Personally I've always had a through dislike for Swing, and now I'm
looking into its implementation I dislike it even more. Replacing
Swing entirely would be something I could seriously delve into!
I like the idea of using a XAML style layout-file to create UIs. A
threadsafe Swing replacement which would parse these at runtime, or
something that would complie a layout-file into bytecode are two
options off the top of my head. Would most of you like standard
library of windows and dialogs in Clojure? < A list of suggested
essentials windows and dialogs would be appreciated.
Are there any examples of GUI libraries designed for the functional
programming model that you know of I could go examine first? Purely
from a syntax point of view. Lispers? Is there such as thing
already?
