But this problem seems not to be explicitly mentioned. I started to write something without reference other materials right after I learned the basic idea of customizing a widget. The cheat page and video tutorials are very useful and interesting. I finally understood the problem from examples on the cheat page. Thank you!
However, most write-your-own-widget examples put the widget in (0,0) of the top window, making it difficult to notice this problem (using 0,0 is the same as x(), y()). Explicitly pointing this out may be more helpful to newcomers of fltk. _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
