Scrollbars in the middle of panel
My panel scrollbars are in the middle of the panel (see attached screenshot). I don't know how I did it. Worse though, I don't know how to get them back to the edges of the panel.
Any help is appreciated. BTW, I'm using LV 8.6. If I create a new VI, everything is normal so I could just copy everything over ...
Thanks,
H

How to get only the middle panel to resize and show a scrollbar ?
I have a window(frame) that has three panels - top, middle and bottom. When the window is shrunk vertically, I need a scrollbar to show up for the middle panel only. So the maximum vertical shrink possible would be the sum of the top and bottom panels plus some small amount (to see the middle panel scroll bar). So the top and bottom panels would always show completely (height wise). Please review my code and suggest corrections. I've tried couple of different ways but without success....The code below is my most recent attempt.
Thanks.....

1. Sample code
ScrollablePanel panel = new JScrollablePanel(...);
panel.setScrollableWidth( ScrollablePanel.ScrollableSizeHint.FIT );references a JScrollablePanel - i'm assuming this is a typo and should read new ScrollablePanel()?
Anyway I've tried this but it still does not show a vertical scroll bar for the middle panel:

Open "Java Preferences" either from spotlight or your utilities folder...it's probably going to say you need to install a java runtime. Then just click install!

Scrollbar postion in the middle of scrolling context
I'm working on a project where i give the user the ability to zoom an image,
the problem is when the user zoom the image, the right and left scrollbars are positioned at the beggining of the FigureCanevas.
What i want is when redrawing the image, the scrollbars should be in the middle of their scrolling context, what will give him a look on the center of the image after redrawing.
Any idea.
regards.

Setting the scrollbar to be by default in the middle of the scrollpane
I was wondering if there was a way to set the JScrollBar to be at the middle of the scrollpane by default. I have a handle to the scrollbar and can determine the min and max of it's range, but I don't see a place to set the scrollbar position.

Can't see the middle panel of iTunes store
Hi!
I recently upgraded to iTunes 10.7(21) on my Mac. Now, whenever I go to the iTunes Store, I don't see the middle panel where the recommended apps/music/songs, etc. can be seen.
Below is a screenshot:
Any suggestions to solve this would be appreciated.Perhaps try the iTunes Store loads partially or returns "Error 306" or "Error 10054" section in the Specific Conditions and Alert Messages: (Mac OS X / Windows) section of the following document:
iTunes: Advanced iTunes Store troubleshooting -
Screen just keeps cycling a four-square panel in the middle for hours. Is this normal?
Screen just keeps cycling a four square panel in the middle for hours - is this normal?
Hi yacht61,
I would say that is definitely not normal! Are you having trouble logging in or converting a file? For starters, please try the following:
Clear the browser cache and try again.
Try a different web browser.
If the problem occurs when you're converting a file, try converting a different file.
Let me know if the problem persists, and also whether it occurs when logging in or converting.
Best,

How do I change the defualt grey scrollbar and the grey movie player control panel?
How do I change the defualt grey scroll bar sliders and the grey control panel for the movie player using Dreamweaver. Is there a way to change the color of these items using CSS?
Any info would help.I have not had to write any code yet.
Well that's going to have to change. :-))
For Windows Media, set the autostart attribute value to "false" and "0"

If you can convert your WMV and FLV files to MP4s, you'll have video that can be viewed in all modern browsers plus Smartphones.

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,

My iPad 1st gen has a large grey stripe in the middle of the screen. Any help would be appreciated
It was not dropped and has no other damage and works fine EXCEPT i cannot view the middle part of the screen.
From other posts and searching the web this seems to be a "KNOWN" 1st Gen issue and I am ot the only one.
Anyone had any luck with getting this solved ??
My solution was I just bought a new iPad 4th Gen because I did not want to be without my favorite device but am discouraged by the fact Apple is NOT commenting on this issue or offering a fix
I am hoping that this 4th Gen did not come with a 2 year expiration date - for almost $800 bucks it should last until I decide - not until it is completely disabled by a manufacturer defect as in what happened with my 1st Gen
I still expect my 1st Gen to work and need any suggestions in dealing with the issue as (OF COURSE) the device is no longer under warranty$100 you can buy a replacement screen => http://www.ifixit.com/iPad-Parts/iPad-Wi-Fi-Front-Panel-Assembly/IF180-000?utm_s ource=ifixit_guide&utm_medium=guide_intro&utm_content=required_items&utm_term=ip ad_wi-fi
Then use the guide to swap out the screen => http://www.ifixit.com/Guide/Installing+iPad+Wi-Fi+Front+Panel+Assembly/4174/1
I had a similar issue last year when I bought my new Samsung HDTV. There was a strip of discoloration going down the middle of the screen about 3 inches wide. Samsung replaced the screen as there was nothing that could be done to fix it.
I imagine this means the crystals in the screen are somehow damaged. It may not be your fault, they could have just gone bad from bad manufacturing or whatever. There is software for desktop computers that runs through series of tests for attempting to correct issues with an LCD screen, but it would be difficult to run this software on an iPad screen. I doubt there is an app that does anything similar, but you can check the app store or the Cydia market if jailbroken.
Good luck -
How to align flash content to the middle of the screen in browser?
I am currently building a website in flash cs5.5 using AS2.0. One of the pages is 1024px wide by 1536 height. I want the screen to show only the first half of the screen and then the user has to scroll down using the browser scrollbar to see the second half of the screen.
Below is the html code. I have changed the 'overflow' from hidden to auto so that the website is scrollable. However when i preview the website in the browser, it is aligned to the left. Even though below (highlighted in red) it says 'middle'. This is not what i want, i want the website to me aligned in the middle so that there is a border on either side of the website.I have tried numerous things to fix it but all to no avail. Could someone please help. Let me know if you need anymore info.
Thanks

Get rid of the 100% w/h and give flashContent a set width (1024).
Then you can give the right and left an auto margin... centering the <div id="flashContent">.

My itunes won't sync my ipad and closes down in the middle of the attempted syn. I have windows 7 ultimate. Any ideas about what to do?
If the steps above do not resolve the issue, attempt to sync with iTunes while logged in as a new admin user. Follow these steps to create a new administrator user within Windows:
From the Start menu, choose Control Panel.
Open User Accounts.
Select Create a new account and follow the instructions to complete the account setup process.
Once the new account is created, choose Log Off from the Start menu.
Log in to the newly created user account.
If the error does occur in the new user account, the issue may be caused by content downloaded or created on the device, such as podcasts and voice memos. Removing content from the device may address the issue.
If the error does occur in the new user account, the issue may be caused by content downloaded or created on the device, such as podcasts and voice memos. Removing content from the device may address the issue.
If these steps do not work at all, I would suggest calling AppleCare at 1-800-275-2273 (assuming your iPad is stilll within support or has an AppleCare Protection Plan) and let them know you have already tried all troubleshooting steps per TS2830. -

I spent 6 hours last weekend with this installation problem and came up with a process that seems to work - I've posted it a number of times and no one has said it failed for them. Lots of people have said it worked.
First go to Control Panel, Add or Remove Programs and uninstall Quicktime and iTunes.
Next go to the Microsoft web site below and download the Windows Installer Cleanup Utility. Install it, run it, then uninstall Quicktime and iTunes with it, if they appear in the list.

Go to apple.com and download the iTunes setup to your hard drive.
It doesn't hurt to disable or pause your virus scanner before installing, just remember to enable it again when you're done.
Try installing iTunes. You might still have problems installing iTunes because of QuickTime registry key access errors. If that happens, go to the link below, scroll about half way down and CAREFULLY follow the steps to change both Owner and Permissions on the keys that fail.

NEVER DELETE REGISTRY KEYS MANUALLY USING REGEDIT!
If this doesn't work, please re-post your problems. The more information we have to work with, the better we can understand the flawed installation process apple uses for iTunes and Quicktime and we can come up with solutions. It seems that the install problems are really with Quicktime rather than iTunes. -
Hi
My daughter has a apple mac laptop. It is coming up with a white page with a file picture with a ? mark in the middle of it. It keeps flashing. Nothing will work now and we car'nt seem to work it out. Does anyone have any answers ?That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Just press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead. -
Where is the "Scrollable Frame" on the Overlay Creator panel?
I can't seem to find the "Scrollable Frame" on my Overlay Creator panel and now I'm caught in the middle. Is there anything that I missed? I can only see the following:
Hyperlink
Slideshow
Image Sequence
Audio & Video
Panorama
Web Content
Pan & Zoom.I know you mean the other Bob, but the purpose of that is to have something to align with the edge of the scrollable content.
Without the dummy content you wouldn’t be able to position the content. Try doing it without that and you’ll see the problem.
