Ah man.... did you even try to compile this code?

At moments like this I'm beginning to think if we're even remotely close to managing to educate people here...

Maybe we should get some programming certification scheme here or something...

what i found is many ppl know c++ but do not know one of these concepts 1. inheritance 2. virtual 3. pointers. And they jump into Qt. This where all starts to mess up.

It's like "they know how to drive but only on the first gear and only straight ahead". It's hard to call it "knowing how to drive" then... But that you don't know how to program is not a big deal. It starts to be a deal when you're not learning and still continue to bang your head against the wall.

i have seen ppl make very good/fast newbiew programs in c++ ... but they seem to take ages to get into inheritance thing...

So was it c++ or c?

Ok, we're getting offtopic here.

ya.. just like to share one incident (which i remembered by reading this thread) if you permit..

...
once i was taking interview of a candidate who had 5+ years of programming exp in Qt. I asked, "If i inherit QPushButton and QCombobox in my class, how would the widget will look like?".

He replied: "If You inherit QPushButton first (like class w : public QPushbutton, QCombobox) then the widget will have the appearance of a button and vice versa".
REJECTED.

I thought then that he was a masterpiece and i will never find someone like him again. Guess i was wrong
