+  You may want to handle FL_WHEN_CHANGED events for tracking text changes
+  and also FL_WHEN_RELEASE for button release when changing to parent dir.
+  FL_WHEN_RELEASE callback won't be called if the directory clicked 
+  is the same that the current one.

+  \note As all Fl_Input derived objects, Fl_File_Input may call its callback
+  when loosing focus (see FL_UNFOCUS) to update its state like its cursor shape.
+  One resulting side effect is that you should call clear_changed() early in your callback
+  to avoid reentrant calls if you plan to show another window or dialog box in the callback.
