如何设置jlabel的修复大小？
我正在尝试创建一个java桌面应用程序，我正在使用多个JLabel我想设置JLabel修复高度和宽度。 我怎样才能做到这一点？
这是我的代码
public class Second extends JFrame { JPanel panel1,panel2; JLabel label=new JLabel(); ArrayList lbllist = new ArrayList(); public Second() { super("Simple Timer"); { getContentPane().setBackground(new java.awt.Color(255,255,255)); } this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); Container c = getContentPane(); c.setLayout( new FlowLayout()); setUndecorated(true); Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize(); setBounds(0,0,screenSize.width, screenSize.height); panel2=new JPanel(); panel2.setBounds(360, 180, 360, 1020); panel2.setBackground(new java.awt.Color(255,153,51)); c.add(panel2); JPanel panel3 = createPanel(); panel1.setLayout(new GridBagLayout()); panel1.add(panel3); JPanel panel4 = createPanel(); panel2.setLayout(new GridBagLayout()); // jPanel2.setLayout(null); panel2.add(panel4); setLayout(null); } private JPanel createPanel() { JPanel panel = new JPanel(new GridLayout(0, 1, 10, 5)); EmptyBorder panelBorder = new EmptyBorder(10, 5, 10, 10); panel.setBorder(panelBorder); panel.setBackground(new java.awt.Color(255, 153, 51)); panel.setOpaque(true); EmptyBorder border1 = new EmptyBorder(5, 20, 15, 18); Border border = BorderFactory.createLineBorder(Color.BLUE, 2); for (int i = 0; i <11; i++) { label = new JLabel("Case Item CaseNum
Party1
Party2"); label.setFont(new java.awt.Font("Times New Roman", 1, 18)); label.setBorder(border); label.setSize(300, 100); label.setBorder(border1); Dimension d = label.getPreferredSize(); label.setBackground(Color.GRAY); label.setForeground(new java.awt.Color(255, 255,255 )); label.setOpaque(true); lbllist.add(label); panel.add(label); } return panel; }
当我从JLabel减少文本大小或文本时， JLabel大小减少但我希望当我减少或删除JLabel中的任何文本但Jlabel的大小不应该减少它应该修复
我怎么能得到这个？
提前致谢
您可以通过设置最小，首选和最大大小来设置固定大小：
setMinimumSize(width, height); setPreferredSize(width, height); setMaximumSize(width, height);
作为MadProgrammer的链接 ，您需要根据此链接中提到的原因覆盖这些方法，而不是从外部使用它们。
如果这种方法不起作用
setMinimumSize(width, height); setPreferedSize(width, height); setMaximumSize(width, height);
然后使用它
setMinimumSize(new Dimension(width, height)); setPreferedSize(new Dimension(width, height)); setMaximumSize(new Dimension(width, height));
一个简单的解决方法（不覆盖现有的类）是;
-
专门为组件创建JPanel
-
设置JPanel的大小
-
将组件放在JPanel中
-
将JPanel放在最初放置组件的位置
例如
JPanel mainPanel = new JPanel(); //Assume this is the panel you are placing things into. JLabel nameLabel = new JLabel("Name:"); JPanel nameLabelPanel = new JPanel(); nameLabelPanel.setPreferredSize(new Dimension(100, 25)); JPanel.add(nameLabel); mainPanel.add(nameLabelPanel);
使用JLabel.setPreferredSize(width, height); jpanel没有布局，尝试Jpanel pane = new JPanel（new FlowLayout（））;
