[Qt-interest] How to get mouse cursor position from QEvent

[Frederico Prado]

Use 

void YourQWidget::mouseMoveEvent(QMouseEvent *event)
{
    emit posChanged(event->pos());
}

Be sure to initialize MainWindow with:

YourQWidget->setMouseTracking(true);

And then you can connect the signal anywhere you want.

I hope this helps.

Regards,

Fred
