I am developing a simple program for a customer, which displays kitchen orders on a secondary monitor, generated by a hospitality system.

问题 What is the best (as in simplest) way to obtain the pos of a mousePressedEvent in a QLabel? (Or basically just obtain the location of a mouse click relative to a QLabel widget) EDIT I tried what Frank suggested in this way: bool MainWindow::eventFilter(QObject *someOb, QEvent *ev) { if(someOb == ui->label && ev->type() == QEvent::MouseButtonPress) { QMouseEvent *me = static_cast<QMouseEvent *>(ev); QPoint coordinates = me->pos(); //do stuff return true; } else return false; } However, I
