09aaa41e62 SharedGraphics: Rework GraphicsBitmap::create_kernel_only() into create().
And just use mmap() to allocate the pixels.
2019-02-16 12:22:52 +01:00

4ea28bf0a5 Kernel: Add a simple shared memory API for two processes only.
And use this to implement shared bitmaps between WindowServer and clients.

468113422f Kernel: Add ioctls to BochsVGADevice for mode setting and page flipping.
Use these in WindowServer instead of poking at the BochsVGADevice directly.
2019-02-16 10:26:01 +01:00
Andreas Kling
799177feda Kernel: Make BochsVGADevice a BlockDevice and support mmapping it.
Currently you can only mmap the entire framebuffer.
Using this when starting up the WindowServer gets us yet another step
closer towards it moving into userspace. :^)

fbcc8ab840 WindowServer: Slurp all available client messages when checking them.
We were reading one client message per client per event loop iteration.
That was not very snappy. Make the sockets non-blocking and read() until
there are no messages left.

It would be even better to make as few calls to read() as possible to
reduce context switching, but this is already a huge improvement.

29c49356e3 WindowServer: Rename GUI_Foo to WSAPI_Foo. 2019-02-15 09:17:18 +01:00

a54cd84c59 Move WindowServer API types header into WindowServer/. 2019-02-15 09:14:21 +01:00

18210c606d Kernel: Remove GUIEventDevice.
It's no longer used since all communication now happens across sockets. :^)

bf58241c11 Port the WindowServer and LibGUI to communicate through local sockets.
This is really cool! :^)

Apps currently refuse to start if the WindowServer isn't listening on the
socket in /wsportal. This makes sense, but I guess it would also be nice
to have some sort of "wait for server on startup" mode.

This has performance issues, and I'll work on those, but this stuff seems
to actually work and I'm very happy with that.

dc200923f2 WindowServer: Ignore attempts to make menu windows the active window. 2019-02-14 10:56:45 +01:00
Andreas Kling
7c53171b0a WindowServer: Add debug logging if we try to activate a client-less window. 2019-02-14 10:53:28 +01:00

2733a788eb WindowServer: Make MenuBar unaware of Process. 2019-02-14 10:49:59 +01:00

7723c06f27 WindowServer: Make WSMenu use WSClientConnection::post_message(). 2019-02-14 10:45:27 +01:00
Andreas Kling
c4703bedea WindowServer: Get rid of the WSWindow lock now that accesses are serial. 2019-02-14 10:35:56 +01:00
Andreas Kling
e5df2a5d5b WindowServer: Post error if trying to destroy non-existent menubar. 2019-02-14 10:31:39 +01:00
Andreas Kling
5d30c6b00c WindowServer: Add WSClientConnection::create_bitmap().
There we go. Now WSWindow doesn't know about Process at all.
2019-02-14 10:29:17 +01:00
Andreas Kling
9ab9734da0 WindowServer: Add WSClientConnection::post_message().
This way WSWindow doesn't have to grab at the Process.
2019-02-14 10:15:49 +01:00

222a6f7bbc WindowServer: Post error messages to clients on protocol failure. 2019-02-14 09:32:34 +01:00

28da956a12 WindowServer: Refactor WSClientConnection to have one function per request.
This is a lot nicer than the big switch full of code. This stuff has a bit
of a "please generate me instead" vibe to it, but I need to mess around with
it some more to figure out what the needs are.

This patch also unbreaks global cursor tracking, which was forgotten in the
big messaging refactoring.
2019-02-14 08:43:29 +01:00

aa7947c889 WindowServer: Add WSClientConnection class to manage an individual client.
This makes both object lifetimes and object ID's a lot easier to understand.

f529b845ec WindowServer: Convert entire API to be message-based.
One big step towards userspace WindowServer. :^)
2019-02-14 01:21:32 +01:00
Andreas Kling
ef4e9860fd WindowServer: Convert the remaining menu APIs into messages. 2019-02-13 21:47:14 +01:00
Andreas Kling
cf432b4c3d WindowServer: Refactor more of the menu APIs to be message-based.
This is all pretty verbose but I can whittle it down later. :^)
2019-02-13 18:49:23 +01:00

fbbf57b61c Rename GUI_Event to GUI_ServerMessage.
Now that communication is becoming bidirectional, "event" is no longer right.
2019-02-13 17:59:38 +01:00
Andreas Kling
4f98a35beb WindowServer: Begin refactoring towards a fully asynchronous protocol.
In order to move the WindowServer to userspace, I have to eliminate its
dependence on system call facilities. The communication channel with each
client needs to be message-based in both directions.
2019-02-13 17:54:30 +01:00
Andreas Kling
1d758fd2ce WindowServer: Don't spawn new processes with WindowServer as parent.
I don't want to have to wait() on them from the WindowServer. Let's just set
new processes free and someone else will take care of them.
2019-02-13 09:53:21 +01:00
Andreas Kling
269f9ae524 WindowServer: Forgot to actually set 'had_any_timer' after we had any timer. 2019-02-13 09:38:32 +01:00
Andreas Kling
c5a00a56c8 WindowServer: Put a clock in the top right corner of the screen.
This way we don't even need the Clock app anymore. Very cool :^)

cac8153436 WindowServer: Try out a new IterationDecision thing for lambda iteration. 2019-02-13 01:04:11 +01:00
Andreas Kling
732f273949 WindowServer: Switch menubar based on the currently active window. 2019-02-13 00:19:21 +01:00
Andreas Kling
4f33fb3a1a WindowServer: Process window mouse events in the correct z-order. 2019-02-12 23:56:19 +01:00
Andreas Kling
1d7fc866ee WindowServer: Menu windows shouldn't steal focus when clicked. 2019-02-12 16:34:47 +01:00
Andreas Kling
d74b131c27 Add a little About app and hook it up to the system menu's "About..." entry.
Added icons and customizable text alignment to GLabel.
2019-02-12 15:23:07 +01:00

627e06632a WindowServer: Don't crash when trying to open an empty menu. 2019-02-12 14:28:39 +01:00
Andreas Kling
ec7099dac3 WindowServer: Made a slightly nicer icon for the system menu. 2019-02-12 13:19:58 +01:00
Andreas Kling
2b94b54640 WindowServer: Draw menu windows above normal windows. 2019-02-12 13:04:54 +01:00
Andreas Kling
7ce15f1c54 Fix some compilation warnings. 2019-02-12 12:11:22 +01:00
Andreas Kling
c61f9eba61 WindowServer: Add a WSWindowType enum.
So far there's only Normal and Menu. Maybe we'll need more later.
2019-02-12 11:53:45 +01:00
Andreas Kling
7def86c86d WindowServer: Send all mouse events inside the menubar rect to the menubar. 2019-02-12 10:47:02 +01:00
Andreas Kling
e03af1e8b9 WindowServer: Make it possible to launch a terminal from the system menu. 2019-02-12 10:45:09 +01:00
Andreas Kling
4b8133e925 WindowServer: Clean up any menu objects on process exit.
..and now that this works, implement the Quit menu action in Terminal. :^)
2019-02-12 10:41:09 +01:00
Andreas Kling
db98327bdc Plumb menu item activation events from WindowServer to clients.
GMenu now has an "on_item_activation" callback that fires whenever one
of its items are activated. The menu item identifier is used to distinguish
between items.

Use this to implement font switching in Terminal. :^)
2019-02-12 10:08:35 +01:00
Andreas Kling
9c1c885483 WindowServer: Add locking and fix coalesced invalidation race.
WSWindowManager::invalidate() had a bug where it would mark the entire screen
rect as dirty, but it wouldn't scheduled a deferred recompose.

This would cause any subsequent calls to invalidate(Rect) to be coalesced
with the pending compose, but the pending compose never happened.
2019-02-12 09:25:50 +01:00
Andreas Kling
5cd588a497 WindowServer: Always include the system menu in the menubar.
Solve this by adding a for_each_active_menubar_menu() iteration helper that
automagically visits the system menu before the current menubar's menus.
2019-02-12 08:49:07 +01:00
Andreas Kling
15b4c9f9f1 WindowServer: More work on the menu system.
Menus are now tied to a Process (by WeakPtr.) This will allow us to pass
notifications to the correct event stream.
2019-02-12 08:39:19 +01:00
Andreas Kling
133706d697 Add API's and plumbing for WindowServer clients to make menus. 2019-02-12 00:52:19 +01:00
Andreas Kling
bb31d961b4 WindowServer: Let's call the default menu "Dummy" for now. 2019-02-11 15:39:19 +01:00
Andreas Kling
8d0bfa62fd WindowServer: Add a bunch of horizontal padding to menu items.
All right, this looks a lot nicer. :^)
2019-02-11 14:14:49 +01:00
Andreas Kling
3c863e0ffa WindowServer: Make automatic menu dismissal feel more "natural." 2019-02-11 13:59:26 +01:00
Andreas Kling
43d9994d93 WindowServer: Oops, we have to keep processing WSMessages with !m_process.
Otherwise we'll never handle WM_DestroyWindow and the window sticks around.
