copied!<p>For a beginner to Java Swing, try to keep this project simple. To show multiple colors and multiple sizes in the same document requires a lot of complex coding and rendering html.</p> <p>Try to just provide the basic copy,cut,paste features because they are easier to implement.</p> <p>To provide those features, a JTextArea is sufficient.</p> <p>Try this. It's a pretty simple text editor</p> <pre><code>import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Document extends JFrame implements ActionListener { private JTextArea ta; private int count; private JMenuBar menuBar; private JMenu fileM,editM,viewM; private JScrollPane scpane; private JMenuItem exitI,cutI,copyI,pasteI,selectI,saveI,loadI,statusI; private String pad; private JToolBar toolBar; public Document() { super("Document"); setSize(600, 600); setLocationRelativeTo(null); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Container pane = getContentPane(); pane.setLayout(new BorderLayout()); count = 0; pad = " "; ta = new JTextArea(); //textarea menuBar = new JMenuBar(); //menubar fileM = new JMenu("File"); //file menu editM = new JMenu("Edit"); //edit menu viewM = new JMenu("View"); //edit menu scpane = new JScrollPane(ta); //scrollpane and add textarea to scrollpane exitI = new JMenuItem("Exit"); cutI = new JMenuItem("Cut"); copyI = new JMenuItem("Copy"); pasteI = new JMenuItem("Paste"); selectI = new JMenuItem("Select All"); //menuitems saveI = new JMenuItem("Save"); //menuitems loadI = new JMenuItem("Load"); //menuitems statusI = new JMenuItem("Status"); //menuitems toolBar = new JToolBar(); ta.setLineWrap(true); ta.setWrapStyleWord(true); setJMenuBar(menuBar); menuBar.add(fileM); menuBar.add(editM); menuBar.add(viewM); fileM.add(saveI); fileM.add(loadI); fileM.add(exitI); editM.add(cutI); editM.add(copyI); editM.add(pasteI); editM.add(selectI); viewM.add(statusI); saveI.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_S, ActionEvent.CTRL_MASK)); loadI.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_L, ActionEvent.CTRL_MASK)); cutI.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_X, ActionEvent.CTRL_MASK)); copyI.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_C, ActionEvent.CTRL_MASK)); pasteI.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_V, ActionEvent.CTRL_MASK)); selectI.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_A, ActionEvent.CTRL_MASK)); pane.add(scpane,BorderLayout.CENTER); pane.add(toolBar,BorderLayout.SOUTH); saveI.addActionListener(this); loadI.addActionListener(this); exitI.addActionListener(this); cutI.addActionListener(this); copyI.addActionListener(this); pasteI.addActionListener(this); selectI.addActionListener(this); statusI.addActionListener(this); setVisible(true); } public void actionPerformed(ActionEvent e) { JMenuItem choice = (JMenuItem) e.getSource(); if (choice == saveI) { //not yet implmented } else if (choice == exitI) System.exit(0); else if (choice == cutI) { pad = ta.getSelectedText(); ta.replaceRange("", ta.getSelectionStart(), ta.getSelectionEnd()); } else if (choice == copyI) pad = ta.getSelectedText(); else if (choice == pasteI) ta.insert(pad, ta.getCaretPosition()); else if (choice == selectI) ta.selectAll(); else if (e.getSource() == statusI) { //not yet implmented } } public static void main(String[] args) { new Document(); } </code></pre>
