       	source = JAI.create("url", new URL (filename) );
       }
  catch (MalformedURLException e)
  {
	return;
  }

       ImageDisplay canvas = new ImageDisplay(source);

       Font font = new Font("SansSerif", Font.BOLD, 24);
       JLabel title = new JLabel(" Hello World");
       title.setFont(font);
       title.setLocation(0, 32);

       setOpaque(true);
       setLayout(new BorderLayout());
       setBackground(Color.white);

       add(title,  BorderLayout.NORTH);
       add(canvas, BorderLayout.CENTER);
       canvas.setLocation(0, 42);
   }
}

 

Som titel sier får jeg "ImageDisplay cannot be resolved to a type" jeg bruker eclipse som editor. Jeg ville jo tro at koden burde være i orden siden den er rett fra sun sin hjemme side. Men noen som har noen idee om hva som kan være galt?

Eclipse finner vel ikke ImageDisplay da. Kan ikke se den i import'ene dine jeg heller.

 

Edit: importene til Sun, mente jeg ;-)

Hvor fant du dette? Det er ingen ImageDisplay i java API-et. Mulig det er en custom klasse lagd for denne tutorialen. Har du en link?

Det er visst en i JAI, sikkert den som menes. Google litt så finner du.

Mulig du må laste ned JAI ja.

Antar det er gjort siden de JAI-importene som alt er der ikke har gitt feilmeldinger?
