handling return parameter for a cpp method /slot in QML

[Prasad_Socionext]

onClicked:{

           data = cpp_cmd.cmd_do(cmdline_txt_id.text);
            console.log(data);
        }

I have a slot called cpp_cmd.cmd_do() which is called when a button is pressed.
that cpp slot has a return paramter a string. (which contains json data) .

return type of data is QString.

i am not able to display it and it gives an error. how would one solve this.

I need to futher process data or rather send it to another cpp function for further processing.

Hi,

What exact error do you get ?

Usually slots don't have return values. Q_INVOKABLE is used for that kind of method.
