Swing MakeOver / SwingX

Swing MakeOver :

Teknik memanipulasi tampilan user interface (Java Swing). Teknik ini dilakukan dengan menggunakan penggambaran agar tampilan komponen-komponen Java Swing seperti TextField, Button, dan lain-lain menjadi tampak lebih cantik

SwingX :

Salah satu ‘turunan‘ dari Swing yang bisa digunakan seorang progammer jika bosan dengan Swing, atau menginginkan fitur-fitur tambahan pada Swing. Komponen pada SwingX hampir sama dengan komponen pada Swing, contoh pada Swing terdapat komponen JList, JTable, JComboBox dan pada SwingX komponen tersebut menjadi JXList, JXTable, JXComboBox.

Kelebihan SwingX 

• Terdapat  fungsi addHighlighter() yang digunakan untuk memberi highlight pada sel tertentu (bisa berupa warna background berbeda dan sebagainya)

•  SwingX juga menawarkan komponen baru, seperti JXDatePicker. Ini adalah contoh komponen yang sering dibutuhkan oleh aplikasi, tetapi tidak disediakan oleh Swing secara langsung.

•  SwingX juga memiliki kotak dialog siap pakai, seperti JXTipOfTheDay, yang umum dipakai untuk menampilkan tips di program.

Mouse Event pada Listener

     Halo semuanya, kali ini saya akan membagikan lagi salah satu fitur GUI yang ada di JAVA. itu adalah Mouse Event pada Listener. Event-Listener adalah pattern yang sangat penting dan banyak digunakan dalam aplikasi. Semua event dalam Swing menggunakan pattern ini secara extensive. Event Listener adalah class yang mengimplementasikan interface <type>Listener. Di bawah ini adalah salah satu contoh projectnya, langsung aja deh cekidot :
Ini adalah Tampilannya :

Ini adalah Syntax dari contoh project diatas : 

package testjeni2;

import java.awt.*;

import java.awt.event.*;

public class MouseEventsDemo extends Frame implements

MouseListener, MouseMotionListener {

TextField tf;

public MouseEventsDemo(String title){

super(title);

tf = new TextField(60);

addMouseListener(this);

}

public void launchFrame() {

/* Menambah komponen pada frame */

add(tf, BorderLayout.SOUTH);

setSize(300,300);

setVisible(true);

}

public void mouseClicked(MouseEvent me) {

String msg = "Mouse clicked.";

tf.setText(msg);

}

public void mouseEntered(MouseEvent me) {

String msg = "Mouse entered component.";

tf.setText(msg);

}

public void mouseExited(MouseEvent me) {

String msg = "Mouse exited component.";

tf.setText(msg);

}

public void mousePressed(MouseEvent me) {

String msg = "Mouse pressed.";

tf.setText(msg);

}

public void mouseReleased(MouseEvent me) {

String msg = "Mouse released.";

tf.setText(msg);

}

public void mouseDragged(MouseEvent me) {

String msg = "Mouse dragged at " + me.getX() + "," +

me.getY();

tf.setText(msg);

}

public void mouseMoved(MouseEvent me) {

String msg = "Mouse moved at " + me.getX() + "," +

me.getY();

tf.setText(msg);

}

public static void main(String args[]) {

MouseEventsDemo med = new MouseEventsDemo("Mouse Events Demo");

med.launchFrame();

}

}

Sekian dari saya, bila ada kekurangan mohon dimaafkan, Thanks.
