Revision 1434, 6.5 kB (checked in by arnonym, 15 years ago)

Make the PanelManager? a QWidget again.

Instead we introduce a new FFADOWindow that is the mainwindow. And we have this window appear before we try to connect to dbus which should make the look and feel a bit more consistent for non-console users. And the retry-question is not asked via QMessageBox anymore but with an in-gui widget. Which also obsoletes some predefined loops for retry...
