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.
ShellDrawingArea is a size-independent wrapper for a ClutterCairoTexture.
Useful when drawing non-fixed size areas.
ShellStack is a simple container class which holds items
in a completely overlapping Z stack. The main difference
from ClutterGroup is that items will be constrained to
(and allocated) the size of the stack, not getting their
preferred size always.
Although methods like gconf_client_get/set_bool() and such are usable
from gjs, get_list/set_list is not, since there's only one method for
all list types. So ShellGConf wraps GConfClient and adds separate
typed list methods.
Also, add a detailed "changed" signal that can easily be connected to
from js, since we can't currently use gconf_client_notify_add()
directly.
The split between this.actor and this.nonOverlayActor in chrome.js is
annoying, but aside from actually subclassing ClutterGroup (which
would have to be done from C), all of the other possibilities are
annoying too.
Add a new icon button in button.js that fades in/out with a short delay when the mouse enters/leaves its parent. Use it for the information button of genericDisplay.
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.
Searching across NoDisplay desktop items can produce weird
results to the user (including duplicates, and items that
aren't really applications at all.) So, don't include them
normally.
But continue including NoDisplay items when we look up the
desktop file for a window, since we want to catch applications
like Evince and Nautilus which are otherwise NoDisplay.

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.

Pack everything we don't want to expand with BigBoxPackFlags.NONE;
this fixes the More... button for the docs section ending up with
a gap underneath it.
Since the More... button for the docs now ends is right at the bottom
of the dash, add some padding to it.

This is not a complete patch; it doesn't attempt to handle the homogenous
property or column major.

Widgets should be horizontally centered in the sidebar. Else they look
out of place (in particular the clock and the applications widgets).
Due to little tricks with the sidebar starting out of the screen to
hide rounded corners, this implies playing with paddings. The patch
decreases the widgets padding from 4 to 2 pixels, removes additionnal
padding on the right, and adds an out-of-screen padding to the widget
box to make up for the negative horizontal position of the sidebar.
The width of a Group actor ends up including the width of its hidden children,
so we were getting a reactive object as wide as the details pane that was
blocking the clicks to the workspaces underneath it even when the details
pane was actually hidden.
Not making the dash Group actor reactive solves this problem. However, we
have to make individual parts of the dash reactive instead so that the clicks
are not passed to the transparent actor underneath them. That transparent
actor is used for dismissing the additional panes when the user clicks over
the workspaces area.
Clutter no longer allows using a clone of an actor that is not a part of
the scene graph. This is what used to happen when we created a clone for
the icon of the item that was being dragged, and then closed the More panes
with the original item, removing the icon from the scene graph. This was
also when happened when the user hit Esc while dragging, which prompted the
overlay to close, removing the original icon from the scene graph.
Rename getIcon() methods to createIcon() to better reflect on the fact that
a new icon is created each time the method is called (we do use cache in
some cases).
Remove a stray log message in overlay.js

The new class AppWell implements the application favorite well
in the Dash component. The previous AppDisplay remains for use
in the More... mode now.
Delete DEFAULT_APPLICATIONS; this is now in GConf.
Rename getMostUsedApps to getTopApps since we now have the
idea of explicit favorites.
Delete some GenericDisplay-related calls from overlay related
to the seletion - we'll reimplement keyboard nav in a more
coherent way later.
Add a GConf key for favorites, and API for retrieving them.
Also add shell_app_system_lookup_basename, which we use from
the app monitor to look up WM_CLASS ids.
Track all windows; at the time of opening (and shell startup)
we call into ShellAppSystem to take the WM_CLASS property and
try to find an associated .desktop file.
Add mozilla-firefox to the list of our WM_CLASS workarounds.
Add shell_global_get_screen, since it's often used.
AppResults and DocResults classes were identical with an exception of
the display class they used and the text label for the results. Merged
them into a single ItemResults class that takes these two additional
arguments.
Move the activate and select functionality inside the callbacks for
'button-release-event' signals of the display item and the information
button correspondingly. This way it is more obvious that this is an
event handling code that needs to return a boolean value for whether
the signal has been fully handled by the actor.
Update the code for checking a display item under the pointer to expect
the item itself rather than its child to be returned by stage_get_actor_at_pos().
This code is now used to display an information button when an item is
drawn under the pointer, so update the comment accordingly.
Add a comment about the use of the transparent background to catch clicks
in the workspaces area when the dash panes are being displayed and dismiss
the dash panes.
Set opacity for the background to 0 instead of using a transparent background
color so that Clutter optimizes the drawing of the background actor.
Fix up the comments about the horizontal gradient code and use 8x1 texture
instead of 8x8.
Make sure the values we assign to the three-stop horizontal gradient
require the use of the three stop gradient, with the middle value not being
right between the side values.
