GUI设计基础入门

流式布局

package yang;

import java.awt.*;

public class Button1 {
    public static void main(String[] args) {
        Frame frame = new Frame();
        Button button1 = new Button("Button1");
        Button button2 = new Button("Button2");
        Button button3 = new Button("Button3");
		
        //FlowLayout.RIGHT(右)(中)(左)
        frame.setLayout(new FlowLayout(FlowLayout.RIGHT));

        frame.setSize(200,200);

        frame.add(button1);
        frame.add(button2);
        frame.add(button3);

        frame.setVisible(true);
        //可见性


    }
}

东西南北中

package yang;

import java.awt.*;

public class Button2 {
    public static void main(String[] args) {
        Frame frame = new Frame("Test BorderLayout");

        Button east = new Button("east");
        Button west = new Button("west");
        Button north = new Button("north");
        Button south = new Button("south");
        Button center = new Button("center");

        frame.add(east,BorderLayout.EAST);
        frame.add(west,BorderLayout.WEST);
        frame.add(north,BorderLayout.NORTH);
        frame.add(south,BorderLayout.SOUTH);
        frame.add(center,BorderLayout.CENTER);

        frame.setSize(600,600);

        frame.setResizable(false);

        frame.setVisible(true);
    }
}

表格布局

package yang;

import java.awt.*;

public class Button3 {
    public static void main(String[] args) {
        Frame frame = new Frame();

        Button button1 = new Button("button1");
        Button button2 = new Button("button2");
        Button button3 = new Button("button3");
        Button button4 = new Button("button4");
        Button button5 = new Button("button5");
        Button button6 = new Button("button6");

        //GridLayout(3(行),2(列),10(左右距离),10(上下距离))
        frame.setLayout(new GridLayout(3,2,10,10));

        frame.add(button1);
        frame.add(button2);
        frame.add(button3);
        frame.add(button4);
        frame.add(button5);
        frame.add(button6);


        frame.pack();
        frame.setVisible(true);
    }
}

示例：混合布局

package yang;

import java.awt.*;

public class ButtonZero {
    public static void main(String[] args) {
        Frame frame = new Frame();

        frame.setSize(400,300);
        frame.setLocation(300,400);
        frame.setBackground(Color.BLACK);
        frame.setVisible(true);

        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);
        p1.add(new Button("West-1"),BorderLayout.WEST);

        p2.add(new Button("1"));
        p2.add(new Button("2"));

        p1.add(p2,BorderLayout.CENTER);

        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("Button"+1));
        }
        p3.add(p4,BorderLayout.CENTER);

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