我如何从 jframe 访问方法到 jpanel？

Question

In my btcFrame class I have the method

private void closeButtonMouseClicked(MouseEvent evt){
        this.dispose();
}

In my BtcTitleBarPanel I have in button for that I tend to close the frame. In the constructor I am adding my listener to closeButton like below.

closeButton.addMouseListener(new MouseAdapter(){
     public void mouseClicked(MouseEvent evt){
         closeButtonMouseClicked(evt);
     }
});

Problem is I cannot reach closeButtonMouseClicked method within the panel. How should I be doing to solve this?

Images in case. Methods from jframe Methods in jpanel

Answer 1

I would add a getter within the Panel for the closeButton . After initializing the Panel in the frame I would add the listener to button within the Frame. Like, btcPanel.getCloseButton().addActionListener(new ...); and within this action listener you could close the frame , like btcFrame.this.dispose() Though I am not sure if that is a good practise, I almost always create new classes for listening events, but in this case of yours maybe helpful.

PS(Out of topic): You should see how to name classes and methods, your naming style is wrong.(ie classes starts with Capital etc.)
