Overview ¶
displaycloud provides basic functionality to interact with the DisplayCloud "middleware".
The displaycloud package is used by mrclean to interact with the DislpayCloud middleware. It provides the basic functionalities to marshal and unmarshal the JSONRPC messages to be sent via websocket. It connects to DisplayCloud and do handle all the calls to adding, soerting and grouping new visuals. There is a stub for the handling of events coming from other sources, e.g. if someone move a visual from another client we got a event but we ignore it so far.
