In there, I am also trying to set the font size to 25, but as you can see, it is not working. "textPane.setFont()" also didn't work. How can I set the font size correctly? Please help..
Sure, you can create a font object and use it to set the font of your text pane.
Instantiate it like this:
Font f = new Font(Font.SANS_SERIF, 3, 5);
Maybe this code will help you, about Highlighter and StyledDocument, rest is described in the tutorial about JTextPane / EditorPane

Is there a way to obtain the row index within an HTML table defined in a JEditorPane? I tried viewToModel method but this isn't what I was expecting.
pane.addMouseListener(new MouseListener(){
#Override
public void mouseClicked(MouseEvent e) {
System.out.println( pane.viewToModel(e.getPoint()) );
}
...
Easy/lazy answer: of course you cannot. Even in a pure html page, you need some javascript to achive this.
JEditorPane can't handle javascript (i think, maybe i'm wrong), so no chance.
Now, you can use a different approach:
Change a field (or create a new one) with a link.
The link will have as url somenthing like #rowXXX, where XXX is the number of the row.
Some field
Add a HyperlinkListener to the jEditorPane:
editor.addHyperlinkListener(new HyperlinkListener() {
#Override
public void hyperlinkUpdate(HyperlinkEvent e) {
if(e.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
try {
String rowcode = e.getDescription();
int row = Integer.parseInt(rowcode.replace("#row",""));
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
}
});
Now in row you should have the number of the row.

I need to write a program that I will create a runnable jar and distribute. The functions should be like below:
when double click the jar, it will open a window.
it will ask the path where to save the image files.
it will then ask whether to add any prefix / suffix / both on every image along with timestamp for unique name.
it will also ask what image format to use.
the app can be minimized and closed
it will take a full screenshot whenever PrintScreen is pressed and save.
Please provide a programme that is complete. I have gathered pieces but could not put them in one. Here is my code :-
import java.awt.*;
import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.Transferable;

textField1.setText("");
}
});
textField1.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
location = textField1.getText();
System.out.println(location);
}
});
f.getContentPane().add(textField1);
final JTextField textField2 = new JTextField("Enter Prefix or Leave Empty");
textField2.addMouseListener(new MouseAdapter(){
#Override

textField2.setText("");
}
});
textField2.addActionListener(new ActionListener() {

}
}
The first try catch block can open a window, take image format, prefix and storage location. The second try catch block alone can take screen shot when run not when printscreen key is pressed but with the first try catch it does not print anything. So, what to do to take the screenshot when printscreen key is pressed ?
I have approached the solution in a little bit another way.
As people always works with mouse while on online meeting, I removed the clause of PrintScreen button from keyboard and instead the attendees can click on swing window button to capture screen.
My solution as follows:

textField1.addMouseListener(new MouseAdapter(){

});
f.getContentPane().add(textField1);
final JTextField textField2 = new JTextField("Enter MeetingID");
textField2.addMouseListener(new MouseAdapter(){

f.getContentPane().add(textField2);

How to create a installable version for Windows and Linux/Ubuntu and Linux/RedHat ?
this code is only allowing me to reject a string the second time to try to drop in a textArea where there is all ready a string.
public GridLayoutTest() {
JFrame frame = new JFrame("GridLayout test");
connection = getConnection();
try {
statement = (PreparedStatement) connection
result = statement.executeQuery();
while (result.next()) {
byte[] image = null;
image = result.getBytes("image");
JPanel cellPanel = new JPanel(new BorderLayout());
cellPanel.add(cellLabel, BorderLayout.NORTH);
cellPanel.add(droplabel, BorderLayout.CENTER);
gridPanel.add(cellPanel);
}
}
catch (SQLException e) {
e.printStackTrace();}
}
So, two things, first...
public void DropTargetTextArea(String string1, String string2) {
Isn't a constructor, it's a method, note the void. This means that it is never getting called. It's also the reason why DropTargetTextArea textArea = new DropTargetTextArea(); works, when you think it shouldn't.
Second, you're not maintaining a reference to the values you pass in to the (want to be) constructor, so you have no means to references them later...
You could try using something like...
private String[] values;
public DropTargetTextArea(String string1, String string2) {
values = new String[]{string1, string2};
DropTarget dropTarget = new DropTarget(this, DnDConstants.ACTION_COPY_OR_MOVE, this, true);
}
And then use something like...
if (values[0].equals(dragContents) || values[1].equals(dragContents)) {
In the drop method.
In your dragEnter, dragOver and dropActionChanged methods you have the oppurtunity to accept or reject the drag action using something like dtde.acceptDrag(DnDConstants.ACTION_COPY_OR_MOVE); or dtde.rejectDrag();

I've been wondering if for example:
JTextPane chatTextArea = new JTextPane();
s.replaceAll(":\\)", emoticon());
public String emoticon(){
chatTextArea.insertIcon(new ImageIcon(ChatFrame.class.getResource("/smile.png")));
return "`";
}
can put a picture and a "`" everywhere ":)" is found. When I run it like this if s contains a ":)" then the whole s gets replaced just by the icon.
Is there a way to do it?
Here is a small example I made (+1 to #StanislavL for the original), simply uses DocumentListener and checks when a matching sequence for an emoticon is entered and replaces it with appropriate image:
NB: SPACE must be pressed or another character/emoticon typed to show image

How to add smileys in java swing?
I am making an application similar to a chat. For that purpose I have two JTextPanes, one where I'm writing and one that displays messages. This is the code that handles the transferring of text from input to display :
String input = textPane.getText();
if(!input.endsWith("\n")){
input+="\n";
}
StyledDocument doc = displayPane.getStyledDocument();
int offset = displayPane.getCaretPosition();
textPane.setText("");
try {
doc.insertString(offset, input, set);
} catch (BadLocationException ex) {
Logger.getLogger(ChatComponent.class.getName()).log(Level.SEVERE, null, ex);
}
The problem is that if i have colour on some words of the input text , the output is all coloured . So the colour is applied to all of the text when moved to display(while displayed correctly on input). Any suggestions on how i can move text properly?
Notice that same happens with other format as bold , italic etc
The text is already formatted on the input JTextPane . What i need to do
is transfer it as it is on a different JTextPane without having to check
the different style options

In the absence of a good SSCCE, I really don't know how you adding colour to the text on your JTextPane, but hopefully this method might sort things out for you :
import javax.swing.text.AttributeSet;
import javax.swing.text.SimpleAttributeSet;
import javax.swing.text.StyleConstants;
import javax.swing.text.StyleContext;
private void appendToTextPane(String name, Color c, String f)
{
StyleContext sc = StyleContext.getDefaultStyleContext();
AttributeSet aset = sc.addAttribute(SimpleAttributeSet.EMPTY, StyleConstants.Foreground, c);
aset = sc.addAttribute(aset, StyleConstants.FontFamily, f);
int len = Client.nPane.getDocument().getLength();
textPane.setCaretPosition(len);
textPane.setCharacterAttributes(aset, true);
textPane.replaceSelection(name);
}
With this you can give a different Color and Font to each String literal that will be added to your JTextPane.
Hope this new Code might help you in some way :
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.AttributeSet;
import javax.swing.text.SimpleAttributeSet;
import javax.swing.text.StyleConstants;
import javax.swing.text.StyleContext;
public class TextPaneTest extends JFrame
{
private JPanel topPanel;
private JPanel bottomPanel;
private JTextPane tPane1;
private JTextPane tPane2;
private JButton button;
public TextPaneTest()
{
topPanel = new JPanel();
topPanel.setLayout(new GridLayout(1, 2));
bottomPanel = new JPanel();
bottomPanel.setBackground(Color.BLACK);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLocationRelativeTo(null);
StyleContext sc = StyleContext.getDefaultStyleContext();
AttributeSet aset = sc.addAttribute(SimpleAttributeSet.EMPTY, StyleConstants.Foreground, Color.BLUE);
aset = sc.addAttribute(aset, StyleConstants.FontFamily, "Lucida Console");
tPane1 = new JTextPane();
tPane1.setBorder(BorderFactory.createLineBorder(Color.DARK_GRAY));
tPane1.setCharacterAttributes(aset, false); // Add these settings to the other JTextPane also
tPane2 = new JTextPane();
tPane2.setCharacterAttributes(aset, false); // Mimic what the other JTextPane has
button = new JButton("ADD TO THE TOP JTEXTPANE");
button.setBackground(Color.DARK_GRAY);
button.setForeground(Color.WHITE);
button.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
tPane1.setText(tPane2.getText());
}
});
add(topPanel, BorderLayout.CENTER);
add(bottomPanel, BorderLayout.PAGE_END);
topPanel.add(tPane1);
topPanel.add(tPane2);
bottomPanel.add(button);
pack();
tPane2.requestFocusInWindow();
setVisible(true);
}
public static void main(String... args)
{
SwingUtilities.invokeLater(new Runnable()
{
public void run()
{
new TextPaneTest();
}
});
}
}

This has been solved by merging the document models of the two panes. The solution is in this question: Keeping the format on text retrieval
