Scroll bar hides bottom of JTree

I have a dialog with a JTree in a JScrollPane and it's possible to have the dialog at just the right size that the scroll pane becomes confused. Both scroll bars are displayed and when I try to scroll down to the bottom of the tree, the scroll pane keeps resetting itself so that the horizontal scroll bar covers the bottom of the tree. If I want to see the bottom of the trr, I must resize the dialog. I looked in the bug database but didn't find anything similar to this problem.

It's not that the vertical scrollbar is the wrong size. It's that the VSB's thumb won't stay all the way at the bottom. Instead, it springs back to a position approx. halfway. The problem occurs when there's enough text in a tree entry to force the display of the HSB and the VSB's thumb is all the way at the bottom. I can't include a screen shot here as the boss doesn't want to have to mess with proprietary info and non-disclosure agreements, so I hope the description I gave is sufficient.

Bug? scroll bar hides behind filmstrip in Grid view

In Library Grid view, when scrolling to the bottom of the grid, the scroll bar slider gets hidden behind the film strip at the bottom of the window.
OS: WinXP SP2, 4GB RAM

Okay, I will answer my own question in case anyone else sees the problem.
When I am viewing my large catalog with only three thumbnails across in LR, I lose the little button to slide up and down. When I change Grid View to show four or more thumbnails, the button reappears. I'd suggest this is a bug needing fixing.

Help with code for inserting horizontal scroll bar in photo gallery in Business Catalyst site?

Hi,
I am using Business Catalyst and Dreamweaver to create a trial site.
I am not sure if this is the correct forum to post this request but anyway I have inserted a photo gallery module at the bottom of the sidebar in the homepage of my test site.
Can anyone advise on whether jquery or any other code can be inserted into the page or module code that will replace the "next" hyperlink below the first 4 photos with a horizontal scroll bar at bottom of the gallery so users can just scroll through all 12 images ?
Kind Regards, Matt.

Alyssa,
Have you tried putting this rule back as it was originally:
/* Submenu that is showing with class designation MenuBarSubmenuVisible, we set left to auto so it comes onto the screen below its parent menu item */
ul.MenuBarHorizontal ul.MenuBarSubmenuVisible
    left: auto; /*was 9px*/
    color: #EF9CCF;
    background-color: #FFF;
That is, changing your 9px back to auto.
And giving us a link (as you did) is much better than printing out the code for us! Thanks!
Beth

Hide TextArea scroll bar

Has anyone found a way to hide, edit, alpha the scroll bar
with the TextArea component (flash CS3 - AS2)?
I can hide the border, alpha the background, but no way to
hide the scrollbar... arggg.
my example... when you click one of the buttons (bottom) you
will notice the scroll bar (right) flickers then disappears and the
text also shifts. I hid the border and alpha the background but
need to get rid of the scrollbar.
http://dev.webadmin.ufl.edu/~akirby/dynamicFlash2/index2.html
thanx in advance

"If you can tell me what you are trying to accomplish..."
- Folks want flash on their home page but don't know Flash or
have the app.
- I provide this "system" to them.
- They upload the files to their server
- They include the satay method of embedding the flash into
their markup (existing web page based off of official templates
provided by my office)
- All they need to maintain are the text files, images, and
css (for styling text).
- No need to open/use the Flash application to maintain this
system.
It works perfectly other then the scroll bar flickering and
text shifting bug(s) that occurs within the TextArea Component.
That's the only issue that is causing this project to be held up.
"They are always overly coded..."
Myself and two other Flashers have developed this system
(timeline) as slim and as simple as we possibly could. I'm sure
there's a better way to produce this system by using timeline
actionscripting... but our skills are limited.
"hard to trace their logic."
Logic is... not to have to open/use the Flash app to maintain
this system. Only maintain external files.

Remove/Hide scroll bars in scroll panes.

Hi all,
I am pretty new to action script. I am building a photo gallery and I am loading the thumbnails from an XML file into a scroll pane dynamically. As the scroll pane fills up, it gets wider to accomodate the thumbnails. There is one row, and eventually, I want to have the user be able to mouse left or right and have the scroll pane scroll, versus clicking on the bar or the left/right arrows. However, in order to accomplish this, I need the scroll bars to disappear!
Is there anyway to either remove or hide both the x and y scroll bars on a scroll pane? My scroll pane is called: thumbPane.
Thanks in advance!

Hello friend,

THANKS.

How do I view the Horizontal Scrolling bar and status bar at the bottom of the screen. I can only see the top menus, toolbars and vertical scroll bar?

Before the most recent upgrade, the bottom horizontal scrolling bar and status bar appeared on my screen. Now since upgrading, I cannot see the. Anyone ideas how to restore them?

If you haven't already, you could force-quit Quicktime by using the menu option from the desktop (finder) and choose Quicktime.
Not sure what you have frozen on the screen, be it a failed movie, or some unusual screen shot. If you can find by date (created) you may be able to look for .mov or quicktime suffix name or other video file content to delete it.
And you may have to restart your computer and perhaps run repair disk permissions from Disk Utility's first aid on the hard disk drive in your computer.
Not sure if all that would help now, but it is something a few days late...!
Good luck & happy computing!

Edited by: 984493 on Mar 4, 2013 1:05 AMHello
It's the issue of browser. There is no setting for it. most probably you are not using
separateFrame=Truein you formweb.cfg file. It's allow the applet opening in another window.
In you issue, may be you have toolbar visible in the browser. if you use the browser full screen you didn't get that.
Hope this helps

Scroll bar hidden by Jtree.setPreferredSize()

After a lot investigation, I have found that using the method setPreferredSize() for a JTree object has a strange side effect. In fact the vertical Scroll bar does not display.
In the following program, all works fine because the setPreferredSize() is commented out. Now if you get rid of the // in front of this line, then you will notice the the scroll bar has disappeared.
any idea ? Thanks. Here is my code.

For what it is worth -- I've observed this on my project, too.
I just setPreferredSize on the JScrollPane that held the JTree, rather than on the JTree itself.

How can I hide horizontal scroll bar?

Some websites use CSS code (overflow-x: hidden or overflow-y:hidden), that shows the horizontal scroll bar while the frame on the website is centered and only 800 pixels wide, but I really don't need my horizontal scroll bar to show up. So how can I hide it?
Thanks!

If you use overflow: hidden then you shouldn't see a scroll bar (overflow:scroll does that). 
If that doesn't work then try to add the !important; or use the code in Stylish or to userContent.css in the chrome folder.

How can I hide the scroll bar in TextArea?

How can I hide the scroll bar in TextArea?

Hi. To remove the horizontal scrollbar you can do this:
textArea.setWrapText(true);
To remove the vertical scrollbar you can do this:
ScrollBar scrollBarv = (ScrollBar)ta.lookup(".scroll-bar:vertical");
scrollBarv.setDisable(true); and set the opacity to 0 in the css file:
//css file
.text-area .scroll-bar:vertical:disabled {
    -fx-opacity: 0;
}Here is an example:
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ContextMenu;
import javafx.scene.control.MenuItem;
import javafx.scene.control.ScrollBar;
import javafx.scene.control.TextArea;
import javafx.scene.input.ContextMenuEvent;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class TextAreaSample extends Application {
    @Override
    public void start(Stage primaryStage) {
    final TextArea textArea = new TextArea();
        textArea.setWrapText(true);
        StackPane root = new StackPane();
        root.getChildren().add(textArea);
        Scene scene = new Scene(root, 300, 250);
        primaryStage.setScene(scene);
        primaryStage.show();
        scene.getStylesheets().add(getClass().getResource("style.css").toExternalForm());
        ScrollBar scrollBarv = (ScrollBar)textArea.lookup(".scroll-bar:vertical");
        scrollBarv.setDisable(true);
    public static void main(String[] args) {
        launch(args);
}

Is there any way to hide or remove the scroll bars when programming?

I wish the vi which builded by app builder can display a interface without the scroll bars even before it runs. Thank you very much!

As was answered here, you can only hide the scoll bars when the VI is running. If you need to enter data or set options before running, then you should redesign the application with a "Go" button or a pop-up and not rely on the user to press the run arrow. Putting the controls inside a while loop would be sufficient and should be easy to do. It's that or live with visible scroll bars.

What happens when the scroll bar moves to the bottom by itself?

When I am browsing, the scroll bar moves downward all of sudden to the bottom of the arrow. When you click on the scroll bar to move the page back to the top, it automatically moves back the scroll bar back to the bottom of the page. I have tried reloading the page, going forwards and backwards, and refreshing the page but it still does this problem. The only way to fix this problem is you have to close Firefox and reopen the browser. Is there a solution?

Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

How to remove a black border box that continously tabs to each field automatically till end of web page; restarts to top of page, cannot stop this box. Scroll bar cannot controlled with mouse, returns auto to top of scroll slide, never remaining at bottom

how to remove a black border box that continously tabs to each field automatically till end of web page; restarts to top of page, cannot stop this box. Scroll bar cannot be controlled with mouse, scroll bar returns automatically to the top of scroll slide every time I move the bar to the bottom of the scale. Also, there's a rectangular text box (with black background and white text) that is always on the desktop that emulates a typed text, HTML, or cmd function.

Also, there's a rectangular text box (with black background and white text) that is always on the desktop that emulates a typed text, HTML, or cmd function.
The first two problems (box cycling from element to element on page, scroll bar returning to top) can be caused by a stuck (or defective) Tab key on the keyboard. Such damage can be caused by a liquid spill; just one tiny droplet is enough to short a wafer switch under one key.
The last issue (black box, white text - sounds sorta like a debugger window) I haven't seen, but could be caused by something similar.
To check for that, try using a different keyboard. If you're using a wireless keyboard, turn it off and see if the oddities stop.
