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.

78fc7a9ef2 WindowServer: Menu windows should be at least as wide as their menubar rects. 2019-02-11 10:19:56 +01:00

5f288014d4 WindowServer: More work on menus. 2019-02-11 10:08:54 +01:00

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.

7abef6ba9e LibGUI: Put some logspam behind debugging macros. 2019-02-11 08:27:13 +01:00

6b2d2cc5e3 Create /dev files for null, full, zero and random. 2019-02-11 06:59:28 +01:00

1511afc4e2 LibGUI: Add GWindow::move_to(). 2019-02-11 06:09:54 +01:00

18962bf102 Kernel: Oops, the kernel image access validator thought 0x0 was allowed. 
We forgot to look at the ELF segment type when validating accesses.
We should only consider accesses inside non-empty LOAD segments.

7014daa235 Kernel: Add an LRU block cache. 
This papers over some of the incredibly inefficient access patterns in the
Ext2FS implementation for a while longer. :^)

052a101cc5 Terminal: Fix lagged full flush after scrolling the whole buffer. 
Now that we're using the lazy rendering model of LibGUI, we can't wait until
paint_event() to decide how much we want to update. :^)
 2019-02-10 14:47:09 +01:00

08322ab8e1 LibGUI: Coalesce update rects at the GWindow level. 2019-02-10 14:46:43 +01:00

53d34a0885 Port Terminal to LibGUI. 
To facilitate listening for action on arbitrary file descriptors,
I've added a GNotifier class. It's quite simple but very useful:

GNotifier notifier(fd, GNotifier::Read);
notifier.on_ready_to_read = [this] (GNotifier& fd) {
    // read from fd or whatever else you like :^)
};

The callback will get invoked by GEventLoop when select() says we
have something to read on the fd.

ae4811fbae ProcFS: Show region flags in /proc/PID/vm 
It's useful to be able to see the readable, writable and bitmap flags.
 2019-02-10 13:02:38 +01:00
Andreas Kling
6103e374cc Kernel: Drop the "helper" region after ELF load is finished. 
The individual segment mappings will keep the VMObject alive.
 2019-02-10 12:47:15 +01:00

d333013a54 LibGUI: Support horizontal GScrollBars as well. 2019-02-10 12:27:21 +01:00
Andreas Kling
8313ce57dc LibGUI: Improve GScrollBar button look a bit. 
The arrows look better when they're sharp. :^)

ddd580c30f SharedGraphics: Tighten clip when blitting without alpha. 
Also don't try to clean up the Painter's window backing store in ~Painter()
if we don't actually have a window backing store.

9860e55047 Kernel: Put page fault logspam behind PAGE_FAULT_DEBUG. 2019-02-10 11:37:59 +01:00
Andreas Kling
5e8d6b1bf4 Base: Rename /users to /home. 
I didn't like seeing /users next to /usr. /home looks nicer.

2def3d8d3f LibGUI: Start adding an automatic widget layout system. 
My needs are really quite simple, so I'm just going to add what I need
as I go along. The first thing I needed was a simple box layout with
widgets being able to say whether they prefer fixed or fill for both
their vertical and horizontal sizes.

I also made a simple GStatusBar so FileManager can show how many bytes
worth of files are in the current directory.

2cf1dd5b6f Move apps into a top-level Applications/ directory. 2019-02-10 08:35:01 +01:00

29f2a22d34 LibGUI: Minor cleanup in GScrollBar. 2019-02-10 08:23:03 +01:00
Andreas Kling
546946775b Base: Add an app icon for FileManager. 2019-02-10 07:48:54 +01:00

4a7120afe1 SharedGraphics: Fix blitting GraphicsBitmaps with clipping enabled. 2019-02-10 07:46:29 +01:00

f7831f8c76 LibGUI: Draw GScrollBar buttons with a disabled look when appropriate. 2019-02-10 07:37:02 +01:00
Andreas Kling
1e8e4e9af2 Launcher: Add button for FileManager. 2019-02-10 07:36:37 +01:00
Andreas Kling
e354c08c98 LibGUI: Share code for widget rendering styles in a GStyle class. 
Since GScrollBar wants its internal buttons to look like GButtons,
let's share the painting code between them.
 2019-02-10 07:11:01 +01:00
Andreas Kling
9ea2131adf LibGUI: Support dragging the GScrollBar scrubber. 
This was pleasantly easy to implement with the global mouse tracking. :^)
 2019-02-10 06:51:01 +01:00

6b8af2f33a Base: Improved FontEditor icon. 2019-02-10 06:30:16 +01:00

464873f8b5 LibGUI: Draw some cute arrows on the GScrollBar buttons. 2019-02-10 06:10:27 +01:00

cc04ba9cc9 ProcFS: /proc/sys entries should always be regular 644 files. 2019-02-10 06:10:01 +01:00
Andreas Kling
5bd363c4bb LibGUI: Widget updates should invalidate their window-relative rect. 2019-02-09 14:30:05 +01:00
Andreas Kling
6a3ff7efc5 GScrollBar: Start looking a bit more like a proper scrollbar. 
And hook up FileManager's DirectoryView with its scrollbar so it actually
causes the directory view to shift up and down. Very cool. :^)
 2019-02-09 11:29:59 +01:00
Andreas Kling
1f355f2a79 LibGUI: Start working on a GScrollBar. 
This widget is far from finished, but it's off to a good start.
Also added a GResizeEvent and GWidget::resize_event() so that widgets
can react to being resized.
 2019-02-09 11:19:38 +01:00

4d5fe39494 FileManager: Start building a file manager. 2019-02-09 09:22:04 +01:00

8ae7be611a LibC: closedir() should free the readdir() buffer and the DIR itself. 2019-02-09 09:08:27 +01:00
Andreas Kling
c4e984ca49 Kernel: Allow mmap() with a size that's not a multiple of page size. 
We just round it up to the next multiple of page size anyway.
 2019-02-09 08:44:46 +01:00

fa241747af Kernel: When donating ticks to a lock holder, cap the donation. 
When donating ticks to a lock holder, never donate more ticks than
that process would normally get from the scheduler.
 2019-02-08 22:06:30 +01:00
Andreas Kling
cb6e852620 SharedGraphics: Don't eagerly commit mmap'ed font files in kernel. 
Just let the page fault handler do its thing. Anytime we can avoid
loading some pages from disk, that's a good thing.
 2019-02-08 21:59:06 +01:00

b365ad4aef LibC: fgetc() and pals should return EOF on error or EOF. 
This was the reason that "uname | figlet" wasn't working. There was nothing
wrong with the pipe like I kept thinking.
 2019-02-08 17:49:54 +01:00

c9aaf74e1d LibC: Add some more fake termcap entries to silence bash-5.0. 2019-02-08 17:49:25 +01:00

6274208eb9 Ext2FS: Fix bitmap overrun when reaching outside the first block group. 2019-02-08 17:14:51 +01:00

a6f9ddbb58 Let's have two wallpapers installed so we can test switching. 2019-02-08 17:14:47 +01:00
Andreas Kling
cf58b76210 SharedGraphics: GraphicsBitmap::load_from_file() should be allowed to fail. 
It's okay if it fails to load a bitmap in kernel space. Just return nullptr.
 2019-02-08 16:49:05 +01:00
Andreas Kling
d4ba155711 Kernel: Break retain cycle between Inode and VMObject. 
There's no need for an Inode to keep its corresponding VMObject alive.
Obviously there are huge benefits to keeping a filesystem cache,
but leaking everything is hardly the right strategy. :^)

e1be5a468d Userland: Add a /bin/pape helper program to switch the desktop wallpaper. 2019-02-08 16:22:54 +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
e78e032c19 Add a little ReadMe. 2019-02-08 11:06:34 +01:00

f8fc892bac Remove _fs_contents.stock and generate it on the fly instead. 2019-02-08 09:56:39 +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. :^)
