Command executed when this control is resized. If you are dragging a window edge or splitter, the command won’t run until you finish.
No command will be sent in response to size or splitter changes made by winset().
If you include [[*]] in the command, it will be replaced by the control’s new size. Likewise, [[width]] will be replaced with the width and [[height]] with the height. (See embedded winget for more details on the [[...]] format.)
