Description:

This is an early preview of the features provided by the prototype of Haskell Web Toolkit (HsWTK), a thin layer on top of DOM which provides basic HTML layout capabilities and simulates cooperative pseudo-threads. HTML widgets displayed are self-explanatory. This demo program is also a memory leak test: please load it into various browsers and notice if browser executable size increases as certain user actions are performed. In fact, there should be no serious leaks, periodic browser size increases were noticed in Microsoft Internet Explorer v6, but at certain moments size decreased due to proper garbage collection. Browser size may even get smaller if the demo program page is unloaded. Mozilla Firefox did not show any memory leaks.
