[Gambas-user] Control.Grab (gb.qt4) - The old way?

[Bruce]

Like the fine help says, back in the olden days Control.Grab used to 
take a scrren shot of the control but that's gone away. Fine. But 
weirdly enough I now find that I want to get an image or picture of a 
control (or wondow) but primarily a specific control.

So, is there a way to so that now?
Failing that, would anyone have the code of how it was done in Gambas2 
or any ideas of how it could be done?
