KOMPONEN - KOMPONEN SWING LANJUTAN

Pertemuan 11 :

Dasar Teori 

Swing merupakan alternatif lain untuk mengimplementasikan pemograman Wndows. Walaupun diimplementasikan berdasarkan kelas AWT,Swing tidak menggunakan komponen - komponen yang terdapat pada AWT,sehingga tampilan - tamplan komponen - komponen dalam Swing tidak tergantung pada sistem Window local.Dengan demikian tampilan grafik dari Swing untuk semua system operasi menjadi serupa.JComponen merupakn super kelas bagi sejumlah kelas,misalnya JComboBox,JLabel,JList dan JPanel dan lainnya.

LANGKAH - LANGKAH PRATIKUM          



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");

JMenu

Pertemuan 10 :

Dasar Teori

Menu adalah komponen yang berbentuk grup fungsi pemproses yang berkaitan dengan fitur-fitur suatu aplikasi. Kelas JMenuBar mengimplementasikan bar yang didalamnya terdapat obyek-obyek menu yang bersifat pull down ( dapat ditekan). Kelas JMenuItem digunakan untuk menyusun item menu yang berupa teks atau label,termasuk membuat shortcut dari tombol-tombol keyboard. JMenu digunakan untuk menginstants obyek-obyek pull down menu yang akan diletakkan pada menu bar.
