[maemo-developers] osso, muali , dbus and Qt closeEvent()s

[From: Antonio Aloisio]

Hi,
IMHO using the Qt D-Bus API to rewrite some parts of libosso is more
easy that resolve the symobls, load and use libosso in Qt.
Kimmo said adding D-Bus dependencies in the widget is ugly, I agree
with him.. but... is this also true for the QStatusBar?

In Qt we have a statusBar that manages and displays messages.
Currently this status bar is hidden just because we don't have it in
Hildon. I don't compiled out in order to preserve
the compatibility with the Qt Desktop application.

Adding D-Bus into the status bar, we can display messages using hildon
passive notification dialogs just calling

void QStatusBar::showMessage ( const QString & message, int timeout = 0 ).

Is it cool? Any comment is welcome.

Cheers,
Antonio
