Hello ACE91
basically you do
canvas.getUpdateManager().getBridgeContext()
Note that you have to make sure the document is loaded when you request
the bridge context. This will do the trick:
canvas.addGVTTreeRendererListener(new GVTTreeRendererAdapter() {
public void gvtRenderingCompleted(GVTTreeRendererEvent e) {
canvas.getUpdateManager().getBridgeContext();
}
}
Maybe the bridge context is available even before the GVTTree is
rendered but i'm not 100% sure (anyone?).
In that case you can also call:
canvas.addGVTTreeBuilderListener(new GVTTreeBuilderListenerAdapter() {
@Override
public void gvtBuildCompleted(GVTTreeBuilderEvent e) {
canvas.getUpdateManager().getBridgeContext();
}
});
Hope this helps,
Daniel

Are you getting it from the canvas after the document is loaded?
Because I don't know how to get it any other way, and Batik isn't
well-documented enough for me to find out the right way without scouring the
Javadoc pages for hours, I followed the Batik Wiki's BootSvgAndCssDom
Tutorial. The code that I used is as follows:
UserAgent userAgent;
DocumentLoader loader;
BridgeContext ctx;
userAgent = new UserAgentAdapter();
loader = new DocumentLoader(userAgent);
ctx = new BridgeContext(userAgent, loader);
ctx.setDynamicState(BridgeContext.DYNAMIC);
GVTBuilder builder;
GraphicsNode rootGN;
builder = new GVTBuilder();
rootGN = builder.build(ctx, interfaceDoc);
This is all contained in the JApplet's init() method. Note that interfaceDoc
is the SVGDocument object that contains the scripts that I want to use. This
document has been loaded from a file when the code is executed, but it is
not being displayed in the JSVGCanvas at that moment. It is displayed later,
in another method.
So is there another way to get a BridgeContext object? I tried as hard as I
could, but I couldn't find one. If you could point me to a tutorial or
something, or at least show me how to get the right BridgeContext, that
would be helpful.
