General

Hi,

I need to get the height and width of browser’s client.
The following code gives infos about the name of the browser, but doesn’t give the dimensions.
Where i am wrong ?


public class Launcher extends Application {

	@Override
	public void init() {
		Window main = new Window("Hello window");
		setMainWindow(main);
		main.addComponent(new Label("Hello World!"));

		
		ApplicationContext context = this.getContext();
		if (context instanceof WebApplicationContext) {
		       String userAgent = ((WebApplicationContext)this.getContext()).getBrowser().getBrowserApplication();
		       System.out.println("appli context : "+userAgent);
		       int a = ((WebApplicationContext)this.getContext()).getBrowser().[color=#e80d40]
getScreenHeight();
[/color]
		       int b = ((WebApplicationContext)this.getContext()).getBrowser().[color=#e80d40]
getScreenWidth();
[/color]
		       boolean boo = ((WebApplicationContext)this.getContext()).getBrowser().isFirefox();
		       System.out.println("Height : "+a+", Width: "+b+", isfirefox : "+boo);
		}
	}
}

Result :
appli context :
Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; … .NET4.0E; BRI/2; InfoPath.3)


Height: 0, Width: 0
,
isfirefox : false
