I solved my problem via event filter of scene. ui->graphicsView->scene()->installEventFilter(this); bool MainWindow::eventFilter(QObject* obj, QEvent* event){ if(event->type() == QEvent::GraphicsSceneMousePress){ if(ui->addServerBtn->isChecked()){ QGraphicsSceneMouseEvent* mouseSceneEvent; mouseSceneEvent = static_cast<QGraphicsSceneMouseEvent *>(event); Server *serv = new Server(mouseSceneEvent->scenePos().toPoint()); scene->addItem((QGraphicsPixmapItem*)serv); } } return false; }

The problem is solved please check this https://forum.qt.io/topic/113640/solved-why-q-window-events-are-eaten-by-qml-item thanks

@hobbyProgrammer said in window closes after completing certain actions.: @JonB Hi, just a quick update. I think it does get there, but it prints this part before going executing the slot. It's really important for those who try to help you to give accurate description of what does/does not happen. Everyone was trying to figure how your connect() could not complete and get to the next line....

Hi, What about QGraphicsProxyWidget ?

@raven-worx It works !!! Thank you !!! Now I just have to see if I can check it into the scene (maybe create a widgetitem for the viewport, I'll see.

Hi and welcome to devnet, Can you explain why do you need to know whether a letter is currently pressed ? A long press on such a key usually triggers the auto-repeat of the system so it might make things a bit more difficult.

@Chris-Kawa turns out, you were spot on! I had some difficulties to compile my "fix" in release configuration. So I went and rewrote the class, with your comment in mind. I intoduced a new signal and changed the overrides accordingly. void signalEvent(QMouseEvent::Type t, QPoint p); now, I don't need the timer, it also works in debug as well as in release mode... virtual void mousePressEvent(QMouseEvent *e) Q_DECL_OVERRIDE{ emit signalEvent(QMouseEvent::MouseButtonPress, e->pos()); QPushButton::mousePressEvent(e); } works like a charm. Thanks!

@JLimbocker Tried your code but unfortunately it does not exactly what I want. It is selecting from the beginning instead of from where I was clicking when dragging. Problem with passing the mouse event through to the TextField is that when I do that using mouse.accepted = false. The other handler like onRelease: are not called on the MouseArea anymore which destroys my handling there. The selectAll() could be switched off when something is already selected but I do not know why that TextField's selection is starting from the beginning... Anyone knows how to forward the mouse events to an underlying element but still have the complete handling in the MouseArea available? That would solve my question.

@EarthHobbit Hi This sample works for me (i can click it ) #include <QApplication> #include<QGraphicsScene> #include<QGraphicsDropShadowEffect> #include<QGraphicsPixmapItem> #include<QMessageBox> #include<QGraphicsView> class myGraphicsPixmapItem: public QGraphicsPixmapItem { public: myGraphicsPixmapItem(QPixmap pixmap): QGraphicsPixmapItem(pixmap) { }; ~myGraphicsPixmapItem() { }; void mouseReleaseEvent(QGraphicsSceneMouseEvent* event) { QMessageBox::information(NULL, "Information!", "Mouse release Detected!"); }; }; int main(int argc, char* argv[]) { QApplication app(argc, argv); QGraphicsScene scene; QPixmap pix(200, 200); QPainter* paint = new QPainter(&pix); paint->setPen(QColor(255, 34, 255, 255)); paint->drawRect(0, 0, 200, 200); myGraphicsPixmapItem* pixmapItem = new myGraphicsPixmapItem(pix); pixmapItem->setFlags(QGraphicsItem::ItemIsMovable); delete paint; QGraphicsView view(&scene); scene.addItem(pixmapItem); view.showFullScreen(); return app.exec(); }

Nevermind - in the end it turned out the label was modeled as a separate QLabel instead of the text of the QCheckBox. Once I removed the label, and put the text inside the checkbox, I got exactly what I was asking for.
