Yes, that's possible too! I just discovered it myself a couple of
days ago.
The TVCRS procedure can be used to move the mouse cursor anywhere,
even outside the (possibly unmapped) currently selected draw window.
The following example should demonstrate this:
base = widget_base(/row)
text = widget_text(base,xsize=100)
dummy= widget_base(base,map=0)
draw = widget_draw(dummy,xsize=1,ysize=1)
widget_control,base,/realize
widget_control,draw,get_value=window
wset,window
tvcrs,-200,-20,/device
widget_control,text,/input_focus
You just have to match the X,Y device coordinates to where you want the
mouse cursor to appear.
