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.
Add a Notebook class which we then use to pack in separate Hierarchy
and Properties tabs.
Split out the inspector into its own class to avoid bloat in the
main class.
5 seconds is should help ensure we lose work less often on
Alt-f2 restart.
Avoid saving empty lines to history, and filter them out if
we find them.
Minor fixes for the still-not-enabled inspector.
This patch attempts to adjust if we have many tray icons; currently
the simple algorithm is to drop down to a spacing of 8 if we have
more than 6. In the future we should fix the panel layout so that
the clock moves to the side.
Add a dropdown pane triggered by Alt-F2, "lg" which supports interactive
JavaScript evaluation, saving/restoring a history file, as well as
an inspector element to pick by using the mouse.
Using an internal boolean rather than the visibility property seems
more reliable to me. Add a list of internal functions rather than
an if/else chain, so for example an extension could hook something on.
Delete the javascript evaluator in favor of the upcoming lookingGlass.js.
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.
Two calls to _repositionDetails() were done too early,
before the visibility of the results pane had changed,
so they had no effect. Thus when a search was done while
a details pane was active, the pane with the results was
hidden by the details pane.
In addition to fixing this, move the two remaining calls to
the line after changing the results pane's visibility
to make it clearer why the calls are there.
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.
Now clicking on the information icon of the same item a second
time will hide the details pane. Clicking it another time will
show it again, etc.
This is achieved by adding a 'toggle-details' signal which
switches the visibility of the details pane.
Other than the necessary changes, function _selectIndex (in
genericDisplay.js) has been restructured a bit to avoid
duplicating checks.
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.
Rename DocsWidget to RecentDocsWidget (as widgets for most used docs,
docs related to the currently open documents, etc. may be added in the
future), and change the title so that it doesn't abbreviate 'Docs' (for
consistency with the overlay).
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.
Make dash background darker so that the blue color used for indicating
running apps can be visible. Use the dark blue (almost black) color from
Jeremy's mockup.
Make the dash height be the full screen height minus the height of the panel.
Don't use padding on top or on the bottom.
Remove the border from the main dash, but leave it for the results and details
panes. Make the border slightly transparent.
Make sure the details pane is correctly positioned by not applying the
additional padding when determining its x position.
Timeout callback function should not be rescheduled again with the same timeout
because we compute a new timeout and schedule it again instead. So the callback
function needs to return false to not be scheduled again by default.
Make sure that we calculate the next update time correctly.
Store timeout time instead of the timeout delta, so that it doesn't get outdated.
Create a new callback when the time update happens for the original callback.
Make sure last visited time is updated in the details pane by keeping track
of the description actors created for the detail actors.
Add comments to the new functions.
Extend ShellTextureCache by adding the concept of a policy, which
we expose to the public API for loading URIs.
This lets us have the shell tell the cache to keep the information
icon texture around forever.
Secondly, fix the caching of recent info; we shouldn't always be
loading the backup pixbuf. Move recent info loading entirely
into ShellTextureCache.
The semi-transparent gradient on the panel is replaced by a
solid black background. The shadow below the panel is removed.
The clock is put at the center instead of the right side of
the panel and has the date removed. The user icon is hidden.
Instead of boldface, a regular font is used. Padding is added
on each side and between panel elements.
button.js: Allow for custom text colors and fonts.
panel.js: Change the panel colors and layout, remove the shadow.
GenericDisplay wasn't quite completely converted to the ShellOverflowList
model. Since the list now holds all actors, the indexing/wrapping
was incorrect.
Add a property which lets us keep track of how many items are displayed,
use this in genericDisplay.
Avoid setting selectedIndex to -2 when going up with no items.
If we're not displaying any results at all, don't attempt keynav (for now).
Make the ClutterText and ClutterTexture from the status menu
button available to JavaScript, and from there improve the
font definition of the user name.
shell-status-menu.[ch]: Add public get_name() and get_icon()
functions that return the user name label and icon
texture, remove the markup from update_name_text().
panel.js: Set the font for the button consistently with that
of the other panel labels.
Move thumbnail creation into ShellTextureCache. It's now asynchronous,
and we cache the result.
Create a DocManager class which keeps around the DocInfo objects between
invocations. This is also where we ensure we remove thumbnails for
recent items not known anymore.
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.
