JAVA Swing - 다른 카드 패널의 카드 패널에서 탭 패널 setSelectedIndex()

Question

다음과 같이 GUI가 있습니다. 카드 레이아웃 card 1의 탭 패널은 기본적으로 첫 번째 탭을 표시합니다. 내가 card 2로 이동하면 card 1 탭 3으로 이동하는 버튼을 만드는 방법을 알고 싶습니다. getParent()을 사용하여 해당 버튼에서 card 1을 얻는 방법을 알고 있지만 특정 탭을 표시하는 방법을 모르겠습니다. 나는 거기에서 원해. (참고 : card 1 및 card 2 두 개의 서로 다른 JPanel의 클래스는, 부모가 JFrame의 클래스가)

Answer 1

나는 당신이 JTabbedPane.html.setSelectedIndex(int)을 찾고 생각합니다.

다음은 가장 훌륭한 해결책은 아니지만 리팩토링을 많이하지 않아도 작동합니다.

는 NewJFrame에 메서드를 추가합니다

public CardLayoutTest.JPanelCard1 getJPanelCard11() { 
    return jPanelCard11; 
} 

는 JPanelCard1에 메서드를 추가합니다

public void setTab(int index) { 
    jTabbedPane1.setSelectedIndex(index); 
} 

전화가 JPanelCard2 이러한 :

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {           
    //show card 1 from here 
    CardLayout card = (CardLayout) this.getParent().getLayout(); 
    card.show((JPanel) this.getParent(), "card1"); 

    //card1 shown, show specific tab in the tab pane from here: 

    NewJFrame parent = (NewJFrame) this.getParent(); 
    ((JPanelCard1) parent.getJPanelCard11()).setTab(1); 
}
