Swing如何使用工具栏JToolBar

工具栏用于存放常用的按钮

步骤 1 : 工具栏

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);
        // 菜单
        addMenu(f);

        // 工具栏
        JToolBar tb = new JToolBar();
        // 为工具栏增加按钮
        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);

        // 把工具栏放在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("召唤师");
        JMenu mTalent = new JMenu("天赋树");

        // 菜单项
        mHero.add(new JMenuItem("近战-Warriar"));
        mHero.add(new JMenuItem("远程-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("辅助-Support"));
        mHero.add(new JMenuItem("打野-Jungle"));
        mHero.add(new JMenuItem("突进-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);
    }
}

步骤 2 : 给按钮设置提示信息

当鼠标放在按钮上的时候会出现提示

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);

        // 给按钮设置提示信息
        b1.setToolTipText("坑爹英雄");

        // 把工具栏放在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("召唤师");
        JMenu mTalent = new JMenu("天赋树");

        // 菜单项
        mHero.add(new JMenuItem("近战-Warriar"));
        mHero.add(new JMenuItem("远程-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("辅助-Support"));
        mHero.add(new JMenuItem("打野-Jungle"));
        mHero.add(new JMenuItem("突进-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);
    }
}

步骤 3 : 禁止工具栏拖动

默认情况下 工具栏可以通过鼠标拖动
setFloatable(false);

可以禁止鼠标拖动功能

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");

        // 禁止工具栏拖动
        tb.setFloatable(false);

        // 把工具栏放在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("召唤师");
        JMenu mTalent = new JMenu("天赋树");

        // 菜单项
        mHero.add(new JMenuItem("近战-Warriar"));
        mHero.add(new JMenuItem("远程-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("辅助-Support"));
        mHero.add(new JMenuItem("打野-Jungle"));
        mHero.add(new JMenuItem("突进-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);
    }
}
