[Interest] Unusable native toolbars in Mac with Qt 4.8

[David Garcia]

Dear all

I have modified QWidgetPrivate::childAtRecursiveHelper with something that seems quite right:
if (includeFrame && qobject_cast<QToolBar *>(child) && qt_widget_private(child)->isInUnifiedToolbar )

instead of:
if (includeFrame && qobject_cast<QToolBar *>(child) )

This prevent the unified tool bar to capture events from other tool bars in the application.

Best regards,

   David

This bug prevents us from upgrading from Qt 4.7 (there is no support in Qt 5.2 for this feature, already discussed in this list in December). I will appreciate a lot a fix for the problem in the forth coming 4.8.6.
