Module dispatcher
This module is responsible for dispatching events.
To add a new action an entry must be added to settingsList & dispatcher_menu_order
This can also be done at runtime via registerAction().
settingsList contains the list of dispatchable settings.
Each setting contains:
- category: one of:
* none: a direct event call * arg: a event that expects a gesture object or an argument * absolutenumber: event that sets a number * incrementalnumber: event that increments a number & accepts a gesture object * string: event with a list of arguments to chose from * configurable: like string but instead of an event it updates the configurable (used by kopt)
- event: what to call.
- title: for use in ui.
- section: under which menu to display (currently: general, device, screen, filemanager, reader, rolling, paging)
and optionally - min/max: for number
- step: for number
- default
- args: allowed values for string.
- toggle: display name for args
- separator: put a separator after in the menu list
- configurable: can be parsed from cre/kopt and used to set
document.configurable. Should not be set manually
