Updating elements in model of Combobox from c++
-
I have created a combobox in which I want to show all the serial ports from my computer.
I update them through a button I have which calls a slot to fetch all ports in a QStringList (I just keep the port name).
I want to show that list of ports in my combobox so I did something like:
Q_PROPERTY(QStringList comPortList READ getCOMPorts NOTIFY comPortsChanged)My combobox:
ComboBox { id: comport_box currentIndex: 0 textRole: "text" model:_managerInstance.comPortList width: 200 }It shows an updated list. If there are 5 ports, combobox has 5 rows, 4 ports, 4 rows... But all rows are empty. I cannot get the text on each row. I am pretty sure the QStringList has the text because I print with qDebug before passing it.
Do I need to add something else to that combobox to update the text in each row?

Since your model is a
QStringList, it doesn't have roles.
Remove thetextRole: "text"line and you should be fine.
