Tanner Doshier	6538f60322	overview: Connect app-drag signals to show/hide overview elements Anytime we begin dragging an app launcher, ensure the overview elements are showing. While searching, if an app-drag ends or is cancelled, hide the overview elements, but don't switch back to windows (which was the old behavior). https://bugzilla.gnome.org/show_bug.cgi?id=682050	2012-11-01 12:58:12 -04:00

Jasper St. Pierre	bc8965fe63	overview: Center the main overview group accordingly Using the same logic as the panel which smartly centers everything, smartly center the overview contents if we have enough space to do so.	2012-11-01 12:58:11 -04:00
Tanner Doshier	e7fcce3484	overview, workspacesView: Use ThumbnailsBox for independent workspace thumbnails Both WorkspacesDisplay and ThumbnailsBox need to know when windows have been restacked. Instead of each tracking changes on their own or trying to call each other, have the overview keep track and do the calculations, emitting a signal with the result. https://bugzilla.gnome.org/show_bug.cgi?id=682050	2012-11-01 12:58:11 -04:00

Tanner Doshier	a3a3f24ed3	workspaceThumbnail: Rename show(), hide() and add new methods show() and hide() now slide the thumbnails in and out, respectively. The old show and hide are now _createThumbnails and _destroyThumbnails. We only care about these thumbnails while in the overview, so create them when entering and destroy them on exit. https://bugzilla.gnome.org/show_bug.cgi?id=682050	2012-11-01 12:58:11 -04:00

Tanner Doshier	9491f6bd23	dash: fix for shrinking dash while animating The this.actor.height > this._maxHeight check is needed because animating the dash out causes constant notify::height signals and so after each one the max height would shrink to the actor height causing the icons to shrink until eventually we get to 16px icons. This way, only increase maxHeight if the actor can be drawn bigger than it is currently set. https://bugzilla.gnome.org/show_bug.cgi?id=682050	2012-11-01 12:58:10 -04:00

Jasper St. Pierre	ab60c628e7	panel: Abstract the centered panel logic out into a ClutterLayoutManager Since we want to use this in the overview as well, put it into centerLayout.js Panel corners are disabled for now. They'll be added back eventually.	2012-11-01 12:58:07 -04:00
