How to detect when a QDialog is clicked anywhere?

[stampede]

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.
