Views - View.Height += 1 does not have the expected behavior

Before I use view.Height = view.Subviews.Count;, I had it in another way where I did view.Height += 1; I remove a lot of other views with Dim and Pos to other views, thinking maybe was circular reference or something. But no, the problem is just that line … view.Height += 1;

If you try this, it gets exponentially slower.

This is beacuse Dim.Combine. After 3 times, view.Height == {Dim.Combine(Dim.Combine(Dim.Combine(Dim.Absolute(0)+Dim.Absolute(1))+Dim.Absolute(1))+Dim.Absolute(1))}

Is this the expected behavior for this case ???

Maybe if it’s the same instance, combine should behave differently, because I think that view.Height += x is something very basic to have such a behavior.

public override void Setup ()
{
  var view = new View () { X = 0, Y = 0, Width = 20, Height = 0 };
  var field = new TextField () { X = 0, Y = Pos.Bottom (view), Width = 20 };
  
  field.KeyDown += (k) => {
	  if (k.KeyEvent.Key == Key.Enter) {
  
		  var label = new Label (field.Text) { X = 0, Y = view.Subviews.Count, Width = 20 };
		  
                  field.Text = "";
  
		  view.Add (label);
  
                  // works
		  view.Height = view.Subviews.Count;
                  
                  // don't try this at home
		  // view.Height += 1;
	  }
  };
  
  Win.Add (view);
  Win.Add (field);
}

@BDisp Sorry I couldn’t help you.

That is the way that Pos and Dim works, but why don’t do that?

view.Height = view.Bounds.Height + 1;

Yes, there are many ways to do this, but I think that operators should work as expected.
