Java jButton을 두 번 클릭해야 액티비티가 시작됩니다.

Question

병원 장비 프로젝트의 주입 펌프를 나타내는 GUI를 Netbeans 7.1에 구축하고 있습니다. jButton1을 누르면 jLabel이 표시되어 주입이 실행 중임을 나타냅니다. jButton1을 다시 누르면 중지됩니다. 내가 가지고있는 유일한 문제는 그것이 처음 작동하기 전에 버튼을 두 번 클릭해야한다는 것입니다. 그 후, 그것이 작동하도록 정확히 작동합니다. 이 문제에 대해 여러 스레드를 검색했지만 다른 솔루션이 작동하지 않는 것 같습니다. 누구든지 나를 도울 수 있습니까? 미리 감사드립니다!

package infusion; 
    public class Infusion { 
    static Interface screen; 

    public Infusion(){ 

     screen = new Interface(); 
     screen.setVisible(true); 
     screen.jLabel3.setVisible(true); 
     screen.jButton1.setVisible(true); 
    }  

    public static void main(String[] args) { 
     // TODO code application logic here 
     Infusion infusion = new Infusion(); 
    } 
    } 

이것은 대부분 Netbeans에서 생성 한 사용자 인터페이스 코드입니다. jButton1ActionPerformed의 구현은 내가 채택한 유일한 코드 비트입니다.

package infusion; 

    public class Interface extends javax.swing.JFrame { 
     boolean pump1Running = false; 
     /** 
     * Creates new form Interface 
     */ 
     public Interface() { 
      initComponents(); 
     }

Answer 1

문제 : 버튼을 클릭하면 pump1Running = 거짓, 그래서, 그것으로 시작하는 것입니다 같은 일에 라벨과 이미지를 설정합니다. 그런 다음 사실로 전환 한 다음 다른 레이블/이미지로 전환 할 수 있습니다.

 if (pump1Running){ 
      jLabel3.setIcon(new ImageIcon(getClass().getResource("/Pauze.png"))); 
      jLabel3.setText("Infusion Paused"); 
      jButton1.setText("Start Infusion"); 
      pump1Running = !pump1Running; 
     } 
     else {//if (pump1Running == true){ 
      jLabel3.setIcon(new ImageIcon(getClass().getResource("/Pauze.png"))); 
      jLabel3.setText("Running infusion"); 
      jButton1.setText("Stop Infusion"); 
      pump1Running = !pump1Running; 
     } 

펌프 1을 앞뒤로 전환하고 문제를 해결합니다.
