Use in QML:

    Component.onCompleted: {
      process.start("some-bin", ["some args"])
    }


    Text {
        id: output
        x: 0
        y: 0
        text: ""
    }


    Process {
        id: process
        //onReadyRead: {output.text += readAll();output.text += readAllStandardOutput();}
        onReadyReadStandardError: {output.text += readAllStandardError();}
        onFinished: {
            console.log("finished", exitCode)
            output.text += exitCode.toString()
            console.log(readAllStandardError());
        }
        onErrorOccurred: {
            console.log("error!");
            output.text += readAllStandardError()
        }
    }
