Hi,

Hopefully this won't turn out to be a dozy question - I'm a bit out of
practise on IDL at the moment.

Anyway, what I'd like to do is grab a window image, so that I can write it
out as a GIF.

The difficulty I'm having is that as I'm using widgets, I'm not sure how to
get the actual window ID for the
the call to TVRD(), all I seem to get back is the draw widget contents.

e.g.

pro get_window

base = widget_base(/column)
junk = widget_label(base,value = "Hi")
draw = widget_draw(base,xsize=200,ysize=300)
.
.
widget_control,base,/realize
widget_control,draw,get_value = draw_id

res = tvrd()
help,res
end

This just returns me an array of the draw widget (200x300), not the whole
window.

cheers,

Mark
