Description [src] 

abstract class Valent.DevicePlugin : Valent.Extension
  implements Gio.ActionGroup, Gio.ActionMap {
  /* No available fields */
}

An abstract base class for device plugins.

ValentDevicePlugin is a base class for plugins that operate in the scope of a single device. This usually means communicating with other devices, however plugins aren’t required to be packet based.

Plugin Requirements

Device plugins essentially have two sets of dependent conditions for being enabled. Plugins become available (i.e. can be enabled) when any of the following are true:

  • any of the device’s outgoing capabilities match any of the plugin’s incoming capabilities
  • any of the device’s incoming capabilities match any of the plugin’s outgoing capabilities
  • the plugin doesn’t list any capabilities (eg. a non-packet based plugin)

When a plugin becomes available it may be enabled, disabled and configured.

Plugin Actions

ValentDevicePlugin implements the GActionGroup and GActionMap interfaces, providing a simple way for plugins to expose functions and states. Each GAction added to the action map will be included in the device action group with the plugin’s module name as a prefix (eg. share.uri).

If the ValentDeviceManager is exported on D-Bus, the actions will be exported along with the ValentDevice.

Implementation Notes

Implementations that define X-DevicePluginIncoming in the .plugin file must override Valent.DevicePluginClass.handle_packet to handle incoming packets. Implementations that depend on the device state, especially those that define X-DevicePluginOutgoing in the .plugin file, should override Valent.DevicePluginClass.update_state.

.plugin File

Implementations may define the following extra fields in the .plugin file:

  • X-DevicePluginIncoming

    A list of packet types (eg. kdeconnect.ping) separated by semi-colons indicating the packets that the plugin can handle.

  • X-DevicePluginOutgoing

    A list of packet types (eg. kdeconnect.share.request) separated by semi-colons indicating the packets that the plugin may send.

  • X-DevicePluginSettings

    A GSettings schema ID for the plugin’s settings. See valent_context_get_plugin_settings() for more information.
