Refactor, follow up of 90b7944. Add a modification step to the "special"
layouts: numpad, greekmath, pin entry.
Remove the apply_key0 function, which is not expressive enough.
Add an enum instead of yet an other "switch_" function.
Send key events for the left or right arrow as the finger slides on the
space bar.
Can be used to select text by holding shift. Works under Termux.
Events are sent linearly as the finger travels. The distance between
each events is defined from the swiping distance divided by 4.
'slider="true"' can be set on a key that have 'edgekeys="true"'.
'key2' and 'key3' represent the right and left keys.
It allowed to modulate the repeat speed of some keys (arrow, backspace,
delete) by move the finger farther or closer to the key.
In practice, this wasn't pratical and doesn't seem popular. It is
removed in favor of a better mechanism for moving the cursor.
Stay on the secondary layout after a config refresh or onStartInputView.
The information is kept until the keyboard is restarted.
Additionally, move tweaking the secondary layout to the Config class now
that physical equality is not needed.
Values like 'characterSize' and 'horizontalMargin' can't be fed back into the default value because they are not of the same unit.
To avoid this happening again, change the way the default value is defined for every options.
The 'key_height' dimension was no longer used.
The most requested keys are undo and redo. Unfortunatly redo doesn't
work reliably.
The other context menu actions like share, assist and autofill are added
even thought they are rarely useful or implemented.
* Add option for keyboard opacity (transparency). Keyboard background, keys and pressed keys can be adjusted separately.
* Make the borders transparent as well
* Moved setAlphas outside drawKeyFrame to top of onDraw method
setInputView() was not called when the view was re-created through
refresh_config(). Also, the refresh_config() function was not able to
properly set the current layout.
Now keep the default layout (_localeTextLayout) and the current non-text
layout (if any, _currentSpecialLayout) separately to be able to refresh
them later.
setInputView() is called everytime the view is created instead of by
onStartInputView() specifically.
The setting activity now save the preferences to the protected storage
in onStop() instead of listening for onSharedPreferenceChanged.
The callback might not be called if the "default" shared preferences is
different from the shared preferences actually used. This is unexpected
but seems to happen half of the time on Android 12.
Since f1ce6ab, this callback is critical to update the keyboard.
Restarting the application can no longer solve these issues.
Some users reported that 25% of the screen height is too high on their
screen. This doesn't seem to be a good way to define the height but
until it is improved, allow smaller values.
Add an option for specifying an XML layout description as a string.
The option is a bit rough at the moment:
- No documentation, users have to be aware of the keyboard's code to use
this option.
- No error are shown, the layout will fallback to qwerty on error.
