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
Currently there is a serious problem with ellipsization in various
parts of the overview. While wrapping the label or giving it more
space may be appropriate approaches for the application view, neither
works very well for the dash - possibly the best option there is to
not show the label at all.
So add a constructor parameter to BaseIcon to allow hiding the
label.

With workspaces now being stacked vertically, the horizontal
indicators in the workspace switcher are rather odd. There are
some designs for an improved workspace switch animation, but
it may take a while to implement them, so for now just change
the orientation of the existing switcher.
https://bugzilla.gnome.org/show_bug.cgi?id=641931
Point the arrow to the center of the sourceActor's content box, rather
than its allocation, in case it has asymmetric padding (as the
rightmost message tray summary item does).
https://bugzilla.gnome.org/show_bug.cgi?id=641728
Commit c86a977564 removed :pressed from the list of styles which
highlight panel buttons, so the button highlight is now lost when
mousing over menu items. This is not the behavior we want, the
buttons should keep their highlight while being "active". Rather
than adding back the pseudo class to the CSS, let buttons use the
:active pseudo class when the menu is open, which makes more sense
than :pressed anyway.
The status icon should always be visible if more than two layouts
are configured. The settings key which was used to enforce hiding
the icon in this case as well has already been removed from the
g-s-d schema, causing an error on startup.
Intead of using a St.Group and tweening the position of the controls
actor, use a St.GenericLayout and tween a Javascript property. This
allows us to more reliably track the height of the overall workspace
display and propagate it to the controls actor.
https://bugzilla.gnome.org/show_bug.cgi?id=640996
With workspace thumbnails, we don't switch workspaces when dragging windows
between workspaces or adding new workspaces, so we also shouldn't switch
on launch.
* Add workspace parameters to shell_doc_system_open(),
shell_app_activate, shell_app_open_new_window()
* Pass a 'params' object when activating items in the overview with
two currently defined parameters: workspace and timestamp. (timestamp
is only implemented where it is easy and doesn't require interface
changes - using the global current timestamp for the shell is almost
always right or at least good enough.)
https://bugzilla.gnome.org/show_bug.cgi?id=640996
At the end of a drag operation, we would invoke the code to slide the
controls in (because we were no longer DND'ing and not hovering) and
then immediately afterwards invoke the code to slide it back out when
we got the ENTER event from the end of DND. While the immediately
overridden tween probably won't have any visible effect it's better
to avoid this, so wait to update the zoom state until BEFORE_REDRAW.
https://bugzilla.gnome.org/show_bug.cgi?id=640996
With automatic workspace management, explicit controls to add and
remove workspaces are no longer necessary. We also can remove the
use of addWorkspace for middle-button-click on a launcher since
launching on the last empty workspace will do the right thing.
https://bugzilla.gnome.org/show_bug.cgi?id=640996
With workspace thumbnails, we want to make workspace switching
something that happens largely under the users control, so don't
switch to newly added workspaces in the overview.
https://bugzilla.gnome.org/show_bug.cgi?id=640996
Add workspace thumbnails to the workspace controls area. The user can
click on the thumbnail to switch workspaces and can also drag windows
out of the thumbnail to other workspaces.
https://bugzilla.gnome.org/show_bug.cgi?id=640996
Moving the base tracking of restacking to WorkspacesDisplay will allow
us to use it to update stacking in the workspace thumbnails as well as
in the main workspaces.
https://bugzilla.gnome.org/show_bug.cgi?id=640996
Instead of having a separation between popping the controls out on hover
and zooming out for DND, always do both at once. This is necessary because
when we added workspace thumbnails the controls will get bigger, so we need
to make sure we zoom out far enough so that the windows don't overlap the
controls.
https://bugzilla.gnome.org/show_bug.cgi?id=640996
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
The new plans for a row of workspace thumbnails on the right side of the
overview means that the mental model we present to the user will be
vertical, so switch the Metacity workspace layout to be vertical and
adjust the keybinding handling, animations, and workspace layout in
the overview to match.
(This commit does not change the workspace switching indicator pending
finalization of what we want to do with that - it still shows workspaces
arranged vertically.)
https://bugzilla.gnome.org/show_bug.cgi?id=640996
St.Button 'clicked' signal now has two arguments, and because we are also
passing an action id as an argument to the _onActionInvoked() callback,
we need to have the number of the signal arguments reflected accurately in
the function arguments.
https://bugzilla.gnome.org/show_bug.cgi?id=641809
This makes the animation feel more stable and keeps the left-most item expanded
when you move the mouse to the left in the tray.
The following behavior details are implemented by this patch:
- we wait to collapse an expanded item till after the tray is hidden if
we are hiding the tray
- we don't collapse an expanded item if the summary notification associated
with it is being shown, unless a different summary item is hovered over
- we don't consider the mouse hovering over a summary notification as
hovering over the tray, which allows us to collapse an expanded summary
item if it is not associated with the summary notification being shown
https://bugzilla.gnome.org/show_bug.cgi?id=636930
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
It doesn't currently work, so hide it for now.
It's not clear it's going to stay around long term,
anyway. If it doesn't we can delete the code, then.
Otherwise, we can add the code back when we have
something that works.

Commit 91d8a32f25 let WindowClone forward the size-changed signal
of the "real" window, disconnecting the signal handler when the
clone is destroyed. In case the clone was destroyed due to the
MetaWindowActor being closed, this results in a warning
(gsignal.c:2392: instance `0x2a3fac0' has no handler with id `2955').
Handle the case where the original window is destroyed before its
clone.
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().
