The Qemu I8042 controller does not send one IRQ per event, it sends
over four since it will not stop trying to emulate the PS/2 mouse.
If the VMWare backdoor is active, a fake I8042 mouse event will be sent
that we can then use to check if there are VMWare mouse events present.
However, we were only processing one mouse event at a time, even though
multiple events could have been queued up. Luckily this does not often
lead to issues, since after the first IRQ we would still get three
additional interrupts that would then empty the queue.
This change makes sure we always empty the event queue immediately,
instead of waiting on the next interrupt to happen. Functionally this
changes nothing - it could merely improve latency by not waiting for
new interrupts to come in.
Coincidently, this brings our implementation closer to how Linux deals
with the VMMouse.
Previously, trailing whitespaces were not removed from values in
config files. This could cause errors with poorly formatted files.
This commit fixes this by trimming whitespaces from values in
ConfigFile::reparse().
This makes the cursor update properly if it was above the window
switcher while it was visible, and something underneath it wants to use
something other than the default arrow cursor.
...to reevaluate_hover_state_for_window(). This name is not super great
either, but at least it doesn't sound like the window is necessarily
currently being hovered.
This makes teardown faster since we don't have to wait for responses to
each destroy_window request. It also avoids doing IPC during teardown,
which is a general source of problems.
This reverts commit 4131b35851.
We're swallowing way too many mouse events from QEMU with this code
enabled. Something is not right, so let's revert it for now.
Implement, and use internally, content_margins() from Widget.
Since AbstractScrollableWidget already has a method called content_size,
the convenience method, with the same name, in Widget has to be
explicitly called.
Even though they are called content_margins,
they are actually only ever used to determine where
a Widget is supposed to be grabbable.
So all methods and members are renamed accordingly.
We achieve this by simply setting the intrinsic size to the size needed
to render the replacement text.
This fixes a long-standing issue where non-loaded images would default
to the goofy-looking 300x150 fallback size for replaced elements.
In 2e6bb987a3 the "did_construct" API in
Core::Object was removed, since it had only one user. For a replacement,
the Window would manually call the frame's "frame_was_constructed"
method. However, WindowServer::Window has two constructors, and only one
of them called this method. This caused windows to spawn without
buttons and various other breakage that spawned from this.
