it's simple, just override virtual func mouseReleaseEvent() in MyOpenGLWidget : public QOpenGLWidget

Hi,

Like @m-sue asked, please show us how you did that. It's easy to sleep an error there for example a wrong or missing argument.

The mouse release event does work with a QOpenGLWidget. I use it all the time but I did have a problem with getting a mouse release event if this happened when the mouse was outside the area of the widget.

If you don't see any events at all it is possible you don't have the mouse events declared properly:

protected:
	virtual void mousePressEvent(QMouseEvent *event);
	virtual void mouseMoveEvent(QMouseEvent *event);
	virtual void mouseReleaseEvent(QMouseEvent *event);

If you are not seeing the mouse release event when the mouse position moves beyond the area of the widget you can change the focus policy in the constructor of your derived class to prevent this from happening:

	this->setFocusPolicy(Qt::StrongFocus);
