JTree truncating entries (pictures) - help?

I have written a Jabber client in Java, and am using a JTree to represent the buddies in the buddy list. The JTree dynamically removes and adds nodes as people sign on.
This JTree is placed in a JScrollPane in case the JTree gets to big or wide.
Every once in a while, someone will sign on (usually the first person that signs on), and the JLabel that represents the node is truncated with elipses (you can see what I mean by looking at this picture: http://linuxhelp.homeunix.com/JTree.png - I've circled the offending entry in red).
How can I fix this?
Thanks,
Adam

Hi,
I still have the same problem.
I use my own XXTreeModel that is derived from the DefaultTreeModel. It does not override any method from DefaultTreeModel but adds some convenience methods to add and remove nodes. These methods use the methods of the DefaultTreeModel.
I tried to use JTree.setRowHeight(0) and also added some nodeChanged(..) calls. But it doesn't fix the problem completely. Its getting better but it doesn't disappear.
Maybe it has something to do with the fact that I add about 100 nodes very fast.
Does anyone have another idea what to do?
Thanks
Ulrich

So I cannot scan my pictures, help. Windows 8.1 with HP Officejet 6500A Plus printer. Scanner works with other programs in my PC. Problem is PS12

I bought the Officejet 6500A Plus about one month and have experienced the very same problem. I tried to remedy this problem following suggestions in a number of different posts (static IP, router, firewalls etc), all to no avail. Last week I called support. The support I received by the tech over several hours and different days for a week was very good. However none of his suggestions corrected the connection issue. After today's recommended fix failed, he advised HP is aware of this issue with the 6500 and other affected printers. He claimed HP was working on a firmware upgrade. He did not know when the update would be provided. The tech also claimed HP acknowledged this problem in a written announcement. He agreed to email the announcement to me. I haven't received it. This has been the only problem I've had with the 6500

ICloud Address Book and Calendar not syncing. Missing and duplicate entries. Help.

I have duplicate entries in Address Book. I have missing entries on other devices. For calendar it just doesn't sync.
What I've done to try to fix it:
1) I signed out of all my devices from iCloud and MobileMe.
2) I then deleted all the the cache files in Library and any iCloud folders I could
3) I deleted all the address book and calendar entries on each device.
4) Went back and deleted anything in Library and caches.
5) I looked at iClould.com and confirmed they had entries in Address Book and Calendar.
6) Signed back into iCloud on each device.
7) All the devices then began to populate.
Trouble began:
1) Some Address Book entries are missing on devices.
2) iClould has multiple entries for the very missing contacts! All cutting off the notes field at different places!
3) It won't sync the missing contacts present on iCloud but not the device.
Help.

Solved it myself. What I did:
1) I have four Lion OS and two iOS devices.
2) I kept one computer with the complete address book I wanted to start with but disconnecting it from iCloud's Contact sync via Apple Menu > System Preferences > iCloud uncheck Contact Sync
3) Logged into iCloud.com and deleted all the contacts and groups manually ( many keyboard shortcuts worked )
4) On the main computer, using textedit, I replaced semicolons I was using to delimit items in the notes field with backslashes.
5) Once I confirmed all the other computers and devices had no entries in Address Book, on the main computer I turned back on iCloud Contact syncing. It worked. Correct count of entries and no more breaking notes at the semicolons!
6) Immediately all the other iCloud computers and devices updated to the correct notes! Finally.

IWeb is losing my pictures-Help!

I had some big problems with iWeb '06. I had a nice blog with about 20 entries in it, published to .Mac. On the blog pages, I would insert inline pictures imported from iPhoto. iWeb apparently doesn't like it if you put too many pictures on a blog page, and after a couple of posts with 20 or so pictures, iWeb would randomly delete the pictures from the blog, leaving just a placeholder where the picture used to be. So, I stopped putting pictures in the blog, but the damage was done. My blog was hopelessly messed up.
So, I upgraded to iWeb '08, and started from scratch. I deleted the old domain file, and made a new one. I wanted to keep the pages clean, so I am not adding any extra pictures to the blog. Instead, I am using photo pages and an album page to keep them organized.
So, now I have 8 albums with anywhere from 15 - 50 pictures in each. Total of about 300 pictures spread across all the albums. HERE IS MY PROBLEM - When editing the Albums page in iWeb, I get the spinning beach ball of death. After a while, it goes away, as do the pictures in the display on the albums page (they are still in the photo page, but gone from the album page), leaving a black space where there should be an area to skim through pictures.
My domain file is about 130 MB. I'm on a MacBook Pro, 17", 2.33 Ghz, with 2GB of RAM.
I'm afraid to add any more pictures, lest this on gets messed up like the last one. Any ideas?

I ended up reinstalling iLife '06 again, and then ultimately getting a new internal hard drive b/c ours was corrupted. But I am really kicking myself b/c while I published to a folder to "backup" I did apparently did not save the Domain file before we got the new HD. So I have a lovely copy of my iWeb site in a folder on my desktop that I can't use, b/c I don't have the domain file. So now I rebuild...
So essentially I don't have an answer to this problem at all, except if you reinstall iWeb, and use your Domain file to open your site, that may work. Soooo frustrating.

Lost Pictures, Help!!

I cannot find any pictures after May 2012 on my external hard drive even though I did a COMPLETE back up in Feb. 2013. Where can I find my pictures on the external hard drive?
I went to Users > "MaW1028" > Pictures > Right Click on Iphoto to show package contents
However all I found were folders from 1999-2012. I really need these pictures back!!
Any ideas?
Thank you

I'm happy to help out a user who's so good keeping good backups. Not everyone is as smart as you.
Instead of using iPhoto, see if you can perform a Spotlight search (command-space), and see if you can locate pictures you know should be there; i.e., look for familiar image names that might lead you to your lost photos. Also, in iPhoto, see if you can find the photos in the Trash. I'm presumimg that the recent photos might still be on your computer's HD, somewhere.
In Time Machine and even CarbonCopyCloner, you still might be able to retrieve your photos.

OK, let's try these................
1 - Boot up from your install DVD and run "Repair Disk" from the Utility menu. When done, restart back to your desktop, repair permissions and restart your computer. Re-connect your printer.
2 - Download & install the Gimp drivers. Make sure the one you install is compatible w/your OS-Gutenprint 5.2.8-pre1. Repair permissions, restart your computer & re-connect your printer when done.
The Epson model I have, in order to get it to print wirelessly, I had to install a Gimp driver.
3 - Check out the following KB Articles:
Mac OS X 10.4 Help: Connecting to a network printer
Epson Printer Drivers v2.10 OS X
Adding a printer to your printer list in Mac OS X
Mac OS X 10.4 Help: The printer I'm adding says "Driver not installed"
======================
If still unsuccessful after trying all of the above, the problem could be your iBook or human error. You can either call Epson & ask to speak with a Mac savy supervisor or return the printer & find another that is compatible w/your current OS.

The lost pictures. help please!

I got a new iphone last week and I set up an icloud account on my old iphone to make sure I would have all of my pictures on my new iphone. Now I set up my new iphone and none of my pictures are there. Is there any way I can get those pictures back? Or is there anyway I can find them. Any help would be amazing!

Move the photos from the Trash bin in iPhoto onto the Library icon to get them back in their proper events. Then check the thumbnails to see if they are still behaving the same. If they are make a temporary, backup copy (select the library and type Command+D) and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with Option #1, followed by #3 and then #4 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Trying to put a photo in a project and after dragging in, it's a different picture-help!

I'm trying to drag photo's into a project...it was all working fine and then all of a sudden, I drag something in...and it's a different picture, over and over! I've shut down, logged out...still not working.

Table entries transport help

Hi friends,
I need to transport a selected entry from a table. how can i do that. could somebody help me.
Thanks,
Kiran

Go to SE10.
Click on the 'Create' icon.
Select 'Workbench Request'(assuming your table is not customizing table).
Enter description and click 'Save'.
Put cursor on the task (lower number of the two) and in menu, 'Request/task>Change Type>Development/correction'.
With cursor on the task(lower number), click 'Object List' icon on the toolbar.
Once in, you need to toggle to 'Change' mode using the pencil icon.
Then click on 'New Entries'. Now add the R3TR, TABU, <ZTAB> in the first row.
Again in the menu, select 'Extras>Change object function>Key according to key list'.
Now go to the menu, 'Goto-->Key list'. In the subsequent screen, click on 'Insert line' icon(with a + sign).
Click on 'Key fields' button and it will now allow you to enter the values for each key field.
Hope this is clear.

JTree not Updating - please help

I am totally perplexed.
I created a pretty standard implmentation of a JTree, utilizing the DefaultTreeModel, DefaultMutableTreeNodes, etc. The JTree is contained in a JScrollPane. The tree displays a string value that is one of the properties of the UserObject of the node, for which purpose I created my own subclass renderer and an editor. A JButton causes a new node to be added to the root node. All was working fine, until...
I put the JTree and the TreeModel in a new class, along with the method to populate it. I created a method that passes a handle to the JTree ("getTree()") which I use to instantiate the JScrollPane ("new JScrollPane(tree)"). Now when I add a node to the root, it doesn't display!
I have tried "tree.revalidate()", "tree.updateUI()", "scrollpane.revalidate()", "tree.repaint()", "dialog.repaint()" all to no avail. If I close the dialog and reopen it, everything displays fine.
Can anyone tell me what I'm doing wrong?
Thanks very much...

Here are the two classes. Your help is greatly appreciated.
