java AWT

AWT： Java图形界面编程

组件 compontent

元素

1. Button
2. TextArea
3. Label

容器

window

Frame

在主函数中直接定义一个Frame对象，并设置相应属性，运行时就可以显现Frame组件

​ 在Frame中可以添加面板和其他组件用add()方法

java Frame frame = new Frame(); //设置边界 bounds(x,y,w,h) 分别对应x坐标y坐标，宽和长 frame.setBounds(100, 100, 200, 200); //设置背景颜色 color(r,g,b)分别对应red,green,blue frame.setBackground(new Color(10,20,100)); //设置是否可以改变边框大小 frame.setResizable(true); //设置布局 ：有FlowLayout(),BorderLayout(),GridLayout()等布局 frame.setLayout(new FlowLayout()); //在frame中添加面板 frame.add(new Panel()) //添加关闭窗口监听 frame.addWindowListener(new WindowAdapter(){ public void windowClosing(WindowEvent e){ System.exit(0); } }); //设置可视化 frame.setVisible(true);

Dialog

对话框，要和Frame连用

Dialog dialog = new Dialog(frame);

Panel

一般在panel中添加图形和按钮等组件，然后把panel加到frame中，单独无法使用

//在panel中画图形
panel.paint(new Graphics(){

			@Override
			public void clearRect(int arg0, int arg1, int arg2, int arg3) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void clipRect(int arg0, int arg1, int arg2, int arg3) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void copyArea(int arg0, int arg1, int arg2, int arg3,
					int arg4, int arg5) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public Graphics create() {
				// TODO Auto-generated method stub
				return null;
			}

			@Override
			public void dispose() {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void drawArc(int arg0, int arg1, int arg2, int arg3,
					int arg4, int arg5) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public boolean drawImage(Image arg0, int arg1, int arg2,
					ImageObserver arg3) {
				// TODO Auto-generated method stub
				return false;
			}


			@Override
			public void drawLine(int arg0, int arg1, int arg2, int arg3) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void drawOval(int arg0, int arg1, int arg2, int arg3) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void drawPolygon(int[] arg0, int[] arg1, int arg2) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void drawPolyline(int[] arg0, int[] arg1, int arg2) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void drawRoundRect(int arg0, int arg1, int arg2, int arg3,
					int arg4, int arg5) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void drawString(String arg0, int arg1, int arg2) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void drawString(AttributedCharacterIterator arg0, int arg1,
					int arg2) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void fillArc(int arg0, int arg1, int arg2, int arg3,
					int arg4, int arg5) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void fillOval(int arg0, int arg1, int arg2, int arg3) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void fillPolygon(int[] arg0, int[] arg1, int arg2) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void setColor(Color arg0) {
				// TODO Auto-generated method stub
				
			}

		});
		
//或者添加组件
panel.add(new Button());
