Enable Views to expose "Design Time" default data? about terminal.gui HOT 3 CLOSED

Hmn, I don't think Text should be the place for this. It looks like a string but it behaves like a method.

In general I think properties are not the place for non deterministic behaviours.

Consider the following example:

    [Test]
    public void TestTextSliderString()
    {
        var s1 = new Slider<string>();
        var s2 = new Slider<string>();
        s2.Text = "I've got a lovely bunch of coconuts, here they are sitting in a row!";
     
        // This line does not do what it looks like
        s1.Text = s2.Text;

        TestContext.Out.WriteLine("Options:" + s1.Options.Count); //2
        TestContext.Out.WriteLine("Options:" + s2.Options.Count); //6!

        ClassicAssert.IsTrue(s1.Options.Count == s2.Options.Count );
    }

from terminal.gui.

I think the Text and Title properties should be independent and have no relationship between them. By default, Text will be drawn inside the view, with the exception of custom drawing. The Title should only be used when a view has a border and is not an empty string.

Edit:
This exposition is just to warn you that in this case Options and Text should not have any relationship between them, with the exception that Text can be used to reflect the string that will be displayed relative to the currently selected Options.

I wanted Slider to work in AllViewsTester so I made setting Text to a comma delimited string equivalent to setting Options.

Feel free to undo this, but I'd live ideas on how to make AllViewsTester support causing Views to be "useful/visible" without having custom logic per-view.

I did the same thing to RadioGroup.
