Hi,
I am aware of native (JSNI) approach doing this. Involves attaching
unload listener to window. This triggers both on refresh or "hard"
navigation to different url.
public final class MyRefreshListener {
public static void onUnload() {
detachOnUnloadListener();
// Do your stuff here
}
private static native void attachOnUnloadListener() /*-{
$wnd.onunload = function() {
@com.acme.gwt.client.impl.MyRefreshListener::onUnload()
();
}
}-*/;
private static native void detachOnUnloadListener() /*-{
$wnd.onunload = null
}-*/;
}
It could be that on newer GWT version this approach is encapsulated,
but I simply failed to find one.
Hope this helps.
