Here's how I solved it with JSNI:
public class AppLoader implements EntryPoint {
private String url, name, features;
public void onModuleLoad() {
initDownload();
Window.open(url, name, features);
}
private static void download(String arg) {
//The arg string now contains stuff from the other browser
window.
Window.alert("Communication across browser windows was
successfull!");
}
public static native void initDownload() /*-{
$wnd.download = function(arg) {
@<packagepath>.AppLoader::download(LJava/lang/String;)(arg);
};
}-*/;
}
public class AppTest implements EntryPoint {
String arg;
public void onModuleLoad() {
if (windowHasParent()) {
submit(arg);
close();
} else {
Window.alert("Please enter app by clicking link ... blah
blah");
}
}
private native boolean windowHasParent() /*-{
if ($wnd.opener == null) {
return false;
} else {
return true;
}
}-*/;
private native void submit(String arg) /*-{
$wnd.opener.download(arg);
}-*/;
private native void close() /*-{
$wnd.close();
}-*/;
}
So basically the AppLoader module is loaded in page 1 and pops up page
2 where the AppTest module is loaded. AppTest sends back any form data
the user entered to AppLoader in page 1. From there AppLoader can send
a formpanel to server to get the response in an iframe.
All the best,
Anders
