Hiding mouse cursor, qt quick

Re: Hiding mouse cursor in QML

Tried both solutions given in this thread separately but they don't seem to do anything to the display, a pointer always shows up at the top left of the display. Other solutions attempted are creating a mouse area under the window and blanking that cursor, but I don't even have a mouse plugged in and will strictly use a touch screen.

Here is my main.qml:

import QtQuick
import QtQuick.Window 2.15
import QtQuick.Controls 2.0
import io.qt.backend 1.0

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
    HoverHandler {
        id: mouse
        cursorShape: Qt.BlankCursor
    }
}

and main.cpp

#include <QGuiApplication>

#include <QQmlApplicationEngine>


int main(int argc, char *argv[])
{
    if (qEnvironmentVariableIsEmpty("QTGLESSTREAM_DISPLAY")) {
        qputenv("QT_QPA_EGLFS_PHYSICAL_WIDTH", QByteArray("213"));
        qputenv("QT_QPA_EGLFS_PHYSICAL_HEIGHT", QByteArray("120"));

#if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)
        QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
#endif
    }
    QGuiApplication app(argc, argv);
    QGuiApplication::setOverrideCursor;

    QQmlApplicationEngine engine;
    const QUrl url(QStringLiteral("qrc:/main.qml"));
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
        &app, [url](QObject *obj, const QUrl &objUrl) {
            if (!obj && url == objUrl)
                QCoreApplication::exit(-1);
        }, Qt::QueuedConnection);
    engine.load(url);

    return app.exec();
}

for this second solution I get warning: statement has no effect [-Wunused-value]

using qt 6.5, ubuntu,

@hazbody21 QGuiApplication::setOverrideCursor is a function.

@GrecKo
Thank you for the clarification. Adding

QGuiApplication::setOverrideCursor(QCursor(Qt::BlankCursor));

works
