Images einbinden klappt nicht.

[renieh]

Hallo Leute!

Ich versuche gerade verzweifelt ein Bild in meiner Application einzubinden. Es will und will nicht klappen!

Hier die komplette Klasse. Ich schätze mal ich habe etwas grundlegendes falsch.

Ich habe eine Klasse gebaut:

class ClageImage extends Component {
private Image image = Toolkit.getDefaultToolkit().getImage("C:/logo2.jpg");
public void paint( Graphics g ) {
	if ( image != null)
	 System.out.println("painting " + image + " ");
	 g.drawImage( image, 0, 0, this );
}
}

Diese verwende ich mit

ClageImage logo = new ClageImage();

und

panelNorth.add(logo);

Die System.out.println Meldung aus der Klasser erscheint auch. Das Bild aber nicht.

Gruß,
renieh

Hallo!

Wie wär's denn, wenn du zum laden deines Bildes ImageIO.read(...) bzw. die Klasse ImageIcon verwenden würdest. Ich glaube auf den ersten Blick, dass dein Bild wird nicht angezeigt wird, weil es noch nicht vollständig geladen wurde. Früher hat man um diesen Fehler zu vermeiden die Klasse MediaTracker verwendet um das Laden der Resourcen zu überwachen...

Gruß Tom
