Fade effect when showing the menubar

[David Prieto]

Since Unity's last update, the menubar is hidden "behind" the titlebar in the top panel but it shows up when you hover your cursor over the top panel.

I think it would look really nice if there could be a very quick fade effect between and the other, thanks.

The current toggle approach is for implementation purposes. A fast fade
is preferable (patch welcome) and the design goal is a proximity effect
transition, like the blurring of notifications on approach, but X isn't
playing nice for us on that right now.

This isn't really "bitesize"...

Nathan, thanks a lot for taking the task!
I would be more than happy to provide help if needed. Don't hesitate to give us a shout.

@Florian Boucault: I've found a solution that may work...but it's my first bugfix and I am struggling with adding a new source file to the build list. I run "cmake . && make clean && make" and it gives me an error about 'undefined reference to vtable...' I think I added the new class wrong, any ideas?

[Nathan Moos (nathan-moos)]

Never mind #4, I've figured it out.

[Florian Boucault (fboucault)]

@Nathan: you rock. I am eager to see your work!

[Nathan Moos (nathan-moos)]

Sorry I haven't posted a fix yet, I just realized that I need to actually set up Unity 2D on Natty. I'm struggling with that. As soon as I fix that, I'll release my fix.

Alright, got started on a fix and am running it on my own desktop. I'm running into trouble as the menu bar is never displaying. I looked in the output and saw the following:

Unity 2D Panel: [WARNING] void DBusMenuImporter::GetChildrenCallback(int, QDBusPendingCallWatcher*): "No such method `GetChildren'"

Any ideas as to what that is?

[Florian Boucault (fboucault)]

@Nathan: I don't know if that warning is related to your problem. If you publish your changes for us to see we will be able to help you better. Thanks!

[Nathan Moos (nathan-moos)]

@Florian: Will do as soon as I can.

@Florian: Uploaded to lp:~nathan-moos/unity-2d/fix-for-691776

Glad to see the global menu finally getting some love again.

However, I dont think the Proximity/fade proposal will work properly if we dont take into account this other big global menu problem/bug:
