Creating a JTextArea or JEditorPane in a scrollable JFrame

Question

I did some research on Swing to build a css editor with Java. I'm stuck trying to export CSS and HTML to JTextArea (after creating the .css document). Here is the GridLayout that my main layout calls up after clicking on the Create menu item.

package csseditor_gui_built; import java.awt.GridLayout; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTextArea; import javax.swing.JScrollPane; import javax.swing.JScrollBar; import javax.swing.text.DefaultCaret; import java.awt.Font; import java.awt.Color; public class ExportGridLayout extends JFrame { public ExportGridLayout(String HTML, String CSS){ GridLayout layout = new GridLayout(1,2,2,2); setLayout(layout); JTextArea textAreaHtml = new JTextArea(); JTextArea textAreaCss = new JTextArea(); //Creating a new font. Font fontumuz = new Font("Courier New", Font.PLAIN, 12); // Setting constructor strings textAreaHtml.setText(HTML); textAreaCss.setText(CSS); //Additional details.. textAreaHtml.setEditable(false); textAreaCss.setEditable(false); //Appending font to the textArea's textAreaHtml.setFont(fontumuz); textAreaCss.setFont(fontumuz); // Adding the objects to JFrame add(textAreaHtml); add(textAreaCss); } } 

This is pretty straight forward. Just help me add scrollbars or panels to these textArea files. Any other offers on the website do not work.

This is true...

JTextArea text = new JTextArea();

JScrollPane scroll = new JScrollPane(text);

Edited Part

add(scroll);

Here is one working code:

 import java.awt.*; import javax.swing.*; public class JTextAreaExample { private void createAndDisplayGUI() { JFrame frame = new JFrame("JTextArea Scrollable"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel contentPane = new JPanel(); contentPane.setLayout(new GridLayout(1, 2, 2, 2)); JTextArea tArea1 = new JTextArea(); tArea1.setLineWrap(true); JTextArea tArea2 = new JTextArea(); tArea2.setLineWrap(true); tArea1.setText("I got a long long line of text in my JTextArea"); tArea2.setText("I got a long long line of text in my JTextArea"); JScrollPane scroller1 = new JScrollPane(); JScrollPane scroller2 = new JScrollPane(); scroller1.setViewportView(tArea1); scroller2.setViewportView(tArea2); contentPane.add(scroller1); contentPane.add(scroller2); frame.setContentPane(contentPane); frame.setSize(100, 100); frame.setLocationByPlatform(true); frame.setVisible(true); } public static void main(String... args) { SwingUtilities.invokeLater(new Runnable() { public void run() { new JTextAreaExample().createAndDisplayGUI(); } }); } }
