Masking the viewport or content panel

[the.wizard]

Hello everyone,
I have a problem with masking the viewport or content panel. Right now in my application, I have a button that when I clicked it, it will call the setUrl method in the content panel (or TabItem). What I want to achieve is, when the TabItem loading the URL, the parent container will set to mask (so the user can't do anything with the application). The problem is I can't find any event to listen when the TabItem loading the URL. Is there anyone who has the same experience / problem? Please kindly advice me.

Thanks.

Hi.

TabItem.setUrl returns the iFrame and you can add a load handler to that.

panel.mask();
t1.setUrl("http://www.sencha.com").addLoadHandler(new LoadHandler() {
    @Override
        public void onLoad(LoadEvent event) {
        panel.unmask();
    }
});

});

Hi Ersmarker,
I have tried your solution, but it appears that TabItem doesn't have any method like addLoadHandler. It only had addAttachHandler, AddDOMHandler, and AddHandler. Please explain more detail about your solution. Really thanks a lot for helping me.

You don't add the LoadHandler directly on the tabItem, But on the Frame returned by tabItem.getUrl(url);

                panel.mask();
                Frame frame = tab1.setUrl("http://www.sencha.com");
                frame.addLoadHandler(new LoadHandler() {
                    @Override
                    public void onLoad(LoadEvent event) {
                        panel.unmask();
                    }
                });

                    }
                });

But the frame itself really don't have method addLoadHandler. I am using gwt 2.2, which gwt version do you use?
Thanks.

The frame.addLoaderHandler was added in GWT 2.3

The frame.addLoaderHandler was added in GWT 2.3

Can I still do it in gwt 2.2.0? Right now I will stick with gwt 2.2.0 because I use mvp4g (which is currently only support for gwt 2.2.0).
Please kindly advice me.

Thanks.
