Member Function Documentation

void DirKeeper::HandleMessage ( Message * pcMessage ) [virtual]

Reimplemented from os::Handler.

bool DirKeeper::Idle ( ) [virtual]

Hook called each time the message queue is drained. Description: Normally the looper thread is blocked on the internal message queue waiting for messages. When one or more messages arrive it will wake up and process the messages. When all messages is processed it will first call Idle() and then go back looking for more messages. If Idle() returned false the thread will block until the next message arrive and if Idle() returned true it will just look for new messages without blocking and call Idle() again (after processing new messages if any). Note: The looper will not be able to process new messages until Idle() returns so it is very important to not do anything lengthy if the looper is part of for example an os::Window since that will make the application feel "unresponcive" to the user. Returns: The Idle() function should return true if it want to be called again imediatly after the looper has polled for new messages, or false if it don't want to be called until at least one more message has been processed.
