Change font in String ?

Is it possible to change font of a String like U cant do it with html coding? If I have :
String text ="this is a text";
can I change the color and the size of the text and so on, instead of the default ones?

You can set these attributes for the component which displays your string. For example, if you want to use a JLabel to display your String you can set the font, font style and colour of the JLabel.
JLabel lab = new JLabel(String);
lab.setFont(new Font("Arial", Font.BOLD, 16);
lab.setForegound(Color.red);You can do the same for JTextAreas and JTextFields. However, all of the text in these components will take the same formatting. JTextPane and JEditorPane are more flexible in that you can display text in various colours and fonts etc.
have a look at the Swing Tutorial. Follow the link to Text Components.

How to change font/ font color etc in a graphic object using JCombobox?

Hello
My program im writing recently is a small tiny application which can change fonts, font sizes, font colors and background color of the graphics object containing some strings. Im planning to use Jcomboboxes for all those 4 ideas in implementing those functions. Somehow it doesnt work! Any help would be grateful.
So currently what ive done so far is that: Im using two classes to implement the whole program. One class is the main class which contains the GUI with its components (Jcomboboxes etc..) and the other class is a class extending JPanel which does all the drawing. Therefore it contains a graphics object in that class which draws the string. However what i want it to do is using jcombobox which should contain alit of all fonts available/ font sizes/ colors etc. When i scroll through the lists and click the one item i want - the graphics object properties (font sizes/ color etc) should change as a result.
What ive gt so far is implemented the jcomboboxes in place. Problem is i cant get the font to change once selecting an item form it.
Another problem is that to set the color of font - i need to use it with a graphics object in the paintcomponent method. In this case i dnt want to create several diff paint.. method with different property settings (font/ size/ color)
Below is my code; perhaps you'll understand more looking at code.
public class main...
Color[] Colors = {Color.BLUE, Color.RED, Color.GREEN};
        ColorList = new JComboBox(Colors);
ColorList.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent ev) {
                 JComboBox cb = (JComboBox)ev.getSource();
                Color colorType = (Color)cb.getSelectedItem();
                drawingBoard.setBackground(colorType);
          });;1) providing the GUI is correctly implemented with components
2) Combobox stores the colors in an array
3) ActionListener should do following job: (but cant get it right - that is where my problem is)
- once selected the item (color/ font size etc... as i would have similar methods for each) i want, it should pass the item into the drawingboard class (JPanel) and then this class should do the job.
public class DrawingBoard extends JPanel {
       private String message;
       public DrawingBoard() {
              setBackground(Color.white);
              Font font = new Font("Serif", Font.PLAIN, fontSize);
              setFont(font);
              message = "";
       public void setMessage(String m) {
            message = m;
            repaint();
       public void paintComponent(Graphics g) {
              super.paintComponent(g);
              //setBackground(Color.RED);
              Graphics2D g2 = (Graphics2D) g;
              g2.setRenderingHint
              g2.drawString(message, 50, 50);
       public void settingFont(String font) {
            //not sure how to implement this?                          //Jcombobox should pass an item to this
                               //it should match against all known fonts in system then set that font to the graphics
      private void settingFontSize(Graphics g, int f) {
                     //same probelm with above..
      public void setBackgroundColor(Color c) {
           setBackground(c);
           repaint(); // still not sure if this done corretly.
      public void setFontColor(Color c) {
                //not sure how to do this part aswell.
               //i know a method " g.setColor(c)" exist but i need to use a graphics object - and to do that i need to pass it in (then it will cause some confusion in the main class (previous code)
       My problems have been highlighted in the comments of code above.
Any help will be much appreciated thanks!!!

It is the completely correct code

Just put DrawingBoard into JFrame and run
Good luck!

How to change font size for tracks in Songs view, iTunes 11?

I'm wondering which field in TextStyles.plist for the new iTunes 11 (I've gotten rid of Helvetica for Lucida Grande thanks to another forum on here!) - controls the font size for track title, time, artist, album, etc. as seen here - I would like to have it smaller, and have been playing around on several forums and not found the magical field to get that exact thing smaller. Many thanks in advance.

You're going to love me forever:
<key>9002</key>
<dict>
<key>- loc hint -</key>
<string>List Contents (Small)</string>
<key>font</key>
<string>HelveticaNeue</string>
<key>size</key>
<integer>12</integer>
</dict>
It's that interger "12" that's determines the size. Adjust it until you're happy—provided that it's an interger.
I actually go with "HelveticaNeue" with a size of 11. I like to see lots of tabular information at once, horizontally, without changing my resolution… within reason, e.g. Fiona Apple album titles still have ellipses.
An unfortunate aspect to this is that the row height isn't altered unless the font size specified is greater than 12—the font takes the row height along for the ride when it's bigger, but the row doesn't come along for the ride when the font gets smaller. It's likely you could change the minimum row height to be lower, in some other plist—search for something like "list contents (small)" or "list (small)" or whatever—but I don't know where that would be found, or if it could be found at all.
Nonetheless, this should address your query.

Changing Font for JLabels

Hello, I have created a small test program using a JComboBox. The purpose of this program is to change a JLabel to a certain font, based on the font that the user chooses from the JComboBox. My main concern is actually changing to font and I have no clue how to do this.
The following is the code for this test program:

          contentPane.setLayout(new BoxLayout(contentPane, BoxLayout.PAGE_AXIS));
          contentPane.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
          fontPrompt = new JLabel("Select a font: ");
          fontPrompt.setAlignmentX(JLabel.LEFT_ALIGNMENT);
          contentPane.add(fontPrompt);

                                                  //I would like the JLabel "font styles" to change font.
          else if(fontWord == "Ariel"){

          javax.swing.SwingUtilities.invokeLater(new Runnable(){
               public void run(){
                    runGUI();
}It would be great if you guys could help me. Any font style is alright.
Thanks in advance.

Hi,
Build a Font object and call setFont on the JLabel.
Hope that help,

Chat server change font tb

I have created a chat server and have included a change font button where you can go in and select from the list of fonts colours and sizes and set them for the font to change.
My question is can i get a list of fonts and colours to choose from or do I need to write them in an array string and somehow assign each one to the correct font/colour/size?
Thanks

Dynamically changing font - Ugly chars on Win 2000

Hi,
I wrote simple class called FontChooser (extends JDialog). It can be "plugged" into any JFrame to change font at runtime. Looks like ordinary font dialog, nothing special.
The FontChooser itself works (IMHO) just fine but I'm facing a problem: Almost all PLAIN fonts on Windows 2000 (sp4) have several ugly characters. For example Tahoma PLAIN 11 has ugly char '8'.
Strange is that BOLD fonts are always displayed OK - the ugly things are "covered".
The only font that's OK is Arial. (Any size, any style.) Brobably because it's the Swing default font.
Changing the font is done by this method:
* The method simply iterates through the table of GUI keys and updates every key whose name ends with "font".
Thus, FontChooser is not able to deal with different fonts at the same time.
public void updateFontKeys(FontUIResource font) {
UIDefaults def = UIManager.getDefaults();
Enumeration en = def.keys();
while(en.hasMoreElements()) {
    String key = en.nextElement().toString();
    if(key.toLowerCase().endsWith("font"))
      UIManager.put(key,font);
// Note: FontUIResource is just a new (Swing)
// "version" of java.awt.Font.I also tried to change Swing component's font using html
- instead of changing gui keys - but the result was the
same :o(
Any hint will be very appreciated :o) Thanks.

You can download FontChooser (with a simple demo app) from http://www.volny.cz/dojcland/gui/FontChoosing.zip
The archive includes binaries, source and javadoc.

Can we change data in string object.

Can we change data in string object.

Saw this hack to access the char[]'s in a String in another thread. Beware that the effects of doing this is possible errors, like incorrect hashCode etc.
import java.lang.reflect.*;
public class SharedString {
        public static Constructor stringWrap = null;
        public static String wrap(char[] value, int offset, int length) {
                try {
                        if (stringWrap == null) {
                                stringWrap = String.class.getDeclaredConstructor(new Class[] { Integer.TYPE, Integer.TYPE, char[].class });
                                stringWrap.setAccessible(true);
                        return (String)stringWrap.newInstance(new Object[] { new Integer(offset), new Integer(length), value });
                catch (java.lang.NoSuchMethodException e) {
                        System.err.println ("NoMethod exception caught: " + e);
                catch (java.lang.IllegalAccessException e) {
                        System.err.println ("Access exception caught: " + e);

                catch (java.lang.reflect.InvocationTargetException e) {
                        System.err.println ("Invocation exception caught: " + e);
                return null;
        public static void main(String[] args) {
                char[] chars = new char[] { 'l', 'e', 'v', 'i', '_', 'h' };
                String test = SharedString.wrap(chars, 0, chars.length);
                System.out.println("String test = " + test);
                chars[0] = 'k';
                chars[1] = 'a';
                chars[2] = 'l';
                chars[3] = 'l';
                chars[4] = 'a';
                chars[5] = 'n';
                System.out.println("String test = " + test);

How do I change font and colors back to default?

I have changed the font and color of the text through the tools button and the options button and the content tab. I find nothing telling me how to change the font and colors back to default font and colors. Can you advise me? I'm using Windows 7 Home Premium OS. Thanks.

Hi Brenda19605,
You can use this article to set the fonts and colors: https://support.mozilla.org/en-US/kb/change-fonts-and-colors-websites-use?esab=a&s=font&r=0&as=s
The default settings for the font are in this article:
https://support.mozilla.org/en-US/kb/Some%20text%20shows%20up%20bold%20after%20upgrade
Unfortunately for the default colors has no good reference. But for text it is black (most lower left) color, background is white (most upper left color). Unvisited links is blue (column 8, row 5) and visited link is purple (column 9, row 5).
Let me know if you need anymore help!

Email will not let me change fonts all of a sudden.

Email will not let me change fonts all of a sudden. It says I don't have the neccesay permissions in ~/library/preferences. this has just happened recently.

Who is your email provider?
You can try resetting your iPad by simultaneously pressing and holding the Home and Sleep/Wake buttons until you see the Apple Logo. This can take up to 15 seconds so be patient and don't release the buttons until the logo appears. Try again to see if the problem persists.
If yes, try deleting the mail account and adding it again.

How to change fonts in iCal?

How to change fonts in iCal? I can't harly read my calendar-tiny print size. How could I change the font size?

Your question really got me thinking. Actually, I don't think you should feel like an idiot at all. I think it is Apples failure that they made this difficult. Seriously, who would ever think to press Command and arrow to switch months? The little arrows next to the word Today are so small and inconspicuous that I remember having this very same question when I started using iCal too.
So, here is what I did to make it easier for my wife that uses iCal too.
Open System Preferences, Keyboard, Keyboard Shortcuts Tab, and finally Application Shortcuts.
Click on the Plus symbol under the right hand pane.
Select iCal from the Application list
Add two shortcuts: One named Next and the other named Previous and press your desired Keyboard Shortcut.
I assigned the left arrow and right arrow for these tasks.
Now it makes more sence for someone that is not used to Apples idotic way of doing things. ;-)
I use keyboard shortcuts all over the place. Actually, sometimes it gets me into trouble when I use someone elses computer and my shortcuts don't work. I blame their computer for it and forget it was my "tuning".

How to change font size on screen

how to change font size on screen

I'm not certain what font sizes you wish to change, when on a page you can use command and the += button to zoom in and make the fonts larger. On the finder desktop you can make what ever is on the desktop larger or smaller from the finder menu click view, custom view options, and adjust the icon size with the slider on the top, and the text using the text size box to select the size that your comfortable with.
Forgot to add these.
