Question

After calling repaint() on a JPanel out of an ActionListener for a JCheckBox, the JPanel has some…issues…they fix themselves upon minimizing and restoring but that’s a hassle for my clients. Any ideas on how to fix this?

Code is below

            JCheckBox curr = new JCheckBox(choices.get(a));
            curr.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e)
                {
                    //System.out.println(((JCheckBox)e.getSource()).getText());
                    if (specs.getSelectedItem()!=null&&!specs.getSelectedItem().toString().isEmpty())
                    {
                        String strSpec = specs.getSelectedItem().toString();
                        if (strSpec.matches("\\w+\\s\\w+"))
                        {
                            Time x = GraphCreator.parseTime(strSpec);
                            GC.getGraph(x);
                            GC.getGraph(x, new Team(((JCheckBox)e.getSource()).getText()));
                        }
                        else
                        {
                            GC.getGraph(new Team(((JCheckBox)e.getSource()).getText()),strSpec.trim());
                        }
                    }
                    pane.repaint();
                }
            });

pane.validate() and pane.repaint() could work. However that’s only when you are adding and removing components that will cause the layout to be affected/altered.
