I finally found a method that works, that I want so share:
void myWidget::moveEvent(QMoveEvent *event)
{
Qt::MouseButtons mouse = qApp->mouseButtons();
if(mouse != Qt::LeftButton)
{
std::cout << "move end" << std::endl;
}
}
If you check the mouse status in the moveEvent(), on the last move event the mouse will not be pressed anymore, which is kind of like a mouse release event. At least it works for me at the moment.
