<description summary="advertise available modes for the output">
|
|
The mode event describes an available mode for the output.
|
|
The event is sent when binding to the output object and there
|
|
will always be one mode, the current mode. The event is sent
|
|
again if an output changes mode, for the mode that is now
|
|
current. In other words, the current mode is always the last
|
|
mode that was received with the current flag set.
