问题描述
我一直在尝试重载JMenu并添加一些自定义代码来支持JTextField,但这并不顺利。我的主要目的是在菜单项的右侧添加一个搜索字段。所以我有左边的文件,编辑,帮助,然后右边是搜索栏,几乎就像在某些浏览器中有一个谷歌搜索栏。有没有人知道如何添加此功能?
I've been trying to overload JMenu and put in some custom code to support a JTextField but that isn't going well. My main purpose here is to add a search field to the right of my menu items. So I have something like File, Edit, help on the left and then on the right would be the search bar, almost like how there is a google search bar in some browsers. Does anyone have an idea how I could go about adding this functionality?
推荐答案
我从未将其视为 JMenuItem
,我认为alyways放在 JMenuBar
I never see that as JMenuItem
, I think that alyways placed in JMenuBar
import java.awt.ComponentOrientation;
import javax.swing.*;
public class MenuGlueDemo {
public MenuGlueDemo() {
JMenuBar menuBar = new JMenuBar();
menuBar.add(createMenu("Menu 1"));
menuBar.add(createMenu("Menu 2"));
menuBar.add(createMenu("Menu 3"));
menuBar.add(new JSeparator());
menuBar.add(new JButton(" Seach .... "));
menuBar.add(new JTextField(" Seach .... "));
menuBar.add(new JComboBox(new Object[]{"height", "length", "volume"}));
menuBar.add(Box.createHorizontalGlue());
menuBar.add(createMenu("About"));
JFrame frame = new JFrame("MenuGlueDemo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(menuBar);
frame.pack();
frame.setVisible(true);
}
public JMenu createMenu(String title) {
JMenu m = new JMenu(title);
m.add("Menu item #1 in " + title);
m.add("Menu item #2 in " + title);
m.add("Menu item #3 in " + title);
if (title.equals("About")) {
m.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
}
return m;
}
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
MenuGlueDemo menuGlueDemo = new MenuGlueDemo();
}
});
}
}
