  <shortdesc xml:lang="en">Next generation GNOME desktop shell</shortdesc>
-  <description>GNOME Shell provides core user interface functions for the GNOME 3
-desktop, like switching to windows and launching applications.
-GNOME Shell takes advantage of the capabilities of modern graphics
-hardware and introduces innovative user interface concepts to
-provide a visually attractive and easy to use experience.
-
-Tarball releases are provided largely for distributions to build
-packages. If you are interested in building GNOME Shell from source,
-we would recommend building from version control using the build
-script described at:
-
- http://live.gnome.org/GnomeShell
-
-Not only will that give you the very latest version of this rapidly
-changing project, it will be much easier than get GNOME Shell and
-its dependencies to build from tarballs.</description>

Florian Müllner	a66af6fbac	overview: Update animation Update the animation on entering/leaving the overview to only zoom the window previews and fade other elements. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:13 +01:00
Florian Müllner	1bbc138ed2	dash: Improve DND to dash and allow reordering Show a positional indicator where a new favorite will be added and make the favorites re-orderable. Also allow the removal of favorites using drag-and-drop according to the mockups. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:13 +01:00
Florian Müllner	868d4756e4	workspaces: Change handling of window-drag signals Delegate the emission of the window-drag-begin/window-drag-end signals to overview functions, as done already for other items. This will enable objects to react to those signals without having access to the workspace objects / the workspaces view. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:13 +01:00
Florian Müllner	dfa3be59dc	search-display: Change the default display to use iconGrid Current mockups display all search results as icons as used by application results, so change the default result display to use iconGrid/BaseIcon. Remove the custom application results display, as it is no longer needed. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:13 +01:00
Florian Müllner	62677336a5	overview: Add ViewSelector to the overview Add the view selector and adjust the positioning of elements in the overview. Unlike the old dash, the view selector is made public to indicate that extensions may add additional views or search providers. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:06 +01:00
Florian Müllner	264a82cbfc	workspaces: Rework workspace controls for the view selector As workspaces will appear as a particular view in the view selector, merge WorkspacesControls and WorkspacesManager to control workspaces and related controls, so that a single actor can be added to the selector instead of positioning the elements from the overview. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:06 +01:00
Florian Müllner	f8cfd9f903	workspaces-view: Swap workspace ordering for RTL locales Make the first workspace the right-most one in RTL locales, as one would expect. Update all dragging/scrolling functions to behave correctly. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:06 +01:00
Florian Müllner	13f8cd3bcf	workspaces-view: Remove MosaicView The new layout does no longer support view switching, so merge GenericWorkspacesView and SingleView, and remove MosaicView. Also rename or remove workspace properties and functions which are now unused. The grid will have a comeback with the new DND behavior. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:06 +01:00
Florian Müllner	e1f336374b	app-display: Slight cleanup and style update Being no longer an independent menu pane, both the toggle() and close() functions are no longer needed, and the view's structure can be simplified a bit. Also update the style to fit into the view selector. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:06 +01:00
Florian Müllner	0ba1387d19	Fake workspaces tab https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:06 +01:00
Florian Müllner	8832ce3a2b	view-selector: Add keyboard shortcut for view switching As the view selector is a tabbed interface, use the default keyboard shortcut of Ctrl-PageUp/PageDown of GtkNotebook for switching between views. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:06 +01:00
Florian Müllner	91d7a022a9	view-selector: Move search logic into SearchTab The view selector should only deal with view switching, so move the logic to deal with search (find-as-you-type, cancelling a search, navigating/activating results) into the SearchTab. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:11:03 +01:00
Florian Müllner	95d15725fc	Use the old dash code to implement the view selector The view selector is a tabbed interface with a search entry. Starting a search switches focus to the results' tab, ending a search moves the focus back to the previously selected tab. Activating a normal tab while a search is active cancels the search. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 05:10:21 +01:00
Florian Müllner	bb2b7d83af	search-display: Move SearchResults to a separate file With the new layout, search results will be displayed in an independent view like window previews, applications and possible future additions; it does not make much sense keeping it with the switching logic, so move the code to its own file. Also remove the dash-prefix from the relevant style classes. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 00:13:51 +01:00
Florian Müllner	0abac6f67d	dash: Move padding into the icon for Fittsability With this change, the icons' reactive area extends to the screen edge, making them good targets according to Fitts' law. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 00:13:51 +01:00
Florian Müllner	e00398e2ac	dash: Reimplement the dash based on AppWell code The new dash implementation is a single-column vertical sidebar, whose items are scaled dynamically to fit the available height. If the height is still exceeded after scaling down to a minimum item size, excess items are cut off. The now unused old dash implementation is renamed to OldDash, as its code will be used as a base for the new view selector element. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 00:13:51 +01:00
Florian Müllner	0f19492545	linear-view: Remove NewWorkspaceArea As the button to add workspaces will move to the same position as the new workspace drop area in drag mode, the latter is redundant and can be removed. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 00:13:51 +01:00
Florian Müllner	9d46a6ceea	linear-view: Remove shadows when zoomed out Overlaying inactive workspaces with a gradient to fade out the actors does no longer work when re-using the normal desktop background. If we keep the current DND behavior, we probably want to implement a real fade effect - for now, just remove the visually disruptive shadows. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 00:13:51 +01:00
Florian Müllner	6432de95cc	overview: Do not zoom the desktop background While scaling the desktop background with the window previews represents workspaces quite intuitively, the approach is not without problems. As window previews in the overview behave quite differently to "real" windows, the representation of workspaces as miniature versions of "real" workspaces is flawed. The scaling also makes the transitions to and from the overview much more visually expensive, without adding much benefit. Leaving the background in place provides more visual stability to the transitions and emphasizes the distinctive behavior of elements in the overview. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-19 00:13:46 +01:00
Florian Müllner	738fc375c0	overview: Replace InfoBar with message tray notifications The layout of recent mockups occupies the space previously reserved for the info bar with the view selector. As the bar's purpose is mainly to provide the user with feedback, it makes sense to use the existing message tray facility instead of moving the bar elsewhere. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-18 20:35:55 +01:00
Florian Müllner	4e9a530a64	linear-view: Remove the scrollbar The scrollbar is the main culprit for cluttered controls in the linear view - all its functionality is already provided by the workspace indicators, so it is save to remove the scrollbar in order to clean up the interface. https://bugzilla.gnome.org/show_bug.cgi?id=634948	2010-11-18 20:35:55 +01:00
