Code below is untested:
public class GraphicsWidget extends Widget
{
private static boolean injected = false;
public GraphicsWidget()
{
if (!injected)
{
MyGraphics.injectSnap ();
injected = true;
}
// set empty div as widget element:
Element e = Document.get().*createElement("svg"); // Snap() needs a svg
element, see docs.*
setElement(e);
}
public void test () // called from Dialog Box
{
Element e = getElement();
testLib(e);
}
private native void testLib (Element container)
/*-{
var s = $wnd.Snap (container); *// should work now*
var c = s.circle (150,150,100);
}-*/;
}
