Swing如何使用工具欄JToolBar
工具欄用於存放常用的按鈕
步驟 1 : 工具欄
package gui; import java.awt.BorderLayout; import javax.swing.ImageIcon; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; import javax.swing.JToolBar; public class TestGUI { public static void main(String[] args) { JFrame f = new JFrame("LoL"); f.setSize(400, 300); f.setLocation(200, 200); // 選單 addMenu(f); // 工具欄 JToolBar tb = new JToolBar(); // 為工具欄增加按鈕 JButton b1 = new JButton(new ImageIcon("e:/project/j2se/1.jpg")); JButton b2 = new JButton(new ImageIcon("e:/project/j2se/2.jpg")); JButton b3 = new JButton(new ImageIcon("e:/project/j2se/3.jpg")); JButton b4 = new JButton(new ImageIcon("e:/project/j2se/4.jpg")); JButton b5 = new JButton(new ImageIcon("e:/project/j2se/5.jpg")); JButton b6 = new JButton(new ImageIcon("e:/project/j2se/6.jpg")); tb.add(b1); tb.add(b2); tb.add(b3); tb.add(b4); tb.add(b5); tb.add(b6); // 把工具欄放在north的位置 f.setLayout(new BorderLayout()); f.add(tb, BorderLayout.NORTH); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setVisible(true); } private static void addMenu(JFrame f) { JMenuBar mb = new JMenuBar(); JMenu mHero = new JMenu("英雄"); JMenu mItem = new JMenu("道具"); JMenu mWord = new JMenu("符文"); JMenu mSummon = new JMenu("召喚師"); JMenu mTalent = new JMenu("天賦樹"); // 選單項 mHero.add(new JMenuItem("近戰-Warriar")); mHero.add(new JMenuItem("遠端-Range")); mHero.add(new JMenuItem("物理-physical")); mHero.add(new JMenuItem("坦克-Tank")); mHero.add(new JMenuItem("法系-Mage")); mHero.add(new JMenuItem("輔助-Support")); mHero.add(new JMenuItem("打野-Jungle")); mHero.add(new JMenuItem("突進-Charge")); mHero.add(new JMenuItem("男性-Boy")); mHero.add(new JMenuItem("女性-Girl")); mb.add(mHero); mb.add(mItem); mb.add(mWord); mb.add(mSummon); mb.add(mTalent); f.setJMenuBar(mb); } }
步驟 2 : 給按鈕設定提示資訊
當滑鼠放在按鈕上的時候會出現提示
package gui; import java.awt.BorderLayout; import javax.swing.ImageIcon; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; import javax.swing.JToolBar; public class TestGUI { public static void main(String[] args) { JFrame f = new JFrame("LoL"); f.setSize(400, 300); f.setLocation(200, 200); addMenu(f); JToolBar tb = new JToolBar(); JButton b1 = new JButton(new ImageIcon("e:/project/j2se/1.jpg")); JButton b2 = new JButton(new ImageIcon("e:/project/j2se/2.jpg")); JButton b3 = new JButton(new ImageIcon("e:/project/j2se/3.jpg")); JButton b4 = new JButton(new ImageIcon("e:/project/j2se/4.jpg")); JButton b5 = new JButton(new ImageIcon("e:/project/j2se/5.jpg")); JButton b6 = new JButton(new ImageIcon("e:/project/j2se/6.jpg")); tb.add(b1); tb.add(b2); tb.add(b3); tb.add(b4); tb.add(b5); tb.add(b6); // 給按鈕設定提示資訊 b1.setToolTipText("坑爹英雄"); // 把工具欄放在north的位置 f.setLayout(new BorderLayout()); f.add(tb, BorderLayout.NORTH); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setVisible(true); } private static void addMenu(JFrame f) { JMenuBar mb = new JMenuBar(); JMenu mHero = new JMenu("英雄"); JMenu mItem = new JMenu("道具"); JMenu mWord = new JMenu("符文"); JMenu mSummon = new JMenu("召喚師"); JMenu mTalent = new JMenu("天賦樹"); // 選單項 mHero.add(new JMenuItem("近戰-Warriar")); mHero.add(new JMenuItem("遠端-Range")); mHero.add(new JMenuItem("物理-physical")); mHero.add(new JMenuItem("坦克-Tank")); mHero.add(new JMenuItem("法系-Mage")); mHero.add(new JMenuItem("輔助-Support")); mHero.add(new JMenuItem("打野-Jungle")); mHero.add(new JMenuItem("突進-Charge")); mHero.add(new JMenuItem("男性-Boy")); mHero.add(new JMenuItem("女性-Girl")); mb.add(mHero); mb.add(mItem); mb.add(mWord); mb.add(mSummon); mb.add(mTalent); f.setJMenuBar(mb); } }
步驟 3 : 禁止工具欄拖動
預設情況下 工具欄可以通過滑鼠拖動
setFloatable(false);
可以禁止滑鼠拖動功能
package gui; import java.awt.BorderLayout; import javax.swing.ImageIcon; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; import javax.swing.JToolBar; public class TestGUI { public static void main(String[] args) { JFrame f = new JFrame("LoL"); f.setSize(400, 300); f.setLocation(200, 200); addMenu(f); JToolBar tb = new JToolBar(); JButton b1 = new JButton(new ImageIcon("e:/project/j2se/1.jpg")); JButton b2 = new JButton(new ImageIcon("e:/project/j2se/2.jpg")); JButton b3 = new JButton(new ImageIcon("e:/project/j2se/3.jpg")); JButton b4 = new JButton(new ImageIcon("e:/project/j2se/4.jpg")); JButton b5 = new JButton(new ImageIcon("e:/project/j2se/5.jpg")); JButton b6 = new JButton(new ImageIcon("e:/project/j2se/6.jpg")); tb.add(b1); tb.add(b2); tb.add(b3); tb.add(b4); tb.add(b5); tb.add(b6); b1.setToolTipText("坑爹英雄"); // 禁止工具欄拖動 tb.setFloatable(false); // 把工具欄放在north的位置 f.setLayout(new BorderLayout()); f.add(tb, BorderLayout.NORTH); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setVisible(true); } private static void addMenu(JFrame f) { JMenuBar mb = new JMenuBar(); JMenu mHero = new JMenu("英雄"); JMenu mItem = new JMenu("道具"); JMenu mWord = new JMenu("符文"); JMenu mSummon = new JMenu("召喚師"); JMenu mTalent = new JMenu("天賦樹"); // 選單項 mHero.add(new JMenuItem("近戰-Warriar")); mHero.add(new JMenuItem("遠端-Range")); mHero.add(new JMenuItem("物理-physical")); mHero.add(new JMenuItem("坦克-Tank")); mHero.add(new JMenuItem("法系-Mage")); mHero.add(new JMenuItem("輔助-Support")); mHero.add(new JMenuItem("打野-Jungle")); mHero.add(new JMenuItem("突進-Charge")); mHero.add(new JMenuItem("男性-Boy")); mHero.add(new JMenuItem("女性-Girl")); mb.add(mHero); mb.add(mItem); mb.add(mWord); mb.add(mSummon); mb.add(mTalent); f.setJMenuBar(mb); } }
