Version: 1.3.2
Attaching a test program, when.cxx, to test the when() behavior
of tabs vs. radio buttons vs. hold + multi browser.
Also, used this program to generate this table of when() behavior
which will be useful for perhaps fixing not only Fl_Tabs, but bugs
in existing widgets:
http://seriss.com/people/erco/fltk/when-behavior-03-26-2013.html
This test should probably be integrated into the unittests
to check the when() behavior of all widgets. (Instead of using
the tty, the unittest could probably pop open an Fl_Text_Display
widget on first callback, and scroll realtime callback msgs in that)
