GUI Programing Swing이란?

Swing Programing Frame Content Pane Content. Pane은 JPanel로 만든다. 우리는이 Content. Pane을 꾸미면 된다.

Swing Programing import javax. swing. JFrame; import javax. swing. JPanel; import javax. swing. JText. Field; public class Hello. Swing { public static void main(String[] args) { JFrame fr = new JFrame("This 프레임 "); JPanel pn = new JPanel(); JText. Field tf = new JText. Field(); pn. add(tf); fr. set. Content. Pane(pn); tf. set. Text("This is 텍스트"); fr. set. Size(300, 200); fr. set. Visible(true); } }

Swing Programing Java문법 – package와 import package는 class를 담는 그릇 package를 만들지 않았다면 default package에 담긴다.

Swing Component Label Component Frame Content Pane List Component

Swing Component import javax. swing. JFrame; import javax. swing. JPanel; import javax. swing. JText. Field; public class Hello. Swing { public static void main(String[] args) { JFrame fr = new JFrame("This 프레임 "); JPanel pn = new JPanel(); JText. Field tf = new JText. Field(); pn. add(tf); fr. set. Content. Pane(pn); tf. set. Text("This is 텍스트"); fr. set. Size(300, 200); fr. set. Visible(true); } } JText. Field역시 Component이다.

Swing Component package com. jiharu. main; import javax. swing. JButton; javax. swing. JFrame; javax. swing. JPanel; javax. swing. JText. Field; public class Main { public static void main(String[] args) { JFrame fr = new JFrame("This 프레임"); JPanel pn = new JPanel(); JText. Field tf = new JText. Field(); JButton btn = new JButton(); pn. add(tf); pn. add(btn); fr. set. Content. Pane(pn); tf. set. Text("텍스트"); btn. set. Text("버튼"); fr. set. Size(300, 200); fr. set. Visible(true); } }

Swing Layout 해당 component들을 contentpane에 어 떻게 부착했을까?

Swing Layout은 Component를 Container(Paner)에 배치하는 방법

Swing Layout – Flow Layout import java. awt. Flow. Layout; import javax. swing. JButton; import javax. swing. JFrame; import javax. swing. JPanel; public class Test. Swing { public static void main(String[] args) { JFrame fr = new JFrame("This 프레임"); JPanel pn = new JPanel(); JButton[] bt = new JButton[10]; Flow. Layout fl = new Flow. Layout(); fl. set. Alignment(Flow. Layout. CENTER); pn. set. Layout(fl); for (int i = 0; i < bt. length; i++) { bt[i] = new JButton("Button" + i); pn. add(bt[i]); } fr. set. Content. Pane(pn); fr. set. Size(400, 300); fr. set. Visible(true); } }

Swing Programing Java문법 – 배열 초기화 기본 타입의 경우 int num[10] = new int[10]; for(int i=0; i<10; i++){ num[i] = I; } 참조(객체, 클래스) 타입의 경우 Object obj[10] = new Object[10]; for(int i=0; i<10; i++){ Object = new Object(i); -> 각각의 생성자를 호출한다. }

Swing Layout – Border Layout import java. awt. Border. Layout; import javax. swing. JButton; import javax. swing. JFrame; import javax. swing. JPanel; public class Test. Swing { public static void main(String[] args) { JFrame fr = new JFrame("This 프레임"); JPanel pn = new JPanel(); JButton[] bt = new JButton[5]; Border. Layout fl = new Border. Layout(); pn. set. Layout(fl); for (int i = 0; i < bt. length; i++) { bt[i] = new JButton("Button" + i); pn. add(bt[i]); } pn. add(bt[0], Border. Layout. NORTH); pn. add(bt[1], Border. Layout. EAST); pn. add(bt[2], Border. Layout. CENTER); pn. add(bt[3], Border. Layout. WEST); pn. add(bt[4], Border. Layout. SOUTH); fr. set. Content. Pane(pn); fr. set. Size(400, 300); fr. set. Visible(true); } }

Swing Layout 내용이 매우 길어져서 블로그 참조: http: //kamang-it. tistory. com/118

Swing Layout – Grid Layout import java. awt. Grid. Layout; import javax. swing. JButton; import javax. swing. JFrame; import javax. swing. JPanel; public class Test. Swing { public static void main(String[] args) { JFrame fr = new JFrame("This 프레임"); JPanel pn = new JPanel(); JButton[] bt = new JButton[4]; Grid. Layout gl = new Grid. Layout(2, 2); pn. set. Layout(gl); for (int i = 0; i < bt. length; i++) { bt[i] = new JButton("Button" + i); pn. add(bt[i]); } pn. add(bt[0]); pn. add(bt[1]); pn. add(bt[2]); pn. add(bt[3]); fr. set. Content. Pane(pn); fr. set. Size(400, 300); fr. set. Visible(true); } }
