Now that we use the new 'switch-applications' keybinding for the
application-based alt-tab popup, we can use the 'switch-windows'
keybinding for a more traditional switcher.
Based heavily on the alternate-tab extension from Giovanni Campagna.
https://bugzilla.gnome.org/show_bug.cgi?id=688913
The Shell's alt-tab popup is application-based, so using the
'switch-windows' keybinding for it never really made sense.
Use the newly added 'switch-applications' keybinding instead.
https://bugzilla.gnome.org/show_bug.cgi?id=688913
This hack was part of the custom scroll view code that allowed for
proper scrolling when the actor was near the screen edges. Since
the port to St.ScrollView, it's unnecessary and downright wrong,
causing portions of actors to be clipped. Remove it.
https://bugzilla.gnome.org/show_bug.cgi?id=613194
The appSwitcher has been using a custom scrolling implementation because
St.ScrollView was buggy when it was written. The bugs have been fixed
so remove the custom implementation and move to St.ScrollView.

The old formula worked only when the primary monitor was positioned at the
top of the virtual desktop. When that was not the case, the available
space was miscalculated sometimes resulting in negative numbers, which in
the end produced strangely vertically stretched window thumbnails.
https://bugzilla.gnome.org/show_bug.cgi?id=651130
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.
https://bugzilla.gnome.org/show_bug.cgi?id=664436
Allow push_modal to optionally only work with a keyboard only grab and
use that in altTab as a fallback to allow switching windows while a pointer grab
is in effect (like during DND operations).
https://bugzilla.gnome.org/show_bug.cgi?id=660457
Because we were sorting the Alt+Tab list by user_time rather than
stacking order / MRU, it was possible for the currently-focused window
to sometimes not be the first app in the list. Fix this by using
meta_display_get_tab_list() to get the proper MRU ordering of windows
on the current workspace, and then convert that to an ordered list of
apps.
https://bugzilla.gnome.org/show_bug.cgi?id=645026
js2-mode is no longer developed and we recommend js-mode these days,
so switch the modelines to specify that, and make them consistent
across all files.
https://bugzilla.gnome.org/show_bug.cgi?id=660358
While we allow for arbitrary modifiers in keybindings, both the
alt-tab and ctrl-alt-tab popups close when ALT is not present in
the modifier mask, resulting in ALT being de-facto hardcoded.
Instead, pass the actual modifier mask when invoking the popups.
https://bugzilla.gnome.org/show_bug.cgi?id=645200
Force an allocation at thumbnails creation so we can figure out whether we
need to scroll when selecting.
We also need to show() the whole AltTabPopup before calling _select() so that,
when computing the scrolling offset, the widgets already have their styles
loaded. Otherwise we will miss the switcher list item container's spacing.
https://bugzilla.gnome.org/show_bug.cgi?id=655069
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
Use a longer fade-in time, but with an inout transition, so that the
dialog starts fading in very slowly and then picks up speed after
150ms or so. That way if the user releases Alt+Tab right away, they'll
never actually see the dialog.
https://bugzilla.gnome.org/show_bug.cgi?id=652346
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.
https://bugzilla.gnome.org/show_bug.cgi?id=636963
AltTabPopup was calling global.stage.get_actor_at_pos() "to force a
stage relayout", but that function does not actually have that effect.
It was also occasionally causing Clutter warnings (possibly due to a
clutter pick-buffer-caching bug?). So just remove the call.
https://bugzilla.gnome.org/show_bug.cgi?id=650317
The initial selection of the Alt+Tab dialog was happening before the
dialog was shown and allocated, and so the "do we need to scroll"
check used bogus coordinates. Fix by showing the dialog (and forcing
an allocation) first.
https://bugzilla.gnome.org/show_bug.cgi?id=647807
Alt+Tab's special case of "switch to the most-recently-used window even if
it's in the same app" is actually an hindrance for users to get a firm mental
model of Alt+Tab. Now that we have Alt+Above_Tab the special case is no longer
needed.
https://bugzilla.gnome.org/show_bug.cgi?id=647907
For applications with no proper desktop file, the window icon is
used as application icon in the tab switcher, but it won't have
the correct icon size. The current approach is to add additional
padding to these icons - the size turns out inconsistent with
other icons, but the icon appears sharp. For the dash it has been
decided that unsharp icons are less evil than differing icon sizes,
so icons are scaled up to the "right" size - for consistency, do the
same in the alt-tab switcher.
https://bugzilla.gnome.org/show_bug.cgi?id=643300
For historical reasons, we had both StClickable and StButton, which
were nearly identical. StButton was more widely-used, so keep that and
port all StClickable users to that.
https://bugzilla.gnome.org/show_bug.cgi?id=640583
When aiming for the thumbnails with the mouse one might cross an
icon by accident which causes the thumbnail list to be closed, which is
frustrating.
Fix this by delaying the icon activation when the thumbnail list is
open.
https://bugzilla.gnome.org/show_bug.cgi?id=636650
If the switcher is destroyed without ever being fully shown (either
because it couldn't get a keyboard grab, or just because there are no
apps to display), destroy it immediately rather than tweening it
towards destruction, since its contents haven't been built yet and
_allocate() will throw errors if it runs.
This makes it consistent with other parts of the UI and will let the
a11y code use the rule "has_style_pseudo_class('selected') =>
ATK_STATE_SELECTED"
https://bugzilla.gnome.org/show_bug.cgi?id=637830
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.
https://bugzilla.gnome.org/show_bug.cgi?id=618885
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
The keyReleaseEvent handler does not take into account that a
user might release Alt while still holding shift
(the keycode becomes Meta_L/R in that case).
The result is that the switcher stays open which is unexpected.
https://bugzilla.gnome.org/show_bug.cgi?id=629368
In Clutter 1.2, clutter_event_get_keysym() ignored the state of the
Shift key. In 1.4, it does not, so we have to adjust our comparisons
accordingly.
https://bugzilla.gnome.org/show_bug.cgi?id=627782
The design calls for item to not appear abruptly, but not too slow
either - 100ms seems to be a good sweet spot for elements which are
supposed to appear "instantly".
Add a fade effect to the alt-tab popup and set the timings for other
fade effects to 100ms.
https://bugzilla.gnome.org/show_bug.cgi?id=621247
SwitcherList.actor is no longer a St.BoxLayout but a
GenericContainer now, so the hack in AppSwitcher._getPreferredHeight is no
longer needed (it is called with the correct width now).
https://bugzilla.gnome.org/show_bug.cgi?id=613194
Per design discussion, change things back so that when choosing
an individual window, we raise only that window. However
when we select an application, raise all windows.
A behavioral change required to clearly differentiate these
is that when the window thumbnail list is popped up, it no
longer has the first window selected by default. Therefore
the user has to explicitly press the down arrow or use the
mouse to enter individual window selection mode.
https://bugzilla.gnome.org/show_bug.cgi?id=617959
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.
In preparation for adding magnification, "uiGroup.patch", organizes the stage
along the following lines:
Stage
*Magnifier
UI group
Window group
Chrome group
Overlay group
Alt tab
App display
Chrome
...
This allows a magnifier actor to clone and magnify the UI group. The magnifier
is a sibling of the UI Group in this stage oraganization -- see the next patch,
"Magnifier.patch".
We can't use gdk_display_get_pointer/gdk_window_get_pointer from gjs
when XKB is active. We already had a wrapper that did the
get-modifier-state part of that, but some places also need the
get-pointer-location part of it. So update our wrapper to return both,
and update js code to use it.
https://bugzilla.gnome.org/show_bug.cgi?id=613428
The POPUP_LIST_SPACING constant was used for the AltTabPopup.actor's padding,
AltTabPopup.actor's spacing and SwitcherList._list's spacing.
Switch to CSS and remove the constant.
https://bugzilla.gnome.org/show_bug.cgi?id=613195
Limit the AppSwitcher to the screen size by either downscaling or
scrolling.
We scale the icons down up from 96, 64, 48, 32 to 22 and start scrolling
if we still fail to fit on screen.
The thumbnail box is shifted to either left or right, when failing to
fit we scroll here to.
To prevent from being offscreen at the buttom we adjust the thumbnail
height to fit.
The old positioning logic is replaced with a ShellGenericContainer to
implement a custom allocation system.
https://bugzilla.gnome.org/show_bug.cgi?id=597983
Having StDrawingArea use ClutterCairoTexture causes circularity
problems with sizing - StDrawingArea wants to use its allocation for
the size of the texture, but ClutterTexture wants to use the size of
the texture to determine the requited size.
Avoid this by making StDrawingArea directly use Cairo and CoglTexture;
while doing this, the API is changed a bit for simplicity and to
match our use case:
- Instead of clutter_cairo_texture_create(), we have
st_drawing_area_get_context() to retrieve an already created
context. This can only be called in the ::repaint signal.
- The ::redraw signal is changed to ::repaint so we can have
st_drawing_area_queue_repaint() that doesn't collide with
clutter_actor_queue_redraw()
- ::repaint is now emitted lazily when painting the actor rather
than synchronously at various different points.
https://bugzilla.gnome.org/show_bug.cgi?id=611750
Fallback icons (i.e icons < requested size) cause the box in the switcher
to be a smaller rectangular item instead of the normal sized square one.
Fix that by putting the icons in a St.Bin with the correct size.
https://bugzilla.gnome.org/show_bug.cgi?id=609777
This bug happened because the thumbnail box was only maxed, not set to 256x256.
Standard window thumbnails would max out only the width to 256. Having a window with
its height greater than its width meant that the height would max out, but not the
width, causing thumbnails to look uneven.
https://bugzilla.gnome.org/show_bug.cgi?id=604963
The altTab.js and app well code weren't sharing really
any functionality anymore; un-merge the appIcon code back
into appWell, and have a simple icon + text display for
altTab.
Port AppWell to St and CSS.
https://bugzilla.gnome.org/show_bug.cgi?id=602131
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
It's nicer to have ShellDrawingArea as a St widget so it can
participate more cleanly in CSS styling, such as queuing a redraw
automatically on style changes, and allowing subclasses to use
CSS styling.
https://bugzilla.gnome.org/show_bug.cgi?id=602131
This make it is easier for the user to figure out on which workspace the
windows are. For instance, terminals related to various activities and put on
different workspaces were previously displayed as an uniform list, with no
visible distinction between the ones from the current workspace and the others.
Now they are physically separated by a thin gray line.
This is also consistent with the way applications are displayed in the
AppSwitcher.
https://bugzilla.gnome.org/show_bug.cgi?id=597944
The two parts were mapping windows to applications, and
recording application usage statistics. The latter part
(now called ShellAppUsage) is much more naturally built on top of
the former (now called ShellWindowTracker).
ShellWindowTracker retains the startup-notification handling.
ShellWindowTracker also gains a focus-app property, which is
what most things in the shell UI are interested in (instead of
window focus).
ShellAppSystem moves to exporting ShellApp from more of its
public API, rather than ShellAppInfo. ShellAppSystem also
ensures that ShellApp instances are unique by holding
a hash on the ids.
ShellApp's private API is split off into a shell-app-private.h,
so shell-app.h can be included in shell-app-system.h.
Favorites handling is removed from ShellAppSystem, now inside
appFavorites.js.
Port all of the JavaScript for these changes.
https://bugzilla.gnome.org/show_bug.cgi?id=598646
Previously, we had ShellAppInfo, which contains fundamental
information about an application, and methods on ShellAppMonitor
to retrieve "live" information like the window list.
AppIcon ended up being used as the "App" class which was painful
for various reasons; among them that we need to handle window
list changes, and some consumers weren't ready for that.
Clean things up a bit by introducing a new ShellApp class in C,
which currently wraps a ShellAppInfo.
AppIcon then is more like the display actor for a ShellApp. Notably,
the ".windows" property moves out of it. The altTab code which
won't handle dynamic changes instead is changed to maintain a
cached version.
ShellAppMonitor gains some more methods related to ShellApp now.
In the future, we might consider changing ShellApp to be a GInterface,
which could be implemented by ShellDesktopFileApp, ShellWindowApp.
Then we could axe ShellAppInfo from the "public" API and it would
return to being an internal loss mitigation layer for GMenu.
https://bugzilla.gnome.org/show_bug.cgi?id=598227
The down arrow is shown when an application with more than one
window is selected, but the window list is not always displayed.
This patch fixes the fact that the arrow was not hidden when one
focus an app with a single window when coming from an app with
multiple windows, if the window list was not displayed.
https://bugzilla.gnome.org/show_bug.cgi?id=597791
When we get a ClutterModifierType from Clutter, it might contain
bits not in the enumeration. See bug 59771 for a similar problem
with GdkModifierType.
Add a wrapper Shell.get_event_state() around clutter_event_get_state()
to mask these bits out and only return approved bits.
https://bugzilla.gnome.org/show_bug.cgi?id=597735
gdk_display_get_pointer() sometimes returns values for the mask that
aren't part of the GdkModifierType enumeration, which gjs doesn't like
(bug 597292). Work around that by adding a C wrapper that strips out
the extra flags.
https://bugzilla.gnome.org/show_bug.cgi?id=597559
Add a "size" parameter to allow changing the AppIcon size, and then
simplify the constructor by taking an object with parameters like
gobject-introspection constructors do, rather than taking a large
number of miscellaneous arguments.
https://bugzilla.gnome.org/show_bug.cgi?id=597498
This slightly changes the behaviour of the alt+tab window, this way:
when using alt-tab on a workspace that contains two or more windows from
the same window, the application selected when hitting alt+tab is the
currently selected application, but the highlighted window is the next
one.
Intended goal is to make it easier to cycle around windows of the same
application while not having to cycle through all the applications first.
https://bugzilla.gnome.org/show_bug.cgi?id=590563
This makes a visible distinction between the apps that only have minimized
windows on the current workspace and the ones that have no window on the
workspace.
https://bugzilla.gnome.org/show_bug.cgi?id=590563
This allows defining some custom policy for size allocation.
Currently, the minimum width is always used, but it can be tweaked
afterwards when a sizing policy has been defined.
https://bugzilla.gnome.org/show_bug.cgi?id=590563
Following the idea expressed in bug 590563 by mccann ("Minimized or
hidden applications should appear at the end of the list"), we should
also put applications that have no visible window in the active
workspace at the end of the alt-tab window list, after apps which have
minimized windows in the active workspace.
Fix panel, app switcher, and looking glass to limit themselves to the
primary monitor, and run dialog to limit itself to the monitor
containing the currently-focused window.
The overview is also limited to the primary monitor now (with the
other monitors being blacked out), although the workspaces within the
overview are shaped like the full "screen" (the bounding box of all
monitors). To be fixed later.
https://bugzilla.gnome.org/show_bug.cgi?id=593060
Unlike icons in the application well, do not show the glow used to
indicate running apps. It is somewhat redundant here. These are all
running apps and it is fairly clear from the window list if there are
multiple instances available, according to mccann.
https://bugzilla.gnome.org/show_bug.cgi?id=590563
The default AppIcon gray border color isn't very visible against a
dark gray background, but a white border looks too bold in the Well. So
allow the caller to override the AppIcon border color, so that the Well
can use gray-on-black and the AppSwitcher can use white-on-gray. (And
then revert the AppSwitcher back to the translucent gray background.)
https://bugzilla.gnome.org/show_bug.cgi?id=596337
The "lightbox" effect had support for highlighting a particular
rectangular region on the taskbar when Alt-Tabbing to a minimized
window. Since we no longer use the taskbar, this code is just cruft
now.
Part of https://bugzilla.gnome.org/show_bug.cgi?id=590563
We now have functionality in Mutter to grab the keyboard on behalf
of a plugin. This avoids interactions with the key handling code
in Mutter that could leave the user with an inconsistent state
and no way to get out of it.
src/shell-global.[ch]: Change shell_global_grab_keyboard() and
shell_global_grab_keyboard() to shell_global_begin_modal()
shell_global_end_modal() and call mutter_plugin_begin_modal()
mutter_plugin_end_modal() rather than directly grabbing the
keyboard.
main.js: Call global.begin_modal/end_modal from Main.startModal()
and Main.endModal()
altTab.js; Remove call to Main.startModal() - we're letting Mutter
handle modality for Alt-Tab.
main.js lookingGlass.js overview.js runDialog.js: Rename
Main.startModal() to Main.beginModal() for consistency with
naming in mutter and ShellGlobal.

Change the "overlay" actor to be a group of 4 actors that we can
rearrange so as to have a hole in the middle (to cover up the whole
screen except for the highlighted icon). For non-iconified windows, we
still highlight them the old way (raising them above the overlay),
because we don't want square highlights around shaped windows.
Make the indicator in the pop-up move faster.
Quickly fade in the "overlay" window when starting, rather than
showing it abruptly. Destroy it right away rather than just hiding it
when the AltTabHandler is destroyed.
Fix the font size to be the same as the "Activities" button.
Fix a warning when tabbing past an iconified window.
This is a fairly simple implementation, not all that different from
plain metacity's. Further improvements could be made to
js/ui/altTab.js in the future.
