RAP 4.4 ClientCanvas - how to get details of the drawn items

[JohnGymer]

I am making use of RAP 4.4's new ClientCanvas to capture (for example) a customer signature.

ClientDrawListener cltcanvDrawLsnr = new ClientDrawListener() { @Override public void receivedDrawing() { System.out.println("cltcanvDrawLsnr#receivedDrawing"); } };

The listener is correctly triggered, but I see no API to get details of what the user drew onto the ClientCanvas... how can I do this to capture the drawing either as a vector (points array) or a bitmap?

For now use internal API ClientCanvas.getAdapter( DrawingsCache.class ).

Thanks Ivan, I'll take a look into getAdapter and the DrawingsCache.

I can get my build to work OK referencing DrawingsCache by adding an access rule:

However, at runtime, the DrawingsCache class cannot be found - can you give some hints on how to change the runtime configuration to also have this class accessible?

java.lang.ClassNotFoundException: org.eclipse.rap.rwt.addons.internal.canvas.DrawingsCache cannot be found by uk.co.iet.rapide.raponly_5.0.0
