Recent?

It's not just that, but you don't want to process input while the
cursor is that font.  further, you don't want anything that may
have happened (mouse buttons or keyboard events) while the cursor
was changed to sudedenly "take action" when you are done.

I've found that the easiest thing to do (so far) is to create a
single InputOnly window (you can use XCreateWindow() for this) that
goes over the entire screen (DefaultWidget() and DefaultHeight())
(don't forget to call XMapWindow()) and call XtGrabPointer() setting
the _cursor_ parameter accordingly.  When you're done, ungrab the
pointer, unmap the input-only window and you should be done.  You
never change your cursor using this method -- you just add a new
window that has the cursor you want.*

Note; you have to do some XtAppProcessEvent() calls to make sure
that your window is mapped, or nothing will happen :-(.

It would sure be nice if one could communciate with mwm to do this
for you.
