它取决于Java实现。这是您可以运行以查看所有可用属性及其当前值的简单代码。
public static void main(String[] args) { UIDefaults defaults = UIManager.getDefaults(); System.out.println(defaults.size()+ " properties defined !"); String[ ] colName = {"Key", "Value"}; String[ ][ ] rowData = new String[ defaults.size() ][ 2 ]; int i = 0; for(Enumeration e = defaults.keys(); e.hasMoreElements(); i++){ Object key = e.nextElement(); rowData[ i ] [ 0 ] = key.toString(); rowData[ i ] [ 1 ] = ""+defaults.get(key); System.out.println(rowData[i][0]+" ,, "+rowData[i][1]); } Jframe f = new Jframe("UIManager properties default values"); JTable t = new JTable(rowData, colName); f.setContentPane(new JScrollPane(t)); //f.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); f.pack(); f.setVisible(true); }
