        {
            Application.Init();
            var container = new View() { Id = "Container", X = Pos.Center(), Y = Pos.Center(), Width = 16, Height = 16 };
            var top = new FrameView() { Id = "Top", Width = Dim.Fill(), Height = 12 };
            var bottom = new FrameView() { Id = "Bottom", Y = Pos.Bottom(top), Width = Dim.Fill(), Height = 4 };

            };
            top.Add(label);
            container.Add(top, bottom);
            Application.Top.Add(container, debugLabel);

            Application.RootMouseEvent += (me) => Top_Resized(null, top, bottom, label, me);
            Application.Top.Resized += (obj) => Top_Resized(obj, top, bottom, label);
            Application.Run();

            return;
        }

        private static void Top_Resized(Size? obj, View top, View bottom, View label, MouseEvent? me = null)
        {
            top.GetCurrentWidth(out int topWidth);
            top.GetCurrentHeight(out int topHeight);
            bottom.GetCurrentWidth(out int bottomWidth);
            bottom.GetCurrentHeight(out int bottomHeight);
            label.GetCurrentWidth(out int labelWidth);
            label.GetCurrentHeight(out int labelHeight);
                       
            var sb = new StringBuilder();
            sb.AppendLine("Mouse");
            sb.AppendLine("###############");
            sb.AppendLine($"X: {me?.X}, Y: {me?.Y}");
            sb.AppendLine($"Under cursor: {me?.View.Id}");
            sb.AppendLine();
            sb.AppendLine("Size");
            sb.AppendLine("###############");
            sb.AppendLine($"Top: [{topHeight}, {topHeight}]");
            sb.AppendLine($"Bottom: [{bottomHeight}, {bottomHeight}]");
            sb.AppendLine($"Label: [{labelHeight}, {labelHeight}]");

            debugLabel.Text = sb.ToString();
        }
    }
}
