PERTEMUAN 8 MANAJEMEN LAYOUT

DASAR TEORI

Manajemen pemasangan komponen (manajemen layout) diperlukan untuk mengatur penempatan komponen di dalam frame agar bisa menghasilkan bentuk interface yang menarik.

A.Metode FlowLayout

      Metode FlowLayout menempatkan komponen di frame berdasarkan urutan komponen-komponen tersebut ditempelkan ke frame.

B. Metode GridLayout

      Metode GridLayout akan membagi area layar menjadi sejumlah tempat dalam bentuk matriks ukuran yang sama.

C.Metode BorderLayout

      Metode BorderLayout menggunakan konsep arah mata angin dalam memasang komponen.

D.Metode NoneLayout

      Metode NoneLayout tidak cukup fleksibel digunakan. Oleh karena itu harus mengatur lokasi tiap objek titik demi titik.

Contoh Program

A.Program CobaFlowLayout.java

import java.awt.*;

import javax.swing.*;

class FLayout extends JFrame {

JButton tombolSave, tombolEdit, tombolDelete, tombolOpen;

public FLayout() {

setTitle("FLOWLAYOUT");

tombolOpen = new JButton("OPEN");

tombolOpen.setMnemonic('O');

tombolSave = new JButton("SAVE");

tombolSave.setMnemonic('S');

tombolEdit = new JButton("EDIT");

tombolEdit.setMnemonic('E');

tombolDelete = new JButton("DELETE");

tombolDelete.setMnemonic('D');

setLayout(new FlowLayout());

add(tombolOpen);

add(tombolSave);

add(tombolDelete);

pack();

setVisible(true);

setDefaultCloseOperation(EXIT_ON_CLOSE);
