[Solved] Window Active Focus signal

[bundickt]

Is there a way to know when a window looses active focus without polling isActiveWindow? I would like to connect to a signal if possible.

Try "this":http://doc.qt.nokia.com/latest/qapplication.html#focusChanged or "this":http://doc.qt.nokia.com/latest/qwidget.html#focusInEvent

you are looking for the focus or for isActiveWindow? that's a difference, because for the activeWindow, one child may also have the input focus.

If it's about activeWindow, you could check "QWidget::changeEvent":http://doc.qt.nokia.com/4.7/qwidget.html#changeEvent and emit a custom signal

I used the focusChanged signal from QApplication.

I feel like there should be a better way of doing this without having to watch every focus changed event and check if its the focus change I'm looking for.

Thanks for the help.

The point here is, there are many things that could be more elegant for few people, but then we would have thousands of signals.

Personally I like the idea of having thousands of signals.

Qt Quick seems to be designed with this philosophy.
