Oh, I thin I understand. You can only have a single modal window. You
are trying to have two windows that are modal to the application at
the same tim.
Modal windows are actually just a shortcut for not disabling all
other windows. So what you can do is get the list of all windows that
are open in your application and call "disable()" on them, except
your two modal windows of course. You can get a list of windows n
your app using
for (win = Fl::first_window(); win; win = Fl::next_window(win)) {
...
}
There is one drawback though: all widgets in the other windows will
be grayed out. If you don't want that, you can write a new "Window"
class that can set a flag to ignore all mouse messages.
