What's the way to find the Window that references UserControl?

[IronEaterBeast]

There is a button in UserControl, and I need to use ShowDialog to open a window when the button is clicked, but I haven't found a good way.

private void XApiSetting_Click(object? sender, RoutedEventArgs e)
{
    var apiWindow = new ApiSettings();
    //apiWindow.ShowDialog((MainWindow)(((Button)sender).GetVisualRoot()));
    //apiWindow.Show();
}

You can use the TopLevel APIs.

https://docs.avaloniaui.net/docs/concepts/toplevel

EG

var window = TopLevel.GetTopLevel(this) as Window;

Windows themselves inherit from TopLevel

Avalonia/src/Avalonia.Controls/WindowBase.cs

Line 18 in 42aa77e

public class WindowBase : TopLevel

But you should probably still check if the top level is actually a window as there are a few things that implement it which you may run into depending on how your app runs. That said I have never seen it return anything but a Window when running a desktop app. Not sure what it returns on non desktop apps.
