java-GUI布局小练习

java GUI布局小练习

实现如图布局

思路

采用面板嵌套方式, 先分成上下俩个面板, 整体的上下部分(BorderLayout)划分为一个大面板,中间嵌套小面板,小面板可以采用GridLayout布局

import java.awt.*;
import java.util.GregorianCalendar;

public class exercise {
    public static void main(String[] args) {
        Frame frame = new Frame();
        frame.setVisible(true);
        frame.setBackground(Color.red);
        frame.setSize(400, 400);
        frame.setLayout(new GridLayout(2,1));

        Panel p1 = new Panel(new BorderLayout());
        Panel p2 = new Panel(new GridLayout(2, 1));
        Panel p3 = new Panel(new BorderLayout());
        Panel p4 = new Panel(new GridLayout(2, 2));

        p1.add(new Button("east-1"), BorderLayout.EAST);
        p2.add(new Button("up-1"));
        p2.add(new Button("down-1"));
        p1.add(p2, BorderLayout.CENTER);
        p1.add(new Button("west-1"), BorderLayout.WEST);

        p3.add(new Button("east-2"), BorderLayout.EAST);
        p3.add(new Button("west-2"), BorderLayout.WEST);
        for (int i = 0; i < 4; i++) {
            p4.add(new Button("bt" + i));
        }

        p3.add(p4, BorderLayout.CENTER);

        frame.add(p1);
        frame.add(p3);

    }
}

布局管理器小结

1. 流式 FlowLayout
2. 东西南北中 BorderLayout
3. 表格 GridLayout
