I want to make a VBox with verticalAlign = "middle". Well,
this is easy enough to do if I am doing it in mxml. But I want to
create one dynamically ( am am actually inheriting from VBox). I
can't seemt o get the vertical Alignment to be middle. I have
this.verticalAlign (doen not exist)
this.inheritingStyles.verticalAlign = middle (nope)...
