二JPanels在JFrame中，另外一个下 [英] Two JPanels in JFrame , One under other
问题描述
我有两个小组在我的框架，我想将它们设置一个其他的根据，这首先应该有大小像9月10日*屏幕边框，而本次的1/10。
我试过用网格布局（2行一列），但我不能将它们设置特定大小。
我应该怎么办呢？
好吧，也许我会写一些我的code：
我写的游戏 - 吃豆子，并在第一盘有一整场比赛，在这第二个我想显示播放信息（如成绩，姓名等），这首先我想在80％设定屏幕上，并且第二对20％。
更重要的是我的框架应该是调整大小和所有在里面，SA我必须改变面板的大小（这保持80％〜20％）时，帧大小是变化的。所以，我写这个的initComponents（）。

GridLayout的是错误的布局，如果你想不同尺寸的组件。由于的javadoc 规定：
的容器被分成相等大小的矩形，和一个
组件放置在每个矩形如果你只得到了
的JPanelS，你可能要考虑一个调整JSplitPane- 看到的的javadoc 或的教程。编辑：根据您的编辑/ code，一个真正的JSplitPane貌似解决您的问题。然后，您可以创建后，使用设定的分隔位置
setDividerLocation（双）- 看到<一个href=\"http://docs.oracle.com/javase/1.4.2/docs/api/javax/swing/JSplitPane.html#setDividerLocation%28double%29\"相对=nofollow>的javadoc - 例如分裂的JSplitPane =新JSplitPane（JSplitPane.VERTICAL）;
split.setTopComponent（topPanel）;
split.setBottomComponent（bottomPanel）;
split.setDividerLocation（0.8）;另外，因为它是相当困难不知道你的意图的GUI建议的布局，就应该考虑采取一看的视觉指南来布局。
I've got two panels in my frame, and I would like to set them one under other, and this first should have size like 9/10*screen frame, and this second 1/10.
I've tried with GridLayout (2 rows and one column) but I can't set them specific size.
How should I do that?
ok maybe I will write some my code:
I am writing game - pacman, and in the first panel there is a whole game, and in this second I would like to display player info(like score, name etc.) This first I would like to set on 80% screen, and second on 20%.
What is more my frame should be resizeable and all in it, sa I have to change size of Panels(keeping this 80% to 20%) when size of frame is changing. SO that I wrote this InitComponents().
package pacman; import java.awt.BorderLayout; import java.awt.Dimension; import java.awt.EventQueue; import java.awt.GridLayout; import java.awt.Toolkit; import javax.imageio.ImageIO; import javax.swing.JFrame; import java.awt.Image; import java.awt.event.ComponentAdapter; import java.awt.event.ComponentEvent; public class Pacman extends JFrame implements items { Image image; public Pacman() { initComponents(); try { image = ImageIO.read( Pac.class.getResourceAsStream("/img/Pac02.gif")); } catch (Exception e) { System.out.println("Blad prz otwieraniu " + e); System.exit(0); } int screen_width = Toolkit.getDefaultToolkit().getScreenSize().width; int screen_height = Toolkit.getDefaultToolkit().getScreenSize().height; this.setLocation(screen_width/3, screen_height/3); this.setLayout(new BorderLayout()); this.getContentPane().add(panel, BorderLayout.CENTER); this.getContentPane().add(panel2, BorderLayout.PAGE_END); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setIconImage(image); setTitle("..::Pacman::.."); setDefaultCloseOperation(EXIT_ON_CLOSE); this.setPreferredSize(new Dimension(416,438)); this.pack(); setLocationRelativeTo(null); setVisible(true); } private void initComponents() { setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.addComponentListener(new ComponentAdapter() { @Override public void componentResized(ComponentEvent e) { int width = e.getComponent().getSize().width; int height = e.getComponent().getSize().height; panel.setSize(width, height*8/10) ; panel2.setSize(width, height*2/10); } }); } public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { @Override public void run() { new Pacman(); } }); } }
解决方案GridLayout is the wrong layout if you want different sized components. As the javadoc states:
The container is divided into equal-sized rectangles, and one component is placed in each rectangle.
If you've only got
JPanels, you might want to consider aJSplitPane- see javadoc or tutorial.EDIT: Based on your edit/code, a JSplitPane really looks like the solution to your problem. You can then set the divider location after creation using
setDividerLocation(double)- see the javadoc - e.g.JSplitPane split = new JSplitPane(JSplitPane.VERTICAL); split.setTopComponent(topPanel); split.setBottomComponent(bottomPanel); split.setDividerLocation(0.8);Alternatively, since it's quite hard to suggest a layout without knowing your intentions for the GUI, you should consider taking a look at the Visual Guide to layouts.
