QPushButton on Shift+Click?

Hi All,

I want to implement a QPushButton in such a way that it do something when user click it
for which I can use clicked() signal but I also want that when user click while shift button is pressed then it will do something else.

How can I do it?

Thanks

you can subclass QPushButton and reimplement keyPressEvent or you can install event fillter for your button and process QKeyEvent.

Thanks for reply.

Can you give some sample code for doing it.

sorry, not QKeyEvent, but QMouseEvent :)
1. subclassing

Code:

---

void MyPushButton::mousePressEvent(QMouseEvent *e)
{
      if (e->modifiers() == Qt::ShiftModifier) {
           //do what you need
           return;
      }
      QPushButton::mousePressEvent(e);
}

2. installFilter

Code:

---

...
pushButton->installEventFilter(this);
...
 
bool MyWidget::eventFilter(QObject *obj, QEvent *event)
{
    if (obj == pushButton && event->type() == QEvent::MouseButtonPress) {
         QMouseEvent *mouseEvent = static_cast<QMouseEvent *>(event);
         if (event->modifiers() == Qt::ShiftModifier) {
             //do what you need
             return true;
         }
    }
    return QWidget::eventFilter(obj, event);
}
