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.

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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=636156
When checking the type of a DND source, instead of checking
'instanceof Workspaces.WindowClone' accept any actor with realWindow
and metaWindow properties. This will be useful to support a separate
type of actor dragged from workspace thumbnails.
https://bugzilla.gnome.org/show_bug.cgi?id=640996
1. Both functions leaked the nodes in priv->children
2. st_container_remove_all wasn't properly updating first_child and last_child
3. remove_all() is almost never right since it won't cause signal handlers
on the children to be removed. In the rare cases where it might be needed
the caller can simply use clutter_container_remove().
https://bugzilla.gnome.org/show_bug.cgi?id=640781
AppWellIcon is used both in the dash and view selector. As the dash
requires manual sizing, it is not possible to set the icon size used
in the view selector in the CSS, but icons will use the default size
(unless set manually as in the dash).
Expose the params parameter of BaseIcon and enable manual resizing
only for AppWellIcons in the dash.
https://bugzilla.gnome.org/show_bug.cgi?id=639428
Show a positional indicator where a new favorite will be added and
make the favorites re-orderable. Also allow the removal of favorites
using drag-and-drop according to the mockups.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
The view selector is a tabbed interface with a search entry. Starting
a search switches focus to the results' tab, ending a search moves the
focus back to the previously selected tab. Activating a normal tab
while a search is active cancels the search.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
With the new layout, search results will be displayed in an independent
view like window previews, applications and possible future additions;
it does not make much sense keeping it with the switching logic, so move
the code to its own file.
Also remove the dash-prefix from the relevant style classes.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
The new dash implementation is a single-column vertical sidebar,
whose items are scaled dynamically to fit the available height.
If the height is still exceeded after scaling down to a minimum
item size, excess items are cut off.
The now unused old dash implementation is renamed to OldDash, as
its code will be used as a base for the new view selector element.
https://bugzilla.gnome.org/show_bug.cgi?id=634948
We should not be showing the cursor in the search entry in the overview
if the user's input will be appearing elsewhere, such as in the run dialog,
in the Looking Glass console, or in the notification's response field.
Add _st_actor_contains() in st-private for use within St, and
monkey-patch in a Clutter.Actor.contains() for use by javascript, and
then replace all the duplicate implementations with one or the other
of those.
https://bugzilla.gnome.org/show_bug.cgi?id=621197
As the design calls for smooth transitions whenever possible, use
a similar fade effect for the all-apps and more-docs menus as for
the panel menus.
https://bugzilla.gnome.org/show_bug.cgi?id=620775
As the search entry captures the pointer when activated, the hover
state is not updated properly when the activation is cancelled
(either by clicking outside the entry or by hitting Escape).
Update the state manually in these cases.
https://bugzilla.gnome.org/show_bug.cgi?id=611095
When dragging windows in linear view, the workspace zooms out to
allow moving the window to other workspaces. Enable the same
behaviour for items dragged from the dash.
https://bugzilla.gnome.org/show_bug.cgi?id=618055
This is our convention.
The only exceptions are double quotes for words in comments that give
them a special meaning (though beware that these quotes are not truly
necessary most of the time) and double quotes that need to be a part
of the output string.
Also, remove a lot of cruft from genericDisplay.js leftover from
previous St-ifications, and remove the pre-gtk-2.16 hacks from the
status tray in panel.js (which are much less needed with the
nearly-all-black panel anyway).
https://bugzilla.gnome.org/show_bug.cgi?id=614516
Since style_class and pseudo_class are space-separated lists of names,
add new methods to add and remove individual names rather than just
re-setting the entire name.
Update existing code to use the new pseudo-class methods where
appropriate. In some cases, this may result in actors having multiple
pseudoclasses where previously they only had one at a time, but there
don't seem to be any visible differences.
(There are some places that could usefully use the new style_class
methods as well, but this patch doesn't change them.)
Also, update test-theme.c to test the new methods.
https://bugzilla.gnome.org/show_bug.cgi?id=604943
Instead of setting a fixed size in the CSS which only works well
with a limited range of screen resolutions, assign a relative
size in the code.
While this takes away some flexibility from theme authors, it is in
line with most elements in the overview (workspaces area, dash).
Also expose the menu panes vertical alignment, so that more-apps aligns
to the workspaces area's top and more-docs to the bottom.
https://bugzilla.gnome.org/show_bug.cgi?id=610872
Brute force merge these two by essentially replacing St.TextureCache
with a (renamed) Shell.TextureCache.
One function was added for convenience, namely "st_texture_cache_load_file_simple".
St.TextureCache had a function to load a texture from a filename, and it
returned NULL on error but only half the callers actually checked this. This
function is better.
https://bugzilla.gnome.org/show_bug.cgi?id=607500
The previous commit broke activation when selecting an actor
from a custom renderer. Fix this by explicitly defining a method
activateSelected on the search renderer.
Switch to using an application icon as per design.
We need to drop the 4 pixels padding to ensure we fit 3 icons.
There was a typo where getVisibleCount should have been getVisibleResultsCount.
https://bugzilla.gnome.org/show_bug.cgi?id=610740
Currently, activating a search result always opens a new window. Change
this behavior, so that if an application has open windows, the most
recently used one is activated instead.
Also change the implementation of dnd of search results to allow providers
to treat results activated via dnd differently.
https://bugzilla.gnome.org/show_bug.cgi?id=610027
The high level goal is to separate the concern of searching for
things with display of those things; for example in newer mockups,
applications are displayed exactly the same as they look in the
AppWell.
Another goal was optimizing for speed; for example,
application search was pushed mostly down into C, and we avoid
lowercasing and normalizing every item over and over.
https://bugzilla.gnome.org/show_bug.cgi?id=603523
StClickable replaces ShellButtonBox. Reduce the number of
button-like things by deleting button.js.
To do so, add CSS style for the actitivies button.
https://bugzilla.gnome.org/show_bug.cgi?id=602131
Mostly a straightforward porting of style code to CSS, except
that various bits of other code referenced a few GenericDisplay
constants, so those needed to be ported as well.
Add some padding at the top between the close button and the items.
Center the text and description.
https://bugzilla.gnome.org/show_bug.cgi?id=600734
Places is one of the dash sections and it should be included in search results.
Factor out the code for getting and updating the information about places from
Places to PlacesManager.
Introduce PlaceInfo class that contains information about the place and can be
used by classes that display it in different ways. Rename classes so that their
names are consistent with corresponding classes in appDisplay.js and
docDisplay.js
https://bugzilla.gnome.org/show_bug.cgi?id=599125
If we had a pending search processing, finish it when the user
activates the entry.
This is a small conceptual change; the large diff is simply
moving the search implementation (unedited otherwise) from
an anonymous inline to a named function so it can be called
sanely in _activate.
https://bugzilla.gnome.org/show_bug.cgi?id=598111
We shouldn't show all sections each time the search is updated because that
breaks viewing search results for a single section and flickers headers for
sections with no results.
The text "Browse" used for the buttons on the dash section headers is a
little obscure and tends to translate into something that doesn't fit
well.
Going back to "More" will hopefully be more manageable in translation.
https://bugzilla.gnome.org/show_bug.cgi?id=596433
We queue a 150ms timeout when the user starts typing to avoid searching
for the first keystroke. However, this caused us to change to the search
mode, but show the leftover state of the search displays from an
earlier search state.
Instead, just hide the results sections until we've actually performed
the current search once.
https://bugzilla.gnome.org/show_bug.cgi?id=596119
controls if there is only one page of results
This makes the search results display more streamlined.
Make sure that we move the selection to a different section if we are going
from displaying a single section to displaying all and the section that
used to be displayed alone doesn't have any results.
We will be adding more search results sections, so we should store the intended
order of the search results sections and their properties in an array of data
structures.
This information allows us to have generic code for creating the search results
sections, moving the selection between them and transitioning between showing
all sections and a single section.
Before Clutter gained accessors for event information, we had
shell_global_ functions. Now that Clutter has them, use them and
delete the ShellGlobal code.
http://bugzilla.gnome.org/show_bug.cgi?id=594561
There is no need to show two headers when we are only displaying a single
section of search results, so we merge the section header with the main
header in that case.
Show a back button on the left of the main header to get back to the results
for all sections.
Remove this._showTooltip flag from SearchSectionHeader because we no longer
show this type of header when we want to suppress the tooltip.
Add this._appSearchResultsOnlyShown and this._docSearchResultsOnlyShown
flags to track when a single section is shown more cleanly.
Select an item by default when the search results are displayed.
Enable moving from one section of search results to another with key navigation.
Reset the selection when the search is updated or a new page is displayed
or the transition between viewing multiple sections and viewing just one is made.
Make Button class purely about adding visuals, and use ShellButtonBox
for behavior. API equivalences:
shell.button => shell.actor [for consistency]
staysPressed parameter to constructor => replaced by manually setting
the 'active' property of button.actor as appropriate
pressIn/release => button.actor.active = true/false
enter-event/leave-event signals => button.actor notify::hover
Along the way, this fixes a bug with the user status menu where it was
not getting set to active because the button was getting a leave
(triggered by the menu popping up and grabbing the pointer) before for
button release, which disabled the staysPressed behavior.

Use bigger font and brighter color for the search results section headers.
Add more padding.
Display "(see all)" tooltip in the section headers on mouse-over.
(Still TODO: supressing that tooltip when all results are already being shown.)
All our font sizes were in px, other than the size for the text in
the search entry. Switch that from 12 to 16px (which is the same size
at the standard 96dpi), it doesn't become out of scale if the DPI
is different. (Using fixed px sizes isn't probably what we want to
do in the long term; moving to style sheets will be a good place to
fix that. But better to be consistent.)
http://bugzilla.gnome.org/show_bug.cgi?id=593212
Display only first page of search results by default for each section and
allow clicking on the section header to view all the results for a given
section. This design will allow us to easily move from paging to scrolling
without having to stack multiple scrollbars in a single pane.
Display a total results count next to the section name. This serves as an
indicator that there are more results. The section header pre-lights to
indicate that it can be clicked on.
Make sure we go back to the first page of results when we exit a single
section mode. Make sure we re-instate all result sections if the search
mode is left.
Close the only section search mode on Esc, and only close the search
when Esc is hit again.
Display search results in the dash instead of showing them in a separate pane.
We get dynamic allocation for the section height based on the number of
results, but a lot of the problems with the previous search results display,
such as displaying empty sections and paging overflow are still present.
Also, we don't yet close the browse pane for applications or documents when
we display the search results and only replace it if we are showing the
details pane, so all that looks weird. We'll need to work out the interaction
for these cases.
The design has smaller icons in two columns. Add a new
custom display to docDisplay for it.
Clean up some of the texture cache handling for recent URIs so
it's not size-dependent, since the dash size is now different
from the default GenericDisplay size.
We need to use the -lib variant which in turn uses the
GETTEXT_PACKAGE define, because the default translation
domain is actually mutter, not gnome-shell.
We don't have a lot of strings, and what ones we do have we've
been avoiding duplication. This patch adds calls to _() i.e. gettext
for those strings we do have.
There was some weirdness relating to when the search pane is shown
in a timeout, and how that relates to setSearch. Instead of doing
this in the timeout, just call setSearch() in the timeout. The
pane hide/show state is directly controlled from the handler.
Remove the last use of passing width into Dash by having the
Pane with the previews scaling dynamically and relying on
Clutter scaling.
If we only have one workspace, don't display a selection frame
for it.
Rework Dash into a searchArea and sectionArea, which get
explicitly sized by overlay.js. We use the workspaces size
to choose the size of those dash areas.
Switch dash colors/boxes etc. to ones from shell-black02.
Add a gradient to the panel.
Add a magnifier.svg for use in search.
Replace 'overlay' with the more descriptive name 'overview'
where the Activities Overview is meant. Call it Overview
(capitalized) in code comments.
The overlay-group and overlay-key provided by Mutter are not
affected, since they may be used for other components than
the Activities Overview.
The "expanded background" that is behind the workspaces etc. in the overview
should be removed. It isn't in the designs, it is distracting, and it breaks
the overview metaphor.
At least temporarily, just make the background of the overview black.
Change the pane popup to black as well, but keep a blue border so that
it is visually distinguished from the background.
Based on a patch by Colin Walters, with fixes from Marina Zhurakhinskaya.
Use ShellGenericContainer to implement a fully dynamic layout
for the application well. It's still fixed to 4 columns by default,
but no longer requires a fixed width to be passed in on start.
With another chunk of work, it could likely try to adjust to
the case where we can only fit fewer than 4 items in the well.
Remove the border highlighting on mouseover, since that caused
reallocations, and the grid layout isn't trivial.
Delete the unused shell_global_get_word_with function.
This patch is a near-total rewrite of the Dash. First, the dash
code moves into a separate file, dash.js.
Inside dash.js, the components are more broken up into separate
classes; in particular there's now a Pane class and a MoreLink
class. Instead of each section of the dash, when activated,
attempting to close all N-1 other sections, instead there
is the concept of a single "active pane", and when e.g. activating
the More link for documents, if we know there's an active pane
which happens to be the apps, close it.
Many redundant containers were removed from the dash, and all
manual width, height and x/y offsets are entirely gone. We move
the visual apperance closer to the design by using the view-more.svg,
etc.
To complete the removal of height/width calculations from the dash,
we also had to do the same for GenericDisplay. Also clean up
the positioning inside overlay.js so calculation of children's
positioning is inside a single function that flows from screen.width
and screen.height, so in the future we can stop passing the width
into the Dash constructor and call this once and work on screen
resizing.
