QextSerialPort WaitForReadyRead()

[kingslee]

It wont work as they did not implement it .

Check the win_qextserialport.h line nr. 107

virtual bool waitForReadyRead(int msecs); ///< @todo implement.

I wanna give it a shot .. but at the moment I dont have time to do it.

I used the wysota's way of using the Qtimer method.

Hi,

I don't want "waitForReadyRead", I want to connect "readyRead" SIGNAL and as I can see it is implemented on Windows using a QThread and Windows API functions.
I just want to know if "readyRead" SIGNAL works because now I have a polling Thread that increases CPU load.

Thanks,

You don't need a separate thread. You can check the port in the main thread. Timers are a bit heavy, so it might be better to use timerEvent() if you experience efficiency problems.

It is possible to do only by polling based on timer and check if data available.
Or you can make reasonable SIGNAL api yourself to hide polling

Hi,

I know that I can use a Timer but I want to know if using QextSerialPort 1.2 Alpha, the signal "readyRead" works !!!

If it works I don't need to use a Timer or a Thread, because it will call the properly SLOT when data arrives.

So, anyone have tested it?

Thanks,

I didn't manage to get it to work properly... Maybe that's why it's alpha
