如何只用一个事件听我的所有组件？

Question

Here is the problem, I have 3 textfield, 3 button and 1 label. Their text are text1, text2 text3, but1,but2,but3.

I give you an example about what I want to do; When I double click on a button, button will change label's text as button's text. I mean when I double click to but2, label's text should be but2.

I can do this with that code;

        MouseAdapter ml = new MouseAdapter() {
            public void mouseClicked(MouseEvent me) {
                if (me.getClickCount()==2) {

                 jLabel1.setText(jButton1.getText);

                }
            }
        };
        jButton1.addMouseListener(ml);

So It works but it works only for jButton1. I have to write different mouseListener's for all components(textfields and jbuttons). How can I do this with one listener? or one event ? Do you have any idea?

Answer 1

Take a look at MouseEvent#getSource ... although, to be honest, if you're using JButton s you shouldn't be using a MouseListener , but ActionListener instead. Also, generally speaking, most users won't double click a JButton as it's not intuitive for them to do so, buttons only need a single click to activate

Remember, buttons can be activated by the keyboard as well, which MouseListener won't be notified about
