Don't show the message tray in the overview by default. From now on the
message tray in overview behaves as regularly, i.e. it will slide up the
overview on Super+M keypress.
https://bugzilla.gnome.org/show_bug.cgi?id=693987
ScreenShield uses Notification.bannerBodyText to fill the body of detailed
notifications, so use a separate boolean property to indicate it was already
added to the body.
https://bugzilla.gnome.org/show_bug.cgi?id=693822
The notifications spec has two hints for playing a sound, sound-file
and sound-name. We can support them using the existing code that
wraps libcanberra.
https://bugzilla.gnome.org/show_bug.cgi?id=642831
The message tray currently operates in three modes: in the overview,
normal, and while the on-screen keyboard is up. The last case is
particularly odd, and exclusively used for chat-notifications. As
users can still use the Chat application directly on touch-only
devices, the additional mode isn't really justified, so remove it.
https://bugzilla.gnome.org/show_bug.cgi?id=662687
A pressure barrier is a barrier that activates after the user pushes
against the bottom of the screen in a short time. Implement this using
the new XInput 2.3 features that provide extended information about
pointer barriers, and use it so that pushing against the bottom of
the screen edge brings up the message tray.
https://bugzilla.gnome.org/show_bug.cgi?id=677215
While it is possible to keep track of removed sources by tracking
their summary items' actor:.destroy signal, a dedicated signal
mirroring the existing 'source-added' one is more convenient.
https://bugzilla.gnome.org/show_bug.cgi?id=693220
The designs says that only music notifications should be shown in full
in the screenshield, the others should be either shown as a summary or
with very light details.
https://bugzilla.gnome.org/show_bug.cgi?id=685926
Allow message tray sources to provide a NotificationPolicy object,
that will configure how and if the source is displayed. For notification
daemon sources, this object is hooked to GSettings.
https://bugzilla.gnome.org/show_bug.cgi?id=685926
Use the new Hash.Map class, and store signal connections along with
the source and summaryItem. This allows to remove sources without destroying
them.
https://bugzilla.gnome.org/show_bug.cgi?id=685926
During the box pointer animation, other events can trigger an updateState,
losing the information that the summary is hiding and thus never disconnecting
the signals. Then, this stale connections can cause stacktraces, as they
fire when summaryBoxPointerItem is null.
https://bugzilla.gnome.org/show_bug.cgi?id=692693
Hiding notificationWidget with a telepathy notification causes
unfocused to be emitted, which causes a reentrant updateState.
If another notification is queued, it is shown before the old
one is cleared.
https://bugzilla.gnome.org/show_bug.cgi?id=683986
These were lost when we moved away with StIconType. The idea was that
apps needed to include -symbolic in their action IDs, but apps were
not updated, and it never makes sense to have non symbolic icons there,
so let's restore the previous behavior.
https://bugzilla.gnome.org/show_bug.cgi?id=692091
This fixes the image and scrollbars peeking through in banner mode,
because StTable wasn't able to allocate them at the restricted height
imposed by CSS.
https://bugzilla.gnome.org/show_bug.cgi?id=692091
Switching style on Overview::hiding creates a weird effect, as the noise
texture is shown while the overview is still visibile. Instead, wait for
the tray to be fully hidden, then apply the new style.
As now the switch is invisible, there is no need for the transition
(which introduced the same problem on overview showing)
https://bugzilla.gnome.org/show_bug.cgi?id=689091
If the chosen action is not open, the tray should not be closed, to
let the user further interact with it (for example to mute or remove
more sources)
https://bugzilla.gnome.org/show_bug.cgi?id=689296
MessageTray._tween sets the state variable to the in-progress value,
so it must be sure that at the end of the animation the value will
be the corresponding final and nothing else will happen in between.
https://bugzilla.gnome.org/show_bug.cgi?id=683986
Turns out that tweener has a very complex logic to decide when a new
tween on the same properties overrides completely the old, and unfortunately
what we were doing was not enough in all cases.
Just be explicit, and don't let anything else mess with the state.
https://bugzilla.gnome.org/show_bug.cgi?id=688895
Open a modal dialog, try to open the message tray -> no effect, the message
tray is blocked by the dialog.
Close the dialog, try to open the message tray by pointer -> still
no effect, because the old timeout id was not cleared the first time,
so the dwell callback thinks the tray is about to open.
https://bugzilla.gnome.org/show_bug.cgi?id=688750
The top panel and message tray icons were by default a gnome foot and
are replaced by better ones. The applications icon is now using the
symbolic apps icon of the dash, and the windows icon is also improved.
https://bugzilla.gnome.org/show_bug.cgi?id=641303
MessageTray tweens both opacity and y to hide or show _notificationWidget,
but only y when expanding it. This means that an existing tween to hide
the notification will continue running, clearing the notification state.
If the hiding one completes before the showing one, the onComplete handler
will throw an exception (because the notification was nullified) and
therefore break the state tracking.
https://bugzilla.gnome.org/show_bug.cgi?id=683986
For now we just use it to assign an identifier to modal modes in
which we want to allow some keybindings, but we don't use it for
any actual filtering; we'll start doing this shortly.
https://bugzilla.gnome.org/show_bug.cgi?id=688202
At the moment, only the mouse can be used to focus and answer a chat
notification.
This adds a new keybinding (defaults to <Super>+n) to focus and expand
the active notification.
https://bugzilla.gnome.org/show_bug.cgi?id=652082
Notifications that are created in response to direct user actions like
"is ready" or "'foo' has been removed from favorites" should always be
displayed even though the user has marked him/herself busy.
https://bugzilla.gnome.org/show_bug.cgi?id=662900
When the summary notification is open when the tray is closed, we end
up with two concurrent animations: the notification fading out, and the
tray moving away from underneath it. Sliding out the tray should be the
primary transition here, so hide the notification immediately to not
draw the user's attention away from it.
https://bugzilla.gnome.org/show_bug.cgi?id=686888
Having the close button move away from under the pointer after
clicking it is confusing and distracts from the main transition,
which is hiding the notification. Just hide it immediately.
https://bugzilla.gnome.org/show_bug.cgi?id=682237
Rather than destroying the entire source, which is unintuitive, simply
close the notification. Removing the entire source is still possible
by right-clicking on the summary item and choosing "Remove".
https://bugzilla.gnome.org/show_bug.cgi?id=682237
Currently when the summary boxpointer is ungrabbed automatically
because the keyboard focus was moved outside the message tray
(for instance by selecting the overview search entry or opening
the right-click menu of a dash item), after the popup is hidden
_updateState() will grab focus and show the popup again.
Work around this by unsetting the clicked summary item when losing
focus to an actor outside the message tray.
https://bugzilla.gnome.org/show_bug.cgi?id=685156
Commit 448517032e added the message tray unconditionally to
the Ctrl-Alt-Tab popup, but while this makes sense for a normal
session, we do not want it in the login screen.
Be a bit more careful where we make the tray available.
https://bugzilla.gnome.org/show_bug.cgi?id=685914
Currently if a summary item signals that it has handled a click
itself, the tray hides itself. This behavior is wrong for the
On-Screen-Keyboard, which appears as a unit with the tray, so add
a property to opt-out of the default behavior.
https://bugzilla.gnome.org/show_bug.cgi?id=683546
This fixes a case of _updateState() being called recursively,
resulting in stray grab()/ungrab() calls the leave the entire
desktop in a stuck focus state.
https://bugzilla.gnome.org/show_bug.cgi?id=683546
The message tray is now modal and pushes the view up, but the keyboard
is shown below it. Solve this by applying a special styling to the
keyboard and message tray combination, and by not pushing the windows
up when the keyboard is shown.
https://bugzilla.gnome.org/show_bug.cgi?id=683546
When the tray is triggered by keybinding rather than dwelling, the
first summary item should be given key focus. Currently this is
achieved by grabbing the focus before toggling the tray, so that
the grabHelper will move the focus for us. However this interferes
with the grabHelper's focus save/restore mechanism - for instance,
after using the keybinding once, the tray will always come up with
the first item focused.
https://bugzilla.gnome.org/show_bug.cgi?id=682243
Currently it is only possible to use keynav inside the tray if it
has been triggered with the keyboard shortcut. Make it possible to
initiate keynav by hitting Tab in other cases as well.
https://bugzilla.gnome.org/show_bug.cgi?id=682243
Currently opening the summary boxpointer acts as a stop gap for
keynav - the only shortcut still working is "Escape" to hide the
tray altogether.
Change the handling of Escape to only close the summary boxpointer
and allow to use the down arrow as alternative (unless the boxpointer
already processes the key press itself of course, like the chat
entry does). Also add a Delete shortcut to dismiss the open summary
item.
https://bugzilla.gnome.org/show_bug.cgi?id=682243
When using keynav in the top bar, menus may be opened using the
down arrow; in a similar fashion, allow to open the summary
boxpointer with the up arrow.
https://bugzilla.gnome.org/show_bug.cgi?id=682243
_hideTray() is called by _updateState() when the tray is visible
but should be hidden; however, _updateState() may be called again
from within _hideTray() when releasing the GrabHelper grab, so
unless we update the _trayState variable before that, _hideTray()
will be called a second time.
https://bugzilla.gnome.org/show_bug.cgi?id=682243
The onUngrab callback already checks if all notifications are destroyed and
hides immediately if so. Previous code instead would leave state handling
in an inconsistent state, by not removing the grab, not setting
summaryBoxPointerState to HIDDEN and not disconnecting various signals.
https://bugzilla.gnome.org/show_bug.cgi?id=684036
Look at the focus window's interaction timestamp to catch the case
where the user is typing and knocks the pointer into the tray or
mouses down to the bottom of the screen and clicks on something.
If the focus window's interaction time differs at the start and
end of the tray dwell then we don't activate the tray.
https://bugzilla.gnome.org/show_bug.cgi?id=683811
As PAM messages are now shown below the password entry, there is no
need for this complexity, and we can just hide all notifications.
Also, this avoids the ambiguity between notification.showWhenLocked and
source.showInLockScreen, which have very different effects.

They are bigger and show an ellipsis if the count goes over 99. They

ClutterBinLayout is so amazingly broken: it uses the y_expand property to
find out if the children needs to honor alignment/fill, but that property is
"bubbled up" from the grand-children, so the notificationWidget would notice
the y_expand on the notificationBin (necessary to make the layout manager on
notificationWidget honor the alignment property for the bin), and would
receive the full height of the MessageTray actor from the parent's layout manager,
resulting in a notificationWidget shifting up, with the notification detached
from the screen.
https://bugzilla.gnome.org/show_bug.cgi?id=683628
Previous code had a mixture of fixed positioning and ClutterBinLayout,
and this was broken badly for autorun notifications.
Rewrite to use ClutterBinLayout and Clutter properties exclusively.
https://bugzilla.gnome.org/show_bug.cgi?id=683378
Commit 5c6b1fd0c modified the hierarchy of SummaryItem contents, by
introducing a notificationStackWidget in place of the StackView, but

https://bugzilla.gnome.org/show_bug.cgi?id=682683
Legacy tray icons may want to take a pointer grab to show a popup menu,
and this is incompatible with message tray modality. To solve this,
escape the tray when forwarding clicks to the tray icons, and wait
for the input mode change to actually synthetize the X event.
https://bugzilla.gnome.org/show_bug.cgi?id=682244
Each summary icon is 48x48 with a padding of 6px on each side. Thus,
each summary item is 60px wide. Therefore the summary mode should be
60px high instead of 72px.
Changed the tray actor to use a ClutterBinLayout so that it honors the
y-expand property of its children.
https://bugzilla.gnome.org/show_bug.cgi?id=682248
In multi-monitor setups, the screen might extend below the edge of
the monitor that holds the tray. In that case the tray is currently
triggered from a secondary monitor, which is rather surprising;
change the check to use the correct monitor geometry instead.
https://bugzilla.gnome.org/show_bug.cgi?id=683044
The height of an unexpanded notification could include expanded
content if the notification has extra widgets (like actions and images),
so tweening to that cause it to expand visually.
Instead, use the height of the message tray before the restyle
as an upper bound.
https://bugzilla.gnome.org/show_bug.cgi?id=682738
Showing the removable devices is potentially a security risk (as
they include network shares). Also, a nautilus launched from there
can't be used, so it's just a way to overload the system.

If the user has the mouse down - for example when they are selecting
text and dragging - then the attempt to get a modal grab will fail.
grabHelper: allow the .grab() function to fail and do nothing in this
modal case if the grab fails.
messageTray: handle grab failure and don't pop up the tray. Change the
logic for tray dwelling so that we only try to pop up the tray once
while the pointer is in the dwell area - this avoids the possiility
that the tray will pop up once the user releases the mouse.
https://bugzilla.gnome.org/show_bug.cgi?id=682385
Since dwell at the bottom of the screen is now the primary way of
summoning the tray, removing the hot corner to avoid having two
separate things that can be accidentally triggered.
https://bugzilla.gnome.org/show_bug.cgi?id=682310
If the user leaves the mouse pointer at the bottom of the screen for a second,
open the tray. This simulates the eventual plan of measuring "pressure" by how
far the pointer is moved past the edge of the screen. Measuring pressure will
take X server changes.
https://bugzilla.gnome.org/show_bug.cgi?id=682310
This code was originally here to close the summary box pointer if it was
already open, but it seems that it isn't necessary, and is causing all
sorts of problems.
Displaying a close button provides a discoverable way to close notifications.
Clicking the close button on new notifications, dismisses them, but doesn't
remove the notification source from the message tray if it is resident.
Clicking the close button on summary notifications acts the same way as clicking
"Remove" option in the right click menu, which is to remove the notification
stack and its source, even if it is resident or a tray icon.
If the user is already active when the notification pops up, we
won't get an idle watcher because there's no transition from
active to idle or vice versa. Correct this by initializing the
state correctly from XSync.
The designers would like the message-tray to use different styles
depending on whether it is shown in the overview or not, so use
an :overview pseudo class as the top bar.
1) straddling windows get clipped at the monitor boundary
2) we move the bottom monitor and not the primary because that is
where the tray is
3) to stop the wallpaper from the bottom monitor leaking into the
primary, we adjust the clip as the clone animates up/down
https://bugzilla.gnome.org/show_bug.cgi?id=681392
Instead of manually tracking source icon changes, or requiring a manual
call to _setSummaryIcon, add a way to emit a signal when we're guaranteed
the icon has been changed, and then the source actor will automatically
update the icon.
_setSummaryIcon is still available for sources such as the notification
daemon, that require special treatment for the summary icon (to be used
with tray icons)
https://bugzilla.gnome.org/show_bug.cgi?id=680426
We need to make sure the Source is fully constructed before creating
mainIcon, as SourceActor will query the count of the source.
This fixes Telepathy Chats.

It doesn't make sense to have multiple ShellIdleMonitors, since
each has its own GDK filter function, but they all get the same

Rework the count system in Source, to distinguish between the
normal notification count and the count of unseen/unacknowledged
notification. (A notification is considered unacknowledged until
shown, as a banner or inside the summary box pointer).
Includes some code cleanups and a test for multiple notifications
in the same source.
https://bugzilla.gnome.org/show_bug.cgi?id=681143
Reduce padding around persistent sources, and ensure that spacing
around resident notifications is only applied once.
Also, add some padding to the clock.
https://bugzilla.gnome.org/show_bug.cgi?id=681143
Track screen lock status in the message tray, and filter banner
notifications. The message tray is completely hidden when the screen is
locked, but exceptions can be made for individual transient notifications,
such as shell messages and the on screen keyboard.
Non transient sources are shown in the middle of the lock screen. Resident
notifications (such as those from Rhythmbox) are shown in full, while
persistent ones are displayed as icon and message count.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
To allow more than one summary icon actor for a source we split
the model of the source icon (which is iconName, if the default
implementation is used, or a GIcon otherwise) and replace
createNotificationIcon() with a generic createIcon(size). Also,
the actual source actor is split into a separate class, that handles
the notification counter automatically.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
Change visibleInFullscreen to be trackFullscreen. If true, visibility
is fully bound to fullscreen status, if false, no change is made.
This allows to avoid set_skip_paint(), while not messing with
visibility of actors that are sometimes hidden for other reasons.
The flag was reversed because only the panel uses it, so false is
a more useful default.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
The log messages about presence changes unnecessarily cluttered the
notification.
Instead, we now present the presence states (online, offline, away, busy)
with an icon placed right next to the avatar. We also no longer show
notifications on presence changes.

clutter_actor_get_children requires making a temporary GSList from

Don't show non urgent notifications when the primary monitor
is in fullscreen (user watching a movie, having a presentation,

For most subclasses, this is a direct swap -- a lot of the time, the

Two nested scroll views were fighing with each other. The reason isn't
particularly important and has to do with some silliness involving
StAdjustment. The visible effect was that scrolling up and down when
in a summary item view would appear to be glitchy, and sometimes not
work at all.
To fix, make sure that the scroll view we don't care about is disabled
when in a summary mode.
https://bugzilla.gnome.org/show_bug.cgi?id=661615
There have been multiple notifications ever since we had a notification stack
per source, so the idea of one notification being on screen at a time has long
been dead.
https://bugzilla.gnome.org/show_bug.cgi?id=661615
When receiving another message or responding in a new expanded chat
notification that has no prior chat history, the notification moved down
below the edge of the screen instead of expanding up, making part of it
invisible. Avoid this by making sure the notification's position is updated.
https://bugzilla.gnome.org/show_bug.cgi?id=661944
If the user was inactive while a notification was shown, we show the summary
when the user becomes active again. This ensures that we inform the user of
the existance of new notifications that the user might have missed.
When the user comes back from away, the summary is now only shown if it has
new notifications.
https://bugzilla.gnome.org/show_bug.cgi?id=643014
If a widget isn't focusable or none of its children are focusable, then
navigate_focus will return false and the key focus won't be set. We
need to explicitly grab the key focus in this case.
https://bugzilla.gnome.org/show_bug.cgi?id=671001
An actor is removed from its parent after it emits the destroy signal,
so we can't just check if the notification stack has more than one
notification -- we need to check if there's a notification there
that is not the current one.
This was causing spew in the form of:
"this.notificationStack.get_children()[0]._delegate.setIconVisible
is not a function"
Currently it is not possible to trigger the context menu while the
summary notification is opened (and vice versa). To actually trigger
the desired item, the user has to click again, which is annoying
without a good justification, so allow switching directly between
left/right click items.

Instead of leaving the tray covering the whole last pixel row when it's

We must look for the actor under the pointer in the whole message tray and not

https://bugzilla.gnome.org/show_bug.cgi?id=661358
Add "Mute"/"Unmute" option to the right click menu for chats to allow muting conversations
without blocking the sender or disabling all non-urgent notifications. Muting a conversation
prevents the pop up of notifications on new messages from the muted source, while these

https://bugzilla.gnome.org/show_bug.cgi?id=659962
The message tray focus grabbing code sets the stage input
mode to Shell.StageInputMode.FOCUSED when the overview is
not visible. This ensures the stage window's input
region gets reshaped to include the notification chrome,
and so that input events get delivered appropriately to
the notification that grabbed focus.
The message tray code never tries to restore the stage input
mode later. Instead, the code relies on the stage input
mode (and input region) getting reset to
shell.StageInputMode.NORMAL automatically when focus moves
back from the shell chrome to a window in the user's session.
It's not really correct to set the stage input mode based
on the overview's visibility, though. At the login screen,
even though no overview is visible, the stage input mode is
Shell.StageInputMode.FULLSCREEN which is sufficient
for the notification's needs, Furthermore,
Shell.StageInputMode.FOCUSED is insufficient for the login
dialog's needs since the login dialog isn't considered
part of the shell's chrome and won't get included in the
stage input region.
This commit changes the message tray code to only set the
stage input mode if the current stage input mode isn't good enough,
rather than assuming the input mode isn't good enough just because
the overview is hidden.

This ensures that this._clickedSummaryItem is always unset correctly.
Because we disconnect the signals that have _adjustSummaryBoxPointerPosition()
as a callback when unsetting this._clickedSummaryItem, we no longer call
setPosition() on this._summaryBoxPointer after it is hidden. Calling
setPosition() shows the box pointer again, which previously resulted in
an empty box pointer staying behind when a notification associated with
a tray icon was clicked.

With the old pre-boxpointer summary notifications, it sort of made
sense that the summary notification actor was a child of the message

_fixMarkup() was supposed to be ensuring that the markup we passed to
clutter was correct, but it was validating the syntax incorrectly, and
wasn't checking that the markup was valid (or even well-formed). This
is bad because if you pass bad pango markup to
clutter_text_set_markup(), it will g_warn and drop the string on the
floor.
Fix by fixing up the regexps, and then calling Pango.parse_markup() on
the result, and just xml-escaping everything if parse_markup() fails.

As _updateCount has been designed to be overwritable by subclasses,
move the check for _actorDestroyed into _setCount(), to fix the
problem described in commit 5f6ac33d5 in derived types as well.
When trying to update the message count after a summary icon has
been destroyed, the label to display the count is no longer valid
and trying to set its text results in some Clutter warnings.
Remove ShellGlobal's monitor-related methods, and have
Main.layoutManager provide that information instead. Move
Main._relayout() to LayoutManager, and have other objects connect to
the layout manager's 'monitors-changed' signal to know when the screen
geometry has changed.

Theme authors now have the power (and responsibility) of creating fade
effects with the new CSS length property '-st-fade-offset'. A value of
0 disables the effect.
This new CSS approach replaces the current programmatic toggle of

a replacement for the old property.

Currently, the banner text is always located at the right of the
title - we need to swap those around for RTL locales. Rather than
using the locale directly to figure out the ordering, try to
determine the direction of the title label and let it control the
overall direction of the notification - this way, notifications
generally come out right when mixing scripts.

This ensures that we don't show a small black blob fading away
when the user clicks on the notification and it is removed.
Set HIDING state right away in _hideSummaryBoxPointer() so that
it is only called once. Update this._pointerInTray when the tray
is unlocked, so that we are not dependent on escapeTray() being
triggered by 'done-displaying-content' signal.
https://bugzilla.gnome.org/show_bug.cgi?id=645697
Use Meta.later_add() with BEFORE_REDRAW rather than Mainloop.idle_add()
to add the banner body so that the notification body is reliably added
after the first frame is drawn. This is important for notifications that
are expanded right away, such as the summary notifications that
were not shown as banners because the user was in the Busy mode or was
interacting with the summary. Otherwise, these notifications were sometimes
shown with an ellipsized banner and were only getting full content when
they were done animating.
Only add expanded content and signal the change once. Previously, we
used to signal the change numerous times and processing this signal was
holding up processing other things, such as the user moving the mouse
away from the notification so that the notification collapses.

Commit 31b12635d1 fixed links in notifications again, but blocked
clicks on normal labels getting through to the notification. Fix
this, so that both links and dismissing notifications work again.
https://bugzilla.gnome.org/show_bug.cgi?id=645839
The change to make Notification an StButton (06d2c0af, bug 642978)
broke links, because the link actor would ignore the
button-press-event, allowing the notification actor to receive it and
get a pointer grab, and so the link actor would never see the
button-release-event. Fix that by accepting and discarding the
button-press-event.
https://bugzilla.gnome.org/show_bug.cgi?id=645613
If a notification was updated while one of its widgets was focused,
it would lose the grab when that widget was destroyed. Fix that by
moving the focus to a safe place before destroying the old widgets.

We want to minimize focus stealing from the user. If a non-urgent notification
comes in while the user is interacting with the tray, we add it to the tray

urgent notification comes in while the user is interacting with the tray,
we hide the tray and show the urgent notification.

We want to allow the user to scroll through all notifications from
source by using a single scrollbar. We suppress the individual

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

If the user clicks on the title of a trayicon's SummaryItem, forward

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

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

Notification was connecting to button-release-event to decide when to
be dismissed, which caused problems with widgets inside the
notification that reacted to button-press-event but not

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
"presense change", but don't interference with the user's scroll actions
i.e when the user scrolls back to read something don't scroll to the bottom.

Showing the right click menu causes errors when ungrabbing focus in this case.
It will soon be impossible to get to the right click menu anyway when a new

Unset this._expandedSummaryItem if it is the summary item that is being removed.

This patch modifies MessageTray behaviour so that normal (not urgent)
notifications are not shown when the user is Busy (they're sent
immediately to the Summary area). When status is then changed,
notifications still pending are shown again.
Additionally, when status is modified from Idle to anything other than
Busy, the message tray is forced open for 4 seconds, so that summary
icons are visible.

This patch fixes the summary notification reappearing if you click on the
summary item to hide it and hover away. It also ensures that when you click
on any summary item which doesn't correspond to the summary notification
being shown, a new summary notification will replace it right away.
What used to happen is that we'd unset the clicked item in _unlock() that
was called when the focus was ungrabbed because the user clicked outside
of the summary notification, but then would have this._clickedSummaryItem
be null in _onSummaryItemClicked() , and set it to the clicked item all
over again. This patch ensures that we unset the clicked item only when
it is necessary.
We also needed to add the code to call _updateState() again to show a new
summary notification when a previous one was hidden, but
this._clickedSummaryItem was set.
https://bugzilla.gnome.org/show_bug.cgi?id=642005
That way it can be used when other components of the message tray need to
grab focus, such as the summary bubble with multiple notifications or the
summary item's right click menu.
https://bugzilla.gnome.org/show_bug.cgi?id=641810
St.Button 'clicked' signal now has two arguments, and because we are also
passing an action id as an argument to the _onActionInvoked() callback,
we need to have the number of the signal arguments reflected accurately in
the function arguments.

This makes the animation feel more stable and keeps the left-most item expanded
when you move the mouse to the left in the tray.
The following behavior details are implemented by this patch:
- we wait to collapse an expanded item till after the tray is hidden if
we are hiding the tray
- we don't collapse an expanded item if the summary notification associated
with it is being shown, unless a different summary item is hovered over
- we don't consider the mouse hovering over a summary notification as
hovering over the tray, which allows us to collapse an expanded summary
item if it is not associated with the summary notification being shown
https://bugzilla.gnome.org/show_bug.cgi?id=636930
There are multiple code passes that can result in Notification::destroy()
being called, such as a notification being closed by the application
when it exits and the associated source being removed at the same time.
However, we should only emit 'destroy' for the notification and
do the associated work once.
Notification::destroy() now takes 'reason' as an optional argument.
Calling Notification::destroy() directly when connecting to 'destroy'
on Source, as we did before, was inadvertently passing 'source' as an
argument to the function.
https://bugzilla.gnome.org/show_bug.cgi?id=640976
This fixes emitting NotificationClosed for resident notifications
that are clicked, but are not actually destroyed.
This also ensures that we emit NotificationClosed in all cases when
a notification is destroyed, which can happen when:
- a non-resident notification is clicked
- an action is invoked on a non-resident notification
- an application the notification was associated with is focused
- a transient notification is done showing
- a notification was requested to be closed by the application
- a tray icon the notification was associated with is removed

Actors in clutter are supposed to be re-allocated with
Clutter.AllocationFlags.ABSOLUTE_ORIGIN_CHANGED if they move relative
to the screen, even if they don't move relative to their parent.
Currently this does not work correctly for actors inside containers
with non-northwest gravity. This is probably a fixable bug, but
gravity has messed up other things in the past too, so let's just not
use it.

Until recently, the clutter keyboard focus was almost always kept on
the stage, and bits of code that wanted to do stuff with the keyboard
would just watch for key-press-events on the stage. In several places,
the code wasn't even bothering to ensure that the focus was on the
stage, which caused problems with other actors that explicitly grabbed
focus.
A previous fix for this (f21403fd) was to always reset the focus to
the stage after calling pushModal(), but a better fix is to just
actually make use of the keyboard focus everywhere rather than having
everyone try to read events off the stage.
Now pushModal(actor) also does actor.grab_key_focus(), and various
bits of code have been changed to read key events off their own
toplevels rather than off the stage, meaning there's no chance of them
accidentally getting someone else's events.

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.

NotificationDaemon-based notifications have markup in the banner/body,
but Telepathy-based notifications don't. (Eg, an XMPP message

where there should and shouldn't be markup, and use that
appropriately.

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
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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=632590
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.

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.

since it's not a minimum, it's just the width.)

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
Having the summary pop up automatically after a source icon has been
removed is pretty useless ("Hey, there was something interesting going

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.

Previously we were hiding the banner label if the title was too long,
but this causes queue_relayout() warnings. Instead, just set its
opacity to 0.
https://bugzilla.gnome.org/show_bug.cgi?id=629308
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.
https://bugzilla.gnome.org/show_bug.cgi?id=617209
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
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
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.
https://bugzilla.gnome.org/show_bug.cgi?id=625502
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.
https://bugzilla.gnome.org/show_bug.cgi?id=613932
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.
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.
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.
