Hi,
I've recently taken to experimenting with this graphics library and have had
some success with it so far. I'm developing my own application with the limited
knowledge that I have of programming but consider myself an intermediate
programmer.
Anyways, I have this problem where I can't get this window to pop up when I
initiate the callback for it. I have written the situation that I am having
problems with and hopefully somebody out there can show me where I went wrong.
You can copy and paste this example into a text editor and compile and link it
yourself. The error is a run-time error, I just can't figure it out.
Thanks so much!
Kjell

Fl_Window* NuWin = new Fl_Window(50, 100, "Hooray!");
But->callback(Button_CB);
Win->end();
Win->show();
return Fl::run();
}

{

tWin->NuWin->show();
}
