When the user cancels or finishes the purchase, Paypal redirects the user
to a page within the iframe or popup window. My cancel URL looks like this
http://127.0.0.1:8888/xxx.html?gwt.codesvr=127.0.0.1:9997#!homePage;cancel=true.
I am using GWTP so the following code should give you an idea on how it
works:
@Override
public void prepareFromRequest(PlaceRequest placeRequest) {
super.prepareFromRequest(placeRequest);
String cancel = placeRequest.getParameter("cancel", "");
if ("true".equals(cancel)) {
paypalClose();
}
}
public static native void paypalClose() /*-{
if (top && top.opener && top.opener.top) {
top.opener.top.dgFlow.closeFlow();
top.close();
} else if (top) {
top.dgFlow.closeFlow();
top.close();
}
}-*/;
top.close() will close the paypal flow (iframe or popup window).
