我在JApplet中创建了一个按钮.如何使用它打开消息框？

okButton = new Button("Miow");
okButton.setBounds(20,20,1150,30);
add(okButton);

//like
if(okButton)
{
    JOptionPane.showMessage......
}

Answer 1

这可能对您有所帮助:

okButton.addActionListener(new MyAction());
public class MyAction implements ActionListener{
  public void actionPerformed(ActionEvent ae){
    JOptionPane.showMessageDialog(null, "This is the simple message 
    dialog box.", "Roseindia.net", 1);
  }
}
