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.

627e06632a WindowServer: Don't crash when trying to open an empty menu. 2019-02-12 14:28:39 +01:00

ec7099dac3 WindowServer: Made a slightly nicer icon for the system menu. 2019-02-12 13:19:58 +01:00

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

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. :^)

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.

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.

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

3c863e0ffa WindowServer: Make automatic menu dismissal feel more "natural." 2019-02-11 13:59:26 +01:00

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.

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! :^)

caff611ca3 WindowServer: Tweak window title bar look. 2019-02-05 13:20:36 +01:00

38f589a9cb SharedGraphics: Add some useful painting helpers and make use of them. 2019-02-05 11:42:58 +01:00

cd1bbdf052 WindowServer: Make the window close button look a bit nicer. 2019-02-05 11:05:24 +01:00
Andreas Kling
11db8c1697 Add a simple close button ("X") to windows. 
Clicking the button generates a WindowCloseRequest event which the client app
then has to deal with. The default behavior for GWindow is to close() itself.

I also added a flag, GWindow::should_exit_event_loop_on_close() which does
what it sounds like it does.

This patch exposed some bugs in GWindow and GWidget teardown.

b1e054ffe8 Rename LizaBold to LizaRegular and LizaBlack to LizaBold. 
LizaRegular is quickly becoming my favorite bitmap font. It's so pretty :^)
 2019-02-05 09:08:25 +01:00
Andreas Kling
cacba45f1c LizaBold8x10: Import a bold variant of Liza8x10 and make it the default bold. 
Start using it right away for window titles.

5e9ba2ac84 Kernel: Rewrite ProcFS. 
Now the filesystem is generated on-the-fly instead of manually adding and
removing inodes as processes spawn and die.

The code is convoluted and bloated as I wrote it while sleepless. However,
it's still vastly better than the old ProcFS, so I'm committing it.

I also added /proc/PID/fd/N symlinks for each of a process's open fd's.

2a093ada33 WindowServer: Add some stripes to the window titles. 
I like the look of this right now. Maybe later I'll feel differently.

ffab6897aa Big, possibly complete sweep of naming changes. 2019-01-31 17:31:23 +01:00
Andreas Kling
027d26cd5d Add a String::format() and use that in place of ksprintf() in the Kernel. 
You're never gonna be right 100% of the time when guessing how much buffer
space you need. This avoids having to make that type of decision in a bunch
of cases. :^)

069d21ed7f Make buttons unpress when the cursor leaves the button rect. 
Implement this functionality by adding global cursor tracking.
It's currently only possible for one GWidget per GWindow to track the cursor.

9fa8d4e22f WindowServer: Rename the two painting phases. 
Work now happens in terms of two messages:

    - WM_ClientWantsToPaint
    - WM_ClientFinishedPaint

This feels fairly obvious compared to the old Paint/Invalidate.

244d5bcce1 WindowServer: More event -> message renaming. 2019-01-26 05:35:45 +01:00
Andreas Kling
bba21adae3 WindowServer: Rename WSEvent to WSMessage. 
Also do the same for WSMessageLoop and WSMessageReceiver. More to come.

5f14e22a31 WindowServer: Make dragging window frames look kinda cool. 2019-01-25 05:19:45 +01:00

0db72786cf Snazz up the windows with some title bar gradients. :^) 2019-01-25 05:02:32 +01:00

c6b7b92625 WindowServer: Put the desktop background color in a member. 2019-01-25 03:48:50 +01:00

a915dd7b27 WindowServer: Retain window backing stores while blitting them. 2019-01-25 03:07:55 +01:00
Andreas Kling
86eae0f8df Let userland retain the window backing store while drawing into it. 
To start painting, call:
gui$get_window_backing_store()

Then finish up with:
gui$release_window_backing_store()

Process will retain the underlying GraphicsBitmap behind the scenes.
This fixes racing between the WindowServer and GUI clients.

This patch also adds a WSWindowLocker that is exactly what it sounds like.

aa24547e12 Kernel: Finally stop exposing Region members to the public. 2019-01-24 18:09:46 +01:00
Andreas Kling
51595603bd WindowServer: Rename WSEvent subclasses WSFooEvent for consistency. 
Add a WSWindowInvalidationEvent that carries a rect instead of having an
awkward single-purpose rect in WSEvent.
Flesh out WSKeyEvent a bit more.

291922b1af WindowServer: Show PID and window ID in title bars for now. 
This is useful for debugging since I'm often wondering which process some
window belongs to (and what the window ID is.)
