[Qt-interest] How to assign keyboard shortcuts to tab close buttons

[Maik Friedmann]

Hello,

I've been using Qt 4.5 and enhanced QTabWidget features. I have an
application whose main widget is a QTabWidget. It is set to
documentMode and each tab has a close button. It is working perfectly,
but I need to assign keyboard shortcuts to those close buttons
(specifically Ctrl+W), similar to Firefox. I failed to do this; I
tried to create a global QAction, tried to get a reference to close
button with tabWidget->tabBar()->tabButton(idx) and assign a shortcut
to it without success.

Any idea how to implement this?

Regards,
Maik
