다른 클래스에서 정의되고 JFrame에서 사용되는 JButtton의 리스너

Question

나는 작업을하고 있습니다. 여기이 프레임에서 'Add Record'버튼을 클릭하면 JPanel 클래스를 확장하여 정의 된 Jframe에 패널을 추가합니다. 이제 Panel에서 생성 된 'save'버튼 클릭시에 패널에 정의 된 textFields에서 Text를 가져 와서 변수에 저장하려고합니다. 버튼 클릭시 아무 것도 저장되지 않습니다. 도와주세요. 미리 감사드립니다.

Answer 1

, 이러한 이벤트를 생성 할 수있는 일이 없을 것. 이 두 줄을 actionPerformed에서 frontPage 또는 다른 초기 화 함수로 이동해보십시오.

public void actionPerformed(ActionEvent ae) 
{ 
    panelAddForm addform = new panelAddForm(); 
    addform.save.addActionListener(this); 
    ... 
}
