It seems this behavior at one time was intentional, but I (along with
the designers) think it looks ugly having the menu having its insides
shrinking and shifting around while fading out of existence.
There's two cases where we currently explicitly try to animate the
submenu closed -- when an item is clicked inside the submenu, and
when the toplevel closes. This removes both of those.
The user expectation is that submenus will be closed the next time the
toplevel is open even if they were open before, so force submenus closed
when the toplevel finishes fading out, without any animation.
https://bugzilla.gnome.org/show_bug.cgi?id=702539
As the aggregate menu will be built out of sections from each
of the menus, we need to ensure that activating an item in one
of these sections can close the main menu, even when it is not
a menu item. The new API also needs to be flexible enough to
ensure that animations can be controlled, like the buttons that
lock the screen or launch a new session.
Port the user menu to use this new API as well.
https://bugzilla.gnome.org/show_bug.cgi?id=702539
While the default style works well will a solid handle, using both

Since commit c84dc6254d, popup menus are closed automatically
when another menu opens (to catch the case where a menu is opened
by keyboard shortcut, which wasn't handled before). However in the
case of child menus, both child and parent are expected to be visible,
so handle this case explicitly.
https://bugzilla.gnome.org/show_bug.cgi?id=699678
We already do this when navigating between menus via mouse or
keynav, but miss cases where a menu is opened by other means,
for instance via a keyboard shortcut.
https://bugzilla.gnome.org/show_bug.cgi?id=686756
Currently all keybindings are disabled while some popup menu is open.
However some keybindings may still be useful in some cases, so expose
GrabHelper's modal params parameter to allow specifying a keybinding
mode for particular menus.
https://bugzilla.gnome.org/show_bug.cgi?id=698938
This simplifies the code required to build remote menus and
put all the items in the right place, and makes us share our

This makes it easy to replace the dot with another label in the future.

Due to limitations and bugs in SpiderMonkey's GC, wrapper objects
for cairo contexts and similar may not get cleaned up immediately
after repainting, leading to leaking memory. Explicitly disposing
of such objects after they're not needed can clean up large portions
of memory for cairo surfaces.

Allow users to smoothly scroll on the volume indicator icon
to adjust the volume. Do this by simply passing the scroll
event to the slider inside the menu.
https://bugzilla.gnome.org/show_bug.cgi?id=687573
BoxPointer's API changed to take a BoxPointer.PopupAnimation
enumeration value, but the code was accidentally replaced with
older code when porting the PopupMenuManager code to GrabHelper.
https://bugzilla.gnome.org/show_bug.cgi?id=689954
"toggle" is used when clicking on the source actor. As we don't
actually have a menu, we don't want to actually take any grabs
through the menu system, so make it a no-op rather than have it
toggle the menu state.
https://bugzilla.gnome.org/show_bug.cgi?id=689954
Currently close() is a no-op when the menu has already been closed.
However, repeated calls could pass different animation parameters.
For instance in the user menu, we try to hide the menu immediately
before locking the screen, to avoid the popup jumping across the
screen while fading out - as we do this from the corresponding
item's activate handler, the closing is still animated if the menu's
own handler (which requests a full animation) is run first.
Fix this by changing close() to overwrite ongoing animations before
bailing out early.
https://bugzilla.gnome.org/show_bug.cgi?id=686484
With the recent session mode changes, the visibility of settings
items is now only set on sessionMode::updated - while the signal
is emitted when the session mode is initialized, settings items
that are added after that are visible regardless of the allowSettings
setting until the next sessionMode::updated signal is received.
Fix this by explicitly setting the initial visibility of settings
items.
https://bugzilla.gnome.org/show_bug.cgi?id=684473
The selector for insensitive popup menu items was wrong (a PopupMenuItem is
a ShellGenericContainer, not a StButton). Fixing it showed that previous
:insensitive tracking was manual for a reason: we have many items that are
not reactive, but don't want the insensitive styling (for example those in
the battery menu).
Fix it by adding a new style-class, popup-inactive-menu-item, that is added
to all new PopupMenuItems that are not activatable.
https://bugzilla.gnome.org/show_bug.cgi?id=683988
Hidden children are currently ignored in width requests; in the
case of submenu items, this results in abrupt width changes of
open menus when the corresponding SubMenuMenuItem is toggled.
To fix, only ignore SubMenu children when the corresponding
SubMenuMenuItem is hidden as well.
https://bugzilla.gnome.org/show_bug.cgi?id=683485
The special padding rules for submenu items currently ensure that
content aligns properly when the scrollbar is shown. While they
work nicely for the network menu, it looks odd for non-scrolled
submenus, so make this case explicit by introducing a :scrolled
pseudo class and adjust the style rules to use it.
https://bugzilla.gnome.org/show_bug.cgi?id=683009
Since we eventually want to add a system for changing the top panel
contents depending on the current state of the shell, let's use the
"session mode" feature for this, and add a mechanism for updating the
session mode at runtime. Add support for every key besides the two
functional keys, and make all the components update automatically when the
session mode is changed. Add a new lock-screen mode, and make the lock
screen change to this when locked.
https://bugzilla.gnome.org/show_bug.cgi?id=683156
PopupMenuBase relies on open-state-changed to update the separator
visibility, but PopupMenuSection were only emitting when the parent

StScrollBar was intercepting motion events by using captured-event on

In some cases can_focus value is taken directly as

Track locked status and use it to provide a reduced version of
the panel in the locked screen. Accessibility, input sources and
volume menus are preserved, without the link to the control center.
Network, battery and user menu are reduced to pure indicators,
with no menu.
This is similar to the design but not exactly, because designers
in IRC said that network needs more analysis before exposing, and
because the design didn't account for a11y and IM (so the one menu
metaphor is not really appropriate).
https://bugzilla.gnome.org/show_bug.cgi?id=619955
clutter_actor_get_children requires making a temporary GSList from

For simple cases like the number of children, use clutter_actor_get_n_children.

Do not overflow currentItems array. If the Menu section is filled
via model items-changed callback the position in the model passed to
the RemoteMenu _modelChanged can be a to be added asynchronously
action-added. Thus the item does not yet exists in the currentItems.

Rather than accessing global.session_type / global.session_mode
all over the place, delegate mode information to a dedicated
sessionMode object. While not very useful for now, we will replace
checks for a particular mode with checks for particular properties
that sessionMode defines based on global.session_mode.
https://bugzilla.gnome.org/show_bug.cgi?id=676156
According to the GIO docs, sections can have labels too. We support
them by inserting a non reactive menu item at the beginning of the
section. This item is specially flagged to be ignored while processing
changed signals from the model (since it does not correspond to any
model item)
https://bugzilla.gnome.org/show_bug.cgi?id=666681
After an item is destroyed, all its signals were disconnected,
except for 'destroy' itself. This could lead to exceptions, if

GDBusActionGroup api has changed again, adapt to that.

The Lang module in gjs has recently gained a small yet powerful

ComboBoxMenuItems use ClutterClones to reconstruct the active item
in the associated ComboMenu, so pseudo class changes due to state
changes of the ComboBoxMenuItem don't have the intended effect
(since the actual style information is taken from the associated
ComboBoxMenu item).
As a fix, propagate relevant pseudo class changes to the active
ComboBoxMenu item.
https://bugzilla.gnome.org/show_bug.cgi?id=662799
ComboBoxMenuItems use ClutterClones to reconstruct the active item
in the associated ComboMenu to not impose a particular MenuItem type
in the menu. However, this results in style changes (for instance
those triggered by icon-theme or text-scaling-factor changes) of
the ComboBoxMenuItem not having a visual effect until the ComboBoxMenu
is shown.
As a fix, force a style update on the ComboBoxMenu when the item's
style changes.
https://bugzilla.gnome.org/show_bug.cgi?id=662799
SubMenuMenuItems close automatically with their parent, however
closing fails when the parent item is a MenuSection, as those
currently ignore any open()/close() requests.
At some minimal handling by emitting the 'open-state-changed' signal,
so children like SubMenuMenuItems work as expected.

Currently BoxPointer/Menus always point to the center of the

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.

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

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.

The control-center contains user-pertinent settings
panels. These panels don't make sense to show outside

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
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.

Right now, the network menu will overflow the screen if More...
is selected with many access points. As a short-term workaround
for this, add a scrollbar for submenus of panel dropdown menus
if they would cause the toplevel menu to overflow the screen.
- Put the actors in a PopupSubMenu in a StScrollView so we get
a scrollbar if the allocated space is smaller than the height
of the menu. Expand animation is turned off in the scrolled case
to avoid weirdness.
- When we pop up a panel menu, set a max-height style property
on the panel menu to limit it to the height of the screen.
- Hack event handling while the scrollbar is dragged to make
the scrollbar work properly.

It can be useful to avoid sending enter/leave events to the source actor

In the mockups the slider does not have an uniform color but uses

PopupMenuManager was pretending that it knew nothing about the menu's
sourceActors, while also trying to handle keynav between them. This
was a big mess, and resulted in bugs in navigation between panel menus

to add keynav to the dash (whose menu sources are arranged vertically
rather than horizontally).
Fix this up by moving the panel-specific parts to PanelMenuButton

Complex popup menus require the ability to manager sequences of items
as "sections", to which you can add and and remove items, as well
as hide and show.
PopupMenuSection does exactly that, leveraging the existing machinery

Also, make getMenuItems() private, since it is used for different things

Also, redo the menu/menuitem padding so that all the horizontal

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

PopupImageMenuItem, then always show an icon, and just use regular
PopupMenuItems for the items that don't have icons in the current
design.

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.)

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.

Icons can be loaded as St.Icon.SYMBOLIC, FULLCOLOR, APPLICATION or

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

This patch adds the method "removeMenu" to PopupMenuManager, to allow
