OK, well in that case, working with CSS won't be so bad. Now on the SAC page, they have their own implementation, and they also say that Batik has an implementation. What kind of object is "e" where you can call getStyle() on it? Do you use the Batik 1.2 SAC or the standalone SAC 1.3?

There are a number of ways to control them, the simplest is to use the 'presentation attributes' these are normal xml attributes that are "reflected" in the CSS cascade. So assuming nothing else in CSS land is modifying the property on the element you can just do: e.setAttributeNS(null, "display", "none"); This will not win however if there is 'style="display: inline"' for example. So the 'correct' way to do this is with the SAC (Simple API for CSS). This introduces a 'style' member to the element which you can use to get and set properties on the element: e.getStyle().setProperty("display", "none", ""); The third argument can be "!important" which boosts it's priority. Of the two if the element is likely to become visible again later it is best to use 'visibility', there are some issues since visibility can be 'overridden' further down in the tree. Also when visibility is hidden it still takes up memory in the rendering tree. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
