This fixes two minor inconveniences:
- When closing the chat window and re-showing it from the systray icon, the geometry was not properly restored. The window was always shown in the middle of the screen. Now, one gets the window back with it's actual last position and size.
- It is now possible to not only show the window from the systray icon, but also to close it. This is the way other chat programs do it (Kopete back in the day, Konversation, Quassel IRC etc.)
At first I noticed it wasn't working like it should, then realised it
was using APIs that are largely unadvised. Also I saw there's some kind
of system to render numbers in there but this is also something we
generally do not do. There's better ways to display such information
(e.g. using the com.canonical.Unity interface), so I wouldn't bother
having ad-hoc code in there. And if we need to have it, we better have
it in KNotifications.
It now will also use the icon from the theme.
