QLabel* CountLabel = new QLabel(tr(" count:"));
QLineEdit* countValueLabel = new QLineEdit(QString("% 1").arg(count));
countValueLabel->setStyleSheet("background: rgb(236,236,236); border: 0 px;");
countValueLabel->setBuddy(countValueLabel );

class customisedLineEdit: public QLineEdit {

}

customisedLineEdit::customisedLineEdit(QString string)
{
setText(string);
setReadOnly(true);
setStyleSheet("background: rgb(236,236,236); border: 0px;");
setContextMenuPolicy(Qt::CustomContextMenu);
}

void customisedLineEdit::contextMenuEvent(QContextMenuEvent event) {
printf("\n here in contextMenu:");
QMenu menu = createStandardContextMenu();
QAction* copyAction = new IN_CURRENT_POOL QAction("Copy",this);
menu->addAction(copyAction);
copyAction->setShortcut(tr("Ctrl+C"));
connect(copyAction,SIGNAL(triggered()),this,SLOT(copy()));
menu->exec(event->globalPos());

delete menu;
event->accept();

}

I do not get any menu on RMB . Could you suggest how to get only copy in ContextMenu for QlinedEdit

@Qt-Enthusiast said in Copy from QLineEdit using Pop up menu:

void customisedLineEdit::contextMenuEvent(QContextMenuEvent event)

It must be

void customisedLineEdit::contextMenuEvent(QContextMenuEvent *event) 

as you can see here http://doc.qt.io/qt-5/qtwidgets-mainwindows-menus-example.html
Is contextMenuEvent called?

@Qt-Enthusiast

When Qt::CustomContextMenu is set on the widget, contextMenuEvent() handler is not called. Instead QWidget::customContextMenuRequested() signal emitted.

Removed setContextMenuPolicy(Qt::CustomContextMenu) or like this:

connect(this, &MyLineEdit::customContextMenuRequested, [=](const QPoint &pos){
    QMenu *menu = createStandardContextMenu();
    menu->addAction(tr("My Menu Item"));
    menu->exec(mapToGlobal(pos));
    delete menu;
});
