[Jscheme-user] Some swing.scm additions

[Borislav I. <bor...@ko...>]

Hi,

I've added a few things jlib/swing.scm that I needed (toolbar and
togglebutton). The additions simply follow the established pattern. What
is the process of submitting a patch? I'm not familiar at all how those
patch file are made and applied :(

And a question: what would be an elegant way to define a paint procedure
for a generic component. Right now, my program has only one Java class
that extends Jcomponent only in order to override the painProc method
(which invokes a scheme procedure). It would be nice to have something
like this:

(component 
  (paint (lambda (graphics) ...do the painting)))

Isn't something of the sort that (canvas) and jlib.SchemeCanvas should
be doing. But I'm not sure it works. There is paintHandler method in
SchemeCanvas, but it doesn't seem to be set anywhere in the generic
construction processing in swing.scm.

Thanks,
Boris
