Announce: FranTk
FranTk (pronounced "frantic") is a declarative library for building GUIs in
Haskell. It's designed to allow you to build your application in a
declarative manner. It uses behaviours and events, concepts from Conal
Elliot's Functional Reactive Animation. These allow you to model a system
over time. Events are used to describe values that occur discretely, such as
button clicks. Behaviors are continuous quantities that vary over time. They
are used to represent the state of an application. Events and behaviors can
interact. For instance, we can have a behavior that changes on every event.
You can then render this application on to an interface.
FranTk provides a full range of widgets for building user interfaces,
including strong support for building interfaces with dynamically changing
numbers of widgets.
FranTk works under hugs98 and ghc-4.04. It uses a number of the extensions
provided by these systems.
FranTk currently lives on top of Tcl-Tk (working via TclHaskell).
It provides a platform independent way to develop GUIs. Tcl-Tk runs on
windows, macs and unix without altering source code, and provides native
look and feel. FranTk has been developed with Tcl8.0. (It should work with
later versions too.) It has, however, been designed to be as tookit
independent as possible and so it should be relatively easy to port to other
GUI toolkits such as java swing.
There is a user manual, and demos directory, with a full range of examples.
