hi
I'm in full support of your effort. Just a small comment:
int main(int argc, char* argv[]) { window w = create_window(); w->title("Example window");
why is window implicitly a pointer?
In fact, window is defined thus:
typedef boost::shared_ptr<window_base> window;
The reason is that widgets are always reference-counted. The alternative would have been to make window a pimpl class, with the impl being reference counted. However, since I wanted to use the factory pattern to firewall the implementation of widgets, I would have to have my widgets on the heap anyway, so I just made widget a shared pointer to the WDT (whole damn thing).
Does that make sense? :-)
yeah its ok, I was thinking that seing window and not window* could confuse some.
Adn maybe
9. It should be possible to create worm-like games in it, where student need to draw the worm by moving pixels or something around :-)
Ha ha, yes.
Just to be sure, I'm not kidding. I assume a C++ gui lib should be possible to use to learn C++. Writing small games by moving pixels around is a great way to practice, much more fun than making a menu or pop-up box. br Thorsten
