When the user click+hold+release over the icon, the effect we want
is for the menu to stick around.
Also, allow the user to mouse over the actual windows and select
them directly. If the user mouses over a window, reflect that in
the menu.
Rather than starting lightboxing only when the mouse enters the
menu, start it when an application filter is set.
Also delete a stale function in WindowClone from previous work.

When we have multiple windows for an application, implement the following
behavior:
* On click + immediate release, go to the most recently used
* On click, hold for 0.6s, pop up a menu with windows, filtering
the window list to just those windows.
Mouse over on the window list highlights the moused-over window.
Implement this by splitting well item into InactiveWellItem
and RunningWellItem, sharing a base class BaseWellItem.
Rather than just launching if we weren't already running, always
relaunch, which happens to make Firefox, etc. work. See
the comment in the commit for more explanation.
We had multiple copies of the code to position a drag actor given a particular
source. Instead, just put it inside dnd.js.
Second, rather than test for GenericDisplay/WellDisplayItem etc.,
in various places, add a new method on each source "shellWorkspaceLaunch"
which both marks the item as being droppable on a workspace, and is
called by the workspaces code to launch the item.
Use MetaGroup for a window when looking up applications. If
we know the application for a TYPE_NORMAL window in the group,
use that.
However, we aren't always going to know the application for a window. In
that case, create a fake one.
ShellAppInfo has a "transient" flag so we know not to write these
fake apps to the usage file.
Clean up the idle focus handler to better handle the case where
no window is focused, and where we don't want to track the
particular window.
Update track_window to create the fake window.
When a window goes away, we want to delete the usage.
Rewrite shell_app_monitor_get_running_apps to be based
on the window_to_app hash, because that's what has the pointer
to ShellAppInfo*. Before we were looking up all ids through
ShellAppSystem, but that shouldn't be holding a ref to transients.
Change the well display icon to be centered, since our icons for
window apps aren't 48 pixels.
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.
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.
Previously, ShellAppSystem only loaded (and cached) the set of
.desktop files from applications.menu and settings.menu, using
the gnome-menus library. The ShellAppInfo structure was
a "hidden typedef" for GMenuTreeEntry.
But we need to support loading an arbitrary .desktop file. Thus,
refactor the ShellAppInfo into a real struct, with a refcount,
and allow it to point to either a GMenuTreeEntry or a GKeyFile.
Also, in the case where we fail to lookup an icon for an
application, ensure we return a 0 opacity texture.
When WellGrid had no child it was doing a division by zero,
which screwed up the calculation for the height request and
having it ask for a negative number. This commit fixes this
by always requesting 0 in this case.
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.
It's easier to explicitly call Main.overlay.hide() instead
of chaining activation signals, this got lost in a mix between
the big dash rewrite and ongoing changes to the Application well.
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.
The previous application monitoring code was originally designed
to be based on WM_CLASS, which was then resolved on a server.
We have that resolution code locally now, so instead
of saving WM_CLASS data, save application IDs.
Also, inside the WM we have a much better
infrastructure for tracking windows. In particular, rather
than polling, we can just watch for focus notification on
the display, and window add/remove.
Instead of polling XScreensaver, use DBus to watch org.gnome.Session
which already has an idle time watch.
Now there is no polling at all inside the monitor.
We had duplicate code in appDisplay and workspaces for handling activating
a window; unify that inside workspaces, add an API to Main.overlay to
access it from both contexts.
Also, explicitly raise the clone we're activating to the top
before starting the animation to leave the overlay.
Don't use a clone of an actor that's not part of the scene graph for the
item previews. This patch fixes previews in the details pane for documents
for which we don't have full previews and for applications.
Use create_icon_texture() from AppInfo instead of looking up the file
for gicon when creating an application icon for the details pane.
The experiment with avoiding ellipsization was a definite failure;
several translations have very long names, and we'd end up
with a single column.
Also fix extra padding; we only want some space at the top, not
left/right.
Corresponding with the design, if an application is in a running
state (has > 0 windows open), draw a glow behind the name.
To make the display look a bit nicer, set the width of each item
to be equal to the longest word among all the items.
Before, we looked up application data in several ways; the ShellAppSystem
exported just application ids (though it parsed the .desktop files internally),
and we'd create a Gio.DesktopAppInfo object (reparsing the desktop file again),
wrapping that inside a JavaScript AppInfo class, and finally the AppDisplay
would again parse the .desktop file to get the categories.
Also, to look up applications by id previously, we traversed the entire
menu structure each time.
Some qualities such as the NoDisplay flag were not easily exposed in the old
system. And if we wanted to expose them we'd have to change several different
application information wrapper classes.
All in all, it was quite suboptimal.
The theme of this new code is basically "just use libgnome-menus". We do
not call into Gio for app lookups anymore. The new Shell.AppInfo class
is a disguised pointer for the GMenuTreeEntry item.
To fix the caching, we keep a simple hash table of desktop id -> ShellAppInfo.
Rework the previously extant Application category code to display
in the expanded list. Add a "Frequent" category which corresponds
to the most_used_apps, and selected by default.
Instead of adding the background and shadow as expanded items to
the results/details panes as fixed, we slave the background/shadow
sizes to the results using notify::allocation.
Also clean up the code for sizing the details pane, using a common
function which adjusts its x position in one place.
This converts GenericDisplay to totally dynamic layout, where
we display as many items as we can, and the rest cleanly overflow
into pages.
For now, remove multi-column; to readd this, we can pack multiple
display items into a single ShellOverflowList item.
It looks funny to have the "more running apps area" there as a gap
when empty and dragging to it is an unintuitive way to remove stuff
from the favorites list, in any case, so just hide the area when
empty.
