Blazor Hybrid window move event?

I've been trying to find how to register the move event of any of the windows types in a blazor hybrid app.

All of these have a SizeChanged event or similarly named, but none of them something like Position/LocationChanged event / OnMove/d, etc.

Microsoft.Maui.Controls.Window
Microsoft.UI.Windowing.AppWindow
Microsoft.UI.Windowing.OverlappedPresenter

#if WINDOWS So, is there a way to detect the window movement? Even if we need to stoop low, pun intended. #endif

WebView2 should support this, as the appWindow of Tauri does have an onMoved event. Or I suppose it comes from WebView2.

This has been corrected; otherwise it would have been super useful: https://github.com/dotnet/maui/issues/17991

You could use the PropertyChanged event.

public partial class App : Application
{
  public App()
  {
    InitializeComponent();
  }

  protected override Window CreateWindow(IActivationState? activationState)
  {
    var window = new Window(new MainPage()) { Title = "MauiApp7" };

    // Add a PropertyChanged event handler
    window.PropertyChanged += Window_PropertyChanged;

    return window;
  }

  private void Window_PropertyChanged(object? sender, System.ComponentModel.PropertyChangedEventArgs e)
  {
    // Check if the X or Y property changed
    if (e.PropertyName == nameof(Window.X) || e.PropertyName == nameof(Window.Y))
    {
      var window = (Window)sender!;
      // Execute your code here when X or Y changes
      window.Title = $"Window X position changed to: {window.X}, {window.Y}";
    }
  }
}
