So ändern Sie Java Cardlayout aus einer anderen separaten Klasse
Bitte ich habe versucht, CardLayout von einer anderen Klasse (JPanel) zu wechseln, die eine der Karten im CardLayout ist. Ich habe lange danach gesucht und recherchiert, fand aber nichts hilfreiches.
Ich habe ein CardLayout und zwei separate JPanels, die ich zum CardLayout hinzugefügt habe. Jetzt möchte ich in der Lage sein, die Karten zu wechseln, nachdem ich Aktivitäten mit dem separaten JPanel oder der separaten Klasse ausgeführt habe. Wie wechsle ich das CardLayout von einer anderen Klasse? Mein Code unten.
package myApp;
import java.awt.CardLayout;
public class TestmyCard extends javax.swing.JFrame {
/**
* Creates new form TestmyCard
*/
public TestmyCard() {
initComponents();
jPanel1.add(new FirstCard(),"card3");
jPanel1.add(new SecondCard(),"card4");
}
public void chgCard(String nwCard){
CardLayout cl = (CardLayout)(jPanel1.getLayout());
cl.show(jPanel1,nwCard);
}
