MDI sub window's event handling?

[A Former User]

I have a widget inherited from QGLWidget which is added to MDI area with addSubWindow().

I implemented my widget's keyPressEvent(), making it output a line of text every time it is called.
But it seems not working -- I guess the key press event is captured by QMdiSubWindow, but not sure.

Well, for you desperate guys who found this page with google...

Just:

1. write a class P which inherites QMdiSubWindow;
2. reimplement QMdiSubWindow::*Event();
3. use QMdiSubWindow::setWidget(QWidget *);
4. call QMdiArea::addSubWindow(p). [here p is the instance of your class P]
