In my tests, the FL_WHEN_ENTER_KEY part *does* work as expected, i.e. the
callback is called when I press ENTER. However, I can see that pressing
TAB to leave the input field doesn't call the callback. See attached
simple test case spinner.cxx.
I'm not convinced that adding FL_WHEN_CHANGED is the correct solution, but
I'm not sure about it. However, I believe that pressing TAB (or clicking on
another widget *should* trigger the callback, if FL_WHEN_RELEASE is set
(unfortunately my simple test case doesn't contain other widgets...).
