double clicks should be disabled on bfb/Place launcher icon/double key press

Needs design discussion.

I'll confirm this, double click should do the same as click.

Mark

Probably triple click too!

Same with place icons in the launcher and multiple "request" (like double/triple super press).

Let's see how I can handle that generically.

From the attached merge request:

Don't ack double/triple click or super press on bfb and places icons.
(LP: #766776)
This is workarounded in different files right now, the correct fix will be to
handle that in the ubus level (too risky at this stage), added FIXME to remember
that for oneiric.

There is one glitch though, which cannot been tackled without the ubus rewrite:
- if you open a place, then, double click on a placeicon in the launcher to
  close it, it will be closed by will be reactivated (this is because we send
  the UBUS_PLACE_ENTRY_ACTIVATE_REQUEST again on click).
- so, the next super press will not show the home dash, but the active place
  (closing/opening it again will reset to the home dash)

I still think it's an improvment (see Charline's report in maverick for double
clicking on bfb and people being puzzled) and the last described glitch only
impact people double clicking on a place LauncherIcon for closing it…

Proposed fixes for unity-2d:
https://code.launchpad.net/~mardy/unity-2d/treat-double-clicks-as-single
(last 2 commits)

I tried to submit this with "bzr lp-propose-merge", but it crashed (I reported it as bug 788219, in case someone can guide me out of it).

I disagree with this “feature”, or at very least with its implementation. It means that when I accidentally click on the corner of the screen and realize that I didn’t want to open/close the menu, I have to wait half a second doing nothing before trying again. Even if I repeatedly click on the menu waiting for it to close/open again, it *never will*, as long as each click was within half a second of the previous one! That just makes the desktop feel unresponsive. (See bug 777492.)

This applies not just to clicks, but also to the keyboard shortcuts (Super and Alt+F2), which makes even less sense.

Frankly, is it really too much to ask the user to realize that when they try double-clicking on the menu button and see the menu briefly open and immediately close, they should try single-clicking instead?

The double-click suppression makes sense for launchers, but not for the main menu which is supposed to act as a toggle.

This bug was fixed in the package unity-2d - 3.8.8-0ubuntu1

There is no more bfb in Oneiric. This was done in Natty and acked by design then.
