Detailed Description

This section explains how to handle events generated by the client instance.

When events occur in the client instance, like e.g. if a new user joins a channel, the client instance queues a TTMessage which the user application must retrieve using TT_GetMessage(). The message queue for events is limited to 1 MB. If the queue grows above the maximum size then event handling is suspended and will not be resumed until the queue size is again below the maximum size. The event INTERR_TTMESSAGE_QUEUE_OVERFLOW will be posted to the message queue if an overflow has taken place.

If TT_InitTeamTalk is used with a HWND then the events are sent to the user application with WinAPI's PostMessage(...) function and is retrieved through GetMessage(...).

Note that when an event occurs the TeamTalk client instance doesn't wait for the user application to process the event. So if e.g. a user sends a text-message and immediately after disconnects from the server, then the User, who sent the message, cannot be retrieved using TT_GetUser() since the user is no longer available when the user application starts processing the new text-message event. This is, of course, annoying when designing the user application, but the reason for this design choice it that the client instance is a realtime component which cannot wait for the UI to process data, since audio playback and recording would then be halted.

The section Client Programming Guide gives a good idea of how events are processed in a user application.

Typedef Documentation

CLIENTEVENT_HOTKEY_TEST	A button was pressed or released on the user's keyboard or mouse. When TT_HotKey_InstallTestHook is called a hook is installed in Windows which intercepts all keyboard and mouse presses. Every time a key or mouse is pressed or released this event is posted. Use TT_HotKey_GetKeyString to get a key description of the pressed key. Attribute values in TTMessage: TTMessage.nSource The virtual key code. Look here for a list of virtual key codes: http://msdn.microsoft.com/en-us/library/ms645540(VS.85).aspx TTMessage.ttType __TTBOOL TTMessage.bActive Placed in union of TTMessage. TRUE when key is down and FALSE when released. See also TT_HotKey_InstallTestHook
CLIENTEVENT_FILETRANSFER	A file transfer is processing. Use TT_GetFileTransferInfo to get information about the file transfer. Ensure to check if the file transfer is completed, because the file transfer instance will be removed from the client instance when the user application reads the FileTransfer object and it has completed the transfer. Attribute values in TTMessage: TTMessage.nSource 0 TTMessage.ttType __FILETRANSFER TTMessage.filetransfer Placed in union of TTMessage. Properties and status information about the file transfer. See also TT_GetFileTransferInfo To retrieve FileTransfer.

CLIENTEVENT_AUDIOINPUT	Progress is audio being injected as STREAMTYPE_VOICE. nStreamID of AudioInputProgress is the stream ID provided in the AudioBlock when calling TT_InsertAudioBlock(). When uElapsedMSec and uQueueMSec of AudioInputProgress are zero then the stream ID (session) has ended. An audio input session has ended when an empty AudioBlock has been inserted using TT_InsertAudioBlock(). Attribute values in TTMessage: TTMessage.nSource Stream ID used for sending audio input. The stream ID will appear in AudioBlock's nStreamID on the receiving side. TTMessage.ttType __AUDIOINPUTPROGRESS TTMessage.audioinputprogress Placed in union of TTMessage. Tells how much audio remains in queue. The queue should be refilled as long as the audio input should remain active.
CLIENTEVENT_USER_FIRSTVOICESTREAMPACKET	The first voice packet of a new voice stream has been received. This time of this event may differ significantly from the start of the voice playout that is notified via CLIENTEVENT_USER_STATECHANGE due to jitter buffering. The time between CLIENTEVENT_USER_FIRSTVOICESTREAMPACKET and CLIENTEVENT_USER_STATECHANGE is the fixed jitter delay configuration plus the currently active adaptive jitter buffering in the nActiveAdaptiveDelayMSec member of the User struct Attribute values in TTMessage: TTMessage.nSource Stream ID.
