Hi, I have an access violation problem in my project, I made a small example for demonstration: http://paste-bin.com/view/38d8960c
So there's class A, subclassed from Fl_Group, it has a button, thats callback is using a virtual function, wich is implemented in class B (subclassed from class A). The program compiles fine, but when you use the button, it drops an Access Violation (same happens if I use Fl_Scroll instead of Fl_Group, if I subclass A from a container I get this error I guess). In this second case, I changed the base of the A class, so it is now subclassed from Fl_Button, and with the same callback everything wokrs fine, the program exits after button press. http://paste-bin.com/view/8d417487 This may be not an FLTK problem at all, my knowledge of classes have leaks, but I am really starving for help here! Thanks. _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
