Re: batik not updating when resizing

Hi,

Thanks for your response.

I think I got Batik wrong, sorry I'm noob with DOM and Batik. I was 
expecting Batik to intercept the events from DOM, so it is aware when 
something in the XML changed and render what needed again. Can't I do 
that? Then if I want to change, lets say the colour of my form, what 
would be the proper way to achieve that? Do I really need to override 
all the internal Canvas functions that performs the render of my object?

Thanks
Ruben
