Question

I made a small application to open a file and show the contents of opened file in some JTextField and JLabels. I can get all the contents and fill in the TextFields and Labels but the problem is these JLabels and JTextFields are not shown untill and unless I resize(even a little) the windows. I want my contents to be shown straight away. What do I need to do for this.

here is a piece of code to initialize the panel and adding it to scrollpane

        panel = new JPanel();

        scrollPane = new JScrollPane(panel);

In the actionlistener of open button I got the following code

            int returnVal = fc.showOpenDialog(FileReader.this);

            if (returnVal == JFileChooser.APPROVE_OPTION) {
                File file = fc.getSelectedFile();
                String filePath = file.getPath();
               // if(panel.isDisplayable()==true)panel.
                if(scrollPane != null){
                    //panel.removeAll();    
                this.remove(scrollPane);
              //  scrollPane.add(panel);
                    //panel.add(panel);
                    //panel.validate();
                //panel.repaint();

                }
                //pass the file to XMLparser
                xmlParsing = new XMLParsing(filePath); 

                panel = new JPanel();


                panel=fill();
                panel.revalidate();
                panel.repaint();

          scrollPane = new JScrollPane(panel);

                add(scrollPane, BorderLayout.CENTER);
                //add(buttonPanel, BorderLayout.SOUTH);
                saveButton.setEnabled(true);
                saveasButton.setEnabled(true);
