ContentPane To make the content pane visible to the application, declare the getContentPane() method as public. In addition, insert the initialization of the sliders into this method. Also, you can now insert all setLabelFor() methods, because after the execution of the method body, you can be sure that all tar- get objects of setLabelFor() exist. public javax.swing.JPanel getContentPane() { if(contentPane == null) { contentPane = new javax.swing.JPanel();
