It's not the entire program - where's main() ?  ;-)

Have you checked (printed) that i and j are values that you expect
(ie. within the label's qrect)?

Have you checked that label->rect() is a QRect that you expect?

Maybe write a unit test so that you know what the code is doing.

Hope that helps,
