XT FUNCTIONS                           XtMakeGeometryRequest(3xt)



NAME
     XtMakeGeometryRequest, XtMakeResizeRequest - make geometry
     manager request

SYNTAX
     cc [ flag... ] file... -lXt [ library... ]

     XtGeometryResult XtMakeGeometryRequest(Widget w, XtWidget-
          Geometry *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 han-
               dling 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.

DESCRIPTION
     Depending on the condition, XtMakeGeometryRequest performs
     the following:

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

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

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

     +o    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.

     +o    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

XT FUNCTIONS                           XtMakeGeometryRequest(3xt)



          the XConfigureWindow Xlib function to reconfigure the
          widget's window (set its size, location, and stacking
          order as appropriate).

     +o    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.
