Add new View with Pos.Right() in event handler not working.

[Corn207]

internal class MainWindow : Window
{
    public MainWindow()
    {
        var addBtn = new Button()
        {
            X = 0,
            Y = 0,
            Text = "Add"
        };

		var uselessBtn = new Button()
		{
			X = Pos.Right(addBtn),
			Y = 0,
			Text = "Useless"
		};

		addBtn.Clicked += () =>
        {
            var newBtn = new Button()
            {
                X = Pos.Right(uselessBtn) + 1,
                Y = 0,
                Text = "New"
            };
            Add(newBtn);
        };

        Add(addBtn, uselessBtn);
    }
}

After pressed:

Add a call to LayoutSubviews (); after adding the button:

var newBtn = new Button () {
	X = Pos.Right (uselessBtn) + 1,
	Y = 0,
	Text = "New"
};
Add (newBtn);
+LayoutSubviews ();

Wow, thanks =))

@tznind this can be avoided if the Window.Redraw call LayoutSubviews ();and then users doesn't needed to call it.
I ran the code in the UICatalog and when I press escape to exit I get this error in the v2_develop branch:

@tig something went wrong in your last merge.
This is the code I used:

		public override void Init ()
		{
			Application.Init ();
			Application.Run (new MainWindow ());
		}
		internal class MainWindow : Window {
			public MainWindow ()
			{
				var addBtn = new Button () {
					X = 0,
					Y = 0,
					Text = "Add"
				};

				var uselessBtn = new Button () {
					X = Pos.Right (addBtn),
					Y = 0,
					Text = "Useless"
				};

				addBtn.Clicked += (s, e) => {
					var newBtn = new Button () {
						X = Pos.Right (uselessBtn) + 1,
						Y = 0,
						Text = "New"
					};
					Add (newBtn);
					LayoutSubviews ();
				};

				Add (addBtn, uselessBtn);
			}
		}

I do not think Redraw should call LayoutSubviews - this is a cause performance issues (and spaghetti code) in v1.

In v2 we will be enforcing that Layout is decoupled from Drawing. If, when Redraw is called layout is needed, we'll wait until the next MainLoop iteration to call LayoutSubviews.

In v2 is OK for the layout engine to call Redraw, but not the other way around.

I think the View.Redraw is calling LayoutSubviews before draw his subviews and not calling LayoutSubviews to itself.
