A Window only has one Control: you pack multiple Controls into a Window by arranging them in layouts (Layouts are also Controls). There are presently two Layouts, Stack and Grid, each with different semantics on sizing and placement. See their documentation. -Once a Window is open, you cannot make layout changes. +Once a Window is open, you cannot make layout or event channel changes. -Once your Window is open, you can begin to handle events.
