GNOME Bugzilla – Bug 91853
Multiple instances of capplets
Last modified: 2011-02-01 03:34:28 UTC
I tested with sunbeta 2 build 4 package. source taken from gnome-2-0 branch with timestamp "Tue Aug 20 13:26:01 BST 2002". 1. select "desktop preferences"->accessibility->keyboard. 2. enable "toggle key" 3. select "repeat key preference". this will invoke "keyboard applet". 4. In "keyboard applet" select Accessibility. 5. This will invoke new instance of accessx screen. 6. Select "repeat key preference". this will invoke "keyboard applet". This is a cyclic one. so we will multiple instance of keyboard applet and accessx applet running, which doesn't look good.
The same thing will happen with every capplet if you click on their icons multiple times. This is not accessX specific
but this way of cyclic doesn't happen in other applets.
The same problem happens if you push the 'accessibility' button in the keyboard capplet multiple times.

it really makes no sense from a usability standpoint to have more than one instance of a cc capplet on the screen (even the user tries to run a second one). I know for instance, rhythmbox will only let you run one instance of it as well.
Now. "The screen" is ambiguous. It doesn't make sense to have one capplet per head; it only makes sense to have 1 capplet per machine. However, in a networked world it does make sense to have a capplet open on 2 machines simultaneously. So any "one instance" checking would have to be such that _if_ certain daemons worked over the network (even if they don't at the moment) multiple instances on the network would still work. I don't know enough about session management etc. to explain what I mean better than that. My 2p anyway.
andrew good point. I think i'm just use to thinking in terms of single user workstations :) but yeah i think we basically are saying the same thing.
Updating status_whiteboard field to reflect A11Y team's assessment of accessibility impact.

any news on this? (despite the dups)

(In reply to comment #13) > any news on this? (despite the dups) Yeah, kinda embarrasing to file dups of a bug almost four years old ;-) IIRC that there was talk of getting code into GTK or some gnome lib (don't really remember) that would make single-instance apps easier to make. Perhaps that is of help here?
What Sergej is probably referring to is Emmanuele Bassi's GtkUnique, however we are going to need to wait a bit before we can do that. I'm adding this bug to the tracker bug for potential users of GtkUnique, or whatever. Bumping version since you can still have multiple instances of the same capplet running.

The control-center doesn't use separate applications anymore (in GNOME 3), but uses a single shell window in which the settings panel can be switched.
