StIcon will skip loading the texture when its theme node is unset (which
may happen on style changes while the widget is hidden). While our size
request to compute the dash icon size will create the icon's theme node
if necessary (and of all its parents), a missing texture can still throw
off our computation.
Make sure this doesn't happen by ensuring the icon's style first, so the
texture is updated in response to StWidget::style-changed if necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=745649
When adjusting dash icon sizes, we compute the icon padding by subtracting
the configured icon size from the first icon actor's preferred size. To
make sure that the preferred size correctly corresponds to the current
dash icon size even while the icon is animating, we enforce the size
before the size request. For that we used to temporarily manipulate
the icon texture size directly, but commit e92d204d42 cleaned this
up to use the setIconSize() method instead.
This does not work however, as the icon actor's iconSize property will
always match the dash iconSize property, making the method a noop. So
go back to the original approach of enforcing the texture size to make
sure we always base our computations on correct values.

The overview has a longer life-time than dash items, so we are
leaking a signal connection each time an item is destroyed.

Because there's nothing (in single-monitor setups) that could
take the drop in this case.
* js/ui/appDisplay.js:
AllView._loadApps(), FrequentView._loadApps(): Pass
an isDraggable parameter when creating the AppIcons,
depending on whether the favorite-apps key is locked.
AppIcon._init(): Check for isDraggable in the params and
do not create _draggable if it was specified, to prevent a
drag from starting.
AppIcon.popupMenu(): Check _draggable before trying to call
fakeRelease on it.
* js/ui/dash.js: Dash._createAppItem(): Check AppIcon._draggable
before trying to connect to its signals.

In a lockdown scenario, where the favorite-apps GSettings key is not
writable, hide the menu items for adding and removing favorites from the
dash menu. Additionally, reject drops to the dash for DND.
https://bugzilla.gnome.org/show_bug.cgi?id=741325
When the dash does not contain any applications (either favorites
or running), it is currently impossable to add a favorite via DND.
Grow the dash slightly in that case to provide a drop target.
https://bugzilla.gnome.org/show_bug.cgi?id=684618
We currently only keep track of old placeholders when moving past
the dragged app's current favorite position, as this is the only
case where we need to worry about jitter. Still, moving it into
_clearDragPlaceholder() allows us to consolidate code paths, which
is a good thing ...
https://bugzilla.gnome.org/show_bug.cgi?id=684618
The function currently only resets the placeholder position if
there is a placeholder; this is not necessarily true, as the
placeholder may be reset outside _clearDragPlaceholder().
If this happens, the placeholder will temporarily stop working
for the "old" position (and permanently if it's the only position).
Just reset the position unconditionally.
https://bugzilla.gnome.org/show_bug.cgi?id=684618
animateIn and animateOut should not reset the scale, otherwise
extra animate calls (which are possible because the diff algorithm
in _redisplay is not optimal) cause unneeded movement.
Therefore, create new items hidden, and have the creator call
animateIn or set the scale/opacity properties manually.
adjustIconSize must be changed to always set the icon size temporarily,
otherwise the first time it computes the icon size with 0 scale.
https://bugzilla.gnome.org/show_bug.cgi?id=690643
The DashActor will known to allocate the show apps button only if the
icon size is (temporarily) too big for the containing box, therefore
it should request just that as the minimum size.
This solves a glitch that happened when removing a favorite and at the
same time causing the dash to expand.
https://bugzilla.gnome.org/show_bug.cgi?id=690643
AppIcon is just a tiny wrapper around BaseIcon, which does not add
anything over using BaseIcon directly, so merge its code with
AppWellIcon. As the concept of the "app well" has not been used
since well before 3.0, use AppIcon as name for the merged class.
https://bugzilla.gnome.org/show_bug.cgi?id=694192
When updating the dash, we already avoid all animations while the
overview is hidden. However, as we are using Main.queueDeferredWork(),
updates may be deferred up to ~20 seconds while the overview is hidden.
If the overview is entered before a queued update has taken place, it
will be run immediately on map - as the overview is visible by then,
this means animating any outstanding changes.
Work around this by skipping animations during overview transitions as
well.
https://bugzilla.gnome.org/show_bug.cgi?id=686530
When in the overview, if you move the mouse cursor over one of the
application launchers in the dash, all the unrelated windows are dimmed
both both in the window view and in the workspace view.
It helps to easily understand whether or not there are already opened
windows for this application, and where they are. It can also help in
differentiating the windows in the overview (sometimes the thumbnails
aren't precise enough to easily know which thumbnail belongs to which
application).
https://bugzilla.gnome.org/show_bug.cgi?id=657315
This has also the benefit of getting the application even if it can not
be retrieved through AppSystem, which can happen if the runtime WMClass
does not match the one of the desktop file.
This especially looked wrong with the following commits related to the
bug.
https://bugzilla.gnome.org/show_bug.cgi?id=657315
We simply hide the label when the popup is opened instead of relying
on the popup state when the hover state change.
To do this we replace the flag isMenuUp by a 'menu-state-changed' signal
on the AppWellIcon. This simplifies the dash label visibility handling
code that need additional changes for the bug.
https://bugzilla.gnome.org/show_bug.cgi?id=657315
After some changes, the tooltip label at the dash is not available
until it is visually shown. As this is not anymore a reliable
source of accessible name, we just set the accessible name
with the string used on that label.
https://bugzilla.gnome.org/show_bug.cgi?id=686583
Currently the label for the show-apps button is only updated during
drag operations, so after an item is successfully dropped on the
button, the label will still read "Remove from Favorites".
Fix this by resetting the label on drag-end.
https://bugzilla.gnome.org/show_bug.cgi?id=684627
Having the tooltip change when it's visible looks strange and glitchy.
This also makes sure that "Remove from Favorites" doesn't change, even
when the user removes their mouse cursor from it.
https://bugzilla.gnome.org/show_bug.cgi?id=685313
When Florian landed the new dash container to show the all apps button
always, he got the math wrong -- he forgot to add padding around the
container, and used the height of the box to calculate a y2 position,
rather than the y2 position of the box.
https://bugzilla.gnome.org/show_bug.cgi?id=684619
When the dash contains more icons than fit at the minimum icon size,
icons are cut off at the end. This means that the show-apps button
will be the first to disappear, which is problematic given it's the
sole access point for other applications (for those that refuse to
use search at least).
Fix by using a dedicated widget for the dash actor, so that in case
of underallocation only icons above the show-apps button end up being
cut off.
https://bugzilla.gnome.org/show_bug.cgi?id=683340
We pass the dash’s showApps button to the viewSelector, and we connect it
to the showing and hiding of the appsView. This is necessary because there
are different mechanisms for switching the views, and it has to stay in
sync with the button’s state.
https://bugzilla.gnome.org/show_bug.cgi?id=682109
In the new designs, we no longer need favRemoveTarget. As it shares a lot
of its functionality with the new showAppsIcon, we refactor and restyle it
accordingly.
https://bugzilla.gnome.org/show_bug.cgi?id=682109
We’ll be repurposing the favRemoveTarget, which calls for it the be
permanently visibe. The favRemoveTarget used to be added to the dash when
needed and removed again when it wasn’t. This made that it always appeared
at the bottom of the dash. Now that we always show it, we also need to
explicitly define it to be at the bottom of the dash.
https://bugzilla.gnome.org/show_bug.cgi?id=682109
We are currently taking "old" placeholders that are still animating
out into account to calculate the new placeholder position - this
causes an annoying bug, where dragging a dash item downwards triggers
quick continous position changes of the placeholder.
Just ignoring old placeholders fixes the issue.
https://bugzilla.gnome.org/show_bug.cgi?id=651842
Running apps are always kept in the dash, so removing them from
favorites just moves them to the end of the favorites list. This
behavior is not immediately obvious, so only show the remove target
when dragging a favorites application that is not currently running.
https://bugzilla.gnome.org/show_bug.cgi?id=644853
We consider spacing and padding in _adjustIconSize, but as we use
the theme node from an actor which is not exposed to the CSS, we
miss the "real" values - correct this.
https://bugzilla.gnome.org/show_bug.cgi?id=662213
DashItem labels have initial delay before showing up, but once the
first label in the dash is visible (meaning the user is very likely
exploring things) and the pointer is moved along the dash, the label
will follow immediately.

Instead of using an St.Tooltip to show the app's name under the icon,
manually position a new St.Label ourselves. Make sure to keep the label
hidden when right-clicking so it doesn't get in the way of the popup menu.
Only one tooltip/label will be displayed at a time.

The last patch in the sequence. Every place that was previously
setting prototype has been ported to Lang.Class, to make code more
concise and allow for better toString().
https://bugzilla.gnome.org/show_bug.cgi?id=664436
All classes that have at least one other derived class (and thus
benefit from the framework) have been now ported. These includes
NMDevice, SearchProvider, AltTab.SwitcherList, and some other
stuff around.

In case _adjustIconSize() is called while the the dash icons are
animating, some extra work is required to yield the expected result.
Skip those extra steps when the icons are not actually animating.
https://bugzilla.gnome.org/show_bug.cgi?id=649248
The current code uses the dash's height and current icon size to
calculate the new icon size. However, the height does not correctly
relate to the icon size while the icons are animating, in which
case the resulting icon size may be wrong.
Rework the function to be independent from the actual icon sizes,
so that a correct size is calculated even when called during an
animation.
https://bugzilla.gnome.org/show_bug.cgi?id=649248
Rather than relying on the caller to hide the remove target and
removed items before calling _adjustIconSize(), move that logic
into _adjustIconSize() itself.

js2-mode is no longer developed and we recommend js-mode these days,

This patch fixes the "apps vanish from alt-TAB bug".
If a "package system" rips away and possibly replaces .desktop files
at some random time, we have historically used inotify to detect this
and reread state (in a racy way, but...). In GNOME 2, this was
generally not too problematic because the menu widget was totally
separate from the list of windows - and the data they operate on was
disjoint as well.
In GNOME 3 we unify these, and this creates architectural problems
because the windows are tied to the app.
What this patch tries to do is, when rereading the application state,
if we have a running application, we keep that app around instead of
making a new instance. This ensures we preserve any state such as the
set of open windows.
This requires moving the running state into ShellAppSystem. Adjust
callers as necessary, and while we're at it drop the unused "contexts"
stuff.
This is just a somewhat quick band-aid; a REAL fix would require us
having low-level control over application installation. As long as
we're on top of random broken tar+wget wrappers, it will be gross.
A slight future improvement to this patch would add an explicit
"merge" between the old and new data. I think probably we always keep
around the ShellApp corresponding to a given ID, but replace its
GMenuTreeEntry.
https://bugzilla.gnome.org/show_bug.cgi?id=657990
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
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
We should only show the trash can when the user starts dragging a
favorite from the dash, not when the user starts dragging an application
that happens to be a favorite via a window or an application icon
in the applications view.
https://bugzilla.gnome.org/show_bug.cgi?id=642895
To deal with different CSS in RTL locales, we used to manually add
an :rtl pseudo class to some actors. With automatically assigned
:ltr/:rtl selectors this is no longer necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=643835
As the dash uses different widths and radii for left and right
borders, we need to use different CSS when it is positioned at
the right of the screen.
https://bugzilla.gnome.org/show_bug.cgi?id=642721
As Main.overview is now usable from the dash's constructor, move
the setup of signal connections there and remove the show/hide
methods which were used as workaround.
https://bugzilla.gnome.org/show_bug.cgi?id=642196
As elements in the dash are scaled to accommodate a growing number
of items, the icon size used may end up rather small. In that case,
dragging items to the dash which are significantly larger than items
in the dash is getting clumsy, so it makes sense for some components
to synchronize the size of drag actors with the currently used icon
size in the dash. To enable other components to do this, make the icon
size a public property.
https://bugzilla.gnome.org/show_bug.cgi?id=639428
We already skip animations for item additions/removals while the
overview is hidden or when initially filling the dash (to avoid
an odd zoom effect when showing), apply the same logic to animations
of icon size changes.
If a window is closed, the list of running applications may change
while the overview is hidden. Animating dash changes is pointless
in this case, so update the dash without animations in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=636156
The dash is created empty and the initial set of items is added
before it's shown for the first time. As the additions of items
is now animated, this results in a slightly odd effect when all
items zoom in at once. So special-case the first time _redisplay()
is called and skip animations in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=636156
In general, all changes in the shell interface should be backed
by animations to give the interface a more natural feel and provide
feedback of what's happening. Currently the dash violates that
principle, as items simply appear/disappear or change size abruptly,
so add animations for application list and icon size changes.
https://bugzilla.gnome.org/show_bug.cgi?id=636156
Clutter containers only take their children's size into account, but
not their scale. As we want the dash to change its size smoothly
when zooming items in/out, we wrap each item in a custom container
which does consider the child's scale.
https://bugzilla.gnome.org/show_bug.cgi?id=636156
When the list of applications in the dash changes, all items are
removed and new ones added. While this approach is nice and simple,
it does not work if we want to animate changes. So rather than
replacing the old list of applications with the new one, figure
out the changes and only apply those.
https://bugzilla.gnome.org/show_bug.cgi?id=636156
Previously the icon size was only adjusted due to changes in the list
of application icons displayed, not when showing or hiding the remove
target. As a result, the remove target could end up cut off, so take
this case into account and adjust the icon size when showing or hiding
the remove target.
https://bugzilla.gnome.org/show_bug.cgi?id=636156
The current approach to adjust the icon size of dash items is rather
expensive: the size of each item is changed from largest to smallest,
until the height of the dash fits the maximum available height, so
quite some ClutterTextures are created and disposed.
A better approach is to calculate the required size beforehand and
only change the icon size when necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=636156
With the current dash layout of a single column, nearly every icon
label ends up ellipsized, even at the largest allowed icon size.
Not showing any labels appears to be the cleanest approach in this
case, so disable them in the dash.
