Working example:
public class SvgEntryPoint implements EntryPoint {
public class SvgWidget extends Widget {
public SvgWidget() {
setElement(Document.get().createDivElement());
// SVG library should draw inside the widget's container element
drawExample(getElement());
}
private native void drawExample(Element container) /*-{ var draw =
SVG(container)
// Must be used if JS is injected to top window, see below. // var
draw = $wnd.SVG(container)
draw.text('SVG.JS') }-*/;
}
public interface MyBundle extends ClientBundle {
@Source("svg.min.js")
TextResource svgJs();
}
public void onModuleLoad() {
MyBundle bundle = GWT.create(MyBundle.class);
// Injects JS code into the GWT iframe. SvgWidget.drawExample() can use
SVG() then.
ScriptInjector.fromString(bundle.svgJs().getText()).inject();
// Injects JS code into the top level window. Now SvgWidget.drawExample()
MUST use $wnd.SVG()
// to reference the top level window. Only calling SVG() would mean to call
it on the GWT iframe
// to which the JS code has never been injected to.
//ScriptInjector.fromString(bundle.svgJs().getText()).setWindow(ScriptInjector.TOP_WINDOW).inject();
RootPanel.get().add(new SvgWidget());
}
}
