Mouse events in QML rendered using QQuickRenderControl

[LoneWolf10]

Greetings,
I have tried to implement QML rendering into QOffscreenSurface and using this as a texture in OpenGL (same as example provided by Qt). I am also trying to implement mouse events so that if a user clicks on the QML interface it will respond (I have tried the QML with ToggleButton and some buttons that change the text color in a Text). I am using

void UIRenderer::mousePress(double x,double y)
{
    QPointF pos(x*WINDOW_WIDTH,y*WINDOW_HEIGHT);
    QMouseEvent mappedEvent(QEvent::MouseButtonPress, pos, Qt::MouseButton::LeftButton, Qt::MouseButton::LeftButton, Qt::NoModifier);
    QCoreApplication::sendEvent(m_quickWindow, &mappedEvent);
}

void UIRenderer::mouseRelease(double x,double y)
{
    QPointF pos(x*WINDOW_WIDTH,y*WINDOW_HEIGHT);
    QMouseEvent mappedEvent(QEvent::MouseButtonRelease, pos, Qt::MouseButton::LeftButton, Qt::MouseButton::LeftButton, Qt::NoModifier);
    QCoreApplication::sendEvent(m_quickWindow, &mappedEvent);
}

where x = [0..1] and y = [0..1] represent mouse event location. The problem is that when I click on some button and then I click on some other buttons the first clicked button responds (regardles of where the click event occured). I am certain that I missed something. Could you please help?

Thank you.

Could you post some minimal working example for others to test out?
