Hallo, schaut einfach 20 Zeilen hoch, da versuche ich das Fenster mit Namen "Fenster" zu löschen mit Fenster.dispose(); aber die instanz "Fenster" scheint nicht bekannt zu sein?
Code:
import java.awt.Color;
import java.awt.Font;
import java.awt.Insets;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
import org.jvnet.substance.button.ClassicButtonShaper;
