Web apps (Chrome/Prism) should have individual icons in Docky

Bug Description

It should be possible to have web apps treated as seperate applications with their own icon in Docky. If I'm not mistaken, this could be done by taking the windows WM_CLASS into account when grouping and fetching icons. For example, I can have a desktop file with the following:

[Desktop Entry]
Exec=chromium-browser --user-data-dir=~/.gmail --app=http://www.gmail.com --class=Gmail $*

* the --user-data option is required to start a NEW instance of chrome, otherwise it will hijack any current chrome instance and the --class argument will be ignored

This would launch an instance of Chromium/Chrome running gmail in app mode. It's window class would appear as follows in xprop:
WM_CLASS(STRING) = "chromium-browser", "Gmail"

As opposed to a regular instance which is just:
WM_CLASS(STRING) = "chromium-browser", "Chromium-browser"

Is it possible to group windows like this, based on their class? It would provide some great web app integration. I filed a similar bug on the chromium tracker about properly identifying individual app instances, through their class/role or otherwise.

As a work around:

For each web app, you can create a symbolic link to /usr/lib/chromium-browser/chromium-browser with a unique name (like "gmail"). And another launcher (see script /usr/bin/chromium-browser) which launches it, as well as specifying --user-data-dir and so on. Then, create a desktop file which points to the new launcher.

This will cause Do to think its a whole seperate program and will use the .desktop's icon and will not group it with existing chromium windows.

I imagine something similar could be done with prism/wine/etc until a better solution comes around..

Docky 1 (the Do theme version of Docky) has reached the end of its maintenance period and is no longer being supported. Docky 2 (the stand-alone application) is a complete rewrite and thus may or may not be affected by this bug.

Please feel free to install Docky 2 (PPA: https://edge.launchpad.net/~docky-core/+archive/ppa or souce: http://do.davebsd.com/wiki/Installing_Docky) and see if your bug still occurs. If it does, please file the bug against lp:docky (not lp:do!).

I confirm that this bug exists in Docky 2, version 2.0~bzr1067-0karmic1~dockycore1. I have added docky to this bug.

Brian, could you elaborate further on your workaround, and also tell us if it works with Docky 2?

I managed to get Gmail to appear as a separate app from Chrome, but it still doesn't match its launcher or get an icon.

Hmm. As often happens, this problem waited until I had wasted some other people's time complaining about it, and then magically fixed itself. Oh well. Sorry.

in Docky 2.0.0-Alpha-1 bzr docky r1067, if i put the application in the dock and run it, the opened window goes under Chromium

Here is after opening google reader chromium app http://picasaweb.google.com/lh/photo/IfIy2mAype0olR1KNT9Axw?feat=directlink

So the downside to this workaround is that if I use Ctrl+N or Ctrl+T to open a new window, it doesn't know to use my regular Google Chrome settings to do that -- it becomes part of the Gmail app as far as Unity is concerned.

This is not an optimal solution.
