fa452fadca WindowServer: Let menu objects reference the WSClientConnection by pointer. 
Since these are owner/ownee relationships, there's no need for indirection.

9a39c01551 WindowServer: WSWindow can have a pointer to the client rather than an ID. 
Since WSWindows are owned by WSConnectionClients, it's fine for them to just
reference the client directly.

82768e7ac5 WindowServer: Move video mode setup to WSScreen. 2019-02-17 01:43:01 +01:00

3eb6c22a22 WindowServer: Make the menubar clock work again in the post-kernel world. 
This is actually so much better. Grabbing directly at the RTC was silly. :^)

640360e958 Move WindowServer to userspace. 
This is a monster patch that required changing a whole bunch of things.
There are performance and stability issues all over the place, but it works.
Pretty cool, I have to admit :^)

468113422f Kernel: Add ioctls to BochsVGADevice for mode setting and page flipping. 
Use these in WindowServer instead of poking at the BochsVGADevice directly.

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
Andreas Kling
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
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

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. :^)

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.

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

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

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
c61f9eba61 WindowServer: Add a WSWindowType enum. 
So far there's only Normal and Menu. Maybe we'll need more later.

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. :^)

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.

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

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
3c863e0ffa WindowServer: Make automatic menu dismissal feel more "natural." 2019-02-11 13:59:26 +01:00
Andreas Kling
f7b25773ab WindowServer: Let's have a cute little symbol for the system menu. 2019-02-11 13:00:41 +01:00
Andreas Kling
e6de6c4f45 WindowServer: Don't keep menu items in hovered state after the cursor leaves. 2019-02-11 11:06:41 +01:00
Andreas Kling
6dd1a1f26d WindowServer: Switch current menu if hovering over another menu with button. 2019-02-11 10:59:48 +01:00
Andreas Kling
145aa27b8f WindowServer: Give menu items an identifier field and add a simple callback. 
Eventually these identifiers will be sent to the userspace client who created
the menu. None of that is hooked up yet though.
 2019-02-11 10:55:02 +01:00
Andreas Kling
5f288014d4 WindowServer: More work on menus. 2019-02-11 10:08:54 +01:00
Andreas Kling
443b043b49 WindowServer: Start implementing a menu system. 
I'm going with a global top-of-the-screen menu instead of per-window menus.
The basic idea is that menus will live in the WindowServer and clients can
create menus via WindowServer requests.

a6f9ddbb58 Let's have two wallpapers installed so we can test switching. 2019-02-08 17:14:47 +01:00
Andreas Kling
33d34d9b26 Kernel: Use a Lockable<bool> for sysctl booleans as well. 2019-02-08 16:18:24 +01:00
Andreas Kling
7a996e608c WindowServer: Allow changing the desktop wallpaper through a sysctl. 
Just write the path of your new wallpaper to /proc/sys/wm_wallpaper. :^)
 2019-02-08 09:49:09 +01:00
Andreas Kling
90d3375dc2 WindowServer: Support desktop wallpapers. 
For now, you don't get to choose the wallpaper, but it's still pretty cool.

5582a0a254 Kernel: When a lock is busy, donate remaining process ticks to lock holder. 
Since we know who's holding the lock, and we're gonna have to yield anyway,
we can just ask the scheduler to donate any remaining ticks to that process.

443d1c2237 WindowServer: Coordinate double-buffering with the BochsVGA card. 
Use the BochsVGA card's virtual-height + virtual-y features to implement
a "hardware double buffering" type scheme.

This is a performance degradation since we now draw a bunch more than before.
But there's also no tearing or cursor flickering. I'm gonna commit this and
try to improve upon it. :^)

a1b63bb6d4 Bootloader: Locate the kernel's data segment and clear it. 
This was a constant source of stupid bugs and I kept postponing it because
I wasn't in the mood to write assembly code. Until now! :^)
