The +inner window can contain all the data that is to be displayed. This inner +window will be clipped by the frame with the scrollbars controlling +which section of the inner window is currently visible. + + + + + + + + +The geometry management semantics provided by the X Toolkit give full +control of the size and position of a widget to the parent of that +widget. While the children are allowed to request a certain size or +location, it is the parent who makes the final decision. Many of the +composite widgets here will deny any geometry request from their +children by default. If a child widget is not getting the expected size +or location, it is most likely the parent disallowing a request, or +implementing semantics slightly different than those expected by the +application programmer. + + + +If the application wishes to change the size or location of +any widget it should make a call to XtSetValues. This will + +allow the widget to ask its parent for the new size or location. +As noted above the parent is allowed to refuse this request, +and the child must live with the result. If the +application is unable to achieve the desired semantics, then perhaps it +should use a different composite widget. Under no circumstances +should an application programmer resort to XtMoveWidget or + +XtResizeWidget; these functions are exclusively for the use of + +Composite widget implementors. + + + +For more information on geometry management consult the X Toolkit Intrinsics - C Language Interface. + + + + + + + + + + + + -- cgit v1.2.3
