I don't know. Did you try this and find it *doesn't*
work for object graphics windows? I've always managed
to change the requirements document for things like
this. ;-)

Cheers,

Thanks. What if I have an object graphics draw widget (graphics_level
= 2)? Do I have to resort to some hack like placing a direct graphics
window behind it? (Don't think that will work for my application.)

Try TVCRS after making the draw widget the current graphics window.

Yeah, TVCRS won't work for object graphics windows. One hack is to
use a 1x1 WIDGET_BASE containing 1x1 WIDGET_DRAW, realized on top of
the object graphics window offset to where you want the cursor to be,
then TVCRS the cursor onto that tiny window before destroying it (and
possibly re-setting focus). It works well, actually. JC
