Merge lp:~mterry/indicator-appmenu/emit-show-now-changed into lp:indicator-appmenu/0.3

[Michael Terry]

This branch notices changes in its client window Status property and turns them into emissions of show-now-changed on the IndicatorObject. This is in the service of making Alt presses show the appmenu.

This branch requires [1] to work at all and [2] to be useful.

I think that we need to ensure that the one we're switching from wasn't
setting the status to alert as well. I think that the best way to do
this to track the state and see if it changes as we change menus.

review: Needs Fixing

[Michael Terry (mterry)]

But right before that bit of code, we removed all entries, so there shouldn't be a problem.

Though there is a bug, because that bit is called before we set up the new entries, so it when it iterates over entries, they won't have been added yet. I can fix that, but I'm not sure I grok the issue you mentioned.

[Michael Terry (mterry)]

There. Now the code won't notify about new entries' statuses before notifying that the new entries even exist.

But I still don't think we have to worry about old entries' statuses, because we've already notified that we removed them.

109. By Michael Terry on 2011-03-09

notify about new entries' statuses after adding new entries, not before

[Ted Gould (ted)]

I agree, I had forgot that we were deleting them so that would effectively invalidate their status. Looks good.
