Description [src] 

abstract class Valent.InputAdapter : Valent.Extension {
  parent_instance: ValentExtension
}

An abstract base class for virtual input devices.

ValentInputAdapter is a base class for plugins that provide an interface to the pointer and keyboard. This usually means simulating pointer and keyboard events on the host system.

.plugin File

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

  • X-InputAdapterPriority

    An integer indicating the adapter priority. The implementation with the lowest value will be used as the primary adapter.
