How to alter a PNG icon in Qt -


The effect that I wanted to achieve is like a mail icon in some iPhone, a rounded rectangle at the top corner of the mail icon The number inside the rectangle reflects the current number of unread emails and can change dynamically when new emails arrive. I am thinking that it is possible to use QT 4.6 for the desktop application interface. If this is possible, how should I learn classes? (I think there should be some bitmap manipulation class in QT.) Thanks.

But I do not think the code is capable of changing the color of each variable declared....
