Invoking Java from Javascript using BrowserComponent and not using Deprecated Classes

[x3.m...@gmail.com]

Hi guys,
I just love CN1 and am playing around with the Java/Javascript interoperability in the BrowserComponent.
The problem I have is that the working code has deprecated classes and I cannot find a good example of how to do it without using deprecated code.

Currently this works :
        JavascriptContext ctx = new JavascriptContext(browser);
        JSObject test = (JSObject) ctx.get("window");
        test.set("call", new JSFunction() {
            public void apply(JSObject self, Object[] args) {
                String msg = (String) args[0];
                System.out.println("window.call was executes");
            }
        });
Deprecated classes: JavascriptContext,JSObject
Please give me a hint on how to NOT use the deprecated Classes to call Java from Javascript.

Use BrowserComponent.addJSCallback() instead.  Some examples in the GoogleMaps lib

https://github.com/codenameone/codenameone-google-maps/blob/master/GoogleMaps/src/com/codename1/googlemaps/MapContainer.java#L352

Yours would be something like

myBrowserComponent.addJSCallback("window.test=function(msg){callback.onSuccess(msg)}", msg -> {

    String msgStr = msg.stringValue();

    System.out.println(msgStr);

});
