EventFilter detecting object

[xcalzada]

I am using the eventFilter to detect the object clicked.

I have two kind of differents object

QLabel and QPushButton.

I am using this piece of code:

bool minesweeper::eventFilter(QObject watched, QEvent event) {
if (event->type() == QEvent::MouseButtonPress)
{
const QMouseEvent const me = static_cast<const QMouseEvent>(event);
const QPoint p = me->pos(); //...or ->globalPos();
QWidget * const widget = childAt(p);

	const QLabel * const label = qobject_cast<QLabel *>(widget);
	const QPushButton * const label2 = qobject_cast<QPushButton *>(widget);
			
	if(label == null){
	cout<< "it is Pushbutton" <<endl;
	}else{
	cout<< "it is Pushbutton" <<endl;
	}		

}

Are there any way more elegance to do it?

Is dangerous the condition label == null? Because you are doing n static cast and could be not always is null.
