In a large widget project I'm working on, there's a case when the
highest level widget event handler calls a smaller widget subroutine.
I need this subroutine to be blocking so that the main widget is forced
to wait until the subroutine widget is destroyed (either through a
cancel or an accept), but my attempts at setting no_block=0 in the call
to xmanager have not worked. What might I be doing wrong, and are
there any work-arounds?
Cheers
