[Interest] Embedding QWindow

[rap]

Your question arises a question of the purpose and usefulness of QWindow class regarding opengl if you can not easily create UI 
controls to go with it, at least in a SDI application.   I'll check how things turn out with MDI and QWindow for child wnds.

>You can embed a  QWindow inside a QWidget using QWidget::createWindowContainer.

OK, however the help file doesn't paint a very promising picture of the usage of QWidget::createWindowContainer.
