JPanel의 내가 목록 수평 같은 JScrollPane의에 패널을 삽입 할

안녕을 작동하지 않습니다,하지만 난 설정보다 패널의 경계를 존중하지 않는이 내 코드 ItemCurso이 JPanel의에서, 마지막 확장JPanel의 내가 목록 수평 같은 JScrollPane의에 패널을 삽입 할

public PrincipalPanel() { 
     initComponents(); 
     for(int i=0;i<3;i++){ 
      addItem(new ItemCurso(),i); 
     } 
    } 

    public void addItem(ItemCurso item,int index){ 
     item.setVisible(true); 
     item.setBounds(400*index, 0, 400, 300); 
     jScrollPane1.getViewport().add(item,null); 
    }

입니다 ItemCurso 내가 JScrollPane의 크기를 가져옵니다 설정하고 스크롤

을 작동하지 않습니다 ItemCurso의 코드는 다음과 같습니다

public class ItemCurso extends javax.swing.JPanel { 

    public ItemCurso() { 
     initComponents(); 
    }

'ItemCurso' 클래스의 코드가 필요합니다. 그것 없이는'setBounds()'의 구현을 볼 수 없다. –

ok, 잠시 기다리십시오. –

생성 된 코드를 포함하여 모든 코드가 필요합니다. –

jScrollPane1.getViewport().add(item,null);

뷰포트에 "항목"을 3 개 추가 할 수 없습니다. 단일 컴포넌트 만 뷰포트에 추가 할 수 있습니다. 기본적으로

JPanel panel = new JPanel(); // specify your layout manager here 

for(int i=0;i<3;i++) 
{ 
    panel.add(new ItemCurso()); 
} 

jScrollPane1.getViewport().add(panel);

가 JPanel 그래서 모든 구성 요소가 같은 줄에 수평으로 표시됩니다 FlowLayout 사용

그래서 당신의 논리는 다음과 같이해야한다.

Dimension (400, 300)을 반환하도록 ItemCurso 클래스에 getPreferredSize() 메서드를 구현해야합니다. setBounds (...)를 사용하지 마십시오.
