DocumentListener #removeUpdate -- Retrieving the removed text

Hi,
I have a DocumentListener registered on a Document. I not only want to know when text is removed, but I want to know what text was removed. It appears to me that the document structure is updated before the listeners are notified (even though sticky positions aren't ...?), meaning the offset/length methods will not work for my needs.
Is this correct? If so, how would one retrieve the removed text?
I don't want to override #insertString(int, String, AttributeSet) nor #remove(int, int) because these apparently aren't called when UndoableEvents from the document are undone/redone. It's been my experience that only DocumentListener methods are called universally (that is, for undo/redo and normal user operations).
Passing the line associated with the offset into DocumentEvent#getChange(Element) gives null. Aside, even if it did return something, what concrete implementation of Element represents a character in the document? Or, what is the lowest level of the hierarchy -- line or character?
Thanks in advance,
Brien

Thanks for the references.
As for casting the event to a CompoundEdit, it is definitely doable, but how would I use the CompundEdit? It's unfortunate that many classes in the java.swing.text package aren't designed to be flexible for different uses. It seems the two members that would be useful, #lastEdit and #edits, are protected.
Even if I could get the UndoableEdit, like GapContent.RemoveUndo, how would I get to the internal String representing the removed text?
I could really use the details on this.
I see two options if I want to pursue this further --
1. Use reflection to access the protected fields (super bad).
2. To get what I want, I could, in the removeUpdate method, temporarily undo the event, check the document, then redo the event. This seems very sloppy, wasteful, and the implementation would have to be very careful with the infinite mutual recursion.
As it stands, I likely won't pursue it. It's not very critical, but it's very disappointing.

How to retrieve the long texts from purchase Info record (ME13)

Hi,
How do I retrieve the long texts data from the tab, Texts of the Purchase Info record(ME13). I want to retrieve the current long texts data(long text1, long text2 long text3, long text4) for a given purchase info record. These long texts points to the structure BRM06I.
So, now how do I fetch the data from the structure BRM06I. Is there any function module for the same..
Thanks.

Hello,
Texts are stored in tables STXH & STXL (header and item). You can search these tables by selecting Text object = EINA and Text name = Info Rec #. The text ID's you will see are the ID for various texts maintained.

Problem with retrieve the chinese text from oracle DB

my running enviroment is
Linux 6.0+ apache Jserv+java 1.1+oracle 8.05
my db character set is zhs16cgb231280.
when i retrieve the chinese text using servlet and forward to client browser. it doesnt display the text property.but if i transfer the data to an Applet. it will be ok.
my knowledge is oracle using unicode to communicate between db and JDBC.
So i dont know how to solve my problme.
Who can help me?
Thanks Advanced

Hello,
What's the charset of your database? Mine is AMERICAN_AMERICA.UTF8
In this case, I could successfully insert and retrieve the Chinese characters without any encoding parameter in the getString() method. Perhaps you could try it.

Enhacement for removing case sensitive of the short text entered in Me21n

Hi very one ,
i want to write a enhancement to remove the case sensitive of the short text entered in me21n transaction code for service Number . ie .. whether i enter the text in captain letter or small letters it should fetch the exact data accordingly to the short text entered ( the respective service number should be retrieved ) , i think there will be some function module that will remove this case sensitive thing . plz help me out
Regards
Syed Akbar

Thank you, Kappy, for your quick and helpful reply to my (admittedly) not very quick question!
It strikes me as odd that Apple would appear to make the use of both lower- and upper-case letters possible in the short user-name, leaving the possibility that upper-case letters might lead to some problems/conflicts down the line. It would be helpful if they'd provide some explanation about this. Anyway, as I said, I'm very far from being an expert in all this, and appreciate that people like yourself on these
forums are willing to provide helpful feedback.
Best regards,
Stephen

How can I remove the 'Qty' text from individual product descriptions?

I didn't know if this was possible or not... I've recently taken the reins of handling an ecommerce site that had been published before I got on board. My boss wants me to remove the 'Qty:' description from some products because the image shown for some products is a misleading description of the actual quantity available (i.e. there is a picture that shows a stack of conveyors parts, and it says 'Qty: 1' to represent one 'stack' of conveyor parts - this confuses customers into thinking there's only one individual conveyor part available however). To avoid any confusion he requested that I remove the 'Qty' text from similar images. I see that you can change the 'In Stock' amount of a particular product underneath the 'Inventory' tab of the 'Products' menu, but I didn't know if it was possible just to remove the quantity description altogether without just typing the quantity in at zero. This is likely a strange question but I didn't know where else to ask! I would appreciate any help or advice Thank you

Hi ewhelhalu,
I just figured out a way to do it, but it's a little weird and complex, and I have no idea what the consequences for editing this .plist string might be. I'm thinking it'll be OK, but you never know what might happen when you screw around with Apple's intentions.
So if you have the Developer Tools on your install of OS X, you can use the Property List Editor to edit the Dock files. (If you don't have this program, you can use a program like [Pacifist|http://www.charlessoft.com> to selectively install stuff from your Leopard disk).
The file you're interested in is within Macintosh HD > Users > Your Username > Library > Preferences, and it's called com.apple.dock.plist. Open that up with Property List Editor, and open the arrow drop-down next to "Root." The lines you're looking for are "persistent-apps" (the left side of your Dock) and "persistent-others" (the right side). If you open the drop-down arrows, you'll see there are numbers below each. The numbers correspond to your Dock items, from left to right.
If you click on drop-arrows by the numbers, a sample hierarchy looks like this: 0 > tile-data > file-label. It's the "file-label" string that you want to edit. Just make it ("it" being the name of the icon under the "value" column) blank, save the file, go into Terminal and type "killall Dock" without the quotes, and your Dock icon should appear without a name. You'll have to do this for all of them.
I should insert the usual caveats here about backing up beforehand and making sure that you have a copy of the .plist file before you start tweaking it so that you can replace it if things go wrong. And perhaps someone with more knowledge of Terminal or third-party apps than I have will come along and suggest a simpler solution. But that's the only one I have.
Hope that helps!

In keynote - Leather Book theme - is there a way to remove the artwork in the middle of the cover page (between the two text boxes) (the squiggly thing)??

I am trying to create a poster - in Keynote - transferring it to PDF then to JPEG so I can print it - and while I like the background in this Keynote theme (leather book) I can't seem to remove the artwork that is positioned between the two text boxes. Does anyone know how??? Can it even be done?

I somehow ended up on creating a new master slide. I can FINALLY access the artwork - it has a box around it of x's - but I can't seem to do anything. Delete doesn't work. Trying to shrink the box doesn't work. I'm not getting a dialog box when I click on it that is specific to the x'ed area. It pertains to the full background page. I'm obviously missing something - the fact that I have never been in Keynote before may have something to do with it! :-)

I recently removed an outlook account and now all of my calendar events are missing. The majority of them were added from my iphone 4s. How do I retrieve the events? Backing up with iCloud did not help, as I assumed it would.

I recently removed an outlook account and now all of my calendar events are missing. The majority of them were added from my iphone 4s. How do I retrieve the events? Backing up with iCloud did not help, as I assumed it would.

Outlook is a mail client for PC's (and Macs). It is not a type of account. Do you mean an "Exchange Account"?
If so, then re-add it. The calendar events live on the Exchange Server. The only way to get them back is to re-add the account to the phone. The contents of Exchange and IMAP accounts are not part of the 'backup' as they already exist elsewhere.

How to retrieve the 'Where Clause' text?

Hello all,
I have created a package to retrieve all the DML's executed against the database for the day, for a particular user. DBMS_LOGMNR package was used to retrieve DMLs. But the DMLs retrieved have their 'WHERE' clause text converted to ROWID's. I need to find out the 'WHERE' clause with the parameters.
I tried retrieving values from the v$sql views, but that information is cryptic and very volatile.
Is there a way to retrieve the 'Where' clause? If not, is there a way to retrieve the 'WHERE' clause information using a trigger against the corresponding table.
I am desparately lookin'for a solution. Hope someone out there can help me out.
Regards,
Prabu Raghav.

Hi Andrew,

Any suggestions?

You already tested in Firefox's Safe Mode and that did not make any difference?
Can you associate this problem with any software changes, such as upgrading from Firefox 31 to Firefox 32, or updating an add-on, or Windows, etc.?
Have you noticed problems with any other dialogs or menus?
Occasionally a corrupted settings file may cause issues with dialogs. This file also stores toolbar customizations. You can rename the file and customize from scratch.
Open your current Firefox settings (AKA Firefox profile) folder using either
* "3-bar" menu button > "?" button > Troubleshooting Information
* (menu bar) Help > Troubleshooting Information
* type or paste about:support in the address bar and press Enter
In the first table on the page, click the "Show Folder" button
Leaving that window open, switch back to Firefox and Exit, either:
* "3-bar" menu button > "power" button
* (menu bar) File > Exit
Pause while Firefox finishes its cleanup, then rename '''localstore.rdf''' to something like localstore.old
Start Firefox back up again. Any improvement in the Edit Bookmarks dialog?
