MANAJEMEN LAYOUT

Pertemuan 8 :

Dasar Teori

Java menyediakan sejumlah metode layout dalam mengatur penempelan kompenen kedalam frame. Method setlayout() digunakan pada saat pemasangan kompenen.

     A. Metode FlowLayout

 Menempatkan komponen di frame, yang penyusunannya dimulai dari kiri ke kanan dan dari atas kebawah. Secara default, seluruh komponen akan ditampilkan dengan rata tengah,namun metode flowlayout memiliki konstanta LEFT,CENTER, dan RIGHT untuk mengatur perataan komponen yang di inginkan.

.    B. Metode GridLayout

  Metode GridLayout akan membagi area layar menjadi sejumlah tempat dalam bentuk matriks ukuran yang sama. Area kayar dibagi dalam format baris dan kolom. Jadi setiap komponen memiliki ukuran yang sama. Namun setiap kal terjadi perubahan ukuran frame, maka komponennya juga akan berubah. Yang harus dipertahankan adalah jumlah baris dan kolom yang telah ditentukan.

.         C. Metode BorderLayout

      Class BorderLayout memiliki lima konstanta yang menyatakan arah mata angin, yaitu NORTH,EAST,SOUTH,WEST, dan CENTER.

        D. Metode NoneLayout

     Metode ini harus mengatur tap lokasi objek titik demi titik. Tiap objeknya ditentukan oleh koordinat didalam window.

LANGKAH-LANGKAH PRAKTIKUM

1. Membuat 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(tombolEdit);

add(tombolDelete);

pack();

setVisible(true);

setDefaultCloseOperation(EXIT_ON_CLOSE);

 }

}

public class CobaFlowLayout {

public static void main (String[] args) {

FLayout f = new FLayout();

}

Output:

tombolDelete = new JButton("DELETE");

tombolDelete.setMnemonic('D');

tombolCopy = new JButton("COPY");

tombolCopy.setMnemonic('C');

tombolPaste = new JButton("PASTE");

tombolPaste.setMnemonic('P');

setLayout(new GridLayout (3,2));

add(tombolOpen);
