IconView now responds to the editing key (F2) if the view is editable.
It does feel a little bit weird to have content_rect() return the text
rect for an item, and not the whole item rect. This internal API could
probably be better.
With this commit, <AK/Format.h> has a more supportive role and isn't
used directly.
Essentially, there now is a public 'vformat' function ('v' for vector)
which takes already type erased parameters. The name is choosen to
indicate that this function behaves similar to C-style functions taking
a va_list equivalent.
The interface for frontend users are now 'String::formatted' and
'StringBuilder::appendff'.
Don't require clients to templatize modrm().read{8,16,32,64}() with
the ValueWithShadow type when we can figure it out automatically.
The main complication here is that ValueWithShadow is a UE concept
while the MemoryOrRegisterReference inlines exist at the lower LibX86
layer and so doesn't have direct access to those types. But that's
nothing we can't solve with some simple template trickery. :^)
This is useful for reading and writing doubles for #3329.
It is also useful for emulating 64-bit binaries.
MemoryOrRegisterReference assumes that 64-bit values are always
memory references since that's enough for fpu support. If we
ever want to emulate 64-bit binaries, that part will need minor
updating.
Fixes keyboard increment/decrement of SpinBox values.
After PR #2412 the TextBox class started not propagating arrow key
events to the parent widgets because it handles them itself now.
It also added two new events for these arrow keys, so use them instead
in SpinBox.
With this patch, we now enforce basic same-origin policy for this one
<iframe> attribute.
To make it easier to add more attributes like this, I've added an
extended IDL attribute ("[ReturnNullIfCrossOrigin]") that does exactly
what it sounds like. :^)
Getting ready for some extremely basic same-origin policy stuff,
this initial implementation simply checks that two origins have
identical protocol, host and port.
Empty string is extremely common and we can avoid a lot of heap churn
by simply caching one in the VM. Primitive strings are immutable anyway
so there is no observable behavior change outside of fewer collections.
To make it a little clearer what this is for. (This is an RAII helper
class for adding and removing an Interpreter to a VM's list of the
currently active (executing code) Interpreters.)
Since TCP sequence numbers are randomly choosen 32-bit numbers, it often
happend that the most significant bit was set. The cast to a 32-bit
signed integer then made the number negative.
Thus TCP sequence were shown negative in the SystemMonitor every so
often.
Taking a big step towards a world of multiple global object, this patch
adds a new JS::VM object that houses the JS::Heap.
This means that the Heap moves out of Interpreter, and the same Heap
can now be used by multiple Interpreters, and can also outlive them.
The VM keeps a stack of Interpreter pointers. We push/pop on this
stack when entering/exiting execution with a given Interpreter.
This allows us to make this change without disturbing too much of
the existing code.
There is still a 1-to-1 relationship between Interpreter and the
global object. This will change in the future.
Ultimately, the goal here is to make Interpreter a transient object
that only needs to exist while you execute some code. Getting there
will take a lot more work though. :^)
Note that in LibWeb, the global JS::VM is called main_thread_vm(),
to distinguish it from future worker VM's.
This will be inherited by documents and workers, to provide a common
abstraction for script execution. (We don't have workers yet, but we
might as well make this little space for them now to simplify things
down the road.)
This one is a little weird. I don't know why it's okay for this
function to assume that there is a current scope on the scope stack
when it can be called during global object initialization etc.
For now, just make it say "we are in strict mode" when there is no
currently active scope.
