How To Add scrollbar in Spark list which will work on mouse movement ?

Hi,
I want to add scrollbar in Spark list which will work on mouse movement, i.e instead scrolling down it will sense mouse position and scroll automatically. I could not find a way to handle this with horizontalLayout.
I tried hovering on list and setting ensureIndexIsVisible(index) but hovering element index is not present in the Spark List.
Any idea on this will be highly appreciated.
Thanks in advance

How to add scrollbar to the JInternal Frame

How to add scrollbar to JInternal Frame?
I have One JInternal frame i want it should have a scrollbar when we reduces its size.

Add Scrollbars to Jframe

I want to add ScrollBars to the JFrame(Parent screen), when the internal frame(child scereen) size is greater than the size of the JFrame. and those scroll bars should have the control over the child screen.
For example, when the height of the child screen is greater than the parent screen, then Vertical scroll bar should be added to the parent screen. So, In this case i couldn't view the bottom of the child screen without moving the scroll bar. when I move the scroll bar, I should be able to view the lower portion of the child screen.
Child screen size is fixed and it can be bigger than the parent screen in some cases. If it is bigger, then it should be within the boundary of the parent screen and all the components should be viewable to the user. In this scenarioo, I can think of only adding scrollbars to the parent screen and using that to view the entire child screen.
Is there anyway to do this?
Thanks,

Add Scrollbar to Array

Does anyone know if it is possible to add a scrollbar to an array? I want to replace the index display with a scrollbar.
My first thought to do this leads me to believe that I would need to fix the size of the arrayl. Can the size of an array be fixed?
Thank you,
-Ron Synakowski

you can definitely attach a scroll bar control and an array, there you just have to attach the index to the scroll value and update it on the scroll value change event. Also you should update the maximum scroll value property to be the size of the array (this can be done periodically or as a user defined event), so you don't have to fix the array size, I have done this in the past without too much work, but it would have been nice to allow the array control to have this option built in (maybe LV8).

Can we add scrollbar to JOptionPane.showConfirmDialog()

Hi,
Can we add a scroll bar to JOptionPane.showConfirmDialog() so that the contents(messages) which are to be displayed are present in scrollbar so that the buttons will be visible to the user like OK, CANCEL.
Currently when the message is large the buttons will not be visble in the screen.
So, it is possible ? Or there is any other alternative for the same.
Thanks.

Is there another library that I have to import? I recieve this error when I try to compile...
isPrime.java:53: cannot find symbol
symbol : variable sb
location: class isPrime
     JTextArea area = new JTextArea(sb.toString() );
I have javax.swing.* imported as of right now...
     JTextArea area = new JTextArea(sb.toString());
      area.setRows(25);
      area.setColumns(100);
      area.setLineWrap(true);
      JScrollPane pane = new JScrollPane(area);
       JOptionPane.showConfirmDialog(null,
     pane,
       "Test", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE);
/*         JOptionPane.showMessageDialog(null,
           printArray(array),
     "Thanks for using Reverse Array", JOptionPane.INFORMATION_MESSAGE);
*/       the comment text is what I eventually wish to print((I simply hid it from the compiler so I could play w/ the code you provided)... it is the first 'n' number of primes up to which I'd like to be able to scroll through for large prints over 100 primes.
thx for the help

How to add scrollbar to jpopup menu

Hi everyone,
Do u know how to add a scrollbar to jpopup menu ?

Menus don't scroll, and shouldn't scroll. Given that, you shouldn't try and use JPopupMenu at all... rather, create your own component that implements the look and behavior you want. It will be far easier and less frustrating.
Either that... or you should re-think what functionality you are trying to provide, and how you are trying to implement it. A scrolling menu just seems like a counterintuitive wacky UI design to me.

Add scrollbar to JTextArea

Hello!
I dont understand why this is not working:
When I have added the scrollbar I can not print out anything on the JTextArea, if I just add the JTextArea I can print out to it.
part of my view
          //Display (Do not forget to make the scrollbar after logic is implemented)
          JScrollPane scroll = new JScrollPane(display, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
          JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
          scroll.setLayout(null);
          scroll.setLocation(10, 10);
          scroll.setSize(320, 270);
          //display.setLocation(10, 10);
          //display.setSize(320, 270);
          display.setEditable(false);
          display.setLineWrap(true); //Start a new line instead of making display area bigger
          display.setWrapStyleWord(true); //Words will not split in the middle, the full word will instead show on the next line
          middle_left.add(scroll); //Add to holderThis is how I take inputs that will go into the JTextArea
     // Sets the text displayed on the display area
     public void setDisplayArea(String message){
          display.setText(""+message);
     I must defently be missing something, can you please help me figure out what it is.
This is part of an assignment, please do not spoonfeed me with code.
Regards
Martin

Yes the problem went away when I comment out this line //scroll.setLayout(null);
Why is it so?
Can you please explain or guide me to a webpage with an explonation if it is alot to explain.Like abillconsl said, a JScrollPane already has a perfectly good layout manager. So instead it's up to you to explain why you decided to make it have a null layout manager instead.
If the explanation is "I don't know anything about layout managers so I can't explain that, it just seemed like a good idea at the time" then you should read the [Layout Managers tutorial|http://java.sun.com/docs/books/tutorial/uiswing/layout/using.html].

Add scrollbars to OOB SharePoint Blog site

All:
I created an OOB SharePoint 2013 Blog site used for news updates. The problem is that on smaller device form factors (e.g. tablets) or when I shrink browser window on the desktop, no horizontal or vertical scrollbars are visible. My users
cannot read or access the blog post info (especially on the right hand side).
How can I enable scrollbars in an OOB Blog site so that viewers can access all of the content?
Thanks,
Bill
Bill Davidson

Hi,
According to your description, when you shrink the browser window or using a tablet, the scrollbars don’t appear.
Is this issue only occur to Blog site but the other site templates?
What version of the browser do you use?
It would be better if you can provide more details about your browser or if there any customization has been made on your Blog site.
Feel free to reply if there any progress.
Thanks

CS6 ScriptUI Scrollbar issues

We're working on building a palette with a scrollbar. However, we're running into an issue with the display in CS6. We've gotten it to display correctly on Windows and Macs in previous versions of Bridge, but CS6 seems to have a bug even after the most recent update (version 5.0.1.21).
The scroll bar appears as below.
When we changed the dimensions of the scrollbar, we found that not only was the scrollbar distorted but it's actually oriented horizontally to control the vertical position.
We've tried nesting the scrollbar in a group or giving it a separate panel, as well as giving those panels and groups a specific column orientation, but nearly all of those results give us something like the following:
The following code was our last iteration that gives the above output:
#target bridge
if (BridgeTalk.appName == 'bridge')
    // dimension and font variables
   var fF = ['fill', 'fill'];
   var fT = ['fill', 'top'];
   var lblSize = [60, 15];
   var lblBounds = [5, 10, 60, 27];
   var etFont = ScriptUI.newFont ("Arial", 11);
   var etBounds = [10, 10, 200, 27];
    // Create the TabbedPalette object, of type "script"
    var tbPalette = new TabbedPalette( app.document, "CSU Metadata", "CSU_Metadata", "script", "right", "bottom");
    // Create a ScriptUI panel to be displayed as the tab contents.
    var panel = tbPalette.content.add('panel', "x:0, y:0, width:300, height:500", "");
    var tbPanelSbGrp = tbPalette.content.add('panel', "x:302, y:0, width:200, height:500", 0, 0, 20, 500);
    tbPanelSbGrp.orientation = 'column';
    var tbPanelSb = panel.add('scrollbar', "x:302, y:0, width:40, height:500");
    tbPanelSb.stepdelta = 10;
    tbPanelSb.jumpdelta = 40;
    tbPanelSb.onChanging = function() {
     var scrollVal = Math.round(this.value);
    this.value = scrollVal
Has anyone found a work around for this problem? I've seen the same problem mentioned elsewhere but without a solution:
http://www.ps-scripts.com/bb/viewtopic.php?f=9&t=4915
http://feedback.photoshop.com/photoshop_family/topics/extendscript_ui_not_drawing_correctl y_in_bridge?from_gsfn=true

I have given up on this. More than a year has passed and the Bridge ScriptUI is still non-functional. I am looking for another solution for my workflow so I can ditch Bridge/Photoshop and find a vendor that supports their products.

}I am keeping the size down because if it gets bigger it goes off the screen. I would like to know how to add scrollbars.
I would also like to display something whenever someone clicks in one of the squares. How do I get the location where the mouse was pressed?
I only started working with JFrames yesterday so please keep it simple(if possible).
Thanks for any help.

JScrollPane in a JFrame scrollbars visible but not functional no thumbtabs

Here is the code that I compiled and run on J2SE v. 1.4.2 (runtime b28). I looked through the various related articles and nothing seems to help with this issue. The scrollbars appear along with the panel but the thumbtabs are not present. Any help would be appreciated.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Test {
public static void main(String[] args){
    Test rce = new Test();
    JFrame frame = new JFrame("Test Scroll");
    JScrollPane scrollBar = new JScrollPane();
    scrollBar.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
    scrollBar.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
    Component rcePage = rce.createComponents();
    scrollBar.getViewport().add(rcePage, null);
    frame.getContentPane().add(scrollBar, null);
    frame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
    frame.pack();
    frame.setSize(400, 400);
    frame.setVisible(true);
public Component createComponents() {
    JPanel pan = new JPanel();
    JLabel label = new JLabel("This is a Test!");
    pan.setBorder(BorderFactory.createEmptyBorder(
        0, //top
        0, //left
        0, //bottom
        0) //right
    pan.setLayout(null);
    label.setBounds(100, 100, 80, 20);
    pan.add(label);
    return pan;
}

This is a very common mistake. When you put a JPanel in a scrollpane, the scrollpane will use the panel's preferred size to determine if scrolling is needed or not. If the panel is using a LayoutManager this is generally done for you automatically. But in your case you set the layout to null, and then it is your responsibility to make sure that the getPreferredSize() method of the panel returns the correct size.
One way to fix this in the code you posted would be to override the getPreferredSize() of the panel, like so:
    public Component createComponents() {
        JPanel pan = new JPanel() {
            public Dimension getPreferredSize() {
                return getSize();
    }Then the scrollbars will appear if you make the frame smaller.
But what I really suggest is that you use a LayoutManager.

Add Scrollbar
