While we have menu for an app icon open, we want to show the prelight
for the item instead of removing the prelight when the user mouses
away from the item and into the menu, and if there's a tooltip
(like for the dash), we want to show the tooltip immediately when
the menu is popped up.
https://bugzilla.gnome.org/show_bug.cgi?id=642871
It can be useful to avoid sending enter/leave events to the source actor
of a menu: this would be the case when the source actor isn't a menu item
that should participate in menu navigation but rather is some object
(like an app icon) that we want to indicate corresponds to the menu.

Inside the Shell, all the UI (including chrome, the overview, and
the actual windows) is not a child of the stage but of a special

tooltip will soon.

We need to update WorkspacesView._ZoomOut before calling
_updateWorkspacesGeometry() in show(), as otherwise the old

the user is already seeing in the application window.

Make summary sources look more clickable and highlight them when selected.
Highlighting the fully expanded summary source when selected matches the

Currently activating a window on a different workspace requires very

Main._nWorkspacesChanged was racing with Main._checkWorkspaces.
If _checkWorkspaces won the race, _workspaces was uninitialized.
Because of this, _checkWorkspaces only noticed workspaces

empty, and added a new, empty workspace.

In the case where the original actor is destroyed, we don't
show a snap back animation, so we need to destroy drag actor
as we would do in _onAnimationComplete.
https://bugzilla.gnome.org/show_bug.cgi?id=640781
If you have XFixes 5 (and corresponding xserver support) then we
add barriers on the panel and in the message tray corner so that
its easy to reach the corners even when there are monitors to the
sides of the primary monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=622655
If the user clicks a trayicon in the overview, drop out of the
overview before passing the click on to the icon. (We have to actually
wait for the overview animation to complete, in case the icon wants to
get a pointer grab, which it would not be able to do with the overview
active.)
https://bugzilla.gnome.org/show_bug.cgi?id=641853
If the pointer moves on or off the stage while another process has a
grab, we will lose track of it. One example of this is that if you use
a popup menu from a message tray trayicon, the tray will stay up after
the menu goes away, because the shell never saw the pointer leave it.
Add a new method shell_global_sync_pointer() that causes clutter to
recheck what actor is under the pointer and generate leave/enter
events if appropriate.
Of course, we can't actually tell for sure when another process has a
grab, so we need a heuristic of when to call this. Currently we call
it from Chrome._windowsRestacked(), which is not really the right
thing at all, but does fix the menu-from-trayicon case...
https://bugzilla.gnome.org/show_bug.cgi?id=630842
If the user clicks on the title of a trayicon's SummaryItem, forward
that click to the trayicon. Also adjust
gnome_shell_plugin_xevent_filter() so that if the trayicon takes a
grab as a result of this, we don't hide the message tray.
https://bugzilla.gnome.org/show_bug.cgi?id=630842
If you run a command from Alt+F2 that tries to get a server grab (eg,
xmag), it will fail if it starts up before the run dialog is finished
hiding.
Additionally, the run dialog currently stays focused while it is
fading out, potentially stealing keystrokes (or causing the user to
accidentally launch two copies of a program).
Change ModalDialog.close() to call popModal() immediately
Add a ModalDialog.popModal method, and call that before running the
RunDialog command. If the command succeeds, close the dialog as
before. If it fails, call ModalDialog.pushModal() to put things back
to normal before displaying the error.
https://bugzilla.gnome.org/show_bug.cgi?id=644857
When right-clicking on an AppWellIcon, the icon will become focused,
which (presumably via style-changed) invalidates its current
allocation, causing "icon.y" to return 0 until it has been
reallocated, messing up our idea of where in the AppDisplay the icon
is. Work around this by calling get_allocation_box() instead.

If there is a monitor to the right it is very easy to overshot the

Specify x-fill and y-fill true for the bin that contains the status
icon so the status icon will always be sized to our specified icon
size (24x24). This prevents pathological behavior for legacy status

they had content would "stick", and the icon would permanently
end up 1x1.

When we were knocking off workspace height to fix the ratio problems, we

Commit fcfd17e was overzealous when simplifying the previous spinner
animation, as a result the spinner now stays around when switching

If a workspace becomes empty due to a window changing to/from the

In commit 9bd22dc0, I introduced an API to load an arbitrary
.desktop file, not necessarily from the menu path. It turns
out this function was broken because it created ShellApp instances
that were *different* from ones that were cached normally.
As far as I can tell, we didn't initially use it. Then later
Util.spawnDesktop was created which used this function.
Remove this broken function and all callers; if we're loading
.desktop files from *outside* the menu path, we can look at
readding.
This patch also kills off Util.spawnDesktop in favor of callers
talking to ShellAppSystem directly, now that the latter reports
errors.

When new messages come in we want to scroll down so that the user
sees the incoming messages. The current implementation does not work
because it relies on a synchronous allocation hack which does not work
for unmapped notifications.
Fix that by connecting to adjustment::changed and scroll whenever the
adjustment changes which equals "new messages", "new timestamp" or

i.e when the user scrolls back to read something don't scroll to the bottom.

If we're dragging a window around and we need to reposition the windows,
due to e.g. the sliding in of the thumbnails or some other reason, then we
need to consider the original position of the dragged window, rather than
the currend drag position. Otherwise we will unnecessarily rearrange the
other windows for instance on snap-back if you moved the dragged window
past some other window.
https://bugzilla.gnome.org/show_bug.cgi?id=643786
We currently show the workspace in the overview in a rectangle
with the same aspect ratio as the screen. Originally this was
probably done since it showed the desktop, but we don't do this
anymore, and the positioning of the windows in the overview is
strictly a grid, so its not in any way related to monitor geometry.
Additionally, in the multihead case the screen aspect ratio is
very different from the overview monitor geometry, so a lot of
space is lost.
So, instead we just fill the entire inner rectangle of the overview
with the workspace. However, the way the zoom into and out of the
workspace right now is by scaling the workspace so that it covers
the entire monitor. This cannot really work anymore when the workspace
is a different aspect ratio. Furthermore the coordinates of the
window clone actors are of two very different types in the "original
window" case and the "window in a slot case". One is screen relative,
the other is workspace relative. This makes it very hard to compute
the cost of window motion distance in computeWindowMotion.
In order to handle this we change the way workspace actor positioning
and scaling work. All workspace window clone actors are stored in
true screen coordingates, both the original window positions and the
in-a-slot ones. Global scaling of the workspace is never done, we
just reposition everything in both the initial zoom and when the
controls appear from the side.
There is one issue in the initial and final animations, which is that
the clip region we normally have for the workspacesView will limit the
animation of the clones to/from the original positions, so we disable
the clip region during these animations.

During a drag-and-drop, our pointer grab keeps enter/leave events from
being delivered. That means that after the DND ends, whatever actor is
under the pointer won't have received the enter event it should have,

By paying attention to the actors we leave and enter we can figure out
what widgets we need to call st_widget_sync_hover() on after the drag.

PopupMenuManager was pretending that it knew nothing about the menu's
sourceActors, while also trying to handle keynav between them. This
was a big mess, and resulted in bugs in navigation between panel menus
and the Activities button, and it totally gets in the way when trying
to add keynav to the dash (whose menu sources are arranged vertically
rather than horizontally).
Fix this up by moving the panel-specific parts to PanelMenuButton
instead.
https://bugzilla.gnome.org/show_bug.cgi?id=641253
It already doesn't work right, because the PanelMenuButton code
assumes that Left and Right won't be used as part of keynav within a

so this isn't a regression. To be fixed later.

Commit b1654af406 moved the panel positioning (and thus that of its
corners) before the panel startup animation. As the panel corners now
are mapped while the panel animation is active, the initial style-changed
signal which triggers another repositioning is received after the
initial layout and the corners end up at wrong positions.
To fix, animate the corner positions as well during the startup
animation - if anyone could actually see the animation, the corners
should animate with the panel anyway ...

Mutter really expects this, as this is how app-specified struts
happen. For instance, if the primary display is beside a taller
screen and is not positioned at the top, then we extend the struts
for the panel with the size of the unused area above the primary
monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=642881
Right now we require a strut to be as wide as the full screen to
create a TOP strut. This means that in a multi-monitor scenario (at
least if the primary monitor is leftmost) we will make the panel strut
be Meta.Side.LEFT due to the random side picking for corner objects.
This changes the width/height comparison to the primary monitor rather
than the screen to get this right. Also adds some docs about how
struts work in a multi-monitor situation.

Increase the icon size of search results for consistency with the
application view. To account for the larger icons, only display
a single row of results per section.
https://bugzilla.gnome.org/show_bug.cgi?id=643632
Search results' meta info currently is expected to have an 'icon'
property holding a Clutter.Texture of a fixed icon size. This
property is used to implement the createIcon() function of BaseIcon,
which is used to actually display the result, ignoring the size
parameter due to the fixed icon size.
Given that all available search providers create this property for
the desired icon size using a function with the same signature, it
appears logical to replace the fixed-sized 'icon' property with
such a function, so that the icon size will be defined by the display
actor rather than the search system.
https://bugzilla.gnome.org/show_bug.cgi?id=643632
Currently section headers in the search view are reactive and run
the corresponding provider's expandSearch() function when clicked,
which should launch an external program displaying all search
results for the section. Unfortunately it is only implemented for
the "Settings" provider, and does not work properly (as it ignores
the search and just launches System Settings).
Also current mockups deemphasize the section header, making the
feature pretty much indiscoverable (except by accident when
interfering with swipe-scrolling).
In conclusion, the feature does not make much sense in its current
form, so remove it.

Currently the total number of matches for a particular section is
