Yes, that makes sense. QGraphicsView uses the press event to determine which item will get subsequent mouse events.

So I cannot send a single mouse release event to any object, it's right?

Are you able to provide a runable example? BR, Martin.

The most mouse events can be simulated successfully except GraphicsSceneMouseRelease event. The onReleased handler still cannot be triggered. What's the matter? Hope you or others can help me again, thank you!

I want to simulate key and mouse events for testing my qml script automatically. Now, I can simulate the key event successfully by "item->scene()->sendEvent(item, &keyEvent);" But it cannot work when I call "item->scene()->sendEvent(item, &mouseEvent);" to simulate mouse event. I've tried another way "QApplication::sendEvent(view, &mouseEvent);", but it still cannot work. The return value is always false. My qml script is follow, it can output log when I click actual mouse key. Rectangle { id: container ...... MouseArea { id: mouseArea anchors.fill: parent onClicked: { mouse.accepted = true; console.log("Mouse Clicked! key: " + mouse.button + " | keys: " + mouse.buttons); } } Do you have any suggestion?
