e870. getting the default values for a look and feel.txt

这里面包含了一百多个JAVA源文件

This example demonstrates how to retrieve all the default values for the current look and feel. 
    // Get the currently installed look and feel
    UIDefaults uidefs = UIManager.getLookAndFeelDefaults();
    
    // Retrieve the keys. Can't use an iterator since the map
    // may be modified during the iteration. So retrieve all at once.
    String[] keys = (String[])uidefs.keySet().toArray(new String[0]);
    
    for (int i=0; i<keys.length; i++) {
        Object v = uidefs.get(keys[i]);
    
        if (v instanceof Integer) {
            int intVal = uidefs.getInt(keys[i]);
        } else if (v instanceof Boolean) {
            boolean boolVal = uidefs.getBoolean(keys[i]);
        } else if (v instanceof String) {
            String strVal = uidefs.getString(keys[i]);
        } else if (v instanceof Dimension) {
            Dimension dimVal = uidefs.getDimension(keys[i]);
        } else if (v instanceof Insets) {
            Insets insetsVal = uidefs.getInsets(keys[i]);
        } else if (v instanceof Color) {
            Color colorVal = uidefs.getColor(keys[i]);
        } else if (v instanceof Font) {
            Font fontVal = uidefs.getFont(keys[i]);
        } else if (v instanceof Border) {
            Border borderVal = uidefs.getBorder(keys[i]);
        } else if (v instanceof Icon) {
            Icon iconVal = uidefs.getIcon(keys[i]);
        } else if (v instanceof javax.swing.text.JTextComponent.KeyBinding[]) {
            javax.swing.text.JTextComponent.KeyBinding[] keyBindsVal =
                (javax.swing.text.JTextComponent.KeyBinding[])uidefs.get(keys[i]);
        } else if (v instanceof InputMap) {
            InputMap imapVal = (InputMap)uidefs.get(keys[i]);
        } else {
            // Unknown type
        }
    }
