I am trying to implement a callback using JSNI.
1. I don't know if changing "this" is allowed in the way I do it.
2. I don't know if such an assignment is advisable from the perspective of
JSNI functionality
3. The compiler in Eclispe does not seem to grasp that as well and I don't
know the right syntax
for
this.@com.roamtopix.client.StaticFacad.JsCallback::callback.execute(Lcom/google/gwt/core/client/JavaScriptObject;)(jsObject);
with
"callback.execute" it says
"JavaScript parsing: Missing ) after argument list"
for
this.@com.roamtopix.client.StaticFacad.JsCallback::callback::execute(Lcom/google/gwt/core/client/JavaScriptObject;)(jsObject);with
"callback::execute" it says
"JavaScript parsing: Invalid label"
public static interface JavaCallback {
void execute(JavaScriptObject jsObject);
}
public static class JsCallback extends JavaScriptObject {
public final JavaCallback callback;
public JsCallback(JavaCallback callback){
this.callback = callback;
init();
}
private native void init()/*-{
this.@com.roamtopix.client.StaticFacad.JsCallback::that(Lcom/google/gwt/core/client/JavaScriptObject;)(this);
}-*/;
private native void that(JavaScriptObject that)/*-{
var fn = function(jsObject) {
this.@com.roamtopix.client.StaticFacad.JsCallback::callback.execute(Lcom/google/gwt/core/client/JavaScriptObject;)(jsObject);
};
that = $entry(fn);
}-*/;
}
