Question

I need to run slot only on doubleClick with left button mouse, instead of both.

// this->myComponent is a QTableView
   connect(this -> myComponent, SIGNAL (doubleClicked (const QModelIndex & )), this,
  SLOT (performSomeAction(const QModelIndex & )));

With this event, double click works in both cases, but needed only with left button click.
How I can do it?

this -> myComponent => QTableView

Answer 1

I found the following solution:

this -> myComponent -> viewport() -> installEventFilter(this);

bool MyClass::eventFilter(QObject *obj, QEvent *event) {
  this -> event = event;
  return QWidget::eventFilter(obj, event);
}

…

if (this -> event -> type() == QEvent::MouseButtonDblClick) {
  QMouseEvent * mouseEvent = static_cast <QMouseEvent *> (event);

  if (mouseEvent -> button() == Qt::LeftButton) {
    // do something....
  }
}
