XtMakeGeometryRequest(3Xt)           SysV           XtMakeGeometryRequest(3Xt)



NAME
     XtMakeGeometryRequest, XtMakeResizeRequest - make geometry manager
     request

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

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