SVGUserAgentGUIAdapter
public class SVGUserAgentAdapter extends java.lang.Object implements SVGUserAgent
This Implements the SVGUserAgent interface to provide a very simple version of client services to the JSVGComponent. This implementation does not require any GUI interaction to work. This implementation is particularly bad about user interaction most of the alert,prompt,etc methods are totally useless. In a GUI environment you probably want to use SVGUserAgentGUIAdapter.- Version:
