frame.setVisible(true)
// frame.setLocation(x, y);
// frame.setSize(w,h);
frame.setBounds(x,y,w,h);
frame.setBackground(Color color);

布局

• 默认

• 流式布局

Button leftButton = new Button("Left");
Button rightButton = new Button("Right");

myFrame1.setLayout(new FlowLayout(FlowLayout.LEFT));
myFrame1.add(leftButton);
myFrame1.add(rightButton);
// 默认: CENTER
// frame.setLayout(new FlowLayout(FlowLayout.CENTER));
// frame.setLayout(new FlowLayout(FlowLayout.RIGHT));

• 东西南北中

Button installButton = new Button("Install");
Button exitButton = new Button("Exit");

myFrame2.setLayout(new BorderLayout());

myFrame2.add(exitButton, BorderLayout.WEST);
myFrame2.add(installButton, BorderLayout.EAST);

• 表格布局

Panel

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");


myFrame3.setLayout(new GridLayout(3,2));
myFrame3.add(button1);
myFrame3.add(button2);
myFrame3.add(button3);
myFrame3.add(button4);
myFrame3.add(button5);
myFrame3.add(button6);
