So this is the effect what I want to get. Left and right parts of a label should have different filling/stroke colors (actually stroke size is also changed). And the proportion may change dynamically, and can be some position inside a letter.

I know I should override the paintEvent but still have no idea of how to do it. Any ideas?

I actually don't know, but look at Qt Examples `Qml Video Shader Effect` – t3ft3l--i Jul 24 '15 at 06:40

I would not start from a QLabel but rather from a QProgressBar, the initial text as a background image and while the time goes on you paint on top of it the other image with the highlighted text. – Marco Jul 24 '15 at 06:54
