When nesting QGraphicsViews, the inner QGraphicsView does not get any mousePressEvents for the right mouse button. It though works correctly for the left mouse button. mouseMoveEvent and mouseReleaseEvents are not affected.
This behavior is observed when the window flag is set to something different than Qt::Widget, i.e., Qt::Dialog. See sample source below.
class View: public QGraphicsView { public: View() { setWindowFlags(Qt::Dialog); } ~View(){} protected: void mouseMoveEvent(QMouseEvent *me) { if (me->buttons() == Qt::LeftButton){ cout << "View::mouseMoveEvent -> LeftButton" << endl; }else if (me->buttons() == Qt::RightButton){ cout << "View::mouseMoveEvent -> RightButton" << endl; } } void mousePressEvent(QMouseEvent *me) { if (me->buttons() == Qt::LeftButton){ cout << "View::mousePressEvent -> LeftButton" << endl; }else if (me->buttons() == Qt::RightButton){ cout << "View::mousePressEvent -> RightButton" << endl; } } void mouseReleaseEvent(QMouseEvent *me ) { if (me->button() == Qt::LeftButton){ cout << "View::mouseReleaseEvent -> LeftButton" << endl; }else if (me->button() == Qt::RightButton){ cout << "View::mouseReleaseEvent -> RightButton" << endl; } } }; int main(int argc, char *argv[]) { QApplication app(argc, argv); QGraphicsView view1; View view2; view1.setScene(new QGraphicsScene()); view2.setScene(new QGraphicsScene()); view1.scene()->addWidget(&view2); view1.resize(640, 480); view1.show(); return app.exec(); }
