如何设置jlabel的修复大小？ [英] How to set fix size of jlabel?
问题描述
我正在尝试创建一个java桌面应用程序，我使用多个 JLabel 我想设置修复高度和宽度 JLabel 。我怎样才能做到这一点？
I am trying to make a java desktop application where I am using multiple JLabel I want to set fix height and width of JLabel. How can I achieve this?
这是我的代码
public class Second extends JFrame
{
JPanel panel1,panel2;
JLabel label=new JLabel();
ArrayList<JLabel> 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("<html>Case Item CaseNum<br><font color=yellow>Party1<br>Party2</font></html>");
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/ code>然后 JLabel 的大小减少但我想减少或删除 JLabel 中的任何文本但是Jlabel的大小不应该减少它应该修复
When I reduce text size or text from JLabel then size of JLabel reduced but I want that when i reduced or remove any text from JLabel but size of Jlabel should not reduced it should fix
我怎么能得到这个？

推荐答案
您可以通过设置最小，首选和最大尺寸来设置固定大小：
You can set a fixed the size by setting the minimum, preferred and maximum size:
setMinimumSize(width, height);
setPreferredSize(width, height);
setMaximumSize(width, height);
由于 MadProgrammer 中避免使用setpreferredmaximumminimumsize-methods-in-java-swi>链接，你需要覆盖这些方法，而不是从外部使用它们，基于关于链接。
As the Link from MadProgrammer, you need to override these methods, not using them from outside, based on the reasons mentioned in this link.
