The current user status menu allow to set the session status,
which also influences the IM status when signed in with
mission-control. However, the way it is presented to the user
makes it hard to figure out how the statuses interact or that
there are two distinct status in the first place.
Therefore, use a separate control for each status, and update the
overall look to match gnome-contacts.
https://bugzilla.gnome.org/show_bug.cgi?id=652837
Given that our menus contain at most two columns, all switch widgets
in menus end up in the last columns, and thus aligned with the right
menu edge.
However, the updated user status menu will contain a section which
ignores the menu's column layout, so the switch might end up in
the middle of the menu if the overall width is determined by said
section.
At least for now, we always want the switch to align with the end,
so just expand switch menu items rather than adding an option.
https://bugzilla.gnome.org/show_bug.cgi?id=652837
Introduce a new menu widget, which displays the active item from
a set of options, and pops up a child menu to allow changing the
active item when activated.
https://bugzilla.gnome.org/show_bug.cgi?id=652837
Allow opening a popup menu from another menu. While the child menu
is open, events on the parent menu are blocked. The parent menu
is kept open when the child menu is closed; the child menu on the
other hand is closed with the parent, e.g. when the focus moves
to another toplevel menu.
This feature will be used to implement combo box menu items.
https://bugzilla.gnome.org/show_bug.cgi?id=652837
We haven't actually been calling the top-right menu "status menu" for
quite some time, so use the upcoming code changes as an excuse for
renaming it to "user menu".
Doing this rather than overdrawing a black rectangle saves us
(pixels in screen) * 8 bytes of memory bandwidth for every frame we draw going
into the overview.
It also allows us to dim the background on non-primary monitors making the
overall overview appearance consistent across all monitors.
https://bugzilla.gnome.org/show_bug.cgi?id=656433
Instances of this class share a single CoglTexture behind the scenes which
allows us to show the background with different rendering options without
duplicating the texture data.
https://bugzilla.gnome.org/show_bug.cgi?id=656433
This commit adds GDM session support.
It provides a user list that talks to GDM,
handles authentication via PAM, etc.
It doesn't currently support fingerprint readers
and smartcards.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
The shell has a number of things that are only relevant for
logged in users (e.g. calendar events, telepathy integration, a
user menu, etc).
This commit moves those user session specific bits into their
own functions in preparation for making the shell code ready
for use at login time.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
Right now the panel code makes the left corner sync up with the
activities button and the right corner sync up with the user menu.
This is fine as long as we have an activities button and a user menu.
The login screen won't have those things, though.
This commit changes the panel corner code to try to figure out which
interface element is the most appropriate to sync up with based on
its position in the panel.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
Images are part of the notification spec, so we should support them.
Marina Zhurakhinskaya provided some code for getting the layout right
for this patch.
https://bugzilla.gnome.org/show_bug.cgi?id=621009
Have LayoutManager automatically deal with sizing and positioning
boxes for the panel and messageTray relative to the monitors.
Also, now that LayoutManager knows exactly where and how tall the
panel and tray are, have it manage the pointer barriers as well.
https://bugzilla.gnome.org/show_bug.cgi?id=612662
In order for transformation animations to look good, they need to be
incremental and have some order to them (e.g., fade out hidden items,
then shrink to close the void left over).
Chaining animations in this way can be error prone and wordy using just
Tweener callbacks.
This commit adds a new set of classes to help:
- Task. encapsulates schedulable work to be run in a specific scope.
- ConsecutiveBatch. runs a series of tasks in order and completes
when the last in the series finishes.
- ConcurrentBatch. runs a set of tasks at the same time and completes
when the last to finish completes.
- Hold. prevents a batch from completing the pending task until
the hold is released.
The tasks associated with a batch are specified in a list at batch
construction time as either task objects or plain functions.
Batches are task objects, themselves, so they can be nested.
For now, these APIs are temporarily getting staged in a gdm/ specific
subdirectory so they will be available for use by GDM. They aren't
specific to GDM, or even to doing animations, though, so the API may eventually
move in some form or another to a more general location. Alternatively, the
APIs may ultimately get dropped entirely and replaced by something else.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
A modal dialog in the shell blocks anything but that dialog from
receiving user input. Applications within the session and other
parts of UI are rendered non-reactive.
When GDM gets changed to use the shell for its greeter, the user
list will be presented as a shell dialog. That dialog shouldn't
block access to the panel menus, etc.
This commit adds a shellReactive property that makes the ModalDialog
class continue to block access to applications, but allow the user
to interact with the shell itself.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
The control-center contains user-pertinent settings
panels. These panels don't make sense to show outside
of a user's session, so hide them for session types other
than SessionType.USER.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
We're not going to want an overview at the login screen,
but a lot of code in the shell depends on the overview
existing.
This commit adds a new isDummy constructor property to
allow creating the overview as a non-functional, stub object
that doesn't do anything visible.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
The dash object is currently exposed as a public object.
It's only used outside of the overview for the dash object's
iconSize property though.
This commit makes the dash object private and proxies the dash
iconSize property to the overview.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
Right now, when a user clicks on the panel clock, a menu pops up with a
calendar and a list of events from the user's schedule. The list of
events only makes sense from within a user's session, however.
As part of the prep work for making the shell a platform for the login
screen, this commit makes the events list optional.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
The theme currently hard codes the minimum size of the calendar
menu to make sure there's a designated area for events
(even if there isn't anything currently scheduled).
A side-effect of the hard coded minimum width is that
if the events area is hidden, the menu ends up much
bigger than the calendar. We don't currently ever hide
the events area, but we will in the future.
This commit moves the min-width restriction from the menu
specifically to the events area.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
The chrome layer contains the user interface elements (e.g.,
the panel) that disappear when fullscreen windows get displayed.
Panel menus are currently put in the chrome layer, but don't need
to be, since they are only displayed when the user is interacting
with the shell and not a fullscreen application.
Putting panel menus in the chrome layer does mean they will get
stacked below shell interface elements that aren't in the chrome layer,
though.
This commit changes panel menus to be on the same layer as most other
shell elements, so they get properly stacked above those elements.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
Right now, if buttons get set on a dialog after it is mapped,
they just pop in instantly.
We shouldn't have any harsh transitions like that, though.
This commit changes the buttons to quickly fade in, instead.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
All the system status menus in the panel offer a
menu item to jump to a relevant part of the
control-center.
This means each status icon has the same, or nearly the
same bit of code to:
- Add a new "action" menu item and listen for its activation.
- Hide the overview if it's showing when the menu item is activated
- Find the relevant control-center panel from its desktop file
- Launch the control-center to the relevant panel
This commit consolidates all those details in a new method,
addSettingsAction. This refactoring reduces code duplication and
slight inconsistencies in the code resulting from that duplication.
It will also make it easier in subsequent commits to hide settings menu
items when the shell is used in the login screen.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
A separator only makes sense if there are items on both
sides of it. There is quite a lot of code written
throughout the shell that manages the process of showing
and hiding separators as the items around those separators
change.
This commit drops all that code in favor of changes to the menu
implementation to dynamically hide or show separators as
appropriate, so the callers don't have to deal with it.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
Wireless and 3g dialog code has moved to gnome-control-center, so
we can stop calling out to nm-applet. Also, we can now enable the
notifications provided by the shell and kill a bit of code about
auth that is not actually needed.
https://bugzilla.gnome.org/show_bug.cgi?id=650244
Using the new ShellNetworkAgent, show a system modal dialog
(similar to the PolicyKit one) when NetworkManager needs secrets
for connecting to wireless.
https://bugzilla.gnome.org/show_bug.cgi?id=650244
The order of indicators depends on the order of calls to
Panel.addToStatusArea. To have it consistent across enabling and
disabling of extensions, we need to place the core ones first.
https://bugzilla.gnome.org/show_bug.cgi?id=653205
This way all standard indicators have a shell implementation
provided, which prevents issues with extensions enabling/disabling
(in particular with xrandr-indicator)
https://bugzilla.gnome.org/show_bug.cgi?id=653205
Extensions often want to add items to the system status area, so it
is useful to add a convenience API for it. Also, we now allow
for cleaner destruction of panel objects, by just calling destroy()
on it.
Based on a patch by Jasper St. Pierre.
https://bugzilla.gnome.org/show_bug.cgi?id=653205
The "id" variable was being sporadically reset to null, and as far as
Florian and I could determine, this is actually a Spidermonkey bug.
The issue has something to do with:
1) use of "let" for the variable
2) Nesting a dynamic closure inside of a for() loop
Work around it here for now - I tried to create a minimized test case
to hand to the Spidermonkey developers, but failed. A big part of
the problem is it's only sporadically reproducible.
Direction containers group all contiguous messages in the same direction into
their own parent container, allowing for smarter styling of similar messages.
https://bugzilla.gnome.org/show_bug.cgi?id=640271
This adds a new DBus method: InstallExtensionRemote(uuid : s, url : s)
Pass it the UUID of an extension and the URL of a manifest file: the same as a
metadata.json, but with a special key, '__installer', which is an HTTP location
that points to an zip file containing the extension. The Shell will download
and use it to install the extension. In the future, the manifest file may be
used to automatically detect and install updates.
https://bugzilla.gnome.org/show_bug.cgi?id=654770
The two similar keys were hard to manipulate to have specific effects, so just
remove one. Now there is an *explicit* whitelist: all extensions must be in the
'enabled-extensions' for them to be loaded.
https://bugzilla.gnome.org/show_bug.cgi?id=654770
It's generally more useful to see when a person sent a message instead of when
we received it. Also, a recent change in Telepathy made the received timestamp
be 0 for messages we send.
https://bugzilla.gnome.org/show_bug.cgi?id=640271
Adds methods to shell_global to allow taking screenshots
save the result into a specified png image.
It exposes three methods via shellDBus applications like
gnome-screenshot:
*) Screenshot (screenshots the whole screen)
*) ScreenshotWindow (screenshots the focused window)
*) ScreenshotArea (screenshots a specific area)
https://bugzilla.gnome.org/show_bug.cgi?id=652952
It is not possible to connect to hidden access points without
knowing the SSID, and it should be done using the control center
panel and the appropriate dialog. At the same time, this should
fix some warnings from libnm-glib and dbus-glib.
https://bugzilla.gnome.org/show_bug.cgi?id=646454
The shell should only notify in case no other client handles the message.
Empathy will ack the message if focused, so we don't want to step on its
toes.
Use the existing setting
org.gnome.desktop.default-applications.office.calendar.exec
as calendar application instead of the hard-coded evolution. Evolution
is still the fallback if that setting is cleared (it defaults to
evolution).
https://bugzilla.gnome.org/show_bug.cgi?id=651190
Since almost all of the callers of shell_app_activate were using the
default workspace (by passing -1), remove that parameter.
Add a new shell_app_activate_full() API which takes a workspace as
well as a timestamp; previously we might have been ignoring event
timestamps from elsewhere.
https://bugzilla.gnome.org/show_bug.cgi?id=648149
This dramatically thins down and sanitizes the application code.
The ShellAppSystem changes in a number of ways:
* Preferences are special cased more explicitly; they aren't apps,
they're shortcuts for an app), and we don't have many of them, so
don't need e.g. the optimizations in ShellAppSystem for searching.
* get_app() changes to lookup_app() and returns null if an app isn't
found. The semantics where it tried to find the .desktop file
if we didn't know about it were just broken; I am pretty sure no
caller needs this, and if they do we'll fix them.
* ShellAppSystem maintains two indexes on apps (by desktop file id
and by GMenuTreeEntry), but is no longer in the business of
dealing with GMenuTree as far as hierarchy and categories go. That
is moved up into js/ui/appDisplay.js. Actually, it flattens both
apps and settings.
Also, ShellWindowTracker is now the sole reference-owner for
window-backed apps. We still do the weird "window:0x1234beef" id
for these apps, but a reference is not stored in ShellAppSystem.
The js/ui/appDisplay.js code is rewritten, and sucks a lot less.
Variable names are clearer:
_apps -> _appIcons
_filterApp -> _visibleApps
_filters -> _categoryBox
Similarly for function names. We no longer call (for every app) a
recursive lookup in GMenuTree to see if it's in a particular section
on every category switch; it's all cached.
NOTE - this intentionally reverts the incremental loading code from
commit 7813c5b93f. It's fast enough
here without that.
https://bugzilla.gnome.org/show_bug.cgi?id=648149
Add a helper function (mostly copied from gtkcalendar.c) for getting
the first week day for the current locale, using nl_langinfo if
available and falling back to the GTK+ gettext fallback otherwise.
Use that function in the calendar, so that the LC_TIME setting is
used if possible.
https://bugzilla.gnome.org/show_bug.cgi?id=649078
Instead, create three ripples and keep tweening them. This gives a dramatic
speedup when entering the overview, but means that we can't have the same animation
running twice. In this case, we "reset" the currently running ripple animation, but
it is hard to notice unless looking for it.
https://bugzilla.gnome.org/show_bug.cgi?id=656125
Extension developers may be confused about why their extensions aren't working:
the LookingGlass isn't a very obvious place, or even which errors are theirs.
To remedy this, save all errors per-UUID which allows them to be retrieved
later.
https://bugzilla.gnome.org/show_bug.cgi?id=654770
Add ShellVersion, designed for detecting OUT_OF_DATE extensions so they can't
be installed, as well as ApiVersion, designed for backwards-compatibility with
the SweetTooth web-app, which must support all shell versions.
https://bugzilla.gnome.org/show_bug.cgi?id=654770
GetExtensionInfo() takes a UUID and returns a JSON object with information
about that extension including their metadata, path and current state.
ListExtensions() takes no arguments and returns a JSON object mapping UUIDs
to the same information objects described above.
https://bugzilla.gnome.org/show_bug.cgi?id=654770
As an effort to prevent a string freeze to land timestamps on 3.0, we reused
translations for the calendar. Now that the string freeze is long gone, make
some proper strings.
https://bugzilla.gnome.org/show_bug.cgi?id=640271
The notification spec supports the concept of a 'default' action:
"The default action (usually invoked my clicking the notification)
should have a key named "default". The name can be anything, though
implementations are free not to display it."
Support this by invoking the 'default' action rather than a emitting
the 'clicked' signal when clicking notifications which specifie a
default action.
Also don't add an action button for the default action.
https://bugzilla.gnome.org/show_bug.cgi?id=655818
LayoutManager and Chrome are already somewhat intertwined and will be
becoming more so. As a first step in merging them, move the Chrome
object into layout.js (with no other code changes).
https://bugzilla.gnome.org/show_bug.cgi?id=655813
Looking Glass is supposed to slide out from underneath the panel.
Rather than fiddling with Main.chrome.actor directly, just add the lg
actor to the chrome, and fix its stacking there.
https://bugzilla.gnome.org/show_bug.cgi?id=655813
With the old pre-boxpointer summary notifications, it sort of made
sense that the summary notification actor was a child of the message
tray. But there's no reason for that now, and in fact, it ends up
requiring special cases in some places since hovering over the summary
notification counts as hovering over the tray. So, fix this.
https://bugzilla.gnome.org/show_bug.cgi?id=655813
Rather than having the panel corners as independent bits of chrome and
manually syncing their positions, put them inside the panel actor, and
update the panel's allocation code to position them correctly.
https://bugzilla.gnome.org/show_bug.cgi?id=655813
The buttons should have a glassy transparent look. Also, they should not
be as tall, should light up on hover, and their labels should be white
in order to stand out. Making the labels solid white requires removing the
transparency set in modalDialog.js. Also, add a separate color setting
for the dialog as a whole - this avoids having a white icon.
https://bugzilla.gnome.org/show_bug.cgi?id=655428
The specs call for a 2 pixel gap between the panel and its menus,
though we need to specify this as 4 pixels, since it's relative to the
bottom of the icon/title, not the bottom of the panel (up until now,
the point of the menu arrow was actually overlapping the menu's
highlight underline).
Also, move the gap specification into the CSS, since it makes more
sense there.
https://bugzilla.gnome.org/show_bug.cgi?id=655627
Since this link in the keyboard menu points to Region and Language
Settings in System Settings, we should be consistent and use that
term instead of "Localization Settings"
Also, this removes ellipsis from "Show Keyboard Layout" since it
doesn't require further input.
https://bugzilla.gnome.org/show_bug.cgi?id=652984
The current check for fullscreen windows ignores the window's
minimization state, so that chrome which is hidden in fullscreen
will always hide if the window on top of the window stack is
fullscreen, even if it is actually minimized.
Instead, skip minimized windows when looking for fullscreen windows.
https://bugzilla.gnome.org/show_bug.cgi?id=655446
_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.
https://bugzilla.gnome.org/show_bug.cgi?id=650298
Keeping the volume menu open after setting the desired volume isn't that
useful and forces a second click (or an Esc press) to dismiss it. Allow for

https://bugzilla.gnome.org/show_bug.cgi?id=649586
Move the HotCorner class from panel to layout, and make the panel
manage its own HotCorner.
Stick the panel's HotCorner into the Activities button actor (rather
than separately floating above it), so that hover tracking on the
button works properly without needing hacks in HotCorner.
https://bugzilla.gnome.org/show_bug.cgi?id=645759
The fact that everything in the top bar except the activities button
was a menu made various things difficult. Simplify this by making the
activities button be a menu too, but just hack it up a bit so that the
menu associated with the button never actually appears.
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=645759 (Clicking on
Activities with menu up leaves a funny state) and its semi-dup 641253
(panel keynav between Activities and menus is quirky).
visibleInOverview chrome was visible even when the screensaver was
active. Although we may eventually need visibleInScreenSaver, that
should be a separate flag.
Fix this by tracking the screensaver active state, and hiding the chrome
when the screensaver is active.
https://bugzilla.gnome.org/show_bug.cgi?id=654550
Fix the signal handling; you can't use this.connect('ActiveChanged')
to connect to a D-Bus signal after replacing the signal methods with
the lang.signals versions. Just leave it using the D-Bus signal names,
just like it uses the D-Bus method names.
Also, remove the "_" from "_screenSaverActive", to match what
AutomountManager checks for, and remove getActive(), since it's not
needed.
https://bugzilla.gnome.org/show_bug.cgi?id=654550
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.
If the resident source is destroyed, it should be recreated
immediately, so that it is available when another volume is
mounted. However, we only connect to the 'destroy' signal
on the original source, not on newly created ones. As a result,
the resident source only works twice, after that it shows up
without icon and an empty notification.
Fix by always connecting to the source's 'destroy' signal.
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.
Basically do what NautilusPlacesSidebar does with the drive/volume/mount
eject/unmount/stop priorities.
We follow this pattern:
- always prefer Safely Remove if available (i.e. drive.stop())
- fallback to ejecting the mount/volume/drive if that's not possible
- finally, fallback to unmounting the mount if even eject is not
available
This also means we don't care about the distinction between
Stop/Eject/Unmount at this level. Disk Utility (or Nautilus) are
available for those who want that degree of control, but the common case
here should do the most useful action without presenting the choice.
https://bugzilla.gnome.org/show_bug.cgi?id=653520
Ideally, this would be an entirely-JS implementation, but we have a
couple of issues with gjs and gobject-introspection to work around, so
we need a ShellMountOperation class for the time being.
This first commit implements the show-processes dialog, with a system
modal style very similar to the EndSession dialog.

If possible, use the results from the sniffer process in order to have
less-generic alternatives to the file manager in the proposed autorun
choices.

Autorun preferences can be fine-tweaked at the content-type level from
the System Settings 'Removable Media' panel.
Use those settings to figure out the default action for newly-mounted
mounts.
https://bugzilla.gnome.org/show_bug.cgi?id=653520
The AutomountManager class is the low-level counterpart of the
previously introduced AutorunManager, and takes care of extracting the
list of valid mounts from a GVolume or a GDrive and mounting them,
provided a number of conditions and requirements are met.
AutomountManager also keeps track of the current session availability
(using the ConsoleKit and gnome-screensaver DBus interfaces) and
inhibits mounting if the current session is locked, or another session
is in use instead.
https://bugzilla.gnome.org/show_bug.cgi?id=653520
AutorunManager is a class that takes care of displaying and managing
notifications and UI for storage devices.
When a mount appears and a number of conditions are satisified, a
transient notification will be displayed to immediately interact with
the device. AutorunTransientDispatcher is the object that takes care of
showing/hiding the notification sources as devices appear/disappear.
Likewise, current mounts are kept in a list and presented within a
list in a resident notification, handled by AutorunResidentSource.

On error, we tried to kill and respawn gnome-power-manager, but

We don't want sources that are no longer associated with a running application
to stick around in the message tray.
Message tray sources were removed when the associated application’s state
changed to Shell.AppState.STOPPED . This caused sources for applications
that were still running, but did not have any open windows to be removed.
Instead, we should use the notification’s sender removal from DBus as an

Commit 64b2b4a7d4 changed the monitor layout handling, resulting
in some layout errors due to a subtle change in memory handling:
when zooming a window in the overview, the available zoom area is
calculated by subtracting the panel height from the primary monitor
area. This area used to be a copy of the monitor rect, but as now
the rect itself is returned, zooming a window on the primary monitor
repeatedly modifies the monitor rect, leading to layout errors in
various parts of the shell.
Fix by using a copy when calculating the available zoom area.

Use a longer fade-in time, but with an inout transition, so that the

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.
