widget width and height.

DESCRIPTION

       Depending on the condition, XtMakeGeometryRequest performs the following:

       •    If the widget is unmanaged or the widget's parent is not realized, it makes the changes and returns
            XtGeometryYes.

       •    If the parent is not a subclass of compositeWidgetClass or the parent's geometry_manager is NULL, it
            issues an error.

       •    If the widget's being_destroyed field is True, it returns XtGeometryNo.

       •    If the widget x, y, width, height and border_width fields are all equal to the requested values, it
            returns XtGeometryYes; otherwise, it calls the parent's geometry_manager procedure with the given
            parameters.

       •    If the parent's geometry manager returns XtGeometryYes and if XtCWQueryOnly is not set in the
            request_mode and if the widget is realized, XtMakeGeometryRequest calls the XConfigureWindow Xlib
            function to reconfigure the widget's window (set its size, location, and stacking order as
            appropriate).

       •    If the geometry manager returns XtGeometryDone, the change has been approved and actually has been
            done.  In this case, XtMakeGeometryRequest does no configuring and returns XtGeometryYes.
            XtMakeGeometryRequest never returns XtGeometryDone.

       Otherwise, XtMakeGeometryRequest returns the resulting value from the parent's geometry manager.

       Children of primitive widgets are always unmanaged; thus, XtMakeGeometryRequest always returns
       XtGeometryYes when called by a child of a primitive widget.

       The XtMakeResizeRequest function, a simple interface to XtMakeGeometryRequest, creates a XtWidgetGeometry
       structure and specifies that width and height should change.  The geometry manager is free to modify any
       of the other window attributes (position or stacking order) to satisfy the resize request.  If the return
       value is XtGeometryAlmost, width_return and height_return contain a compromise width and height.  If
       these are acceptable, the widget should immediately make an XtMakeResizeRequest and request that the
       compromise width and height be applied.  If the widget is not interested in XtGeometryAlmost replies, it
       can pass NULL for width_return and height_return.
