Hi John,<br><br>I'm not sure how to interpret your remarks about "has no effect" and "is best". I guess they're subjective opinions, but maybe I'm missing something objective in your intent. I can see, for instance, at least one way in which layout has a direct and enormous effect on interaction semantics. And while I can see some benefits in choosing CSS, I also see some significant drawbacks, and I wonder if you've factored these drawbacks into your "is best".<br>

<br> The actual presentation and layout of widgets would be better handled by a DSL such as CSS (which is, in fact, declarative in nature), while event logic would be best handled purely in Haskell.<br> <br> Regards,<br> <br>

toolkits, and replace them with something "genuinely functional", which for<br> me means having a precise & simple compositional (denotational) semantics.<br> Something meaningful, formally tractable, and powefully compositional from<br>
the ground up. As long as we build on complex legacy libraries (Gtk,<br> wxWidgets, Qt, OpenGL/GLUT, ...), we'll be struggling against (or worse yet,<br> drawn into) their ad hoc mental models and system designs.<br>
<br> As Meister Eckhart said, "Only the hand that erases can write the true<br> thing."<br> </blockquote> <br> I think working on a purely functional widget toolkit would actually<br> be a really cool project. Do you have any ideas, though, on what<br>
should be the underlying primitives?<br> <br> The initial gut feeling I have is that one should just ignore any<br> notion of actually displaying widgets & instead focus on a clean<br> algebra of how to 'add' widgets that relates the concepts of<br>
inheritance & relative position. What I mean by inheritance, here, is<br> how to direct a flow of 'events'. I don't necessarily mean events in<br> the Reactive sense, because I think it'd be important to make the<br>
model completely independent of how time & actual UI actions are<br> handled.<br> <br> Any thoughts to throw in, here?<br> <br> Cheers,<br> C<br></div></div><div> _______________________________________________<br> Haskell-Cafe mailing list<br>
