Refresh my page

[rakir]

Hi everybody

I want to refresh my page (F5 behavior) whern i click on a button but i don't know how to do this.

If anyone knows ...

I know that for gxt 1.x, i have to make : XDOM.reload but, nothing happens with that code with gxt 2

Thx a lot

I found this solution using Google.

You can also use:

Window.Location.reload();

XDOM.reload();

works fine for me. I just tested it afew times.

On another note, is there a way to prevent the page refresh when F5 is clicked? Currently when user presses F5 in the browser the whole application reloads and the user gets thrown back to the login screen. I need to stop the browser from refreshing the pages.

I'd recommend looking into the GWT History class, and using that to maintain state...

Browsers have an onBeforeUnload event.

You can only have the browser pop up a native confirm dialog to avoid reloading or browsing away from the page.

Something like this:

        Ext.EventManager.on(window, 'beforeunload', function(e) {
            e.browserEvent.returnValue = 'You have unsaved changes... Press OK to quit anyway.';
        });

Obviously do some logic to decide if you want to do the e.browserEvent.returnValue thing.

Thanks for the tip with onbeforeunload.
I could not find Ext.EventManager.on equivalent in GXT so I put this into my application's html page:

 <script type="text/javascript" language="javascript">
  	var unloadMsg = '';
  	
	function handleBeforeUnload()
	{
	  if (unloadMsg.length > 0)
	  	return unloadMsg; 
	}
	
	window.onbeforeunload = handleBeforeUnload;
  </script>

and then in my code I use this native method to set or clear the unload message as appropriate:

native private static void setUnloadMsg(String msg) /*-{ $wnd.unloadMsg = msg; }-*/;

Try com.google.gwt.user.client.Window.addCloseHandler() - I think this is what you are looking for. RootPanel uses this to detach the objects it builds/finds from the DOM in RootPanel.hookWindowClosing().

Is there a way to prevent the page refresh when you click on F5? Currently, when the user presses F5 in the browser to reload the entire application and the user is returned to the login screen. I need that when you click F5 and all tabpanel tabs remain open.
