WinUI3: How to hide the mouse cursor

[AliGuemues]

Hello,

I am developing a WinUI3 application and want to hide the mouse cursor after some seconds of inactivity, or generally want to hide the cursor in some cases.

I searched a lot on the internet but didn´t find anything helpful for my case. Is it possible to achieve something like this?

As ShowCursor only works for Win32 controls,
a way is with InputDesktopResourceCursor.CreateFromModule and a custom empty cursor in a DLL
then set_ProtectedCursor with Reflection

Is this supposed to work on Pages?

I'm trying to hide the cursor using the code below, but it only hides it only when it's on a control (Buttons, ColorPickers, etc).

private void Button_Click(object sender, RoutedEventArgs e)
{
    // Get an empty cursor from resources.
    InputCursor emptyCursor = GetEmptyCursor();

    // Call this method using Reflection.
    // IUIElementProtectedMethods.set_ProtectedCursor(_objRef_global__Microsoft_UI_Xaml_IUIElementProtected, value);
    if (Assembly.GetAssembly(typeof(UIElement)) is Assembly assembly &&
        assembly.GetType("ABI.Microsoft.UI.Xaml.IUIElementProtectedMethods") is Type targetType &&
        targetType.GetMethod(
            "set_ProtectedCursor",
            BindingFlags.Static | BindingFlags.Public | BindingFlags.Instance) is MethodInfo methodInfo &&
        typeof(UIElement).GetProperty(
            "_objRef_global__Microsoft_UI_Xaml_IUIElementProtected",
            BindingFlags.NonPublic | BindingFlags.Instance) is PropertyInfo propertyInfo &&
            propertyInfo.GetValue(this) is IObjectReference objectReference)
    {
        methodInfo.Invoke(this, new object[] { objectReference, emptyCursor });
    }
}
