Click event for QListWidgetItem

@JonB
Thank you for your reply!
No, I don't get in this loop when I click on a QListWidgetItem.

if(event->type() == QEvent::MouseButtonPress)

Thank you for your reply!
Then, is there any other workaround apart from using the signal slot mechanism?

However, the control never goes into the second if block.

I thought you had 2 ifs, I didn't see 3 :( !

By second, I meant this one only:

if(event->type() == QEvent::MouseButtonPress)

Yes. You need to work with QListQWidget::viewport. You can't do it directly on application event filter. See solutions discussed at https://stackoverflow.com/a/42475218/489865 (also https://www.qtcentre.org/threads/20961-why-QListWidget-can-t-get-QEvent-MouseButtonPress) and consider if you can integrate them into your approach (which I have no idea why you are doing, but that's up to you).

BTW: Installing an event filter on QApplication directly might not be the greatest idea. As your app grows the filter- and event delivery mechanism might become very buggy and laggy as a result of your code that is executed on basically anything that happens within your app.

Thanks, this worked.

So, are you suggesting to create separate event filters for each window?

Just like QListQWidget's events are processed in its viewport, is there something similar for a QCalendarWidget?

I used this event filter to capture the click event on my calendar widget:

bool Class::eventFilter(QObject *obj, QEvent *event)
{
    if(obj == ui->dateEdit->calendarWidget()) {
        if(event->type() == QEvent::MouseButtonPress) {
                qDebug() << "Calendar Widget Clicked";
        }
    }
    return QObject::eventFilter(obj, event);
}

But the control never goes in the second if block.

It worked by installing the event filter on the table view of the calendar widget:

ui->dateEdit->calendarWidget()->findChild<QTableView*>("qt_calendar_calendarview")->viewport()
