[jboss-user] [JBoss Seam] - Re: Seam and Adobe Flex

[PatrickMadden]

I use ExternalInterface in both directions - Flex/Flash to javascript and javascript to Flex/Flash. In my case user's can use the mouse wheel to zoom in and out on the diagram very easily. In my HTML page I have a toolbar that has a combobox showing the current zoom percent. When users uses mouse wheel inside flex I update the html page dynamically using External Interface method as follows:


  | 		/**
  | 		 * Updates the zoom combobox in the html page owning this movie
  | 		 */
  | 		public function updateZoomComboBox() : void			
  | 		{
  | 			ExternalInterface.call("flashUpdateZoomComboBox",
  | 				String(Math.round(getCloosterApp().getGraphCanvas().scaleX * 100.0)));
  | 		}
  | 

For the reverse direction I first register callbacks with the player. These methods can then be called from javascript.


  | 		/**
  | 		 * The methods below can be called from javascript code in the browser.
  | 		 */
  | 		protected function registerExternalFunctions() : void
  | 		{
  | 			ExternalInterface.addCallback("zoomIn", zoomIn);
  | 			ExternalInterface.addCallback("zoomOut", zoomOut);
  | 			ExternalInterface.addCallback("zoomTo", zoomTo);
  | ...
  | 

It works for me and I would assume you would be able to use the seam remoting as long as you import the seam remoting javascript  file in you xhtlm, or jsp page etc.

Thanks,
