You're right. I could not get the get_screen_size function to work (IDL
5.1), but extracting the relevant parts worked fine:

base = widget_base(display='redback:0', map=0)
draw = widget_draw(base, xsize=10, ysize=10, graphics_level=2)
widget_control, base, /realize
widget_control, draw, get_value=owindow
owindow->getproperty, screen_dimensions=dims
print, dims
      1024.00      768.000
obj_destroy, owindow
widget_control, base, /destroy

Cheers,
Liam.
