This adds support for the equalize_splits feature that's already
implemented for macOS.
It's essentially a port of the Swift implementation, using the same
weights-mechanism to equalize split sizes.
Fixes#1014
There were a couple overlapping issues here:
1. To determine the "unshifted" key, we were using `keyval_to_lower`.
This only works if the key is uppercase and not all layouts are
uppercase for the unshifted value.
2. If we couldn't case the unicode value of a key or unshifted key to
ASCII, we'd say the key was the same as the physical key. This is
incorrect because the physical key is always the layout of the
physical keyboard so for example with the Turkish layout on a US
keyboard, you'd get US letters when a key may only correspond to
non-US letters.
To fix the first issue, we are using map_keycode to map the hardware
keycode to all possible keyvals from it. We then use the currently
active layout to find the unshifted value.
To fix the scond issue, we no longer fallback to the physical key if
there was IM text or non-ASCII unicode values for the key.
I tested Turkish with #1014 and I tested Dvorak to make sure those
basics still work.
Fixes#965
When processing keybindings that closed the surface (`close_surface`,
`close_window`), the surface and associated runtime structures would be
freed so we could segfault.
This PR introduces a new enum result for input events (only key for now)
that returns whether an event resulted in a close. In this case, callers
can properly return immediately and avoid writing to deallocated memory.
This adds support for resizing splits via keybinds to the GTK runtime.
Code is straightforward. I couldn't see a way to do it without keeping
track of the orientation of the splits, but I think that's fine.
Fixes#933
On startup, we'd set the cursor to "text" but we wouldn't store that as
our cursor so when the mouse was unhidden, we'd go back to "default".
This PR changes it so that on surface startup we set and store the
"text" cursor so as the cursor hides/shows it reverts to the proper
value.
Fixes#882
This hooks up all the GTK.IMContext things properly so that we support
switching input methods, popups, etc. This should improve our support
for asian languages, emoji input, etc.
