Hi,

How to get graphics or image from visualization component??
i have visualization component the same i  am passing to JFrame tree is displaying in standalone app.
but in WebApplications it is not coming as Jframe will work for standalone  apps.

Component visualizationComponent = gr.getVisualizationComponent(model, ioResult);
visualizationComponent .getGraph()...............>returns null even though visualization.isDisplayable() returns true.
if i use renderer where it will render ?



i want to get the tree and display in Application by setting some variable.

Thanks in advance

    Hi,

    my codeblock from the linked thread paints the tree on any given Graphics object. Please consult Google for details on how to use the graphics context in Java.
