Coming in the next build of LaunchE
The first build of LaunchE that is online now is pretty basic. We considered waiting to make more progress but it made sense to try to get it out in the public sooner and get feedback as soon as possible. So please, let us know what you think either in the comments here or by email. We also welcome code submissions as long as you are willing to grant us the necessary copyright so that we can continue with our existing license.
Also I thought it would be useful to give everyone a heads up on the next things that are coming in the library. RadioButton and ScrollBar are both pretty much done and after that we will probably start working on some layout concepts like Grid.
One important decision that we are still wrestling with is control composition. Real WPF controls are all pretty much built out of other controls and can have any other controls embedded in them. In that model ScrollBar gets built out of 5+ other controls for the various regions.
So far we are not taking the same approach for LaunchE. My concern is that the quantity of controls was sometimes a perf issue even with compiled C# code, with the JavaScript platform we need to be careful to make sure it runs fast enough. So ScrollBar is itself one control that deals with its own sub-parts. This reduces some degree of flexibility, but I hope to still enable a Button control that has arbitrary other stuff embedded for its content.
