Context menu long left click on QGraphicsTextItem
-
Hello,
I try to have a context menu in Qt if we do a long press on left click on a QGraphicsItemGroup. I have try basic thing like this:
my .h:
@
class myclass: public QMainWindow
{
Q_OBJECT
public:
myclass(QWidget *parent = 0);
~myclass();public slots: void contextMenuEvent(QContextMenuEvent *event); private: Ui::myclassClass ui;@
my cpp:
@ 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 ?

Hi and welcome to devnet,
One way would be to implement mousePressEvent and mouseReleaseEvent and use a QTimer for the delay.
Also, note that you are having a memory leak here since you never delete menu.
Hope it helps
