List serial ports in Qt application on windows and Mac

I am creating one Qt based application for windows and Mac OS X. I used Qextserial port to connect and communicate through serial port it works well.

But now I need to list existing serial ports in a system like "COM1" "COM2" etc.

How I can do this in Qt, is there any native C++ code available to list existing serial ports in a system that i can include in Qt application

Did you read the QextSerialPort documentation? There are only two classes and the bit about QextSerialEnumerator will be illuminating.

I didn't understand. Is there any function to get existing serial ports in a system

There is no function available to list existing serial ports in QExtserilport. They are simply hard coded the portnames

They are used like this
port = new QextSerialPort("COM1");

but i need to get this "COM1" from system

From the link posted by Chris:

QextSerialEnumerator enumerates ports currently available in the system.

QextSerialEnumerator::getPorts

Get list of ports.

return list of ports currently available in the system.

As they say in English: "You can lead a horse to water, but you can't make him drink."
