Swing高级控件

这篇文章给大家演示一下Swing中的高级控件的用法，为了方面大家入门，我们的示例将会尽可能的简化。Swing中的高级控件包括JTabbedPane（页签）,JPanel（面板）,JDesktopPane（桌面窗格）,JInternalFrame（内部窗口）,JProgressBar（进度条）,JTree（树）,JMenuBar（菜单栏）,JPopupMenu（右键菜单）,JToolBar（工具栏）,JSplitPane（分隔窗格）,JTable（表格）,JSlider（滑动栏）等。运行效果如下：

代码如下：

import java.awt.*;

import java.awt.event.*;

import java.net.URL;

import javax.swing.*;

import javax.swing.border.*;

import javax.swing.tree.*;

 *,JInternalFrame,JProgressBar,JTree,JMenuBar,JPopupMenu,JToolBar,JSplitPane

 *,JTable,JSlider等)的基本用法，这里只是来个大杂烩，在实际应用中要注意取舍，灵活机变。
