Java Swing第二个JFrame布局是否填满了空间?
我一直在学习手写Swing,并一直在使用Sun Doc教程。我使用的是GridLayout,在我第一次使用它时,所有按钮都填满了可用空间。在我的第二次尝试中,我已经实现了第二个网格来在顶部保存一些控件。我相信这是一件非常简单的事情,但在阅读和玩了很久之后,我无法像第一次尝试那样让第二个下窗格充满按钮。请帮忙Java Swing第二个JFrame布局是否填满了空间?,java,swing,Java,Swing,我一直在学习手写Swing,并一直在使用Sun Doc教程。我使用的是GridLayout,在我第一次使用它时,所有按钮都填满了可用空间。在我的第二次尝试中,我已经实现了第二个网格来在顶部保存一些控件。我相信这是一件非常简单的事情,但在阅读和玩了很久之后,我无法像第一次尝试那样让第二个下窗格充满按钮。请帮忙 package layout; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class

不读你的问题,只看代码,运行这个代码你必须改变
GridBagLayoutDemo frame = new GridBagLayoutDemo("GridLayoutDemo");
到
编辑
1) 通过调用方法pack();正确设置JComponents的大小
2) 然后正确设置为可见(true)
但是
然后编码setSize()
在南部地区创建的间隙
接近正确的应该是
private static void createAndShowGUI() {
Game frame = new Game("Game");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.addComponentsToPane(frame.getContentPane());
frame.setMinimumSize(new Dimension(400, 400));
frame.pack();
frame.setVisible(true);

我想我发现了未来读者的问题,按钮需要声明为:
JButton btnOne1 = new JButton("btnOne1");
btnOne1.setPreferredSize(new Dimension(100, 100));
然后
mainGameWindow.add(btnOne1);
这会让他们填满他们所在的窗口 我想我发现了未来读者的问题,按钮需要声明为:
