Komponen-Komponen Swing Lanjutan

Selain dari JComboBox, JLabel, JList, dan JPanel, masih banyak lagi komponen dalam swing diantaranya JFileChooser, JTabbedPane, JTable, JTree. Namun untuk saat ini saya hanya akan memberikan contoh program yang menggunakan JFileChooser, JTabbedPane, dan JTable saja.

A. Membuat Program contoh dari JLabel dab JButton menggunakan icon dan Tool Tip

import javax.swing.*;
import java.awt.*;

public class cthIcon{
public static void main (String[] args){
JFrame myFrame = new JFrame (“Contoh program AWT”);
Icon ikon = new ImageIcon (“0002.GIF”);
JLabel myLabel = new JLabel (“Selamat belajar JAVA”, ikon, SwingConstants.CENTER);
JButton myButton = new JButton (“SELESAI”, ikon);
myButton.setToolTipText (“ini adalah Button”);
myLabel.setToolTipText (“ini adalah Label”);
myFrame.setLayout (new BorderLayout());
myFrame.add (myLabel, “South”);
myFrame.add (myButton, “North”);
myFrame.setSize (500,500);
myFrame.setVisible (true);
myFrame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
}
}

B. Membuat Program Menggunakan JFileChooser

import javax.swing.*;
import javax.swing.filechooser.*;
import java.io.File;

public class ContohJFileChooser extends JFrame{
public static void main (String [] args) {
ContohJFileChooser apl = new ContohJFileChooser();
}

public ContohJFileChooser() {
setSize (400,150);
JFileChooser jfc = new JFileChooser();
FileFilter filterDotJava = new Akhiran(“.java”, “Berkas*.java”);
jfc.setFileFilter (filterDotJava);
int hasil = jfc.showOpenDialog (this);
if (hasil == JFileChooser.APPROVE_OPTION)
setTitle (“Tes JFileChooser. File: ” + jfc.getSelectedFile().getName());
else
setTitle (“Tes JFileChooser. Batal memilih”);
setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
setVisible (true);
}
}

class Akhiran extends FileFilter{
private String ekstensi;
private String keterangan;

public Akhiran (String suffix, String deskripsi){
this.ekstensi = suffix;
this.keterangan = deskripsi;

}

public boolean accept (File f) {
if (f.isDirectory())
return true;
return f.getName().endsWith(ekstensi);
}

public String getDescription() {
return keterangan;
}
}

C. Membuat Program dengan menggunakan JTextArea, JList dan JSpinner

import javax.swing.*;
import javax.swing.event.*;
import java.awt.*;

class cthList extends JFrame{
JList daftar;
JTextArea tArea1, tArea2;
JPanel Panel1, Panel2, Panel3, Panel4;
JSpinner Spin;
String daftarBunga[] = {“Melati”, “Mawar”, “Krisan”, “Kenanga”, “Cempaka”, “Tulip”, “Kamboja Jepang”};

public cthList() {
super (“Tes JList”);
setSize (350,300);
Spin = new JSpinner();
Spin.setValue (new Integer (10));

Panel1 = new JPanel();
Panel2 = new JPanel();
Panel3 = new JPanel();
Panel4 = new JPanel();

daftar = new JList(daftarBunga);
daftar.setSelectedIndex(0);

tArea1 = new JTextArea(“”,3, 15);
tArea1.setEditable(false);
tArea2 = new JTextArea(“”,3, 15);
tArea2.setEditable(false);

setLayout (new BorderLayout());

add(Panel1, “North”);
add(Panel2, “West”);
add(Panel3, “East”);
add(Panel4, “South”);
Panel1.add(daftar);
Panel2.add(tArea1);
Panel3.add(tArea2);
Panel4.add(Spin);

setDefaultCloseOperation(3);
setVisible (true);

daftar.addListSelectionListener(new ListSelectionListener(){
public void valueChanged(ListSelectionEvent e){
tArea1.setText(“Yang terpilih: \n” +daftar.getSelectedValue());
}
}
);

Spin.addChangeListener(new ChangeListener() {
public void stateChanged(ChangeEvent e){
tArea2.setText(“Nilai: \n” +Spin.getValue());
}
}
);
}
}

public class ContohList{
public static void main (String [] args){
cthList apl = new cthList();
}
}

D. Membuat Program dengan menggunakan JProgressBar

 import javax.swing.*;
import javax.swing.event.*;
import java.awt.*;
import java.awt.event.*;

class CthJProgressBar extends JFrame implements ActionListener{
public final static int SELANG_WAKTU_TUNGGU = 1;
public final static int MAKS = 1000;

JProgressBar pb;
JButton b;
Timer timer;
int posisi = 0;

public CthJProgressBar() {
super(“Tes JProgressBar”);
setSize(300,120);
pb = new JProgressBar(0, MAKS);
b = new JButton(“Mulai”);
JPanel p = new JPanel();
p.add(b);
setLayout(new BorderLayout());
add(“North”, p);
add(“South”, pb);

timer = new Timer(SELANG_WAKTU_TUNGGU, new ActionListener(){
public void actionPerformed(ActionEvent evt){
posisi++;
pb.setValue(posisi);
if (posisi == MAKS){
timer.stop();
b.setText(“Mulai”);
}
}
}
);

b.addActionListener(this);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible (true);
}

public void actionPerformed(ActionEvent e){
String s = e.getActionCommand();
if (s.equals(“Mulai”)){
b.setText(“Stop”);
posisi = 0;
pb.setValue(posisi);
timer.start();
}
else{
b.setText(“Mulai”);
timer.stop();
}
}
}

public class ContohProgressBar{
public static void main (String [] args){
CthJProgressBar apl = new CthJProgressBar();
}

E. Membuat Program dengan menggunakan JTabbedPane

import javax.swing.*;

class CthJTabbedPane extends JFrame{
JLabel lTab1, lTab2, lTab3, lTab4;
JTabbedPane tab;

public CthJTabbedPane() {
super (“Tes JTabbedPane”);
setSize(300,120);

tab = new JTabbedPane();

JPanel panel1 = new JPanel();
tab.addTab(“Satu”, panel1);
tab.setSelectedIndex(0);
lTab1 = new JLabel(“Tab Satu”);
panel1.add(lTab1);

JPanel panel2 = new JPanel();
tab.addTab(“Dua”, panel2);
lTab2 = new JLabel(“Tab Dua”);
panel2.add(lTab2);

JPanel panel3 = new JPanel();
tab.addTab(“Tiga”, panel3);
lTab3 = new JLabel(“Tab Tiga”);
panel3.add(lTab3);

JPanel panel4 = new JPanel();
tab.addTab(“Empat”, panel4);
lTab4 = new JLabel(“Tab Empat”);
panel4.add(lTab4);

add(tab);

setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
setVisible (true);
}
}

public class ContohJTabbedPane{
public static void main (String [] args){
CthJTabbedPane apl = new CthJTabbedPane();
}
}

F. Membuat Program dengan menggunakan JTable

import javax.swing.*;

}

public ContohJTable() {
super(“Tes JTable”);
setSize(500,150);

Object[][] data = {
