Swing 知识点

常用Swing知识点、技巧总结，逐步积累添加中

1、如何给JPanel，JFrame，JDialog设置背景

2、如何去掉JTextField中输入文本框时的跟随方框
     System.setProperty("java.awt.im.style", "on-the-spot");
3、表格间隔色
JTable table = new JTable() {
   public Component prepareRenderer(TableCellRenderer renderer, int row, int column) {
    Component prepareRenderer = super.prepareRenderer(renderer, row, column);
    if (row % 2 == 0) {
     prepareRenderer.setBackground(Color.LIGHT_GRAY);
    } else {
     prepareRenderer.setBackground(Color.WHITE);
    }
    return prepareRenderer;
   }
  };
4、仿MSN弹出面板

5、Spinner循环

   原理:重载了getNextValue和getPreviousValue两个方法
  final SpinnerNumberModel model = new SpinnerNumberModel();
  model.setMaximum(new Integer(5));
  model.setMinimum(new Integer(0));
  final JSpinner spinner = new JSpinner() {
   public Object getNextValue() {
    if (this.getValue().toString().equals(model.getMaximum().toString())) {
     return model.getMinimum();
    }
    return super.getNextValue();
   }

   public Object getPreviousValue() {
    if (this.getValue().toString().equals(model.getMinimum().toString())) {
     return model.getMaximum();
    }
    return super.getPreviousValue();
   }
  };
  spinner.setModel(model);

6、2D去锯齿
只是因为名称太长...
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING , RenderingHints.VALUE_ANTIALIAS_ON);

7、修改全局文字

public static void setUIFont (javax.swing.plaf.FontUIResource f){

   java.util.Enumeration keys = UIManager.getDefaults().keys();

while (keys.hasMoreElements()) {

Object key = keys.nextElement();

Object value = UIManager.get (key);

if (value instanceof javax.swing.plaf.FontUIResource)

UIManager.put (key, f);

}

}

 

最后修改:10.06.24
