WIDGET_CONTROL is not a guaranteed way of changing the size of a widget.
Under X it sends a resize event and the widget attempts to change its
size. This is only a *request* to the X window manager - the window
manager does not have to honour it. If you try it using IRIX 5.2
and IDL 4.0 you will find that it doesn't work - what it does is to resize
the vertical size to 0.

The method I use is to destroy the old draw widget and create a new
one of the correct size.
