85afd1b6f871d471fdff1980134676a5f1690525 13-May-2012 Dianne Hackborn <hackbod@google.com> Implement new window cropping.

The window manager now performs the crop internally, evaluating
it every animation from, to be able to update it along with
the surface position.

This will be used to determine which parts of a window a completely
hidden by system UI elements (status bar, nav bar, system bar) so
that they can be clipped out from rendering.

Make surface management between SurfaceView and the window manager
much more controlled, to ensure that SurfaceView always gets to report
the current surface is destroyed before the window manager actually
destroys it.

Also a small tweak to allow windows that have a wallpaper background
to still have a preview window. This makes launching home after it
has been killed feel much more responsive.

This cleans up how ui flags are managed between the client and window manager.
It still reports the global UI mode state to the callback, but we now only clear
certain flags when the system goes out of a state (currently this just means the
hide nav bar mode), and don't corrupt other flags in the application when the
global state changes.

Also introduces a sequence number between the app and window manager, to avoid
using bad old data coming from the app during these transitions.

02d2b3ba9ba830a8147db2739613f7bbb2d0fcbf 11-Jan-2011 Christopher Tate <ctate@google.com> API CHANGE: startDrag() now takes "int flags" instead of "boolean localOnly"

There will be, in the future, a flag (View.DRAG_FLAG_GLOBAL) that means
for the drag to be cross-application. For now that flag constant is @hide
and furthermore the server-side implementation strips it, enforcing
local-only drags.

DragEvent.getResult() returns 'true' if the drop was ultimately accepted;
false otherwise. The validity of this datum is only guaranteed when the
DragEvent's action verb is ACTION_DRAG_ENDED.

Also fixes the drag-start timeout handling (though the offending app is
not yet officially declared ANR).

Implements bug 3097807

a53146c5569f8ff5f7eb55e9ad35d23ddacf2add 07-Sep-2010 Christopher Tate <ctate@google.com> Drag/drop APIs and infrastructure

A View initiates a drag-and-drop operation (hereafter just called a "drag")
by calling its startDrag(ClipData) method. Within the processing of that
call, two callbacks are made into the originating View. The first is to
onMeasureDragThumbnail(). Similarly to the core onMeasure() method, this
callback must respond by calling setDragThumbnailDimension(width, height) to
declare the size of the drag thumbnail image that should be used. Following
this, the View's onDrawDragThumbnail(canvas) method will be invoked to
actually produce the bits of the thumbnail image.

If all goes well, startDrag() will return 'true', and the drag is off and
running. (The other arguments to startDrag() provide reconciliation between
the current finger position and where the thumbnail should be placed on
the screen relative to it.)

Potential receipients of the ClipData behind the drag are notified by a
new dispatch mechanism, roughly parallel to motion event dispatch. The core
routine is the View's onDragEvent(event) callback, with the mechanics of
dispatch itself being routed through dispatchDragEvent(event) -- as in
the case of motion events, the dispatch logic is in ViewGroup, with leaf
View objects not needing to consider the dispatch flow.

Several different event 'actions' are delivered through this dispatch
mechanism:

ACTION_DRAG_STARTED: this event is propagated to every View in every window
(including windows created during the course of a drag). It serves as a
global notification that a drag has started with a payload whose matching
ClipDescription is supplied with the event. A View that is prepared to
consume the data described in this event should return 'true' from their
onDragEvent() method, and ideally will also make some visible on-screen
indication that they are a potential target of the drop.

ACTION_DRAG_ENTERED: this event is sent once when the drag point
enters the View's bounds. It is an opportunity for the View to set up
feedback that they are the one who will see the drop if the finger goes
up now.

ACTION_DRAG_LOCATION: when the drag point is over a given View, that
View will receive a stream of DRAG_LOCATION events, providing an
opportunity for the View to show visual feedback tied to the drag point.

ACTION_DRAG_EXITED: like DRAG_ENTERED, but called when the drag point
leaves the View's bounds. The View should undo any visuals meant to
emphasize their being the hovered-over target.

ACTION_DROP: when the drag ends at a given point, the View under that
point is sent this event, with the full ClipData of the payload.

ACTION_DRAG_ENDED: paralleling the DRAG_STARTED action, this is the global
broadcast that the drag has ended and all Views should return to their
normal visual state. This happens after the DROP event.

Removed old input dispatch code.
Refactored the policy callbacks.
Pushed a tiny bit of the power manager state down to native.
Fixed long press on MENU.
Made the virtual key detection and cancelation a bit more precise.

46b9ac0ae2162309774a7478cd9d4e578747bfc2 23-Apr-2010 Jeff Brown <jeffbrown@google.com> Native input dispatch rewrite work in progress.

The old dispatch mechanism has been left in place and continues to
be used by default for now. To enable native input dispatch,
edit the ENABLE_NATIVE_DISPATCH constant in WindowManagerPolicy.

Includes part of the new input event NDK API. Some details TBD.

To wire up input dispatch, as the ViewRoot adds a window to the
window session it receives an InputChannel object as an output
argument. The InputChannel encapsulates the file descriptors for a
shared memory region and two pipe end-points. The ViewRoot then
provides the InputChannel to the InputQueue. Behind the
scenes, InputQueue simply attaches handlers to the native PollLoop object
that underlies the MessageQueue. This way MessageQueue doesn't need
to know anything about input dispatch per-se, it just exposes (in native
code) a PollLoop that other components can use to monitor file descriptor
state changes.

There can be zero or more targets for any given input event. Each
input target is specified by its input channel and some parameters
including flags, an X/Y coordinate offset, and the dispatch timeout.
An input target can request either synchronous dispatch (for foreground apps)
or asynchronous dispatch (fire-and-forget for wallpapers and "outside"
targets). Currently, finding the appropriate input targets for an event
requires a call back into the WindowManagerServer from native code.
In the future this will be refactored to avoid most of these callbacks
except as required to handle pending focus transitions.

End-to-end event dispatch mostly works!

To do: event injection, rate limiting, ANRs, testing, optimization, etc.

Well, mostly. There is still a problem here where the first time
you show the lock screen it just doesn't draw itself. I assume
this is something breaking in the view hierarchy as it floounders
around removing and adding new views as it is first being shown...
but no idea at this point what is the actual case.

19382ac1a4e4e7c23a1346d299368763f149de9c 12-Sep-2009 Dianne Hackborn <hackbod@google.com> Some optizations to wallpaper drawing/scrolling.

First, fix some issues with the final wallpaper bitmap
we use: ensure it is always 16bpp, and make sure dithering
of its bitmap is turned off. We take of dithering
when loading, to make sure we don't use it when drawing.

Also add new APIs to return the wallpaper with the equivalent
of Launcher's old FastBitmapDrawable. As doing this, also load
the default wallpaper the same way as custom ones, taking care to
resize it as needed at load time.

Finally implement a mechanism for the window manager to wait
for the wallpaper to redraw at its new position before returning
from the application's call to change the offset. This ensures
that the wallpaper better tracks the application. Note that there
is a timeout in this wait that is relatively short, and if it
expires we will run for a while without waiting.

This currently only works for a wallpaper that is larger than the
screen. Set the scroll position with the new wallpaper API. Right
now only does jump scrolls.
