Great, you'll have it working soon enough! Indeed, if you don't set the
_quit variable somewhere the loop never breaks. There are several options
there. Since it looks like you made _quit a global variable, you could
simply put _quit =3D 1 in the close() function of the dialog. Alternatively=
,
you could construct a quit event in the close() and send it. Then it'll
automatically get picked up by the event loop which will set _quit.
There are more complicated ways like periodically checking whether the
dialog is still opened, but this seems less efficient than just using the
close function options.

Jasper
