JSlider

Hello i have my JSlider workds fine i want have it fill the Track when it slides i tryed
        slrSound = new JSlider(JSlider.VERTICAL,0,100,100);
        slrSound.setMajorTickSpacing(10);
        slrSound.setMinorTickSpacing(2);
        slrSound.setPaintTicks(true);
        slrSound.setPaintLabels(true);
        slrSound.setPaintTrack(true);
        slrSound.setSnapToTicks(true);
        slrSound.setBorder(BorderFactory.createEmptyBorder(0,0,10,0));But its not not filling the track ?

C'on cant be that hard to dooooooo?

JSlider + Display value in a text tool tip box

Hello,
I am new to Java. I want to display the value in a text tool tip box of the JSlider as the user moves the knob . Is there any way to achieve this.
I tried setting up the value of text tool tip in the stateChanged method. But that didn't helped

How to disable (grey-out) the ticks of a JSlider?

Hi everyone,
In my GUI, I have a JSlider that I want to be disabled (greyed out)
because it should be only actived on my application next version.
(It is important though to have it to preserve GUI appearence).
Problem is that I was unable to greyout the ticks even though
already managed to grey out the slider and the number labels.
Right now, it is pretty uggly to have a partial disabled slider,
because due to ticks not being disabled.
Questions:
1) Does anyone have an idea of how to do it?
A small part of my code is shown below:
JSlider dynSl = new JSlider();
dynSl.setMajorTickSpacing(1);
dynSl.setValue(0); //Default
dynSl.setMaximum(7);
dynSl.setMinimum(0);
dynSl.setPaintLabels(true);
dynSl.setPaintTicks(true);
dynSl.setFont(new java.awt.Font("Dialog", 0, 9));
dynSl.setSnapToTicks(true);
dynSl.setEnabled(false);
// small code just to put the numbers of the slider smaller
Enumeration enum = dynSl.getLabelTable().elements();
while (enum.hasMoreElements()) {
JLabel elem = (JLabel)enum.nextElement();
elem.setFont(new Font("Dialog",0,8));
elem.setEnabled(false);
2) If not possible, how do I change the colour of a JSlider (including
the Ticks)?
My idea is to change Slider's colour to the same grey colour one used
to disable it, making at the end the slider look as if it was disabled.
Thanks in advance,
Jorge

Hi again,
Thanks for the help.
I was trying to avoid not having the ticks at all but it seems to be
the best choise because I could not solve the problem of greying out
them.
I did some more troubleshooting though and for my surprise, if I use
the same code alone, i.e, a simple frame with just the slider it works
fine. I even thought that it was related with having Windows LnF as
opposed to Metal (Java) LnF, but that was not the problem.
The only thing it comes to mind, is that there may be some problem by including the slider on a GridBagLayout !?!?!?
Anyway,
What has no simple solution, solved is! :-)

Is there any way to animate a JSlider and a JProgressBar?

Hi all,
I'm working on an assignment using JSliders and JProgressBars in a Java application. I've been trying to let my JSlider and JProgressBar move by itself i.e. reset the slider's current value to a new one after a specific period of time...Tried using a timer and thread but just can't seem to get it moving. Is there any way to set the JSlider to update itself after a specified time period? Same goes for JProgressBar?
At my wits' end, really appreciate if anyone can offer me some advice and help...Thanks.

Hmm...use a timertask that resets the value and triggers a repaint in the event thread? That should work at least in theory.

How to place a JSlider in the middle of an image?

Hi,
Here is the deal. I have an image inside a JLabel. That JLabel is inside a JPanel, which in turn is encompassed by a JScrollPane. This image represents some curve or a frequency function, lets say for instance a sine curve. What I need to do is have a slider, positioned (just to keep things simple for now) in the middle of that image, not above or below or to the side of an image, but rather directly over it. Thus, blocking a small section of the image from view. So that the user can drag the mouse cursor along the (horizontal) slider and see the different values on that curve. I dont know of any LayoutManager that would allow me to place a JSlider at an arbitrary position on top of a JLabel, besides just using a Null Layout. However, when I use a Null Layout my scroll bars disappear and the JSlider itself just sits there doing nothing, without reacting to any mouse movements, and mroe importantly as soon as the application is resized, the JSlider disappears completely.
Any comments/code snippets would be greatly appreciated.
Thanks,
Val

JSlider in JTable

Hi,
I insert JSlider in a column of a JTable, redefining renderer and editor. The problem is that when I resized the size of the JTable (or the column with the sliders), the sliders are not resized. They are only resized if I move another window over them. Is is a repaint I have to apply ? The problem is that I do not know where to apply it.

How to set the color of ticks in JSlider

Hi,
Question about JSlider.
I am trying to set various colors between the ticks. However, I have gone thro' the javadoc of JSlider but find no such API.
How could I go this?
Thanks in advance for any inputs and ideas.
Wing

Here is quick demo about customize thumb.
It is similar for customize other part of JSlider.
You can use setUI to force use your own UI.
Create your UI, the better way is extend from existing UI,
for example: BasicSliderUI or MetalSliderUI (or... depend on L&F you want).
Check the BasicSliderUI and MetalSliderUI API
customize the paintXXXX method, that's it.
Good Luck.
import javax.swing.*;
import java.awt.*;
import javax.swing.plaf.metal.MetalSliderUI;
public class Test {
public static void main(String[] args) {
    JFrame f = new JFrame();
    JSlider slider = new JSlider();
    slider.setPaintTicks(false);
    slider.setUI ( new MetalSliderUI() {
      public void paintThumb(Graphics g) {
          Rectangle knobBounds = thumbRect;
          Color color = g.getColor();
          g.setColor(Color.red);
          g.fillOval(knobBounds.x, knobBounds.y, 15,15);
          g.setColor(color);
    f.getContentPane().add (slider);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

JSlider randomly missing tick labels

Hello everyone,
I am having a problem with JSliders. I have an application that has several JSliders throughout. They are vertical, min=100 and max=1000, with major ticks every 100, and minor ticks every 25, and the ticks and labels are painted.
I have noticed that out of say 10 such sliders in my application, perhaps one or two sliders are randomly missing some ticks. For example, the labels will read 100, 200, 300, 400, 500, 600, 700, 900, 1000 (with the 800 just missing). The space for the text is there, but no text.
As I mentioned, this doesn't always occur. It occurs perhaps on one or two sliders out of 10 every time I start the application. So this would seem to me to be related to a threading issue.
Here is the constructor that creates the panel that has the JSlider in it:
 try{
 SwingUtilities.invokeAndWait( new Runnable(){ public void run(){
 // INIT GUI & CUSTOM INIT
 initComponents();
 depthJSlider.putClientProperty("JSlider.isFilled", Boolean.TRUE);
 catch(Exception e){ Util.handleExceptionNoRestart("Error building Log Table", e); }
Here is initComponents() which actually does the work:
 private void initComponents() {
 depthJSlider = new javax.swing.JSlider();
 depthJSlider.setMajorTickSpacing(100);
 depthJSlider.setMaximum(1000);
 depthJSlider.setMinimum(100);
 depthJSlider.setMinorTickSpacing(25);
 depthJSlider.setOrientation(javax.swing.JSlider.VERTICAL);
 depthJSlider.setPaintLabels(true);
 depthJSlider.setPaintTicks(true);
 depthJSlider.setSnapToTicks(true);
 depthJSlider.setToolTipText("<html>\nEvent Log Depth Slider \nThis slider allows you to specify the maximum number of visible\
events \nwhen the \"Refresh Log\" or \"Start Auto-refresh\" buttons are pressed.</html>");
 depthJSlider.setMaximumSize(null);
 depthJSlider.setMinimumSize(null);
 depthJSlider.setPreferredSize(null);
 gridBagConstraints = new java.awt.GridBagConstraints();
 gridBagConstraints.gridx = 0;
 gridBagConstraints.gridy = 0;
 gridBagConstraints.fill = java.awt.GridBagConstraints.VERTICAL;
 gridBagConstraints.weighty = 1.0;
 gridBagConstraints.insets = new java.awt.Insets(5, 5, 5, 10);
 tableJPanel.add(depthJSlider, gridBagConstraints);
 }Does anyone have any ideas at all why some of the labels might be missing?
(Please drop a line to [email protected] if you have any thoughts!)
Sincerely,
Ian

JTextField and JSlider

Hi!
I have a JSlider and a JTextField. I would like them to "update" eachother...
When the user is changing the JSlider, I need the String in the JTextField automatically to update the recieveing data from the JSlider, and vice versa.
I dont know how to do this, and Im new to Swing. However, why Im stuck is because I consider the JTextField as an already constructed component. Dont I only when declaring it decide what the showing String should be?
Many thanks for help

I need the String in the JTextField automatically to update the recieveing data from the JSlider, and vice versa.ChangeListener for slider and DocumentListener for the textfield's document

JSlide problem

Hi,
I would like to know wether is possible inside stateChanged JSlider event to know why it is firing.
I mean, to know wether the user is dragging the thumb or just clicking at the slide. I know about valueIsAdjusting, but both return true.
If it's not possible here in this event, where could I get it?
Thanks a lot

Did you ever figure this out? I am running into the same thing...

Problem with JSlider

I have a JSlider whose minimum value can be -50 and maximum value +50. Why function setValue(int n) doesn't work?
Advance thanks!
Best Regards!

Come on, you've posted here enough to know you should put the exception your message. Without it you're asking, "I'm getting an error, can someone tell me how to fix it?". Need more information. Post the stack trace. Post some code (using the code tag as shown at http://forum.java.sun.com/faq.jsp#format).

Style JSlider

Hi!
I'm about to style a JSlider. It's not enough to change a few parameters, I mean really style with images.
What is the best way to do that? I did try to create a subclass of JSlider and in that override the paint method and paint the slider with images. That works, but, not well. For example when I drag, the slider knob gets stuck at some places, which looks really weird. But as soon as I release the mouse button, the slider updates itself and looks well again.
I also considered creating my own look and feel by extending SliderUI.
How would you go about this problem?
Thanks!

JSlider or similar for controlling position in sound files help please.

You know how winamp, wm player , etc, and JMStudio all have a "slider" bar to control position, along with a "numeric readout" of the current position.
Fairly new to Java, but know this isn't a difficult thing to do, just haven't found out how to do it.
Do not care if it is with JavaSound API or JMF, either is fine, just learning.
Have read up on Sliders at:
http://java.sun.com/docs/books/tutorial/uiswing/components/slider.html#labels
But do not understand how to implement it with Audio file usage.
My goal as a new programmer is to create a simple audio playing Applet:
For a GREAT idea on what it will basically do check out:
JMStudio:
http://java.sun.com/products/java-media/jmf/2.1.1/jmstudio/jmstudio.html
My goals are to have:
Applet
GUI with: Pause/Play button and a SLIDER to control position, just like described.
Have it load and play an audio file when a link is clicked on using the PARAM tag from html
I know about the open source/commercial products,,,, but I'm trying to learn, and those are too in depth to try and learn from right now, trying to take baby steps, and having difficulty finding anything beyond play()
loop() and stop()
searched google, groups, yahoo with various phrases.
Thank you!

You have to use a JSlider and combine its events with the setMediaTime method of the player.

Using JSlider as table component

Ive been having some problems using JSlider in tables... Ive written several cell editors and renderers but this is the only one that gives me problems. Here is simplified code that i think should work but doesn't:
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTable;
import javax.swing.JSlider;
import javax.swing.table.TableColumn;
import javax.swing.table.TableCellRenderer;
import javax.swing.table.AbstractTableModel;
import java.awt.FlowLayout;
import java.awt.Component;
import java.awt.event.WindowEvent;
import java.awt.event.WindowAdapter;
* A main frame with a table in it... wish it had sliders...
public class TestSliderTable extends JFrame
    /** Creates new TestSliderTable */
    public TestSliderTable()
        addWindowListener(new WindowAdapter()
            public void windowClosing()
                System.exit(0);
        setUpTable();
    private void setUpTable()
        JTable table = new JTable(new SomeDumbTableModel())
            public TableCellRenderer getCellRenderer(int row, int column)
                return new JSliderTableCellRenderer();
        JPanel panel = new JPanel();
        panel.setLayout(new FlowLayout());
        panel.add(table);
        setContentPane(panel);
        pack();
    public static void main(String[] args)
        TestSliderTable frame = new TestSliderTable();
        frame.setVisible(true);
* A simple cell renderer that should render sliders...
class JSliderTableCellRenderer extends JSlider
    implements TableCellRenderer
    /** Creates new JSliderTableCellRenderer */
    public JSliderTableCellRenderer()
        super(0, 10, 5);
    public Component getTableCellRendererComponent(JTable table, Object value,
                                                    boolean p3, boolean p4,
                                                    int row, int column)
        int newValue = ((Integer)value).intValue();
        setValue(newValue);
        return this;
* a simple table model with Integers as values...
class SomeDumbTableModel extends AbstractTableModel
    public SomeDumbTableModel() { }
    public int getRowCount() { return 10; }
    public int getColumnCount() { return 1; }
    public Object getValueAt(int row, int column) { return new Integer(row); }
}Anyone have similar problems or know anyway around this?

Have you tried this:
