So far I can follow you. As said before, this can be done by deriving a class and using handle(int event) to change the backgroung picture as needed. > So I need to remove the focus from the widget which has focus. I still don't understand *this*. Removing the focus from a widget is handled automatically if another widget gets the focus. Do you mean that you need this for testing? Then, simply add another widget like an Fl_Input and click on this one, so the focus will move... Or, if you really need it in your program (why?), you can do Fl::focus(0), but I wouldn't know why you should need this. Still puzzled... Or do you only want to *know* when the widget *loses* the focus? Then you can use handle(int event) to handle the FL_UNFOCUS event. I believe I wrote this already, though.
