How to create a single line textbox with up-down button?

Hello,
I mean for example is a text box for percentage. You can type in the value, or click the up or down button to get the value you desire. I tried attaching a small-sized vertical JScrollBar to a JTextField, but it is getting complicated that I need 2 different listeners(AdjustmentListener & FocusListener) for this.
If you have done this before, or maybe you have some suggestions, I would appreciate the help. These are some conditions that the percent text box needs:
- a click on up/down button increase/decrease the value by 1.
- the user types in a value more than 100 or less than 0 and press one of the button(up/down), setText to 100 or 0.
- the user types in a value in range, increase/decrease that value when up/down button is clicked.
Thank you for your time.

That's called a "spinner". I understand that it's a standard component in SDK 1.4, but I haven't looked at that myself, it's still in its beta stages. If you go to this page:
http://www.toedter.com/en/jcalendar.html
you will see an example (JSpinField), and you can download it for your own use.

Asset Creation in PR and PO and MIGO as a single Line item with "N" qty

Hi All,
In Purchase requestion ME51N
Now we are creating "n" number of assets ( All are same item but "s.no" will vary) with "n" number of line item.
Instead of this I have to enhance to create only one line item( For same item) with "n" quantity.
for the ASSET account Assignment we have to create Asset(Temp no) for the each item/quantity(if the same item).
as well as if they are going to create a PO with ref to PR they have to see all the "n" number of asset no.
In MIGO creation for each asset we have to assign S.No and Asset Tag.
How enhance the functionality in PR,PO and MIGO as well as in Invoice.
Is it any User Exit/BADI is available for PR/POand MIGO to show all the "n" number of assets for a single line item.
Kindly help me to give details to proceed further.
Thanks in advance.

Hi Sharma,
What i understand from your question is, you want to create a single line item in PR and PO. But the qty would be > 1.
Each single qty would have its own asset number in account asssignment tab of item details of PR & PO.
This is what you are expecting...Right???????????????
Then this is possible with certain limitations.
While creating PR, enter only one item with more qty.
In item details section, in account assignment tab, on top left corner, there will be a button called Multiple account assignments.
Click on it, then it looks like a table, where you can enter more than one line. (each line will have its own asset no)
And choose option Distribute on qty basis for field Distribution.
So that you can enter 1 qty for each line. ( Ex: if you created one line item in the item level with 10 qty, you need to maintain 10 line here, each qith 1 qty and diff asset no).
The only limitation to this is, the GRN would be treated as non valueted. So when you make GRN there wwould not be any accounting doc. ( means no use of GR/IR clearing account as like normal for POs)
when you prepare MIRO, all the assets will be capitalised and vendor credited.
But in case if you receive partial invoice, then you have choose manually in MIRO. which asset is ot be capitalised.
After entering the PO number in MIRO, there will be one line will be appeared with full qty. in the same line, move till the end of line, there you will have one button called Account assignments.
Choose and go there, here you can choose which individual asset line to be considired.
This will resolve your issue.
Thanks,
Srinu

Hope someone could help me.

There are two ways of doing it, depending on what you want to accomplish. Both require that you edit the file ~/.bashrc (I assume you use bash)
1) If the application places all the executable files in a given directory (let's say /opt/Application/bin/), you can access all those executables directly by simply telling your shell where to look (in the same way the shell automatically looks for executable files in eg. /usr/bin). In ~/.bashrc, you would have to add a line that looks like this:
PATH="$PATH:/opt/Application/bin"
2) If you just want to make a traditional "shortcut" that executes a given command, this can be done with alias. Add this command to your ~/.bashrc:
alias shortcut="some command"
In this case, typing shortcut into a terminal will be interpreted just like if you had typed some command instead.
In order to try out these changes, either restart your terminal or run this command:
source ~/.bashrc
[EDIT]
I was obviously beaten to it

How to create a muli line text area using JavaFx

Hi all,
Since the preview SDK does not contain TextArea any more, I am wondering how to create a muli line text area using JavaFX. The behaviour of this text area/field should be somehow similar to JTextArea in Swing or StyledTextWidget in SWT.
Does JavaFX have any support for this? What would be a sensible approach to create such a widget?
Thanks for your suggestions,
br michael

This is a pretty old thread (I know I came across this while searching for something similar recently), but I figured I'd throw this out there in case other people might find this useful. As I write this, JavaFX's latest version is 1.3... which may have added the needed functionality since the last post.
You can now create a multi-line text area using a TextBox and by specifying the nubmer of lines and setting the "multiline" value to true. It may not offer all of the same functionality as JTextArea, but it did the job for what I needed... newlines by pressing enter, scrollbar if text surpasses height, etc.
Here's a simple example:
Group {
   content: [
      TextBox {
         text: "This is a multi-line textbox"
         lines: 10 // <-- this may/may not be necessary depending on your situation. Default is 5.
         multiline: true

How to create a single report using 5 difftent reports

Please suggest me.

Use Analysis Process Designer (RSANWB) to feed each of the survey BEX reports to one DSO. Assuming each of the surveys has something in common to compare. Could also be used as a snapshot storage for the surveys in case history needs to be compared/archived.
Build the Direct update DSO with the survey objects. Add needed time characteristics and/or version control objects to the key.
Data sources will be the 5 surveys.
Add formula to hardcode version/time for history.
Data target is the direct update DSO.

How to create a multi-line table/column comment

Can someone tell me how to create a multi-line table or column comment?
Apparently, the concatenate operator (||) does not work with the COMMENT statement.
I've searched the Oracle manuals and couldn't find an answer.
COMMENT ON TABLE sometbl IS 'i would like to break up this comment into several lines in order to improve readability'; Effectively, this is what I'd like to do (but it doesn't work):
COMMENT ON TABLE sometbl IS
'i would like to break up ' || CHAR(10) ||
'this comment into several lines ' || CHAR(10) ||
'in order to improve readability' || CHAR(10); Oracle version is 10.2.0.4

Why not just
SQL> create table t (a int)
Createtable successfully completed.
SQL> comment on table t is 'i would like to break up
this comment into several lines
in order to improve readability'
Commenton successfully completed.
SQL> select * from user_tab_comments where table_name = 'T'
TABLE_NAME           TABLE_TYPE COMMENTS
T                    TABLE       i would like to break up
                                 this comment into several lines
                                 in order to improve readability

How to create a single 'not null ' validation for all the items in a page ?

Hi everyone ,
how to create a single 'not null ' validation for all the items in a page ? I have many textfields . Instead of creating 'not null' validation for each item , I would like to create a a single validation control that will serve the purpose
Thanks & Regards

bob , as u said I have done the following :

2) under delete button , there is 1 item and have set Required to 'Yes' for the item
3) defined page validation for 9 items under 'create ' button and have set it to fire when 'create ' button clicked
4) defined page validation for 1 item under 'delete ' button and have set it to fire when 'delete ' button clicked
now , when I click 'create' button it even shows for the item under 'Delete ' button that it is a required itemSorry, I didn't see this note. The required template won't work, there is no way to attach it to the button.
The best solution is as the reply a couple replies up
Create 2 page type validations as a PL/SQL with code
1st validation
:P1_ITEM1 IS NOT NULL and :P1_ITEM2 IS NOT NULL ...... and :P1_ITEM9 IS NOT NULL include all 9 items
Set the When Button Pressed to the CREATE button
2nd validation
:P1_ITEM10 IS NOT NULL
Set the When Button Pressed to the DELETE buttonI think that's going to be the easiest way to do it.

How to create a stroked line that randomize each stroke color?

Hi all, I am strating out designing in illustrator and I need help on how to created a stroked line, -----------, with each stroke ( - ) a different colour, like, each stroke having a different randomized color which differs from the next one.
Also, I need help on how to mask out parts of a template given to me by my school so i dont infringe that boundary when I add my lines to it. All helps appreciated, thank you.

Ok thank you for your responses, Monika, I followed your instruction but it isnt working, is there any steps that I might have done wrongly? Here are some screenshots that depicts my problem:
Here it is after I outline the stroke,
And here it is when I apply the script:
However, after I clicked okay, nothing changed and the strokes are still in their original color(yellow) as seen in the first picture. Did I do any steps wrong that result in this outcome? Also I've tried to put 99 instead of 99s and still, it didnt work.
