Resizable overview 'rectangle'

Hi,
In Demo1 sample, I can click on View->Overview and zoom or move to any part of the current view by dragging or moving a “rectangle”. If I want to select a larger portion of the view then I need to draw a new larger rectangle.
Is there a way to allow this overview rectangle to be resizable. I mean, just like for nodes, is there a way to show resize handles around the overview rectangle, so as to make this rectangle resizable.

Thanks,
Rafique

The implementation of GoOverview and GoOverviewRectangle don’t support that functionality at the moment. I suppose you could implement that yourself, although it’s probably trickier than it might appear at first.
If you want to do this yourself, send me e-mail and maybe I can help.
