自定义摆动布局
Custom Swing layout
我正在创建游戏并按照我想要的方式设置框架,我需要了解如何创建服装布局。我已经尝试创建多个具有不同布局的面板,例如 Flow 和 Border,并在主面板上添加面板,但我仍然没有得到想要的结果。我想要的在附图中显示。请告诉我是否有任何代码段有帮助。
问题:
1. 是否可以得到这样的布局? (我希望它得到修复。)
- 在 "button" 下面是您在图片中看到的 JLabel。我希望它的文本从左边开始,沿着列向下,从中间开始,然后到右边的列。这可能吗?
我在评论中写的内容略有不同,因为 BoxLayout
有点东西,我从不使用,因为我不擅长:-)
虽然我克服了我的这个缺点,但我的这个缺点是需要2 JPanel
s,JTextField
和JButton
各一个,其余的是一样的,因为本例所示:
import java.awt.*;
import javax.swing.*;
public class LayoutExample {
private static final int GAP = 5;
private static final int TOTAL_LABELS = 18;
private JTextField tField;
private JButton button;
private JLabel[] labels;
private void displayGUI () {
JFrame frame = new JFrame ( "Layout Example" );
frame.setDefaultCloseOperation ( JFrame.DISPOSE_ON_CLOSE );
JPanel contentPane = getPanel ();
contentPane.setLayout ( new BorderLayout ( GAP, GAP ) );
JPanel headerPanel = getPanel ();
headerPanel.setLayout ( new GridLayout ( 0, 1, GAP, GAP ) );
JPanel textFieldPanel = getPanel ();
tField = new JTextField ( 10 );
textFieldPanel.add ( tField );
JPanel buttonPanel = getPanel ();
button = new JButton ( "Button" );
buttonPanel.add ( button );
headerPanel.add ( textFieldPanel );
headerPanel.add ( buttonPanel );
contentPane.add (headerPanel, BorderLayout.PAGE_START );
JPanel centerPanel = getPanel ();
centerPanel.setLayout ( new GridLayout ( 0, 3, GAP, GAP ) );
labels = new JLabel [ TOTAL_LABELS ];
for ( int i = 0; i < labels.length; ++i ) {
labels [ i ] = new JLabel ( String.valueOf ( i ), JLabel.CENTER );
centerPanel.add ( labels [ i ] );
}
contentPane.add ( centerPanel, BorderLayout.CENTER );
frame.setContentPane ( contentPane );
frame.pack ();
frame.setLocationByPlatform ( true );
frame.setVisible ( true );
}
private JPanel getPanel () {
JPanel panel = new JPanel ();
panel.setOpaque ( true );
panel.setBorder ( BorderFactory.createEmptyBorder ( GAP, GAP, GAP, GAP ) );
return panel;
}
public static void main ( String[] args ) {
Runnable runnable = new Runnable () {
@Override
public void run () {
new LayoutExample ().displayGUI ();
}
};
EventQueue.invokeLater ( runnable );
}
}
