Des Weiteren bräuchte ioch mal ne idee für einen Timer, der das ganze Refreshed :/ mit den Thread.sleep(1000) klappt das nicht... da erscheint das Applet garnicht erst

Danke schonmal

Zeig mal HTML.

btw.
Hä? :noe:

SwingUtilities.invokeAndWait(new Runnable() {
	public void run() {
		TestCounter count = new TestCounter();
		count.setVisible(true);
	}
});
....
setSize(248, 173);

Ich vermute, du versuchst den Konstruktor der Klasse zu blockieren. Geht natürlich nicht, da du damit die init aufhalten würdest. Ist aber schwer zu sagen, ab Zeile 104 ist es ein erstklassiges Beispiel, warum man keine GUI-Builder verwenden sollte. Schau dir mal Threads an, sind imho einen Tick einfacher als Timer.

 

[fl_ex]

Stinknormale HTML:

<applet code="TestCounter.class" width="350" height="350">
Test-Countdown
</applet>

Ja, Gui-Builder ist aber vom Komfort ganz gut ;P

was kann ich da nu also machen? :/

 

[Volvagia]

Versuch mal das:

<applet code="countdown.TestCounter.class" width="350" height="350">
Test-Countdown
</applet>

Der Browser muss aber wahrscheinlich neu gestartet werden, wenn du die Datei veränderst.

Ja, Gui-Builder ist aber vom Komfort ganz gut ;P

Aber nur, wenn du die Klasse danach nie wieder angreifst.

Wenn ich mit Eclipse Run As --> Applet mache funktioniert alles!

 

[Volvagia]

Sorry das es ein wenig gedauert hat, hab beim Testen einen Packagefehler gemacht, der mir erst spät aufgefallen ist.
Bei mir funktioniert es so. Liegt die *.class denn im Verzeichnis "countdown"?
Also so z. B.:

Webspaceroot bzw. htdocs
	index.htm
	countdown
		TestCounter.class

 

[fl_ex]

hab die *.class aufm Desktop und die *.html ebenso... da ist kein extra Ordner "countdown" soll ich den anlegen? Oder wie meinst du das?

Desktop__
TestCounter.class
TestCounter.html

 

[Volvagia]

Ja. Und nur die class reinlegen.

 

[fl_ex]

okay... nun erscheint kein Fehler mehr, aber es kommt auch garnix

 

[Volvagia]

Verstehe ich nicht, bei mir funktioniert das problemlos. ???:L

 

[fl_ex]

YES! aus irgendwelchen Gründen geht es jetzt
hehe TOP...
Kannst mit vllt noch helfen mit nem Timer so?...Weiß nicht wie ich den darein kriege... :/

 

[Volvagia]

Du willst die Methode bloß jede Sek. aufrufen, oder? Dann löse es doch simple so:
