使用substance美化java界面并解决乱码问题

Contents

使用java做界面，并不怎么美观，可以使用substance包来做美化。但是界面中的中文字符会出现乱码的现象，可以通过设置字体来解决这个问题。首先写使用substance外观的代码，然后在要使窗体显示的代码之前调用一个方法

public static void main(String[] args) throws ClassNotFoundException {
    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                UIManager.setLookAndFeel(new SubstanceOfficeBlue2007LookAndFeel());
                //另外如果想让整体界面变得协调，最好设置容器窗体的DefaultLookAndFeelDecorated属性为true。
                JFrame.setDefaultLookAndFeelDecorated(true);

                //必须在窗体显示前调用
                InitGlobalFont(new Font("Dialog", Font.PLAIN, 14));

                MainFrame frame = new MainFrame();
                frame.setVisible(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}

/**
 * 统一设置字体，父界面设置之后，所有由父界面进入的子界面都不需要再次设置字体
 */
@SuppressWarnings("unchecked")
public static void InitGlobalFont(Font font) {
    FontUIResource fontRes = new FontUIResource(font);
    for (Enumeration<Object> keys = UIManager.getDefaults().keys(); keys
            .hasMoreElements();) {
        Object key = keys.nextElement();
        Object value = UIManager.get(key);
        if (value instanceof FontUIResource) {
            UIManager.put(key, fontRes);
        }
    }
}

这样，程序界面字体就不会乱码了。

还可以自定义一个标题栏，如下面代码所示，然后在创建MainFrame对象之后调用TitlePane.editTitleBar(frame, "标题");即可。
