Qt - Find mouse screen x,y - even application closed.

Question

Hello, I'm new to Qt. I'd like a window to follow the mouse around the screen. (It's a useful aid to reading)

The best I can come up with is a timer that uses QPoint QCursor::pos() to move the window every .1 seconds.

Rather than spinning this timer constantly, is there an event system I can tap into? This would look smoother, and use less computer.

Is there a better way?

Thanks,

Mike

Answer 1

You can override QWidget::mouseMoveEvent() and update your window position there.

Answer 2

Try QTimer and its timeout() signal. The event system you're looking for is probably the main event loop, provided by the QCoreApplication or the QApplication classes.
