Statusbar displaying current line number?

Hi,
I am building a swing application where I have one text editor and one status bar. I want to display current line no in status bar. I tried with getCaretPosition() but it does not returns line number, is there any other way to get current line number to display it on status bar? Thanks.

is there any other way to get current line number Did you search the forum?
How about the keywords "current line number", taken directly from your question. So you can see its really not that hard to think of keywords to use in a search.

Current line number in smartform

Hi All,
          I need to know is there anyway that i can know the current line number in smartforms.
My requirement is:
   I have 1 header item and its 3 line items, if there is no space in main area to display all the header and its line items , then it sould be printed in next page,
Eg:                          PAGE 1
HD       Line
A           01
             02
             03
B           01
             02
             03                       PAGE 2.
          if this is the case then whole B 01-03 should be printed in next page.

How to find dynamically the current line number in the source file

Is there a mechanism like __LINE__ and __FILE__ macro in C to get dynamically
the current line number and file name of a source file?

Don't know - but others have asked too. Have you searched the forum? For example:

How to read current line number in function module sourrce code?

Hi All,
How to read current line number in function module sourrce code?

If you have new editor you would be able to see the line number.
Or in the Dump screen - there is a button called Debugger - click that you would be able to see the code where dump has occured.. you would be able to find the line number from there.
To get the new editor with line number , you need to change the settingsin SE38.

2.1 EA2: is it possible to pass current line number to external tool

When I define external tools (in Tools / External Tools...) I can pass current file name and directory to my external program.
Is it also possible to pass current line number (where is my cursor in open file) to external program as a parameter?
If not then it would be a feature request from me :)
And also - is it possible to develop SQL Developer extensions for syntax color coding of other file types (meaning other than PL/SQL files)?

raymonds,
For line numbers, we cannot do it at the moment as it is not exposed in that API, however, you can request it on http://sqldeveloper.oracle.com at the feature request station
For color coding for another language, you can develop a hilighting plugin, but we do not have an easy way of associating the plugin with an editor for a specific file type. Again this would be a feature request.
Remember, all these get evaluated each month and assigned into Enhancements for the tool. If enough folks vote for the feature, it is highly likely it will appear.

SapScript, How do I read the current line number?

I have sections of text - each in it's own element with an 'include' of the standard text.
These sections are variable in size.
All elements are in the MAIN window.
I do not want a paragraph to split over two pages.
How do I read the current line number within the sapscript before the section prints so I can issue a new-page command at the beginning of the paragraph?
Thanks!

Yes, that does work for paragraphs.
If I have multiple elements to print from within a loop where "at first, at each and at last" each call the Sapscript funtcion write_form - how can I keep the whole section together. protect/endprotect will keep each element together but not the group of elements.
There must be a way to find the current line number.

Why jdb can't display the line number?

Hi,
I use jdb to debug HelloWorld.java run on cldc_hi. Where cldc_hi is build ENABLE_JAVA_DEBUGGER=true
I compile HelloWorld.java with -g
And use the same java version when compile and launch
In jdb I input
stop in HelloWorld.main
run
step ...
jdb shows�F
Step completed: Thread1[1] thread="Thread1", java.lang.Class.initialize(), line=-1, bci=180
what cause line gives -1 ?
Thanks very much for any suggestions

I would suggest trying the debugger in eclipse.
This displays each line graphically.

Updating the Line number on status bar.

Hi all,
I have developed an editor using swing, however I have used the JTextpane class to display the text. I had did of trouble with features such as go to line as this class does not support methods such as getLineCount in the JTextArea class. However I over came this by writing the method shown below.
The problem is that I want to show the current line number on the status bar. When do I call this method? After every '\n'?
The setLine Number method is below.
Thanks for your help
Ciara
public void setLineNumber(int num) {
int lineNum = 1;
int lastNewline = 0;
char text[] = editor.getText().toCharArray();
if (num < 1)
return;
if (num == 1) {
editor.setCaretPosition(0);
return;
int i;
for (i = 0; i < text.length; i++) {
     if (text[i] == '\n') {
     lastNewline = i;
     lineNum++;
     if (num == lineNum) {
     editor.requestFocus();
     editor.setCaretPosition(lastNewline + 1);
     return;
}

Perhaps extending a PlainDocument is better, if line
numbers are meaningful for your application.
About your method, mind that getText can be quite dear,
so it is better not to call it if you don't need it.
For a more efficient alternative, look at Document.getText(int offset, int length, Segment txt)It uses a Segment (un unguarded string) pointing directly
into the document, which you can use much like a char
array.
As to your question, I would define a CaretListener
so as to update the status bar when the caret moves.

Re: Method name and/or line number available from withinForte?

To my knowledge there is no such capability with forte, and for sure it
would be nice. Short
of storing all that metadata at runtime, a compile-time substitution such
as is done with
most C preprocessors would work as well.
However, I believe the solution you've identified falls short in a deployed
fashion - I think
all that method name/line number stuff is only available from the workshop...

I'm sure you all know what I'm getting at by now -- when raising your own
custom exceptions or logging messages we'd like to be able to not hard-code
method names and line numbers into them. I know these are available with
log flags so this information is stored somewhere -- is there an API to
access it on an agent, the task, or the environment? The only way I can
think of doing this (which is not-so-elegant) is to force a Forte exception
to be raised (like access a method on a null TextData or something), then
immediately catch it and extract the method and line number from it. Is
there a more elegant way?

Method task.TraceBack () returns a string suitable for shoving on the error
stack, and representing a call trace. The method
method TomW_RaiseException.RaiseException
begin
ge : GenericException = New ();
ge.SetWithParams (SP_ER_USER, task.TraceBack ());
task.ErrorMgr.AddError (ge);
Raise ge;
end method;
produces the following when called from the display method of the window in
which it is embedded.

I suppose that a sufficiently determined person could parse the results of

the name of the calling method.

How to get line number in JAVA code?

Hi,
What method can I use to return the current line number of my coding?
Assuming I'm at line 10 and I want to do something like System.out.println("I am at line number " + ????);What method should I use to get "10"?
Please advise.
Thank you.

If you run Java in Dos prompt, a new line of result is displayed at bottom and the screen scroll. There is no line number in that way. Other language like C have something like that.
If you use Java Swing, you can display with x, y coordinate option but it is graphic mode.

JEditorPane - getting Selected Text or Active Line number

Is there any predefined method that will give me the current line selected or the line at which the cursor is?
I am displayed a piece of java code in my JEditorPane, the user can browse through the entire file.. and I need to call an event when a user selects/double clicks a particular module name or based on the current line number where the cursor is. Is there any simple technique to get the line number or the current highlighted text?
I am relatively new to JEditorPane. Also If you think I shoudl go upon writing an actionListener, a mouse of keyboard... please let me know how to go about it. I keep getting confused.
Thanks,
Sirish

In the future, Swing related questions should be posted in the Swing forum.
there any simple technique to get the line number Well, a JEditorPane is typically used for displaying HTML. So does a line number make sense when you don't know the contents of the HTML. If you simply have lines of text then you should be using a JTextArea or a JTextPane.
Check out this posting for a method to return the line number at a give caret postion:
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=608220
or the current highlighted text?Read the API. A get??? method will do what you want.

How to get input source line number

I wrote a XSLT transformation that checks the input XML for errors.
When the transformer finds a problem, it can terminate with <xsl:message terminate="yes">, which outputs the line number within the transformer XML source. I do so in my implementation to indicate errors.
But i need to output the line number of the input source, not that of the transformer source, because this is the location of the error.
Anybody knows how to do this?
How can i get the current line number of the input source XML text?

Hello Fritz!
XALAN reads the entire input file (SAX) before starting with transformation.
So overriding the input stream is no way to find this line number.
I think this would have to be a built-in XSLT functionality within the tag "xsl:message".

Line number in a stored procedure

Hello All,
In a stored procedure, as a part of logging the debugging information, I want to store the current line number in a variable (say line_number) and return it from the stored procedure as a output paramater. I would like to update line_number with the current line number in the stored procedure code at certain intervals. This would help me to know till where the procedure executed in case of failure.
Now my question is as follows:
Is there any standard variable in Oracle which gives the current line number in the stored procedure?
Please see the example code below
CREATE OR REPLACE PROCEDURE XXXXX
(line_number OUT NUMBER)
AS
line_number = <current line number in the code>
line_number = <current line number in the code>
line_number = <current line number in the code>
EXCEPTION
WHEN OTHERS THEN
BEGIN
ROLLBACK;
END;
END XXXXX;
Best Regards,
Ramesh

Hi,
No, is not. Try to use all_source for this.

Line number in Classical Report

Hi All,
How to get current line number in Classical Report?
i want to show that in my o/p.
regards,
Anuj

Hi Anuj
Please try like this
there are 2 ways.
READ CURRENT LINE FIELD VALUE <fieldname>.
READ CURRENT LINE.
first statement does'nt work on numeric type fields especially when there are commas ',' like 5,600,00.
it'll give you dump.
but always works on CHAR type.
so in your case use second statement. though you're reading entire row but use only single field what ever you want.
check this example.
DATA : BEGIN OF itab OCCURS 0,
matnr LIKE eban-matnr,
menge LIKE eban-menge,
END OF itab.
AT LINE-SELECTION.
READ CURRENT LINE.
WRITE :/ itab-menge.
START-OF-SELECTION.
SELECT matnr menge INTO TABLE itab FROM eban UP TO
10 ROWS WHERE matnr NE space.
LOOP AT itab.
WRITE :/ itab-matnr, itab-menge.
HIDE : itab-matnr, itab-menge.
ENDLOOP.
Thanks

Thanks Andra,
The problem is the multiple invoices is for non goods receipt item so there will be no delivery.At the time of creating a PO the GR is not checked so there will be no delivery .
Also this setting is for invoices which are comming from Vendors.But if we are genrating the invoices manually it is not blocking those invoices.Also i there is nowhere mentioned in Incomming invoice to set tolerence for incomming invoice.Are you talking about Vendor tolerences?
Thanks in advance
