我有几种方法可以在JButton
中创建自己的组件JLabel
或JPanel
。然后我有一个单独的方法,将所有这些JPanels
添加到JFrame
。我还在JPanels上使用gridx
和gridy
来定位他们我想要的方式。这是:看起来在左边,然后在标题的右上方和下面的2X2
表中退出,重启,取件和你好。但是,我当前运行的代码显示一个奇怪的,随机的布局。
看起来是在左边,但是在右边是退出,一个空格,重新启动然后你好所有垂直。没有看到皮卡和头衔。我不知道为什么会这样。
请参阅下面的代码。:
public class GUI extends JPanel
{
/**
* Creation of variables used throughout the GUI Class.
*/
//JPanel panel = new JPanel(new GridBagLayout());
private static final long serialVersionUID = 1L;
public static void main(String[] args)
{
GUI g = new GUI();
g.create();
}
private void create()
{
JFrame screen = new JFrame("Dungeon of Doom");
screen.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
screen.setLayout(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
//set size to full screen.
screen.setExtendedState(Frame.MAXIMIZED_BOTH);
//Add all JPanes to screen
screen.add(lookReply(), c);
c.gridy = 0;
c.gridx = 0;
screen.add(title(), c);
c.gridy = 0;
c.gridx = 1;
c.gridwidth = 2;
screen.add(quit(), c);
c.gridy = 1;
c.gridx = 1;
screen.add(restart(), c);
c.gridy = 1;
c.gridx = 2;
screen.add(pickup(), c);
c.gridy = 2;
c.gridx = 1;
screen.add(hello(), c);
c.gridy = 2;
c.gridx = 2;
screen.setVisible(true);
}
其中一种方法(退出)
private JPanel quit()
{
JPanel quitPanel = new JPanel(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
JButton quit = new JButton("QUIT");
quitPanel.add(quit, c);
return quitPanel;
}
除了标题是JLabel
之外,所有其他方法几乎相同,并且表格迭代以在其5x5
内创建JLabel
JPanel
表。任何帮助表示赞赏!
答案 0 :(得分:1)
我找到了这样做的原因。 如代码所示,我在设置布局之前添加了组件。
screen.add(lookReply(), c);
c.gridy = 0;
c.gridx = 0;
然而它应该是
c.gridy = 0;
c.gridx = 0;
screen.add(lookReply(), c);
