How to set padding at JLabel
提问by bircastri
I want to display a Multiline JLabel into JPanel. So I have this code but I'm not able to show the multiline JLabel.
我想在 JPanel 中显示多行 JLabel。所以我有这个代码，但我无法显示多行 JLabel。
public class NotificationFrame extends JFrame{
public NotificationFrame(){
JPanel panelBody = new JPanel();
panelBody.setBackground(Color.white);
GridBagConstraints GBC2 = new GridBagConstraints();
Container CR2 = new Container();
GridBagLayout GBL2 = new GridBagLayout();
CR2.setLayout(GBL2);
panelBody.add(CR2);
GBC2 = new GridBagConstraints();
CR2.add(labelTesto);
GBC2.gridx=0;
GBC2.gridy=0;
GBC2.insets.left = 10;
GBC2.insets.top=0;
GBL2.setConstraints(labelTesto,GBC2);
panelBody.setLayout(new FlowLayout(FlowLayout.CENTER));
add(panelBody,BorderLayout.CENTER);
}
}
If I change the last line of code in
如果我更改最后一行代码
add(labelTest,BorderLayout.CENTER);
I can show that I want. But it is not correct because I want to set a padding on JLabel
我可以表现出我想要的。但这不正确，因为我想在 JLabel 上设置填充

I have use this code now:
我现在已经使用了这个代码：
JPanel panelBody = new JPanel();
panelBody.setBackground(Color.white);
SpringLayout layout = new SpringLayout();
panelBody.setLayout(layout);
panelBody.add(labelTesto);
layout.putConstraint(SpringLayout.NORTH, labelTesto, 15, SpringLayout.NORTH, panelBody);
add(panelBody,BorderLayout.CENTER);
This is the layout:
这是布局：
This is the all test that I should see: "Il 31 Dicembre scadrà l'assistenza, ricorda di rinnovare l'assistenza per ricevere sempre assistenza ed aggiornamenti."
这是我应该看到的所有测试：“Il 31 Dicembre scadrà l'assistenza, ricorda di rinnovare l'assistenza per Ricevere semperassistenza ed aggiornamenti。”

Multiline it's not padding. For achieve multiline text in JLabel or JButton you need to use HTML.
多行它不是填充。要在 JLabel 或 JButton 中实现多行文本，您需要使用 HTML。
To wrap text (or multiline):
换行文本（或多行）：
btn.setText("<html><p>Il 31 Dicembre scadrà l'assistenza, ricorda di rinnovare l'assistenza per ricevere sempre assistenza ed aggiornamenti</p></html>");
label.setText("<html>Date:<br></html>"+getDateFromSomeWhere);
To set padding:
设置填充：
label.setBorder(new EmptyBorder(0,10,0,0));//top,left,bottom,right
