Qt serial com

That was the constructor. There is destructor as well but it is unchanged from the template provided when creating the project. The updateSerialPorts function updates the list of serial ports by asking for the availablePorts.

The combo box is cleared to then be refilled with the list of ports. In this case what we provide for second argument is another string, so this is fine as a QVariant it seems. However, when we access the data field of the combo box, we must convert it from a QVariant to a string before use.

The combo box contents is accessed when the connect button is pressed. The selected item of the combo box is then read out. We only need to read out the data field from the combo box. The data is not actually displayed in the combo box, only the name is.

When we added items to the combo box we put the name of the port as the first or text argument to addItem which is what is displayed in the list.

The data from the combo box iten is converted from QVariant to string using toString. If the program is already connected to a serial port when the user clicks connect, the connection is closed. Now one idea could be to add more GUI elements where the user can fill in the parameters. If that had been the case, we could load the information from those GUI elements at this time and use them to set up the connection.
