more than one of them at the time.
* Changed ViewLayer::FindView() to FindViews() that collects all views
with the given flag set, not just the first one.
* Made ViewLayer::AttachedToWindow() and DetachFromWindow() virtual,
WorkspacesLayer now overloads them to register itself with the window and
the desktop.

next window to get focus after the current one is gone. This fixes the
strange behaviour when using right-click to send the current window to
the back.
* When FFM is active, Desktop::SendWindowBehind() will now choose the
new focus window to be the one under the mouse, overriding the focus
list.
* Desktop::SendWindowBehind() will now also call _SendFakeMouseMoved()
if necessary.
* Removed Desktop::fFocusFollowsMouse; it was not used or
maintained anywhere.
* Minor cleanup.

of the last focus.
* When choosing a new focus window, this list is now used to find the
new focus window instead of just choosing the next window in the
workspace list.
* With the normal mode mouse, this shouldn't change anything, but with
focus follows mouse turned on, this will behave much better if you
don't actually move the mouse - and it also fixes bug #1886.

of locking before processing the message (single/all window lock)
-> in most message cases, I could comment out the unlocking/locking which
switched to the different lock, because the required lock is now already held,
this removes some race conditions which were commented in the code already
* EventDispatcher::SetDragMessage() didn't lock the object, this would have
been bad if multiple windows tried to set a drag bitmap at once
* the Desktop object keeps track of mouse position and pressed buttons, so
that it doesn't need to lock the EventDispatcher for sending fake mouse
moves to windows on show/hide of windows (solves some cases of possible
dead locks with the new locking strategy)
* the keyboard EventFilter switches the current workspace asynchrnously from
the Desktop thread (another source of possible deadlocks)
* the "reader is trying to become writer" check in MultiLocker is only used
in DEBUG mode now
As a summary: It would be nice if ServerWindow used a readlock for all messages
it processes itself, and forwards all messages for which it needs a write lock
to the Desktop thread. All cases where either the Desktop or the ServerWindow
mess with the EventDispatcher are possible sources of deadlocks. This is solved
right now by making sure that the lock is released before using the
EventDispatcher.
I have not observed any deadlocks while switching workspaces and launching
many apps anymore, neither crashes. But I have not tested extensively except
for in the test environment. That being said, I could reproduce the problems
on first try before in Haiku.

a debugger call in _LaunchInputServer may be overkill, but at least you could
conceivably cleanly restart the machine in the debugger (I think.) Because
without the input_server the machine is pretty useless.

* BMenuWindow now makes its menu focus view, so that it can receive key events.
* Keyboard navigation doesn't work as it should though, that is bug #670 is
still valid - there should even be another recently opened bug about this,
but Trac obviously ate it :-/
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19152 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed the DesktopSettings lock itself - it's not really needed at all,
and causes some trouble with a clean locking design. This may even have
fixed bug #757, at least I couldn't reproduce it anymore.
* There is now a class for read-only access that requires you to have locked
the desktop (either read or write).
* There is now another class LockedDesktopSettings that allows you to set
settings (and only that) - when you're changing the settings, you must not
have read locked the desktop (ie. hold the single window lock). The class
will obtain a write lock, but write locks can be nested.
* Moved SetWorkspacesCount() into the Desktop class.

even redrawn :-)

* added a few very small changes to make the tab sliding work perfectly
* added a comment on the purpose of WindowLayer::fLastMousePosition and
how it is supposed to be used to have the mouse cursor stick to what
is being dragged
* TODO: the tab offset doesn't necessarily have to be on [0..1], as long
as we update it during window resizing to keep the relative position

Needs some cleanup, passed values should be inside [0:1].
Need to make sure changing the title doesn't reset the tab to left.

read-only area shared between the Desktop and all applications.
* Right now, this area only contains the desktop colors, ie. B_PANEL_BACKGROUND_COLOR
etc.; ui_color() no longer needs to ask the server for these colors.
* The ui_colors are now maintained by DesktopSettings, though ColorSet is still there.
* The default colors are now hardcoded once and for everyone in InterfaceDefs.h, ie.
the app_server uses them as well.
* Desktop::Init() can now also return an error (but that is not yet accounted for).
* Cleaned up InterfaceDefs.h.
* Fixed wrong include in moreUTF8.h.

to cut down on BRegion related allocations, cannot really tell
if it speeds things up
* used the new BRegion pool in WindowLayer and ViewLayer whereever
a BRegion was used on the stack
* fixed the debugging stuff in MultiLocker - it will get you into
the debugger if you
- try to nest read locks
- try to write lock when your are a reader already
- don't match up nested locks when your a writer
-> but only if you #define DEBUG 1 in the .cpp, is off by default now
* went over WindowLayer, ServerWindow, Desktop and a few other places
and fixed the locking for use with the MultiLocker, the "a reader can
not become a writer" is especially tricky, feel free to review the
changes
* activated the MultiLocker, I tested this quite a bit, if there are
problems simply turn on DEBUG and you should drop into the debugger
right where the problem is... hope all is good

a window is closed, too (only happened when a new window was shown
before). This is done via the new Desktop::_SendFakeMouseMoved()
method. This fixes bug #342.
* The MouseFilter now always sets Desktop::fWindowUnderMouse, so that
one can differentiate between no window under mouse, and decorator
under mouse.
* EventDispatcher::SendFakeMouseMoved() now expects a BMessenger instead
of an EventTarget as target - this guarantees that it can safely be
called with any window now (instead of only the current window).

can't move them to another workspace, and you currently don't see a
window moving that is not in the current workspace. (this fixes bug #135)
* Desktop::SetWindowBehind() didn't update the WorkspacesLayer.
* Changed Desktop::MoveWindowBy() to be able to move window on any workspace.

this saves us some locking headaches and solves a possible deadlock in
ServerApp::Activate().

windows to front (or minimize them).
* Desktop::ActivateWindow() no longer crashes in case the window to be activated
is not on the current workspace - instead, it doesn't do anything at this
point. IOW it doesn't handle workspace activation at all, yet.
* Renamed ServerWindow::GetWindowLayer() to ServerWindow::Window().

correctly when Tracker is not running; obviously, the background is cleared in
Tracker before it had the chance of changing the view color.
Maybe the app_server needs to detect the background view of the desktop and
change the view color manually :-/

used by the Deskbar (for "Hide All" and "Show All"). The latter doesn't work
correctly yet, though, it just maximizes all windows of that application.
* Added a TODO to ServerWindow AS_MINIMIZE_WINDOW on how to make it work correctly.

The settings are stored in B_USER_SETTINGS_DIRECTORY/system/app_server/workspaces.
They are currently saved as a flattened BMessage - we might want to switch to the
driver_settings format, though.

to delete them accidently :)
* You should no longer call HWInterface::SetCursor(), but the new Desktop::SetCursor()
if you need to change the cursor.

* Desktop::SetWindowFeel() is now working, but doesn't respect the window
position yet (ie. floating windows would have to be moved to front).
* WindowLayer::Workspaces() now always reflects exactly the lists it's in
(at least after Desktop::AddWindow() has been called). WindowList::AddWindow()
and RemoveWindow() now update this flag to be correct at all times.
* Fixed Desktop::_ChangeWindowWorkspaces() to not set the current workspace
for windows that are not on the current workspace, and vice versa.
It also would hide windows that were already hidden, and tried to show
windows that actually were hidden (did no other harm than triggering
a rebuild of the global clipping).
* Floating windows now work as expected.
* Desktop::SetFocusWindow() won't give a window focus that has a modal.
* Renamed OnWorkspace() to InWorkspace().
* ServerApp::InWorkspace() now works correctly, added ServerApp::Workspaces()
as well.
* WindowLayer::SubsetWorkspaces() returns the workspaces mask this modal or
floating window should be in.
* New window flag B_SAME_POSITION_IN_ALL_WORKSPACES should work as well.
* Floating and modal windows now have always set this flag.
* Added a WindowList::HasWindow() method.
* Desktop windows (windows with the desktop feel) can now have focus again
(I accidently broke that before).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15434 a95241bf-73f2-0310-859d-f6bbb57e9c96
has to be udpated anyway.
* some work towards being able to set a window's look/feel/flags on-the-fly.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15265 a95241bf-73f2-0310-859d-f6bbb57e9c96
This also allows the workspaces layer for these actions, which is now done as well.

Workspace class is a simple accessor to this class that takes care about
locking (currently, it's just the desktop lock, maybe it'll stay that way).
* WorkspacesLayer now displays the window thumbs again.

* Added Desktop::ShowWindow() and HideWindow().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15238 a95241bf-73f2-0310-859d-f6bbb57e9c96
* workspace switch and subset windows functionality temporarily removed
(away with that mess!).
* no more RevealWMState() - we now have methods like ActivateWindow()
and SendWindowBehind() that do all the work - just a little cleaner
and with less overhead.
* Workspace is now a pretty passive class - it only stores configurations
of the windows and screens.
* added an evil work-around for a locking problem (in RootLayer::_SetFocus()).
* I'll plan to move pretty much all of the remaining root layer functionality
to Desktop - so that the all regions lock is only held in case clipping
regions are affected.

* Removed keyboard handling code from RootLayer and Layer.
* Renamed Desktop::ActiveRootLayer() to RootLayer() as there is only one
root layer per desktop.

distribute any messages to the clients yet.
* removed the working thread from RootLayer - for now, its event handlers are
still called using input filters in the new event dispatcher, though (to
get things started).
* ServerApp is now using a BMessenger to identify its client, and no longer
stores the port/token separately.
* the input_server handshake is a bit simpler now, as it can now just reply
to the app_server message, removed unused code from ServerProtocol.h
* calmed down the MultiLocker (it always printed thread statistics on startup,
because it's compiled in debug mode).
* removed the cursor thread stuff from AppServer.cpp
* the new event dispatcher now uses a cursor thread when supported (only in
native mode, not in the test environment), although it improves cursor
movement under Qemu, the effect is not as good as expected - this might
need some more investigations (might just be a thread priority problem).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15012 a95241bf-73f2-0310-859d-f6bbb57e9c96

is missing), but it will get there :)

temporary handling code in the app_server.
* RootLayer no longer creates the input_server messaging port - this is now
the responsibility of the input_server.
* Moved AS_CREATE_[OFFSCREEN_]WINDOW from ServerApp::_MessageLooper() to
_DispatchMessage().
* The RootLayer thread is now started as soon as the input_server is there.
* removed or disabled any input_server stuff in the AppServer class.
* removed old message commmands to the app_server.
* Removed the R5_CURSOR_COMM and HAIKU_APPSERVER_COMM definitions: the
input_server is now automatically built correctly depending on the target.
* InputServer::EventLoop() plays now safe and checks for error conditions.
* InputServer::EnqueueDeviceMessage() seems to leak memory, added TODO about
this.
* InputServer event loop messaging uses ports for inner-app communication - why?
* The InputServer event loop thread is no longer killed on exit, it just quits
when its port is gone.
* Minor cleanup in input_server.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14949 a95241bf-73f2-0310-859d-f6bbb57e9c96
Moved AS_ACTIVATE_APP over to Desktop. _CursorThread() is currently dysfunctional (but not enabled anyway).
Minor cleanup (Desktop::WindowList() is now a BObjectList).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14599 a95241bf-73f2-0310-859d-f6bbb57e9c96
Maybe the CursorManager should be used to set the cursors directly instead of using
fDesktop->GetCursorManager.FindCursor() and then fDesktop->GetHWInterface()->SetCursor()
in ServerApp.cpp.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14033 a95241bf-73f2-0310-859d-f6bbb57e9c96
creation/deletion (and management) over to that class.
ServerApp now gets a desktop pointer, and no longer uses gDesktop.
Converted private MessageLooper::_MessagePort() to a public method MessagePort()
so that the looper can be addressed from elsewhere without using PostMessage().
Added a real basic message loop to MessageLooper::_MessageLoop().
BApplication now only asks the app_server to get its desktop object which should
now be used for everything that's not in the realm of the application.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13824 a95241bf-73f2-0310-859d-f6bbb57e9c96

No real message processing is done yet, though.

the desktop's settings, you have to do something like this:
DesktopSettings settings(desktop);
settings.SetMouseMode(mode);
The advantage of this is that this object is fully locked, and cannot lead to
corrupted settings anymore. Also, the settings will stay the same until you
delete the object again.
Updated all accesses to use this new API.
Removed no longer used FFM messages.
Implemented AS_{GET|SET}_MENU_INFO for future use.
