[Htmlparser-developer] RE: [Htmlparser-user] Swing integration

[Craig R. <cr...@qu...>]

Due to time constraints, I've decided to use the HTML parser in Swing
for the time being, but I'd definitely like to see the effect of a
better parser in Swing. Just try a search for 'JEditorPane' in the Bug
Parade and you'll see how long Sun has had issues with this area...

I think your idea of trying the integration after 1.1 release is good.

Hi Craig, Asgher
    I finally had the time to check Swing integration. Boy - the parser
design in Swing sucks!! Theoretically its possible to do it - and I got
started, but just realized that in order to be compatible with swing
objects
that do compile time type checking with a particular tag, I have to
actually
have 73 if statements to give the right tag to the callback.
    I have more important things to do at the moment, but probably will
get
back to this donkey work. *sigh*

    I am thinking we should make release 1.1 and then try this. Any
suggestions ?

Regards,
Somik
