Qt - Real time drawing

Question

I want to show a car's path in a window in real time, how to do that, and what classes I have to use. Is there anything like drawing area, in Qt.

Any Help will be appreciated.

Answer 1

You'll need to read up on QGraphicsview . There are several helpful examples that show every bit of what functionality is present here. The implementation itself... I guess it's just a bunch of QLine s on a QGraphicsScene . The realtime part is handled by calling repaint or paintevent or whatever it's called periodically, or setting up a complex animation.

Answer 2

Qt之上的Qwt库对此非常有用 。
