how to make the slot runs in receive thread?
Hi all,
I have many TCPSocketThread to connect with users, and DataHandlerThread to deal with the data received from TCPSocketThread.
There might be a lot of TCP connections, and each data transfer will affect database. So I implemented a Database ThreadPool to manage DataHandlerThreads.
Look at this connect.
- QObject::connect(pThread, SIGNAL(execFinished(TWorkThread*)), this, SLOT(dataDealFinishedEvent(TWorkThread*)));
pThread is DataHandlerThread. When this thread finished it’s work, it should tell the socketThread it finished(execFinished), then this TCPSocketThread should return the DataHandlerThread to ThreadPool.
As now, I can make the readyRead->dataReceivedEvent() work well, the TCPSocketThread::dataReceivedEvent now works in TCPSocketThread.
In TCPSocketThread::dataReceivedEvent, I make that connect, anyway I debug, the triggerred thread are main thread or DataHandlerThread.(With Qt::DirectConnection, Qt::QueriedConnection)
Are there any who can tell me how I can make the slot dataDealFinishedEvent runs in TCPSocketThread??
Many thanks,
Kevin

is TCPSocketThread a subclas of QThread? If yes, the object itself belongs to the creating thread (typically the main thread), and the slot will be executed there. Have a look at peppes article about threads. [developer.qt.nokia.com]
