Re: blocking operation

[Darin Fisher <dfisher jagger me berkeley edu>]

gtk_window_set_modal() is only part of the solution.  You need to use it in
conjunction with gtk_main() to block the calling thread.  The source for
GnomeDialog shows how this is done.  Unfortunately, I don't know how to
insert a GtkFileSelection dialog into a GnomeDialog.  So, you probably have
to roll your own, or ...

I have implemented a blocking modal file dialog for a project I am working
on (http://gnofin.sourceforge.net).  If you're interested, you can find it under

gnofin/src/dialogs/dialog-file.c.  It is fairly self-contained.

Hope this helps,
Darin
