Pertemuan 11, Komponen Swing

Komponen-Komponen Swing

Swing merupakan alternatif untuk mengimplementasikan program Window. Walaupun diimplementasikan berdasarkan kelas AWT, Swing tidak menggunakan komponen-komponen yang terdapat pada AWT, sehingga tampilan komponen- komponen dalam Swing tidak tergantung pada sistem Window local. Dengan demikian tampilan dari grafik Swing untuk semua sistem operasi menjadi serupa. JComponen merupakan super kelas bagi sejumlah kelas, misalanya JComboBox, JLabel, JList, dan JPanel dll.
Berikut ini merupakan beberapa kelas yang terdapat dalam package javax.swing yang sering dipergunakan.

A.Membuat program contoh dari JLabel dan 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);

Pertemuan 10. JMENU

JMENU

 Menu adalah komponen yang berbentuk grup fungsi prosesyang berkaitan dengan fitur-fitur suatu aplikasi. Kelas JMenu Bar Mengimplementasikan bar yang didalamnya terdapat obyek-obyek menu yang bersifat pull down (dapat ditekan). Kelas JMenuItem digunakan untuk menyusun item menu berupa teks atau label, termasuk membuat shortcut dari tombol-tombol keyboard. Kelas JMenu digunakan untuk menginstans obyak-obyek pull down menu yang akan diletakka apd amenu bar.

Pertemuan 9 EventHandling

EVENT HANDLING

    Event Handling adalah suatu metode untuk menangani sebuah  event/aksi yang di berikan pengguna kepada suatu komponen GUI. Event adalah suatu peristiwa yang dipicu oleh pengguna pada suatu komponen, misalnya tombol di tekan.  Dua paket yang biasa digunakan untuk menangani kejadian adalah java.awt.event dan javax.swing.event.  Event Handling dalam menangani Event terbagi menjadi tiga macam yaitu :

1. Event Source
    Event Source adalah komponen yang mendapatkan suatu event yang kemudian ditangkap oleh Event Listener. Event Source dapat dibedakan dari penamaan komponen itu sendiri, misalnya tombol Simpan, tombol Hapus, dll.

2. Event Listener
    Event Listener digunakan untuk menangkap Event yang terjadi pada komponen /Event Source.

3. Event Handler
    Event Handler berupa blok method dari Listener yang menentukan proses selanjutnya setelah komponen mendapatkan Event. Misalkan pada tombol Event Source event tombol Simpan
ditekan, event Listener akan menangkap event pada Event Source tombol Simpan, kemudian Event Handler akan menyimpan data yang didefinisikan pada blok Event Handler.
