Output functions

Channel_ events

Channel_OnAppClose

Triggered when the Activity window is destroyed.

Technical: Called by a beforeunload handler in messenger.js.

Channel_OnDataError

Triggered if a window.external.Channel.SendData() were to fail on the local client.

The local client should handle the Error object in window.external.Error:

Type: long, Type of error thrown. Data: string, Data which failed to send.

Channel_OnDataReceived

Triggered after the remote client calls window.external.Channel.SendData().

The local client should handle the data given in window.external.Channel.Data as a string.

Channel_OnFileProgress

Unimplemented. Only fired if Activity has SendFile permission.

Triggered after data has been sent over the channel to the remote client regarding a file transfer.

Channel_OnFileReceived

Unimplemented. Only fired if Activity has SendFile permission.

Triggered after a file transfer to the local client is received.

Channel_OnIMReceived

Unimplemented. Only fired if Activity has ReceiveIM permission.

Triggered by retriving a chat message to the local client.

The local client should handle the data given in window.external.Channel.IM as a string.

If the Activity was to have the ReplaceIM permission, window.external.Channel.IM is writable, for which the modified value will be the message sent to the chat-box.

Channel_OnRemoteAppClosed

Triggered when the remote client's Activity window has been destroyed.

The local client should be expected to clean up and display a "remote client has left" message.

Channel_OnRemoteAppLoaded

Triggered when the remote client's Activity window has fired window.external.Channel.Initialize().

Channel_OnSendFileCancelled

Unimplemented. Only fired if Activity has SendFile permission.

Triggered when a file transfer is cancelled by either client.

Channel_OnTypeChanged

Triggered when the connection type changes.

The local client can see the new connection type by getting window.external.Channel.Type, which provides these values:

0: Direct connection, Switchboard connection exists, but the local client has a direct connection to the remote client.

1: Indirect connection, Clients can send data, but must go through Switchboard.

2: Disconnected, No connection to the remote client.
