It's pretty comfy having arguments in registers in the kernel for now though.
|
|
Let GButton have an optional icon (GraphicsBitmap) that gets rendered in the
middle of the button if present.
Also add GraphicsBitmap::load_from_file() which allows mmap'ed RGBA32 files.
I wrote a little program to take "raw" files from GIMP and swizzle them into
the correct byte order.
|
|
For now, the WindowServer process will run with high priority,
while the Finalizer process will run with low priority.
Everyone else gets to be "normal".
At the moment, priority simply determines the size of your time slices.
|
|
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.

While working on the ELF loader I was trying to keep binaries as simple as
possible so I could understand them easily. Now that the ELF loader is mature
and working fine, we can move closer towards ld defaults.

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.

We can't not have a desktop clock app. :^)
|
|
This seems like an extremely relevant metric to track.
|
|
LizaRegular is quickly becoming my favorite bitmap font. It's so pretty :^)
|
|
Also use an enum for the rather-confusing return value in dispatch_signal().
I will go through the rest of the signals and set them up with the
appropriate default dispositions at some other point.

This feels nicely reminiscent of the gap in time between Win3.11 and Win95,
one of my favorite eras in UI look-and-feel.
|
|
It automagically computes %CPU usage based on the number of times a process
has been scheduled between samples. The colonel task is used as idle timer.
This is pretty cool. :^)
|
|
Also change /bin/cat to open /dev/stdin if no arguments are provided.
|
|
|
|
Looks like that's all we needed, and bc now runs. :^)

Editing fonts by editing text files is really slow and boring.
A simple font editor seems like a good way to take LibGUI for a spin.
|

|
Added the -i option to ls which turns on inode number display.
|
|
|
|
This is driven by mousedown events right now, since there are no timers.
|
|
FileDescriptor will now keep a pointer to the original inode even after
opening it resolves to a character device.
Fixed up /bin/ls to display major and minor device numbers instead of size
for device files.
|

You can now open as many PTY pairs as you like. Well, it's actually capped
at 8 for now, but it's just a constant and trivial to change.
Unregistering a PTY pair is untested because I didn't want to start
mucking with that in Terminal right now.
|
|
Only raw octal modes are supported right now.
This patch also changes mode_t from 32-bit to 16-bit to match the on-disk
type used by Ext2FS.
I also ran into EPERM being errno=0 which was confusing, so I inserted an
ESUCCESS in its place.
|
|
Also add a /bin/dmesg program for convenience.
|
|
It's really only supported in Ext2FS since SynthFS doesn't really want you
mucking around with its files. This is pretty neat though :^)
I ran into some trouble with HashMap while working on this but opted to work
around it and leave that for a separate investigation.

- Make it track the mouse cursor just like GButton does so that changes only
get committed if the mouseup event happens while inside the widget rect.
- Draw a focus rect around the box when appropriate.
- When focused, support toggling the checked state with the space bar.

Instead of clients painting whenever they feel like it, we now ask that they
paint in response to a paint message.
After finishing painting, clients notify the WindowServer about the rect(s)
they painted into and then flush eventually happens, etc.
This stuff leaves us with a lot of badly named things. Need to fix that.

It's weird that I didn't do this sooner. I don't know how many tims
I've had to retype a misspelled command. :^)
|
|
Use this in the /bin/sh prompt to keep the window title in sync with the
shell's working directory. :^)
|
|
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.
|

This patch adds most of the plumbing for working file deletion in Ext2FS.
Directory entries are removed and inode link counts updated.
We don't yet update the inode or block bitmaps, I will do that separately.
