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
  • event: what to call.
  • title: for use in ui.
  • section: under which menu to display (currently: device, filemanager, rolling, paging) 
    and optionally
  • min/max: for number
  • default
