2. 设置 GridLayout 接下来,我们将为 JFrame 设置 GridLayout,以便可以更有组织地添加组件。 importjava.awt.*;// 引入AWT包publicclassGridLayoutExample{publicstaticvoidmain(String[]args){// 创建窗口JFrameframe=newJFrame("GridLayout Example");frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);frame....

以下是设置组件比例的示例代码: import javax.swing.*; import java.awt.*; public class GridLayoutExample { public static void main(String[] args) { JFrame frame = new JFrame("GridLayout Example"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel panel = new JPanel(); GridLayou...
下面是一个示例代码,演示如何使用GridLayout将多个按钮按照3行2列的网格布局放置在一个JFrame中: import javax.swing.JButton; import javax.swing.JFrame; import java.awt.GridLayout; public class GridLayoutExample { public static void main(String[] args) { JFrame frame = new JFrame("GridLayout Exam...

public classGridLayoutextendsObjectimplementsLayoutManager,Serializable TheGridLayoutclass is a layout manager that lays out a container's components in a rectangular grid. The container is divided into equal-sized rectangles, and one component is placed in each rectangle. For example, the following is...

For example, the following is an applet that lays out six buttons into three rows and two columns: import java.awt.*; import java.applet.Applet; public class ButtonGrid extends Applet { public void init() { setLayout(new GridLayout(3,2)); add(new Button("1")); add(new Button("2"...
