With this patch, CEvents no longer stop at the target object, but will
bubble up the ancestor chain as long as CEvent::is_accepted() is false.
To the set accepted flag, call CEvent::accept().
To clear the accepted flag, call CEvent::ignore().
Events start out in the accepted state, so if you want them to bubble
up, you have to call ignore() on them.
Using this mechanism, we now ignore non-tabbing keydown events in
GWidget, causing them to bubble up through the widget's ancestors. :^)
Long-term we should use reference counting for the CObject hierarchy.
Since we've already accumulated a fair amount of code, this is quite a
large task, so I'm breaking it into some steps.
So, ObjectPtr is a "smart" pointer for CObject-derived types.
It becomes null when moved from, and will destroy unparented CObjects
in its destructor.
The idea here is to convert the codebase over to ObjectPtr piece by
piece, and then when everything is moved and CObject itself refactored
for ref-counting, we can just replace ObjectPtr with RefPtr everywhere.
Made getsockopt() and setsockopt() virtual so we can handle them in the
various Socket subclasses. The subclasses map kinda nicely to "levels".
This will allow us to implement things like "traceroute", although..
I spent some time trying to do that, but then hit a wall when it turned
out that the user-mode networking in QEMU doesn't preserve TTL in the
ICMP packets passing through.
The delete action now actually deletes files (after asking the user for
confirmation, of course.) Deleting directories is not yet supported.
Fixes#541.
Booting without a wallpaper is significantly faster in QEMU when the
host machine is under load (e.g while recording the screen..)
Using a wallpaper is now optional. :^)
When we ask LibGUI to hit test, it may return a subwidget of a widget
composed of many smaller widgets. In those cases we need to locate the
appropriate corresponding VBWidget for the composite widget.
This patch makes it possible to put widgets inside one another. The way
you do this right now is by having a (single) widget selected when you
insert a new widget. The new widget then becomes a child of the
selected widget. (In the future we'll make it possible to drag widgets
into each other, and things like that.)
I've also changed the grabber coordinates to be window-relative instead
of parent-relative in order to simplify things for myself. Maybe that's
not the ideal design and we can revisit that.
Normally if a GWidget has the is_greedy_for_hits() flag set, all hit
tests will hit the widget itself instead of its descendants.
Sometimes it may be desirable to override this behavior, and so this
flag now allows you to do that.
You can now copy into the system clipboard like this:
$ copy hello friends
or like this:
$ copy < ReadMe.md
or like this:
$ copy --type png < /res/wallpapers/sunset-retro.png
And paste just with
$ paste
or to view the copied type:
$ paste --print-type
We now no longer hardcode the sigreturn syscall in
the signal trampoline. Because of the way inline asm inputs
work, I've had to enclose the trampoline in the function
signal_trampoline_dummy.
Fix a crash when opening a folder, and another one when trying to open
a newly created folder.
It was not safe to modify a GModelSelection while it's being iterated over.
Fixes#536.
Sometimes you want to move the Rect by its right or bottom edge without
resizing the rect in the process. There are probably better names for
this but nothing comes to mind at the moment.
You can now call GWindow::set_fullscreen(bool) and it will go in or out
of fullscreen mode.
WindowServer will also remember the previous window rect when switching
to fullscreen, and restore it when switching back. :^)
This is a freelist allocator with static size classes that works as a
complement to the generic kmalloc(). It's a lot faster than kmalloc()
since allocation just means popping from the freelist.
It's also significantly more compact when there are a lot of objects
smaller than the minimum kmalloc chunk size (32 bytes.)
This patch enables it for the Region and PhysicalPage classes.
In the PhysicalPage (8 bytes) case, it's a huge improvement since we
no longer waste 75% of the storage allocated.
There are also a number of ways this can be improved, so let's keep
working on it going forward.
When the user has scrolled up and begins typing, the scrollbar will
automatically return them to the current cursor position so that they
can see what they're typing.
The program will now automatically select the user's currently
chosen resolution when it is loaded up, however it is not
"visually selected" in the `GListView`
Moved the `resolution_list` list to be on the top to keep it consistent
with the wallpaper tab.
