26a9d662f4 Kernel+WindowServer: Move mouse input signal parsing to kernel driver. 
It was silly for the WindowServer to have to know anything about the
format of PS/2 mouse packets.

This patch also enables use of the middle mouse button.

1cc32ebc7e Kernel: Remove "requested wakeups" feature. 
I only needed this to support the WindowServer living inside the kernel.
Now that it's been migrated to userspace, this can go. :^)

91031346e5 Kernel: More signal handling improvements. 
Finally fixed the weird flaky crashing when resizing Terminal windows.
It was because we were dispatching a signal to "current" from the scheduler.
Yet another thing I dislike about even having a "current" process while
we're in the scheduler. Not sure yet how to fix this.

Let the signal handler's kernel stack be a kmalloc() allocation for now.
Once we can do allocation of consecutive physical pages in the supervisor
memory region, we can use that for all types of kernel stacks.

086a0fc969 LibGUI: Let GApplication::exec() call exit() instead of returning to main(). 
This sidesteps the problem of having various things on the heap that don't
get torn down. It's obviously not a great solution, but it'll work for now.

9e1fcb74a2 Kernel: Returning from a signal handler reset the signal mask correctly. 
We were setting the handled signal number as the new signal mask, oops.

251293f2e1 Kernel: Block a signal from being dispatched again until handler returns. 
We don't handle nesting yet, but this is a step in the right direction.

b67d0a3632 WindowServer: Determine resizing "hot corner" based on window's outer rect. 2019-03-04 11:34:25 +01:00

67fc42f64e Kernel: SIGCONT should unblock a blocked process. 
Otherwise we might stay in BlockedSignal state forever. Unblocking just
means that the current syscall may fail with EINTR.

ac2a3f7fdf GTableView: Make the last column header separator look right. 2019-03-04 10:26:16 +01:00
Andreas Kling
f91a20f9d0 LibGUI: Unbreak clearing GTableView selection by clicking outside items. 
Also, clicking on the column headers should not clear selection.

ef4d517429 LibGUI: Tweak focus appearance and add it to GTableView. 2019-03-04 10:12:09 +01:00

5c27e74fac WindowServer: Add a window switcher. 
This needs some work on the window ordering and things like that, but it
works quite nicely as a starting point.

The keyboard shortcut is Logo+Tab. :^)

57fe316e01 Detect the "Logo" (Windows/Apple/whatever) key and use it for window resize. 
This will be comfortable enough while I'm still developing with emulators.
QEMU keeps eating my "Alt" key presses and it's making things difficult.

159fa99539 Kernel: No need to check is_superuser() after may_execute(). 
Since may_execute() incorporates a superuser check. :^)

5e40aa4f1a LibGUI: Move shortcut actions from GEventLoop to GApplications. 
I'm gonna want to have nested event loops sooner or later, so let's not
pollute GEventLoop with things that are meant to work globally.

This patch also changes key events to pass around their modifiers as a
bitfield all the way around the system instead of breaking them up.

d94abc4f81 FileManager+LibGUI: Add a simple location textbox. 
The widget layout here is a bit off and needs work.

63cdc3d2d5 LibGUI: Support GTableView navigation with Page Up and Page Down. 
Also base the vertical scrollbar's gutter range on the visible content rect,
making it very similar to a Page Up/Down. Maybe they should be exactly the
same, I don't know.
 2019-03-02 23:58:45 +01:00

c350cf7b95 Kernel: Keyboard should detect the Page Up and Page Down keys. 2019-03-02 23:58:09 +01:00
Andreas Kling
596a5ce5a4 LibGUI+WindowServer: Add app-global keyboard shortcuts. 
This patch adds a GShortcut class. Each GAction can have a GShortcut which
will cause the event loop to listen for that key combination app-globally
and activate the event in case it's pressed.

The shortcut will also be displayed when the action is added to a menu.

Use this to hook up Alt+Up with the "open parent directory" action in the
FileManager app. :^)

5c0fca0a95 FileManager: Make the "open parent directory" action actually open ".." 2019-03-02 09:16:57 +01:00
Andreas Kling
e11c7a5df5 FileManager: Add "up to parent directory" action to toolbar. 
It's not actually hooked up to anything yet, I just wanted to add
something more to the toolbar. :^)

0c8242dd71 FileManager: Show user/group names instead of UID/GID if available. 2019-03-02 02:05:49 +01:00

2c5a378ccc Kernel+Userland: Add symlink() syscall and add "-s" flag to /bin/ln. 
It's now possible to create symbolic links! :^)

This exposed an issue in Ext2FS where we'd write uninitialized data past
the end of an inode's content. Fix this by zeroing out the tail end of
the last block in a file.

Andreas Kling
f75eb9af16 Kernel: Support chdir() to a directory that's executable but not readable. 
Also the superuser should be allowed to resolve any possible path without
getting tripped up by EACCES.

4f9b6a88a6 WindowServer: Use SA_NOCLDWAIT. 2019-03-01 16:16:38 +01:00
Andreas Kling
274b0260f7 Kernel: Don't send SIGCHLD to parent process if he has SA_NOCLDWAIT set. 
Just transfer ownership of the dead process to the colonel and let the
scheduler reap it on next iteration.

ac8fb5da4c FileManager: Port to GTableModel/GTableView. 
Replace the custom DirectoryView widget with a GTableView subclass.
This was pleasantly straightforward and it's so cool seeing the huge
increase in app quality from GTableView. :^)
 2019-03-01 13:55:48 +01:00

b5dcad932e LibGUI: Allow basic keyboard navigation in GTableView. 
Pressing Enter will now "activate" the selected index, meaning that
the model gets a call to activate(GModelIndex).
 2019-03-01 13:48:08 +01:00
Andreas Kling
e1d0a3f226 LibGUI: Let GTableModel handle the selection instead of doing it virtually. 
It's silly to force every subclass models to deal with selection.
 2019-03-01 13:03:13 +01:00
Andreas Kling
9c21874d33 LibGUI: GTableView scrolling ranges should be based on the available area. 
We have to subtract the headers and scrollbars to get the correct behavior.

6c2089c59d Put miscellaneous debug spam behind #ifdefs. 2019-03-01 10:51:58 +01:00
Andreas Kling
1b16a29044 Kernel+Userland: Implement fchmod() syscall and use it to improve /bin/cp. 
/bin/cp will now copy the permission bits from source to destination. :^)

b5e5f26a82 Base: Add Csilla Bold 7x10 variant. 
It's nice to have a thin and a bold variant to complement each other.
 2019-03-01 02:50:50 +01:00
Andreas Kling
0776c51bf5 Base: Import a new font, Csilla Thin (7x10). 
I wanted to do a bitmap font with an odd number of columns for a while
and I finally got around to it. This really looks rather nice, so I'm
making it the default system font for now. :^)
