use*_*824 12 java swing jlabel null-layout-manager
我正在尝试创建一个java桌面应用程序,我正在使用多个JLabel我想设置修复高度和宽度JLabel.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<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;
}
当我减少文本大小或文本JLabel 从那时JLabel减少的大小但我希望当我减少或删除任何文本,JLabel但Jlabel的大小不应该减少它应该修复
我怎么能得到这个？

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);
当链接从MadProgrammer,你需要重写这些方法,不使用它们来自外部的基础上,在此提到的原因链接.
如果这个方法不起作用
setMinimumSize(width, height);
setPreferredSize(width, height);
setMaximumSize(width, height);
然后使用它
setMinimumSize(new Dimension(width, height));
setPreferredSize(new Dimension(width, height));
setMaximumSize(new Dimension(width, height));
