Java API 分類導覽 - java.awt.GridBagLayout

GridBagLayout 類別 (class) 建立格子式的版面編排，可設定元件在第幾個格子，以及垂直或水平佔用的格子數，這些需要另外建立 GridBagConstraints 物件設定相關屬性。



修飾子

java.awt.GridBagLayout

父類別

java.lang.Object

實作介面

LayoutManager
LayoutManager2
Serializable

建構子

GridBagLayout()

舉例如下

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60

import java.awt.*; import java.awt.event.*;   public class GridBagLayoutDemo {     public static void main(String[] args) {         new GridBagLayoutDemo();     }           public GridBagLayoutDemo() {         Frame frame = new Frame("AWTDemo");         frame.addWindowListener(new AdapterDemo());         frame.setLayout(new GridBagLayout());                   Button b1 = new Button("one");         GridBagConstraints c1 = new GridBagConstraints();         c1.gridx = 0;         c1.gridy = 0;         c1.gridwidth = 1;         c1.gridheight = 1;         c1.fill = GridBagConstraints.BOTH;         c1.anchor = GridBagConstraints.CENTER;         frame.add(b1, c1);                   Button b2 = new Button("two");         GridBagConstraints c2 = new GridBagConstraints();         c2.gridx = 1;         c2.gridy = 0;         c2.gridwidth = 1;         c2.gridheight = 1;         c2.fill = GridBagConstraints.BOTH;         c2.anchor = GridBagConstraints.CENTER;         frame.add(b2, c2);                           Button b3 = new Button("three");         GridBagConstraints c3 = new GridBagConstraints();         c3.gridx = 0;         c3.gridy = 1;         c3.gridwidth = 2;         c3.gridheight = 1;         c3.fill = GridBagConstraints.BOTH;         c3.anchor = GridBagConstraints.CENTER;         frame.add(b3, c3);                   frame.pack();         frame.setVisible(true);     }    }   class AdapterDemo extends WindowAdapter {     public void windowClosing(WindowEvent e) {         System.exit(0);     } }   /* 《程式語言教學誌》的範例程式     http://pydoing.blogspot.com/     檔名：GridBagLayoutDemo.java     功能：示範 Java 程式     作者：張凱慶     時間：西元 2012 年 3 月 */

此例將 Frame 設定為 GridBagLayout ，然後建立三個按鈕放入 Frame 之中

14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42

Button b1 = new Button("one"); GridBagConstraints c1 = new GridBagConstraints(); c1.gridx = 0; c1.gridy = 0; c1.gridwidth = 1; c1.gridheight = 1; c1.fill = GridBagConstraints.BOTH; c1.anchor = GridBagConstraints.CENTER; frame.add(b1, c1);           Button b2 = new Button("two"); GridBagConstraints c2 = new GridBagConstraints(); c2.gridx = 1; c2.gridy = 0; c2.gridwidth = 1; c2.gridheight = 1; c2.fill = GridBagConstraints.BOTH; c2.anchor = GridBagConstraints.CENTER; frame.add(b2, c2);                   Button b3 = new Button("three"); GridBagConstraints c3 = new GridBagConstraints(); c3.gridx = 0; c3.gridy = 1; c3.gridwidth = 2; c3.gridheight = 1; c3.fill = GridBagConstraints.BOTH; c3.anchor = GridBagConstraints.CENTER; frame.add(b3, c3);

編譯後執行，結果如下

中英文術語對照
類別	class
建構子	constructor
方法	method
