XtMakeResizeRequest() XtMakeResizeRequest()
Name
XtMakeResizeRequest - request parent to change child's size.
Synopsis
XtGeometryResult XtMakeResizeRequest(w, width, height, width_return, height_return)
Widget w;
Dimension width, height;
Dimension *width_return, *height_return
Inputs
w Specifies the child widget making the request.
width, height
Specify the desired widget width and height.
Outputs
width_return, height_return
Return a compromise size when the function returns XtGeometryAlmost. May be NULL if the widget is not interested in compro-
mises.
Returns
A response to the request: XtGeometryYes, XtGeometryNo or XtGeometryAlmost.
Description
XtMakeResizeRequest() is a simplified version of XtMakeGeometryRequest() that a child can use to ask its parent to change its size. It
creates an XtWidgetGeometry structure, specifies width, and height, sets request_mode to (CWWidth CWHeight), and passes it to XtMakeGeome-
tryRequest(). Note that the geometry manager is free to modify any of the other window attributes (position or stacking order) to satisfy
the resize request.
The return values are as for XtMakeGeometryRequest(). 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 another XtMakeResizeRequest() and request that
the compromise width and height be applied.
See XtMakeGeometryRequest() for more information.
Usage
XtMakeResizeRequest() should only be used in widget code by widgets which would like to change their own size. Applications that want to
set a widget size should use XtSetValues() on the XtNwidth and XtNheight resources of the widget. A widget that wants to change the size
of one of its children should use XtResizeWidget().
