XtMakeGeometryRequest(3Xt)             XtMakeGeometryRequest(3Xt)



NAME
     XtMakeGeometryRequest, XtMakeResizeRequest -  make  geometry
     manager requests

SYNOPSIS
     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

DESCRIPTION
     Depending on the condition, XtMakeGeometryRequest performs
     these operations:

          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 member is TRUE, it re-
          turns XtGeometryNo.

          If the widget x, y, width, height and border_width
          members are all equal to the requested values, it re-
          turns 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
          member of the XtWidgetGeometry structure 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 the 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 im-
     mediately 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.

   Arguments
     These functions accept the following 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, posi-
             tion, 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.
