[Qt-interest] System-wide shortcut (hotkey)

[Anthony Serdyukov]

Thanks, I'm looking at QAbstractEventDispatcher too, and that is why.

In the documentation for QCoreApplication::winEventFilter I have found
the following:

<cite>
It is only directly addressed messages that are filtered. To handle
system wide messages, such as messages from a registered hot key, you
need to install an event filter on the event dispatcher, which is
returned from QAbstractEventDispatcher::instance().
</cite>

So, what kind of hot keys are mentioned here... don't know. And how to
register it properly?
