[SOLVED] How do I print processor temperature in qml file as text?

Epidemic

Hi everyone. I tried to make an application on Raspberry Pi, I want to print the CPU temperature under the settings menu, but I do not know how to do it. Please help...

The following command shows the temperature; "/opt/vc/bin/vcgencmd measure_temp"

Text {
    id: text_temperature
    visible: true
    text: "48°C" 	//CPU temperature here.
    font.pixelSize: 21
    font.family: steelfish.name
    color: "#ffffff"
    smooth: true
    x: 75
    y: 20
}

I think you'll need to use QProcess in C++ to run the external command. Then store the result in a property, and you can reference the property directly from QML.

I fixed the problem, and now I'm trying to repeat the data at regular intervals.
Thanks.

int main(int argc, char* argv[])
{
QGuiApplication app(argc,argv);
QQuickView view;
view.setResizeMode(QQuickView::SizeRootObjectToView);

QObject *parent = 0;
QString program = "/opt/vc/bin/vcgencmd";
QStringList arguments;
arguments << "measure_temp";

QProcess *myProcess = new QProcess(parent);
myProcess->start(program, arguments);
myProcess->waitForFinished(1000);

QString result = myProcess->readAllStandardOutput();
QString subString = result.mid(5,2);
subString.append("°C");

view.rootContext()->setContextProperty("currentCpuTemp", subString);
view.setSource(QUrl("qrc:/main.qml"));
view.resize(848, 480);
view.show();

return app.exec();

}

You can move most of that into QML by using this approach:

YES bro, you are the king! That's EXACTLY what I want! :)

I'm sorry for the late answer.
