Instead of showing submenus on the left side, make PopupSubMenuMenuItem
act like an expander. The sub menu is toggled on click, opened on
right/enter/space on the parent item, closed on left on any item
or when closing the parent menu.

As all children were considered for the grid's layout, hidden items showed up as
empty space. Instead, exclude hidden children from the layout, so that the grid is
only made up of visible items.

According to the designers, system notifications should be transient;
so now that transient notifications are supported properly, make use
of it instead of using a timeout to remove the associated source.
Transient notifications are removed after being shown. If the summary
is being shown while they appear, they are represented in it by a new
source icon.
We always create a new source for new transient notifications to
ensure that they don't replace the latest persistent notification
associated with the source. Because we generally don't want any
new or resident notifications to be replaced by others, associating
multiple notifications with a source is the next thing we will
implement.
https://bugzilla.gnome.org/show_bug.cgi?id=633412
Resident notifications don't get removed when they are clicked or
one of their actions is invoked, and are only removed when the app
that created them requests them to be removed or sends another
notification.
Remove the source when a notification associated with it is removed.
Except if the source is a tray icon.
Make sure that we pop down the tray when a notification is clicked
or one of the actions of a non-resident notification is selected.
Based on the initial patch by Jonathan Matthew.

Given that the grid view is gone there is no point in animating the

Mixing submenu menuitems and toggle menuitems results in poor layout.
The fix is to right-align the submenu arrows. Since we already need to
right-align the battery percentages as well, add alignment support to
PopupBaseMenuItem.addActor(), and update stuff for that.
Also remove the "column" param from addActor() since it hadn't
actually been implemented correctly before.
https://bugzilla.gnome.org/show_bug.cgi?id=633476
Since we are keeping a current pointer position anyways, we
don't have to continually call global.get_pointer() which is
a round trip to the magnifier; make ZoomRegion simply fetch
a current position stored in the Magnifier object.
https://bugzilla.gnome.org/show_bug.cgi?id=633553
Change the proportional algorithm so stop moving the zoom region
when cursor is in a "padding region" at the edge of the screen.
(The padding region is a 10th of the screen at 2x zoom, and smaller
for higher zooms.)
Based on earlier versions from Jon McCann and Florian Muellner.
https://bugzilla.gnome.org/show_bug.cgi?id=629950
This basic point of this change is to avoid always creating a
hidden Clutter.Clone actor for the default present-but-not-active
zoom region. The position of the viewport and region of interest
are now stored in member variables, and the actors are only created
and updated when the region is active.
Other significant changes:
* Unused public functions are removed or made private
* The mouse tracking position is immediately updated when options
like the zoom are changed, not just on the next mouse motion.
* ZoomRegion.setROI() now updates the zoom, not just the position;
a FIXME is added to the D-Bus interface for a place where the
D-Bus interface contains duplicate possibly conflicting information
* Lens-mode is now only effectively off when the magnifier is
fullscreen, instead of actually modifying the member variable;
this makes things work properly when changing out of full-screen
mode.
* When the clamping to screen edges is turned on, we now immediately
clamp.
* The handling of setting the position to fullscreen as compared
to just setting the viewport to fullscreen is untangled.
https://bugzilla.gnome.org/show_bug.cgi?id=633582
The magnifier should be enabled/disabled via the appropriate
GSettings key - otherwise the setting gets out of sync with the
actual state of the magnifier.
https://bugzilla.gnome.org/show_bug.cgi?id=636151
The popup menus of application icons in both the dash and the app view
are positioned on the right of the icon. In the case of the dash this
results in the menu being displayed off-screen in RTL locales, so move it
to the opposite side instead.
https://bugzilla.gnome.org/show_bug.cgi?id=635645
In some circumstances, a boxpointer would draw itself with the arrow
partially overlapping the rounded corner, causing things to not line
up correctly. Don't do that.
And while we're at it, don't draw the pointer very very close to the
corner either, since it looks odd if the corner flows directly into
the arrow.

Show a positional indicator where a new favorite will be added and
make the favorites re-orderable. Also allow the removal of favorites
using drag-and-drop according to the mockups.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
Delegate the emission of the window-drag-begin/window-drag-end
signals to overview functions, as done already for other items.
This will enable objects to react to those signals without having
access to the workspace objects / the workspaces view.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
Current mockups display all search results as icons as used by
application results, so change the default result display to use
iconGrid/BaseIcon. Remove the custom application results display,
as it is no longer needed.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
Add the view selector and adjust the positioning of elements in the
overview. Unlike the old dash, the view selector is made public to
indicate that extensions may add additional views or search providers.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
As workspaces will appear as a particular view in the view selector,
merge WorkspacesControls and WorkspacesManager to control workspaces
and related controls, so that a single actor can be added to the
selector instead of positioning the elements from the overview.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
The new layout does no longer support view switching, so merge
GenericWorkspacesView and SingleView, and remove MosaicView.
Also rename or remove workspace properties and functions which
are now unused.
The grid will have a comeback with the new DND behavior.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
Being no longer an independent menu pane, both the toggle() and
close() functions are no longer needed, and the view's structure
can be simplified a bit.
Also update the style to fit into the view selector.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
The view selector should only deal with view switching, so move the
logic to deal with search (find-as-you-type, cancelling a search,
navigating/activating results) into the SearchTab.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
The view selector is a tabbed interface with a search entry. Starting
a search switches focus to the results' tab, ending a search moves the
focus back to the previously selected tab. Activating a normal tab
while a search is active cancels the search.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
With the new layout, search results will be displayed in an independent
view like window previews, applications and possible future additions;
it does not make much sense keeping it with the switching logic, so move
the code to its own file.
Also remove the dash-prefix from the relevant style classes.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
The new dash implementation is a single-column vertical sidebar,
whose items are scaled dynamically to fit the available height.
If the height is still exceeded after scaling down to a minimum
item size, excess items are cut off.
The now unused old dash implementation is renamed to OldDash, as
its code will be used as a base for the new view selector element.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
As the button to add workspaces will move to the same position as
the new workspace drop area in drag mode, the latter is redundant
and can be removed.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
Overlaying inactive workspaces with a gradient to fade out the actors
does no longer work when re-using the normal desktop background. If
we keep the current DND behavior, we probably want to implement a real
fade effect - for now, just remove the visually disruptive shadows.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
While scaling the desktop background with the window previews represents
workspaces quite intuitively, the approach is not without problems.
As window previews in the overview behave quite differently to "real"
windows, the representation of workspaces as miniature versions of
"real" workspaces is flawed. The scaling also makes the transitions
to and from the overview much more visually expensive, without adding
much benefit.
Leaving the background in place provides more visual stability to the
transitions and emphasizes the distinctive behavior of elements in the
overview.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
The layout of recent mockups occupies the space previously reserved
for the info bar with the view selector. As the bar's purpose is
mainly to provide the user with feedback, it makes sense to use the
existing message tray facility instead of moving the bar elsewhere.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
The scrollbar is the main culprit for cluttered controls in the
linear view - all its functionality is already provided by the
workspace indicators, so it is save to remove the scrollbar in
order to clean up the interface.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
When the last message is older than SCROLLBACK_IMMEDIATE_TIME (1
minutes), show a timestamp in the middle, indicating the time it
was sent.
Use the same style for presence changes, but show them on the left.

NotificationDaemon-based notifications have markup in the banner/body,
but Telepathy-based notifications don't. (Eg, an XMPP message
containing "<b>foo</b>" should show up angle brackets and all, not as
bold.) Fix MessageTray.Notification to allow explicitly specifying
where there should and shouldn't be markup, and use that
appropriately.
https://bugzilla.gnome.org/show_bug.cgi?id=610219
According to the HIG we should use ellipsis when:
"Label the menu item with a trailing ellipsis ("...") only if the command requires further
input from the user before it can be performed. Do not add an ellipsis to items that only
present a confirmation dialog (such as Delete), or that do not require further input
(such as Properties, Preferences or About)"
So adjust the use of ellipsis to match that.
Pointed out by Michael Monreal.
We updated the normal devices part, but we forgot the part about
the primary device (possibly because it is not reported as such
in case it is fully charged). Update that as well, to avoid showing
weird GIcon serializations.

Reimplement UI without any indication of percentage or mutedness,
and whitout switches. The only interaction point is slider, but
it still supports mute changing for applications that track it,

If the drag actor is destroyed as part of a drag target accepting it,
we were not calling ungrabEvents, meaning the mouse/keyboard remained
grabbed until you clicked somewhere to cancel it.
This fixes that without trying to improve the extremely confusing
control flow...
https://bugzilla.gnome.org/show_bug.cgi?id=635278
Previously, when snapping back a drag actor, we moved it back to its
original stage-relative position and scale. This worked fine if its
parent was still in the same place it was when the drag started, but
failed in cases like the linear workspace layout window drag-and-drop,
where dragging a window would "zoom out" its parent workspace, causing
the snapback to send it to the wrong place.
Fix this by instead snapping the actor back to "where the actor would
have been right now if it were still at its original scale and
position within its original parent actor" rather than "where it was
before the drag started"
https://bugzilla.gnome.org/show_bug.cgi?id=635272
Instead of hiding the drag actor temporarily to determine the actor
beneath it, make it invisible to picks while dragging using the new
shell_util_set_hidden_from_pick().

The code to draw the root background has now been moved into Mutter,
with added smarts to not draw obscured portions. Remove the old

Add a "gicon" property so that a GIcon can be used instead of an
icon name, while still getting icon recoloring from the theme.
Also include a compatibility wrapper in libshell until GJS has
support for interface static methods.
https://bugzilla.gnome.org/show_bug.cgi?id=622451
gnome-volume-control-applet was renamed to gnome-sound-applet when
moved to the control-center module, so we need to check for both names
when identifying the legacy status icon.
It was decided at GNOME Summit that we would remove the invisible
setting until we have a better story for how it works with chat
and other sharing/messaging applications. We'd also need to
figure out how it relates to busy.
The action is far less common than powering off. It is mostly
used for performing system updates so the update tool should
offer the option directly. Also, currently the Shut Down option
dialog offers Restart anyway. We would like to keep the number
of entries in this menu as limited (close to 7) as we can.
Switch from St.TextureCache.load_named_icon() to using St.Icon for named
icons. Along with the advantage of getting colorization right for symbolic
icons, this allows moving some icon sizes into the CSS.
In the CSS, the system status icon size is changed to be 1em (=16px for the
default font size), at the request of the artists. See bug 613448.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
gnome-settings-daemon has moved to GSettings for most settings, we
should adapt as well. The only remaining GConf key is for metacity

Waiting for LookingGlass to close after calling St.set_slow_down_factor()
is annoying so divide the time for opening and closing by the slow-down
factor.
As popup menus now take focus for keyboard navigation, no application
is focused when activating the menu. Use the target application instead,
which keeps track of the application currently associated with the menu.
https://bugzilla.gnome.org/show_bug.cgi?id=634103
Action names sometimes unintentionally overlap with icon names, so
we should only create icon buttons if the message tray source requests
it. For the notification daemon, this is done by setting the
'action-icons' hint on the notification.
The previous notification server capability used to advertise this
feature, "x-gnome-icon-buttons", has been removed in favour of the
new capability described in the notification spec, "action-icons".
https://bugzilla.gnome.org/show_bug.cgi?id=624584
We shouldn't hide the tray as quickly if the user might have left it
unintentionally, such as when moving the mouse over to a different tray item or
using the scroll bar in the chat notification.

This way the new modal level is independent of whatever may have been
happening before. Fixes a problem with status menus becoming active
again from inside the app switcher, etc.
Tray icons replaced by a shell version are automatically filtered
and never make to the tray container, but when removed by the client
we were still trying to remove them from the tray, causing a warning.

Each menu is a focus manager group, but there is also some explicit
focus handling between non-hierarchically-related widgets. Eg, to move

The constructor was setting this.active to reflect the switch state,
which is wrong; this.active indicates whether or not the item is

Adding a "PopupMenuRadioButtonItem" wouldn't work well, because we'll
need radio-button indicators on multiple different styles of menu
item. Also, the current design draws the indicator in the menu item's
padding, so it's sort of special anyway. So just add support at the
BaseMenuItem level.
Also, redo the menu/menuitem padding so that all the horizontal
padding is in the menu item, or else the indicator dot will show up in
the wrong spot.
https://bugzilla.gnome.org/show_bug.cgi?id=631193
When there are menu items with right-aligned items, all the
right-aligned items should appear to the right of all the left-aligned

Clutter doesn't have an equivalent of GtkSizeGroup, so hack something up
using ShellGenericContainer and some javascript.
https://bugzilla.gnome.org/show_bug.cgi?id=631193
Rename a few, and add Suspend and Restart, although currently they do
the same thing as Shut Down (ie, they bring up a dialog that lets you
do any of those three). This will be fixed later when we have the
in-shell modal dialogs for these features.
https://bugzilla.gnome.org/show_bug.cgi?id=631193
In the new mockups, the user menu icons are on the right, not the
left.
Also, get rid of the idea of optional icons; the design doesn't have
icons on those items, and there probably aren't going to be symbolic
versions of some of those icons anyway. So if the caller specifies
PopupImageMenuItem, then always show an icon, and just use regular
PopupMenuItems for the items that don't have icons in the current
design.

_volumeChanged should not update the icon if the sink is muted.

Although within St itself there are situations where the semantics of
these functions (return TRUE or FALSE and return the actual value in
an out parameter) is useful, it's mostly just annoying at the
application level, where you generally know that the CSS property is
going to specified, and there is no especially sane fallback if it's
not.
So rename the current methods to lookup_color, lookup_double, and
lookup_length, and add new get_color, get_double, and get_length
methods that don't take an "inherit" parameter, and return their
values directly. (Well, except for get_color, due to the lack of (out
caller-allocates) in gjs.)
And update the code to use either the old or new methods as appropriate.

Tray icons control their own lifespan; they're not supposed to
disappear when you dismiss their notifications like non-trayicon
notification sources do.
https://bugzilla.gnome.org/show_bug.cgi?id=631042
Previously, when you clicked on a notification, it would call
this.source.clicked(), which would emit a 'clicked' signal on the
source, and then various other stuff would happen from there. This
used to make a little bit of sense, when clicking on a notification
was supposed to do the same thing as clicking on its source, but makes
less sense now, when clicking on the source itself *doesn't* call
source.clicked()...
Change it so that when you click on a notification, the notification
emits 'clicked' itself, and the source notices that and calls its
notificationClicked() method, and the various source subclasses do
what they need to do with that, and Source no longer has a clicked
method/signal.
https://bugzilla.gnome.org/show_bug.cgi?id=631042
Redo the way that the summary item expand/collapse animation works so
that the items all resize in unison so that when moving from one to
another, the summary area as a whole stays a constant width rather
than wobbling slightly.
(Also rename all references to the "minimum" summary item title width,
since it's not a minimum, it's just the width.)
https://bugzilla.gnome.org/show_bug.cgi?id=630546
This fixes the bug when the body would be missing from the expanded notification
that has a short body that used to fit in the one-line banner and is expandable
because it has action buttons.
We always want to add the banner to the body of an expandable notification,
unless the notification has custom content. We used to only do that when
creating this._scrollArea for the content. We should also do that when creating
this._actionArea .
https://bugzilla.gnome.org/show_bug.cgi?id=631566
It's possible that an item that was added to the summary got removed before
we had a chance to show the summary because the user has interacted with
the notification (e.g. clicked on an application ready notification). We should
not be showing the summary with an unchanged set of items in this case.
However, it is possible that multiple items were added to the summary before
we had a chance to show the summary, and only some of them got removed. In view
of this scenario, we can't just use a boolean flag to indicate if the summary
needs to be shown, but have to maintain an array of new summary items instead.
https://bugzilla.gnome.org/show_bug.cgi?id=630939
Environment.init() uses Shell.Global, which is not accessible outside

Introduce Cairo-drawn sliders to be used in PopupMenus (for example for
volume). They are stylable to some extent (colors, border width, slider
height) and have the standard behaviour of a slider, except they are
completely modal (once you start dragging, all events are intercepted by
the slider, which thus is kept active and highlighted at all times).
They show numeric values between 0 and 1 (scaling must be performed outside)
and emit value-changed on button release, but no activate, keeping the
menu open.
https://bugzilla.gnome.org/show_bug.cgi?id=625029
PopupMenuManager now connects to the destroy signal of PopupMenu, so
that destroying a PopupMenu is now enough for removing it from the

Icons can be loaded as St.Icon.SYMBOLIC, FULLCOLOR, APPLICATION or
DOCUMENT. The first will look for a symbolic equivalent, the second
looks for a full-color version (and does fallback, eg, from

full-color icons without fallback (as specified by the icon spec).
And update various callers to use the right flags.

Both current design and new mockups use square icons. Currently this
is implemented by setting a fixed width and height in the CSS, which
does not work for the growing/shrinking items in the new sidebar.
By moving the assumption of square items into the code, the size will
adjust according to icon size, spacing, padding and font size if not
explicitly overwritten in the CSS.
https://bugzilla.gnome.org/show_bug.cgi?id=625887
The current design features a sidebar where the icon size shrinks
automatically to fit more items. Add a setSizeManually parameter
to BaseIcon, which disables sizes read from CSS and allows to use
BaseIcon.setIconSize() to support this.
https://bugzilla.gnome.org/show_bug.cgi?id=625887
All mockups now use a representation for documents/places similar to

The actor emitted by ShellTrayManager is now ShellTrayIcon, a subclass
of ShellGtkEmbed which has several properties on it which are (or will
soon be) useful to the shell.
Part of the rearranging to use ShellTrayIcon means that we now show
the ShellEmbeddedWindow before creating its ShellGtkEmbed, which
requires a few modifications to ShellEmbeddedWindow (notably, telling
it at construct time what stage it will be drawn on, since it needs to
know that before it has a ShellGtkEmbed now).
https://bugzilla.gnome.org/show_bug.cgi?id=608869
Resolve a notification's ShellApp before posting the notification, so
that notification sources now always have an app associated (assuming
they came from an app as opposed to the command line). Index sources
by PID rather than by appName (so that, eg, multiple calls to
notify-send now show up as separate sources).
For Sources that have an associated app, use the app's icon for the
source, rather than tracking the notification icon.
This change also lets us get rid of appNameMap, since we can just use
shell_app_get_name() now.

Introduce the Universal Access status indicator as designed, modeled

This patch allows the icon in PopupImageMenuItems to be changed at

This patch ensures the following notifications behavior:
- Urgent notifications that have long title or banner text are auto-expanded
correctly.
- Single-line notifications that have _expandNotification() called (e.g.
because the user mouses over to them), are treated as expanded, which means
they get fully expanded if they are updated with more content and the user
can escape them.
- The position of expanded notifications is updated when they are updated.
- Notification banner is shown again on the first line if it can fully fit
there after a notification is updated, even if it was previously hidden
because the notification was expanded and the old banner did not fully fit.
- New notifications are immediately hidden if the user mouses away from them.
- If a new notification is updated while it is shown, we extend the time it
will be shown.
- If a new notification is updated while it is hiding, we stop hiding it and
show it again.
- If a summary notification is updated while it is hiding, we let it finish
hiding and show a new notification with the updated information.
Implementation details:
- Single-line notifications now have 4px bottom padding instead of 8px, which
means that their height matches the tray height, they are fully shown in the
banner mode, and don't pop out by 4px when the notification is expanded.
- Notification keeps a flag that indicates whether it is expanded, updates
its expanded look when it is updated, and emits an 'expanded' signal
indicating that its layout has possibly changed. The message tray connects
to this 'expanded' signal when it is showing a notification in the expanded
state and updates the position of the notification accordingly when this
signal is received so that the notification is fully shown. This is better
than connecting to 'notify::height' signal on the notification bin, since
it results in fewer callbacks.

The Shell is the only user of the magnifier, so there's no
reason to keep using GConf for its settings. Since it's a
session-wide tool, use a distinct schema,
org.gnome.accessibility.magnifier, stored in
/desktop/gnome/accessibility/magnifier just like before.
Put these settings in a separate schema file for clarity.
Old enums in GConf were stored as integers, we now use the
facilities provided by GSettings to save them as strings,
and convert them to integers automatically thanks to the
mapping stored in the schemas. Remove hard-coded default values,
which we can get from the schemas.

Expanding notifications automatically just because they popped up where
the pointer is positioned distracts the user. It can also lead to a behavior
that is surprising to the user by, for example, making the user's input
switch to the notification's text entry box.
It is possible to expand a notification that popped up over the pointer
by mousing away from it and then mousing back in immediately.
https://bugzilla.gnome.org/show_bug.cgi?id=617209
We used to keep long titles ellipsized when a notification was expanded,
which was a bug. We now show them fully by line wrapping them.
Based on the original patch from Steven Van Bael.
https://bugzilla.gnome.org/show_bug.cgi?id=623970
We used 'bannerBody' flag to differentiate the case when we move the banner to
the body when the notification is expanded from the one when we don't do that
and only use the custom content set for the notification, as is the case for
Telepathy notifications. We also always cleared the content of the notification
on update when bannerBody was set to true.
Flag named 'customContent' reflects the use case for it more clearly. The
comments that accompany it were also updated and improved.
We now always add the banner text as the first element in the expanded
notification unless 'customContent' flag is set to true.
If the 'body' parameter is specified, we use it in addition to the banner
text. The earlier version of the code had a bug that resulted in the 'body'
parameter not being set only in the case when the 'bannerBody' was set to
true and the banner text had newlines in it.
https://bugzilla.gnome.org/show_bug.cgi?id=623970
The banner should not be appearing briefly when we are hiding the notification.
For that, we should only restore the opacity of the banner in popInCompleted()
when we are done hiding the notification. We do need to restore the opacity
in case the notification is updated and is shown in the banner mode again.
The banner should not be appearing briefly when we are showing the notification
in the summary mode. For that, we should not use the animation time to fade out
the banner in popOut() for summary notifications.
These two problems were particularly visible when the ANIMATION_TIME was increased.
https://bugzilla.gnome.org/show_bug.cgi?id=623970
In Clutter 1.2, clutter_event_get_keysym() ignored the state of the
Shift key. In 1.4, it does not, so we have to adjust our comparisons
accordingly.
https://bugzilla.gnome.org/show_bug.cgi?id=627782
The old calculation did not take into account the icon and the spacing
between columns. This resulted in the notifications that had a slightly
longer title/banner combination than could actually fit not being expandable.
The new calculation is done in _bannerBoxAllocate() so
that we don't need to hardcode which other elements are present.
https://bugzilla.gnome.org/show_bug.cgi?id=627985
A Source needs exactly one summary icon (which in the case of a
trayicon-based source won't even be just an image), but possibly many
notification icons, which may vary for successive notifications
(particularly in the case of NotificationDaemon notifications). So
differentiate these cases in the API.
https://bugzilla.gnome.org/show_bug.cgi?id=627303
The tray itself does not actually need them, and to make status icon
sources work correctly the NotificationDaemon will need to be tracking
its sources by two separate IDs, so the existing system won't work.
Also remove MessageTray.removeSourceByApp(), which is
NotificationDaemon-specific, and implement the functionality in
notificationDaemon.js instead.
https://bugzilla.gnome.org/show_bug.cgi?id=627303
The current search system uses the OR operator to concatenate search
terms. While results which are matched multiple times sort before
other matches, it is almost guaranteed that adding an additional term
to the search increments the number of results, which is rather
surprising.
https://bugzilla.gnome.org/show_bug.cgi?id=610955
When calling Notification.update, reuse the previous _bannerBox and
related labels (only changing the label content and relayouting), so
that the opacity set on popOut is preserved. As a consequence, updating
an opened notification no longer shows (or flicker) the banner at the
top.

The start date is shifted by a week if the day number of the month's

It is not obvious that only the icon is clickable to activate the
default action - in fact, with the area being that tiny, many don't
even know that notifications can be clicked.
Just extend the clickable area to the whole notification.

Adds class PopupSwitchMenuItem, which is a two-state switch similar

In addition to already grabbing focus in the summary notifications,
we also want to grab focus in the new notifications when the user
hovers over them and expands them.
The notifications that expand automatically will only get focus once
the user hovers over them. The notifications that don't expand will
never grab focus because they don't need it.
Make sure that we toggle the way we grab focus when switching between
the overview and the main mode. This is necessary because, unlike
summary notifications that pop down when the user moves between the two
modes, new notifications keep being shown as long as the user hovers
over them or until they time out.
https://bugzilla.gnome.org/show_bug.cgi?id=617224
Because clicking on the summary item to have it display its notification
is a more deliberate action than hovering, we can now grab focus in that
notification. This makes chat notifications in the summary more convenient
to use because you don't need to click on the text entry there.
We pop down the notification when the user clicks anywhere outside of it,
triggers the overview, or the run dialog.
https://bugzilla.gnome.org/show_bug.cgi?id=617224
This ensures that the summary appears when we are showing a new
notification and switch to the overview at the same time.
Another effect of this patch is that the summary is shown if the
user moves the mouse to the bottom right corner while a notification
is being shown, which is ok.
This patch adds the method "removeMenu" to PopupMenuManager, to allow
for removal of menus after they're inserted. In order to do this, it
needs to store along with the menu all the relevant signal connections,
that are disconnected when the menu is removed.
Also adds a parameter "position" to "addMenu", so that menus can added
in arbitrary order (in particular to reintroduce those which were removed).
This patch is intended towards dynamic menu users, like extensions for
application lists, docks, sidebars showing recent documents or favourites,
as well as advanced system tray implementations.
https://bugzilla.gnome.org/show_bug.cgi?id=622730
In GSettings, a change notification is generated immediately from context of the _set() call.
In GConf, The "value_changed" signal is emitted whenever the server
notifies your client program that a value has changed in the database (100% NOT from context of the _set() call).
https://bugzilla.gnome.org/show_bug.cgi?id=624296
We need to only connect to 'action-invoked' on notification once
when the notification is created. We were accumulating callbacks
otherwise, which resulted, for example, in the Rhythmbox skipping
through multiple tracks when the 'Next' button was hit.
Always be sure to destroy the notification when its source is
destroyed, which is the case when an action is invoked.
Note that in the future, we might not want to destroy the source
for some notifications when an action is invoked. For example,
it makes sense to keep Rhythmbox in the tray while the music is
playing and allow the user to use the controls from the summary
notification too.
Solved by splitting the base class (PanelMenuButton) in a separate
module, ui.panelMenu, which is meant to hold also other reusable
button classes.

The spinner animation moving from left-to-right to indicate a starting
application changes its direction on reaching the end of the movement.
Instead, keep the spinner at the right of the app name until startup
has finished.

We should not be showing the cursor in the search entry in the overview
if the user's input will be appearing elsewhere, such as in the run dialog,
in the Looking Glass console, or in the notification's response field.
"text-align" allows setting the alignment of text, with respect to
other lines and allocated space, without requiring a reference to
the ClutterText (which is private for most widgets).
If not specified, all text is left-aligned.

This is part of the design update for the message tray.
Source now takes an extra argument called 'title'.
All expanded message tray items are same width, which is determined by
the width of the item with the longest title, up to MAX_SOURCE_TITLE_WIDTH.
This is done so that items don't move around too much when one is expanded
and another one is collapsed.

While the contents of the left and right group in the panel are

It has probably crossed the line to evil by a mile or so, but here

Use GSettings for all Shell configuration. GConf is kept to read
configuration from external programs (Metacity, Nautilus and Magnifier),
but ShellGConf is removed because it's mostly useless for the few calls
we still have. Also get rid of unused GConf code in ShellAppSystem.
A basic GConf schema is still used to override Metacity defaults and
configure Magnifier in a system-wide fashion. GConf is also used as
GSettings backend via the GSETTINGS_BACKEND environment variable.
All of this will be removed when these programs have been ported
to GSettings and able to use dconf.
GLib 2.25.9 is required. Schemas are converted to the new XML format,
and compiled at build time in data/ so that the Shell can be run from
the source tree. This also requires setting the GSETTINGS_SCHEMA_DIR
environment variable both when running installed or from source tree,
in src/gnome-shell.in and src/gnome-shell-clock-preferences.in.

The shell design says that upon launching an application,
no X window should have focus, and we should display an
animated launching indicator.
Implement this by in panel.js, keep track of the last started
application. If there isn't currently an X focus, show an animation
for the last starting application.

While zoomed out in drag mode, the workspaces at the left and right
of the active workspace are slightly transparent - when switching
workspaces, one of the transparent workspaces becomes the new active
workspace, but its opacity is not updated.
https://bugzilla.gnome.org/show_bug.cgi?id=620940
When in drag mode, the linear view raises a transparent actor
covering the entire stage. That way the view can handle events
like dragging items to the screen edges, but in order to not
disable any drop target not handled by itself, it duplicates
huge amounts of code from dnd.js.
Cleanup that mess by using the new drag monitoring support.
https://bugzilla.gnome.org/show_bug.cgi?id=620504
Sometimes it is desirable to be able to react to DND events that
happen outside a target actor's bounds, e.g. to implement reactive
screen edges. Add a simple interface which allows to hook into
drag motion and drop handling without jumping through ugly hoops.
https://bugzilla.gnome.org/show_bug.cgi?id=620504
The design calls for item to not appear abruptly, but not too slow
either - 100ms seems to be a good sweet spot for elements which are
supposed to appear "instantly".
Add a fade effect to the alt-tab popup and set the timings for other
fade effects to 100ms.
https://bugzilla.gnome.org/show_bug.cgi?id=621247
We query the transformed position and size of the popupMenu before actually showing

Add _st_actor_contains() in st-private for use within St, and

Currently, we use 'gtk-yes', 'gtk-no' and 'gtk-media-pause' as
user status icons. It seems more logical to use the dedicated
icons from gnome-icon-theme instead.

First, we were passing an incorrect timestamp to
meta_display_focus_the_no_focus_window - fix that.
The invocation of set_focus_app to the started app there couldn't
really work, because (if the above call had worked) we'd get the
X reply *after* the started app.
What we need to untangle here is the distinction that's now made in
ShellApp between _STATE_STARTING and _STATE_RUNNING. A nice way to
start doing this is to rebase ShellWindowTracker to only be concerned
with app states. Concretely, the current "has windows implies
running" logic now lives just inside shell-app.c.
Rename the app-running-changed signal to be app-state-changed. This
will ultimately be useful so that inside the panel, we can track
the last started app.
https://bugzilla.gnome.org/show_bug.cgi?id=620899
Currently the workspaceSwitcher does not take the screen size into account
which could result into overflowing the screen.
Fix that but using Shell.GenericContainer instead of St.BoxLayout which takes

https://bugzilla.gnome.org/show_bug.cgi?id=620404
Before adding a new entry to the history, we check that it does not
match the previous entry to cut down the number of duplicate entries.
Part of that condition is a check for a history length greater zero
to avoid an illegal negative index, with the side effect that nothing
is ever added while the history is empty.
https://bugzilla.gnome.org/show_bug.cgi?id=621123
As the design calls for smooth transitions whenever possible, use
a similar fade effect for the all-apps and more-docs menus as for
the panel menus.
https://bugzilla.gnome.org/show_bug.cgi?id=620775
When the app well doesn't contain any applications, it displays a placeholder text
to indicate that it's a drop target. When porting WellGrid from St.Bin to St.BoxLayout,
the call to set_child() to set the text was overlooked.
https://bugzilla.gnome.org/show_bug.cgi?id=617281
Currently, only the base style class is set in the constructor, the
style update according to the state of the represented app is deferred
until the actor is shown.
As existing icons are destroyed and recreated when the number of icons
changes, this behavior causes the icons of running apps to flicker if
CSS transitions are used.
Set the style directly in the constructor and update the code to not
delay style updates until the actor is shown - StWidget does defer
expensive calculations until the actor is mapped anyway.

As the search entry captures the pointer when activated, the hover

Separate out the main app view into different sections based on the categories
in the desktop file. The configuration is done via gmenu and the desktop menu

gs-applications.menu, which we install.
There is no support for "submenus" - only the menus directly under
Applications will be displayed as categories.

Currently we only relayout when the screen size changes, this gets
the cases where a monitor gets added/removed but not when the primary

We need to relayout on all monitor layout changes.
Remove ShellGlobal::screen-size-changed signal as it is no longer used, Gdk is
used to track changes now.

Currently we don't get any drop events for dual screen modes with a screen

While zoomed out, the workspaces view's drop target spans the entire
monitor to implement reactive screen edges. When a drop event is not
handled by the view, an attempt is made to pass it on down the stack,

as well.
Also improve the code which translates dnd coordinates to target
positions.

Currently, the drag and drop code assumes that on a successful drop
the target will either consume the drag actor or that it is otherwise
OK to destroy the actor.
As the drag behavior for window preview was changed, dropping a preview

option to restore the actor in case of a successful drop as well.

First, simply set the ellipsize flag on the application menu labels.
Next, rework how we lay out the panel components so that the center

than pushing it around.
Previously, as part of making the shell not obviously explode if
one had a lot of tray icons, we allowed them to push the clock over.
Instead, go back to just failing in this case; we need to exile legacy
tray icons, not be slightly less ugly.

Switch from having separate METRICS and METRIC_DESCRIPTIONS objects
in a perf module to a single METRICS array. This is done so the
perf module can define the units for each metric.
In addition to improving the output in the web interface, the purpose
of having units is to give some clue about how to pick from multiple
values from different runs. In particular, with the assumption that
"noise" on the system will increase run times, for time values we want
to pick the smallest values, while for "rate" values, we want to pick
the largest value.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
When SHELL_PERF_OUTPUT is set, instead of just dumping out the metrics, dump
a more complete report with:
- Event descriptions
- Metric descriptions and value
- Event log
Helper functions shell_perf_log_dump_events() and shell_perf_log_dump_log()
are added to ShellPerfLog to support this. The gnome-shell wrapper is adapted
to deal with the changed report format.

Add some basic statistics for allocated memory based on mallinfo(),

We want to be able to summarize the behavior of the shell's
performance in a series of "metrics", like the latency between
clicking on the Activities button and seeing a response.
This patch adds the ability to create a script under perf/
in a special format that automates a series of actions in the
shell, writing events to the performance log, then collects
statistics as the log as replayed and turns them into a set
of metrics.
The script is then executed by running as gnome-shell
--perf=<script>.
The 'core' script which is added here will be the primary
performance measurement script that we use for shell performance
regression testing; right now it has a couple of placeholder
metrics.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
To support scheduling performance-measurement scripts that want to run
a number of actions in series, add shell_global_run_at_leisure() to run
a callback when all work is finished.
The initial implementation of this is not that accurate: we track
business in Tweener.js via new shell_global_begin_work(),
shell_global_end_work() functions, and we also handle the case
where the main loop is continually busy.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
We don't need to reposition the menu every time its button is
allocated; we can just stick it in the right place when we pop it up
(which is guaranteed to not be during a layout cycle).
(This means that now we won't reposition the menu if the button
moves/resizes while the menu is already popped up, but it's not clear
that we'd want it to anyway, since that could easily result in the
user selecting the wrong item, etc.)
Also, we don't need to override the menu's width any more, so remove
that.

Per design discussion, change things back so that when choosing
an individual window, we raise only that window. However
when we select an application, raise all windows.
A behavioral change required to clearly differentiate these
is that when the window thumbnail list is popped up, it no
longer has the first window selected by default. Therefore
the user has to explicitly press the down arrow or use the
mouse to enter individual window selection mode.
https://bugzilla.gnome.org/show_bug.cgi?id=617959
The ShellGlobal initialization performs several actions like connecting
to the X server, ensuring directories exist, etc., that are problematic
because we were creating the object even when running the binary for
introspection scanning. During compilation we may not even have X11
available in e.g. autobuilder type environments, and it's just a
bad idea to connect even if we do.
Avoid this by deferring creation of the ShellGlobal object
until the plugin is actually started.
Now that we're initializing things later, remove the connection to
screen changes, and initialize cached ShellGlobal state at the point
when the plugin is set. The root pixmap actor is now sized initially
on creation too. Instead of relying on screen-size-changed being
emitted on startup, explicitly invoke _relayout().

Fetch the names of the user's "subscribed" contacts, and use the
SimplePresence interface to watch for available/away/busy/etc messages
and create notifications for them.
Currently we display notifications when switching between "available"

and "away"/"busy" we just add the information to the chat window
without popping up a notification, to avoid spamming the user with
"Bob's screensaver activated" messages.
