In a few places we decided +to chose to depart from Java Swing's architecture. The main differences are: + + In Java Swing all components are containers per default. This doesn't make much sense for + a number of components, like TextField, CheckBox, RadioButton, and so on. Our guess is that + this architecture was chosen because Java lacks multiple inheritance. + In scala.swing, components that can have child components extend the Container trait. + + Layout managers and panels are coupled. There is no way to exchange the layout manager + of a panel. As a result, the layout constraints for widgets can be typed. + (Note that you gain more type-safety and don't loose much flexibility here. Besides + that it is not a common operation, exchanging the layout manager of a panel in Java + Swing almost always leads to exchanging the layout constraints for every of the panel's + child component. In the end, it is not more work to move all children to a newly created + panel.) + + The event system.
