* [toggleswitch] Add support for key navigation to this widget
Add the onFocus an onUnfocus event handler
add a new function that just circle the switch if not touch event is
detected
* Add key navigation to the readermenu
The shortcut is still Alt-gr on sdl, to be defined on Kindle
* Remove the old method of handling the Press key.
Now the event is handled by the main widget who implement focusmanager
and then dispatched to the currently focused item.
Modify the fine font tuning only for non touch-devices
See : https://github.com/koreader/koreader/pull/3785#issuecomment-375306466
Just under the existing "Embedded Styles". Support for this
was already there in crengine, and interfacing is similar to
what is done with Embedded Styles.
* Add a basic Japanese keyboard layout
Allow for entring Japanese text into text boxes. Only supports kana
and latin letters due to limitations of current VirtualKeyboard
implementation (complex text input with conversion is not possible).
* Allow keyboard layouts to declare custom modifiers
Refactor modifier key setup code and existing keyboard layouts so
that each layout can declare custom modifier key labels. This
allows for greater extensibility and for future keyboard layouts.
A new feature 'read from right to left' is added, which is more fit for
Traditional Chinese and Japanese books. Once the feature is enabled:
1. The gesture region of TapForward and area will be flipped
horizonally;
2. The action for swiping to west and to east will be exchanged.
This is a major overhaul of the hardware abstraction layer.
A few notes:
General platform distinction happens in
frontend/device.lua
which will delegate everything else to
frontend/device/<platform_name>/device.lua
which should extend
frontend/device/generic/device.lua
Screen handling is implemented in
frontend/device/screen.lua
which includes the *functionality* to support device specifics.
Actually setting up the device specific functionality, however,
is done in the device specific setup code in the relevant
device.lua file.
The same goes for input handling.
