Is there a way to add a JLabel to JtextArea? cause I try the add
but it didnt work and set it to visible true, is it allowed to add a JLabel inside the JTextArea? through append?
Here is my current code that didnt work
jta = new JTextArea();
jta.setEditable(false);
jta.setLineWrap(true);
jta.setWrapStyleWord(true);
jta.setFont(new Font("calibri", Font.PLAIN,16));
jlArray = new JLabel("radsjhkaljk sadf");
jta.add(jlArray);
jta.setVisible(true);
jspTextField = new JScrollPane(jta);
Can I append the JLabel inside the JTextArea each time a message is added?
JTextArea
is not the appropriate swing
component to insert JLabels
or any other components within it. You can use JTextPane
for this purpose. For example , consider the code given below:
import javax.swing.*;
import javax.swing.text.*;
import javax.swing.border.*;
import java.awt.event.*;
import java.awt.*;
class JLabelToTextPane extends JFrame implements ActionListener
{
JTextField tf;
JTextPane tp ;
JButton click;
StyledDocument doc;
SimpleAttributeSet attr;
public void createAndShowGUI()
{
setTitle("Add JLabel to JTextPane");
tf = new JTextField(10);
tp = new JTextPane();
click = new JButton("Click");
doc = tp.getStyledDocument();
attr = new SimpleAttributeSet();
JScrollPane pane = new JScrollPane(tp);
JPanel nPanel = new JPanel();
nPanel.add(tf);nPanel.add(click);
tf.addActionListener(this);
click.addActionListener(this);
Container c = getContentPane();
c.add(nPanel,BorderLayout.NORTH);
c.add(pane);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(300,200);setLocationRelativeTo(null);setVisible(true);
}
@Override
public void actionPerformed(ActionEvent evt)
{
String text = tf.getText();
if (text!=null && !"null".equals(text) && !"".equals(text.trim()))
{
JLabel label = new JLabel(text);
label.setOpaque(true);
label.setBackground(Color.gray);
label.setBorder(BorderFactory.createLineBorder(Color.black,1));
tp.setCaretPosition(tp.getDocument().getLength());
tp.insertComponent(label);
label.addMouseListener(new MouseAdapter()
{
public void mouseClicked(MouseEvent evt)
{
String text = ((JLabel)evt.getSource()).getText();
JOptionPane.showMessageDialog(JLabelToTextPane.this,"Hi, My text is "+text,"Information",JOptionPane.INFORMATION_MESSAGE);
}
});
try
{
doc.insertString(doc.getLength(), " ", attr );
}
catch (BadLocationException ex)
{
ex.printStackTrace();
}
}
}
public static void main(String[] args)
{
SwingUtilities.invokeLater( new Runnable()
{
@Override
public void run()
{
JLabelToTextPane lta = new JLabelToTextPane();
lta.createAndShowGUI();
}
});
}
}
