Visual Editor in Eclipse Galileo
For a long time I have tried to install Visual Editor into my Eclipse Galileo and never get it work until recently.
The secret is explained in the Wiki:
With “Eclipse IDE for Java EE Developers”, you should NOT check the Java EMF Model Utilities (org.eclipse.jem.util) plugins since there are already installed.
Ugh… I think I have tried it before but why only now it is working? Anyway, I’m glad that I have it.
For those who are not aware, Visual Editor is an GUI editor for Eclipse. It can be used to assist Swing or SWT application creation. I never like Netbeans Matisse or SWT Designer because I can’t modify the code like I want. I know that Visual Editor is pretty slow, but to get a code that I can enhance manually tastes better than the alternative.
And more importantly, I like the way it codes my Swing application. Here’s an example:
import java.awt.BorderLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JSlider;
import javax.swing.JTextField;
import javax.swing.SwingConstants;
public class TTT extends JFrame {
private static final long serialVersionUID = 1L;
private JPanel jContentPane = null;
private JLabel jLabel = null;
private JButton jButton = null;
private JTextField jTextField = null;
private JSlider jSlider = null;
/**
* This is the default constructor
*/
public TTT() {
super();
initialize();
}
/**
* This method initializes this
*
* @return void
*/
private void initialize() {
this.setSize(300, 196);
this.setContentPane(getJContentPane());
this.setTitle("JFrame");
}
/**
* This method initializes jContentPane
*
* @return javax.swing.JPanel
*/
private JPanel getJContentPane() {
if (jContentPane == null) {
jLabel = new JLabel();
jLabel.setText("JLabel");
jContentPane = new JPanel();
jContentPane.setLayout(new BorderLayout());
jContentPane.add(jLabel, BorderLayout.CENTER);
jContentPane.add(getJButton(), BorderLayout.EAST);
jContentPane.add(getJTextField(), BorderLayout.SOUTH);
jContentPane.add(getJSlider(), BorderLayout.NORTH);
}
return jContentPane;
}
/**
* This method initializes jButton
*
* @return javax.swing.JButton
*/
private JButton getJButton() {
if (jButton == null) {
jButton = new JButton();
jButton.setHorizontalAlignment(SwingConstants.TRAILING);
jButton.setText("Test");
jButton.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent e) {
System.out.println("actionPerformed()"); // TODO Auto-generated Event stub actionPerformed()
}
});
}
return jButton;
}
/**
* This method initializes jTextField
*
* @return javax.swing.JTextField
*/
private JTextField getJTextField() {
if (jTextField == null) {
jTextField = new JTextField();
jTextField.addKeyListener(new java.awt.event.KeyAdapter() {
@Override public void keyTyped(java.awt.event.KeyEvent e) {
System.out.println("keyTyped()"); // TODO Auto-generated Event stub keyTyped()
}
});
}
return jTextField;
}
/**
* This method initializes jSlider
*
* @return javax.swing.JSlider
*/
private JSlider getJSlider() {
if (jSlider == null) {
jSlider = new JSlider();
}
return jSlider;
}
} // @jve:decl-index=0:visual-constraint="10,10"
See how it creates a getter for every components? The getter should prepare a component with its properties and also its listener initialization. It makes every method pretty small and readable. There is no long methods with several components and listeners initialization.
