GUI 编程【二】
——GridLayout , BorderLayout,将面板作为容器使用:
GridLayout:
package java19; import java.awt.Container; import java.awt.GridLayout; import javax.swing.JButton; import javax.swing.JFrame; public class ShowGridLayout extends JFrame { public ShowGridLayout() { Container container=getContentPane(); //定义容器 container.setLayout(new GridLayout(4,3,10,20)); //等价于: //GridLayout layout=new GridLayout(FlowLayout.LEFT,10,20); //container.setLayout(layout); //布局方式 for(int i=1;i<=10;i++) { container.add(new JButton("Component"+i)); } } public static void main(String[] args) { ShowGridLayout frame=new ShowGridLayout(); frame.setTitle("show FlowLayout"); frame.setSize(200,200); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }
效果图
BorderLayout:
package java19; import java.awt.BorderLayout; import java.awt.Container; import java.awt.GridLayout; import javax.swing.JButton; import javax.swing.JFrame; public class ShowBorderLayout extends JFrame { public ShowBorderLayout() { Container container=getContentPane(); //定义容器 ,BorderLayout(x,y),x,y分别为水平和垂直间距 container.setLayout(new BorderLayout(5,10)); //等价于: ; //BorderLayout layout=new BorderLayout(5,10); //container.setLayout(layout); //布局方式 container.add(new JButton("East"),BorderLayout.EAST); container.add(new JButton("South"),BorderLayout.SOUTH); container.add(new JButton("West"),BorderLayout.WEST); container.add(new JButton("North"),BorderLayout.NORTH); container.add(new JButton("Center"),BorderLayout.CENTER); } public static void main(String[] args) { ShowBorderLayout frame=new ShowBorderLayout(); frame.setTitle("show FlowLayout"); frame.setSize(200,200); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }
效果
将面板作为容器使用:
package java19; import java.awt.BorderLayout; import java.awt.Button; import java.awt.Container; import java.awt.GridLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JTextField; public class TestPanels extends JFrame { public TestPanels() { //创建容器 Container container=getContentPane(); container.setLayout(new BorderLayout()); //创建面板p1 JPanel p1=new JPanel(); p1.setLayout(new GridLayout(4,3)); //对p1面板添加数据 for(int i=1;i<9;i++) { p1.add(new JButton(" "+i)); } p1.add(new JButton(" "+0)); p1.add(new JButton("start")); p1.add(new JButton("stop")); //创建面板p2 JPanel p2=new JPanel(); p2.setLayout(new BorderLayout()); p2.add(new JTextField("time to be display here"),BorderLayout.NORTH); p2.add(p1,BorderLayout.CENTER); //添加到容器 container.add(p2,BorderLayout.EAST); container.add(new Button("Food to be place here"),BorderLayout.CENTER); } public static void main(String[] args) { TestPanels frame=new TestPanels(); frame.setTitle("the front view of a microwave oven"); frame.setSize(200,200); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }
效果:
