Context menu long left click on QGraphicsTextItem

Hello,
I try to have a context menu in Qt if we do a long press on a QGraphicsItemGroup. I have try basic thing like this:
my .h:

Code:

---

class myclass: public QMainWindow
{
	Q_OBJECT
public:
    myclass(QWidget *parent = 0);
    ~myclass();
 
public slots:
    void contextMenuEvent(QContextMenuEvent *event);
 
private:
    Ui::myclassClass ui;

---

my cpp:

Code:

---

void myclass::contextMenuEvent(QContextMenuEvent *event)
{
    if (event)
    {
        QMenu *menu = new QMenu;
        menu->addAction(new QAction("Action 1", this));
        menu->addAction(new QAction("Action 2", this));
        menu->addAction(new QAction("Action 3", this));
        menu->exec(event->globalPos());
    }
    }

---

It's work, but only with right click. And how to have this only on a QGraphicsItemGroup with a long left click ?

You can detect the pressEvent and then use a timer to measure the hold. If the timer fires before you detect a release you have a long-press. If the release happens before, you stop the timer.

For a QGraphicsObject subclass you could also try QGraphicsObject::grabGesture()

Cheers,
