This makes window modality a bit more discoverable by indicating to the
user that the modal window must be closed before mouse interaction is
possible in the clicked window.
When calling set_checked(true) on an exclusive button, we will now
transfer focus to the newly checked button if one of its now-unchecked
siblings had focus before.
This makes windows that place initial focus somewhere in a group of
radio buttons look nicer when they show up, since focus will be on
whichever radio button was pre-checked, which may not be the first one
in the group.
Making an AbstractButton exclusive means that we enforce that only one
of the exclusive buttons within the same parent widget can be checked
at a time.
RadioButton was doing exactly the same thing, except in a custom way.
So just remove the custom code and make it exclusive. :^)
Old font functionality has been moved into BitmapFont
and an abstract Font interface has been introduced to
faciliate further development of TTF font integration.
The infinite loop here doesn't really work at all for an application
process that expects to be able to exit. Check against
Core::EventLoop::current() to see if it's time to
exit, and return 0 from the thread function if so.
The thread will be joined in its destructor, which doesn't assert
anymore now that Thread is a jthread.
WavWriter::finalize didn't check that m_file was actually valid before
trying to seek and close it. The file is only set by set_file, so it's
not an invariant. Just add a null guard to finalize().
Because pthread_create will always call pthread_exit internally before
exiting the thread function, we can remove the odd requirement that the
user's thread function must call Thread::quit internally.
Make Thread::join clear m_tid on success, and print to stderr on
failure. Call join from ~Thread(). Now if you write an infinite loop in
your thread in an application and don't have an exit condition, you will
block in the thread's destructor forever. Time for stop_token? :)
Just constructing one of these guys on the stack willy nilly will leak
the first reference to them. There might be other C_OBJECTs that have
public constructors, seems like a good place for some static analysis
checks :).
Force users to call the construct() method for it.
Compared to version 10 this fixes a bunch of formatting issues, mostly
around structs/classes with attributes like [[gnu::packed]], and
incorrect insertion of spaces in parameter types ("T &"/"T &&").
I also removed a bunch of // clang-format off/on and FIXME comments that
are no longer relevant - on the other hand it tried to destroy a couple of
neatly formatted comments, so I had to add some as well.
When a new modal window is created, we still want to forward the
WindowDeactivated event to its parent window, despite it being blocked
by the newly created modal (which causes WindowServer's Window::event()
to ignore all incoming events from WindowManager for that window).
This fixes the "terminal doesn't stop blinking when blocked by modal
window" bug.
We don't want to trigger an actual selection change until either
confirming the new selection by keyboard or clicking on it.
Dismissing the dropdown should have no effect on the current
selection.

BlockCondition::unblock should return true if it unblocked at
least one thread, not if iterating the blockers had been stopped.
This is a regression introduced by 49a76164c.
Fixes#4670
This assertion cannot be safely/reliably made in the
~SharedInodeVMObject destructor. The problem is that
Inode::is_shared_vmobject holds a weak reference to the instance
that is being destroyed (ref count 0). Checking the pointer using
WeakPtr::unsafe_ptr will produce nullptr depending on timing in
this case, and WeakPtr::safe_ref will reliably produce a nullptr
as soon as the reference count drops to 0. The only case where
this assertion could succeed is when WeakPtr::unsafe_ptr returned
the pointer because it won the race against revoking it. And
because WeakPtr::safe_ref will always return a nullptr, we cannot
reliably assert this from the ~SharedInodeVMObject destructor.
Fixes#4621
We previously had a cached bold variant font in Gfx::Font that was very
haphazardly located by filename pattern. This patches replaces that
mechanism with a proper Gfx::FontDatabase lookup for the same font but
with bold weight (700).
If a heap expansion is triggered by allocating from e.g. the
RangeAllocator, which may be holding a spin lock, we cannot
immediately allocate another block of backup memory, which could
require the same locks to be acquired. So, defer allocating the
backup memory
Fixes#4675
Loader.so is an actual executable, as well as the interpreter for dynamic
libraries. Currently launching Loader.so as a standalone executable results
in an obsucre crash as it tries to load itself over itself.
Now we at least print a helpful message saying that you're doing the wrong
thing and exit gracefully. In future we may wish to allow users to specify
additional options to learn more about what's going on during dynamic
linking, such as ld-linux.so.2 on Linux.
Since RefPtr<T> decrements the ref counter to 0 and after that starts
destructing the object, there is a window where the ref count is 0
and the weak references have not been revoked.
Also change WeakLink to be able to obtain a strong reference
concurrently and block revoking instead, which should happen a lot
less often.
Fixes a problem observed in #4621
