Java开发GUI之BorderLayout边界布局

	static void BorderLayoutTest(){
		Frame frame = new Frame("Label");
		BorderLayout layout = new BorderLayout(10,15);
		Panel pannel = new Panel(layout);
		pannel.add(BorderLayout.NORTH, new Button("北方"));
		pannel.add(BorderLayout.SOUTH, new Button("南方"));
		pannel.add(BorderLayout.EAST, new Button("东方"));
		pannel.add(BorderLayout.WEST, new Button("西方"));
		pannel.add(BorderLayout.CENTER, new Button("中心"));
		frame.add(pannel);
		frame.pack();
		frame.show();

//常量 指定布局在北方位置
public static final String NORTH  = "North";
//常量 指定布局在南方位置
public static final String SOUTH  = "South";
//常量 指定布局在东方位置
public static final String EAST   = "East";
//常量 指定布局在西方位置
public static final String WEST   = "West";
//常量 指定布局在中心位置
public static final String CENTER = "Center";
//初始化方法 默认无间距
public BorderLayout();
//初始化方法 hgap设置水平间距 vgap设置垂直间距
public BorderLayout(int hgap, int vgap);
//获取水平间距
public int getHgap();
//设置水平间距
public void setHgap(int hgap);
//获取垂直间距
public int getVgap();
//设置垂直间距
public void setVgap(int vgap);
