How to detect when a QDialog is clicked anywhere?

[Lykurg]

What's about using QWidget::mousePressEvent() and close the widget there?

We have tried QWidget::mousePressEvent(), but It not works. This PopUp contains inside others QWidgets like QLabel, QGroupBox,... If the users click the PopUp in a area with no others QWidgets mousePressEvent works, but if the user click for example on QGroupBox widget then the mousePressEvent is not thrown.

Try to install event filter on every widget in the dialog:

MyDialog * dialog = new MyDialog();
// for each element in the window:
label->installEventFilter(dialog);
groupBox->installEventFilter(dialog);
// ...
 
bool MyDialog::eventFilter(QObject *obj, QEvent *event){
   if (event->type() == QEvent::MouseButtonPress) {
      this->close();
      return true;
   } else {
      return false;
   }
 }

MyDialog * dialog = new MyDialog();
// for each element in the window:
label->installEventFilter(dialog);
groupBox->installEventFilter(dialog);
// ...

bool MyDialog::eventFilter(QObject *obj, QEvent *event){
   if (event->type() == QEvent::MouseButtonPress) {
      this->close();
      return true;
   } else {
      return false;
   }
 }

This code is not tested by me, I'm just wondering.
