Hi,

Is there anything wrong with this code?
It outputs all events the application receives.

I'm trying to get an application to accept drag events that originate from a different application. I noticed that my dragEnterEvent was not being called.

I wrote a minimal application (see below) to test.

The weird thing is I just upgraded from 4.6.1 to 4.6.3 and an application that used to received dragEnterEvent stopped doing so immediately. But I'm not sure right now if that is a co-incidence (I've been changing some code unrelated to DnD).

Here's the minimal project:

  7.     class MainWindow;

  10. class MainWindow : public QMainWindow
  11. {
  12.     Q_OBJECT
  13. protected:
  14.     bool eventFilter(QObject* o,QEvent* e);
  15. public:
  16.     explicit MainWindow(QWidget *parent = 0);
  17.     ~MainWindow();

  20.     Ui::MainWindow *ui;
  21. };
  22.  
  23. #endif // MAINWINDOW_H

  22.     if(e->type()==QEvent::DragEnter)
  23.         qDebug() << "QEvent::DragEnter"; // THIS IS NEVER OUTPUT
  24.     return false;
  25. }
