XtMakeGeometryRequest(3) XT FUNCTIONS XtMakeGeometryRequest(3) NAME XtMakeGeometryRequest, XtMakeResizeRequest - make geometry manager request SYNTAX #include <X11/Intrinsic.h> XtGeometryResult XtMakeGeometryRequest(Widget w, XtWidgetGeometry *request, XtWidgetGeometry *reply_return); XtGeometryResult XtMakeResizeRequest(Widget w, Dimension width, Dimension 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 par- ent's geometry_manager is NULL, it issues an error. * If the widget's being_destroyed field is True, it returns XtGeome- tryNo. * 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 parame- ters. * If the parent's geometry manager returns XtGeometryYes and if XtCW- QueryOnly is not set in the request_mode and if the widget is real- ized, XtMakeGeometryRequest calls the XConfigureWindow Xlib function to reconfigure the widget's window (set its size, location, and stack- ing order as appropriate). * If the geometry manager returns XtGeometryDone, the change has been approved and actually has been done. In this case, XtMakeGeometry- Request does no configuring and returns XtGeometryYes. XtMake- GeometryRequest never returns XtGeometryDone. Otherwise, XtMakeGeometryRequest returns the resulting value from the par- ent's geometry manager. Children of primitive widgets are always unmanaged; thus, XtMakeGeometry- Request always returns XtGeometryYes when called by a child of a primitive widget. The XtMakeResizeRequest function, a simple interface to XtMakeGeometry- Request, 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 accept- able, the widget should immediately make an XtMakeResizeRequest and request that the compromise width and height be applied. If the widget is not in- terested in XtGeometryAlmost replies, it can pass NULL for width_return and height_return.
