Goto row and column in a JTextArea

Does anybody here know the correct procedure to get to a specific row and column in a JTextArea? I want to be able to do something like this:
replace(char c, int row, int column) - where the original character at row,column will be replaced with c.
I know that in C++, there is a windows console library that lets u do this, but there isn't one in java so I'm trying to get around it using a JTextArea.
Thank you.
Any Help/Comments/Ideas will be greatly appreciated.

JTextArea has a replaceRange method.

Get current row and column in JEditorPane

Hi,
I have a JEditorPane and I want to show the current row and column according to the caret position
can anyone please assist ?
Thanks,
Dekel

JEditorPane was designed to display HTML which may not have a great concept of row column once you start adding tables and other fancy stuff. If you only have text data then I would use a JTextArea or JTextPane, they are easier to work with.

How do I keep account of line and column number within JTextArea?

How do I keep account of line and column number within JTextArea?
Thanks.

hi kamlesh,
to get the number of columns in a JTextArea u have the function
getColumns() which gives u the number of columns in the text area.
To get the number of rows present u have the function
getRowCount() which returns an int that specifies the number of rows in the text area.
Hope this helps

How can i open a PDF bank statement in numbers so that the rows and columns contain properly aligned data from statement?

how can i open a PDF bank statement in "numbers" so that the rows and columns contain properly aligned data from statement?

Numbers can store pdfs pages or clippings but does not directly open pdf files. To get the bank statement into Numbers as a table I would open the bank statment in Preview (or Skim) or some pdf viewer.
Then hold the option key while selecting a column of data.
Then copy
Then switch to numbers and paste the column into a table
Then repeat for the other columns in the pdf document
It would be easier (in my opinion) to download the QFX or CSV version from your bank

How to get number of rows and columns in a two dimensional array ?

Hello,
What would be the simplest way to get number of rows and columns in a two dimensional array represented as integers ?
I'm looking for another solution as For...Each loop in case of large arrays.

Hi Petri,
See a attached txt file for obtaining two arrays with upper and lower index values

How do I delete multiple rows and columns in an image?

I am looking into how digital SLRs extract video data from a CMOS sensor. To give an example, the GH1 from Panasonic can record video at 1920 x 1080 from a 12 MPixel sensor that, say, is 4000 horizontal x 3000 vertical. How they do that seems to be not in the public domain, but there have been a few guesses (see http://www.dvxuser.com/V6/showthread.php?t=206797 and http://luminous-landscape.com/forum/index.php?showtopic=38713).
One approach would be to simply read every second row of sensor pixels (1500 rows read from the original 3000) and once you have those in memory, delete every second column (2000 columns left). You would end up with a 2000 x 1500 image which could then be resampled to 1920 x 1080.
I'd like to simulate what the camera appears to be doing, by generating a 4000 x 3000 test image and then asking Photoshop CS4 to delete the appropriate rows and columns. It may not necessarily be every second row; the Canon 5DMk11 appears to read every third row, so I may need to delete two out of every three rows.
Can Photoshop do that sort of thing? If so, how?

Thanks for the suggestions. Yes, I did take a detailed look at your images, but they weren't 100% convincing because it wasn't clear just what was happening. And Adobe's explanation, after reading it again, explains nothing at all to someone who doesn't know how Nearest Neighbor works.
But you are correct -- Nearest Neighbor does effectively delete pixels. I proved it with the attached 6 x 6 image of coloured pixels (the tiny midget image right after this full stop -- you'll have to go to maximum zoom in PS to see it).
These are the steps to delete every second row and then every second column.
1. Select Image > Image Size.
2. Set Pixel Dimensions > Height to half the original (in this case set to 3 pixels).
3. Set Resample Image to Nearest Neighbor.
4. Click OK and the image shoould now consist of three vertical white strips and three vertical Green-Red-Blue stripes.
5. Repeat steps 1-4, but this time set Pixel Dimensions > Width to half the original (in this case set to 3 pixels). The image should now consist of three horizontal stripes Green-Red-Blue.
Just to make sure the method worked for every third pixel, I repeated the above steps but with 2 pixels instead of 3 and obtained the correct White-Green, White-Green pattern.
I resampled the Height and Width separately for the test so that I could see what was happening. In a real example, the height and width can be changed at the same time in the one step, achieving the same results as above.
Finally, how to explain how Nearest Neighbor works in the simple cases described above?
Division by 2
In the case of an exact division by two (pixels numbered from top leftmost pixel), only the even numbered rows and columns remain. To put it a different way, every odd numbered row and column are deleted.
Division by 3
Only rows and columns 2, 5, 8, 11... remain.
Division by N
Only rows and columns 2, 2+N, 2+2N, 2+3N... remain.
To put it simply, a resample using Nearest Neighbor (using an exact integer multiple) keeps every Nth row and column, starting from number two. The rest are deleted.

Lock rows and columns header in a table view report. It is possible?

hi,
I have a Dashboard that displays a report in "Table View" with many rows and columns.
Is it possible to set a lock on the rows and columns like Excel?
This would have blocked such headers that contain attributes and measures and to browse the report (eg with a scroll bar) had always viewed the headers.
Can you help me?
Thanks

Is it possible to switch the rows and columns?

Is it possible to switch the rows and columns of a table? The reason I ask is that it would be easier for me to input the data with the number at the top of a column and the fields going down. But it would be easier to read the data with the number on the left and the fields going to the right. Is it possible to switch a table in this way?

It sounds to me as though you wish to transpose a table so that the original is changed from rows to columns and from columns to rows, as in the following:
Table 1
 A B C
========
1 o p q
2 r s t
3 u v w
Table 2
 A B C
========
1 o r u
2 p s v
3 q t w
You are right - it would be nice to have a menu item to magically transpose a selected block of cells. But there isn't one. So...
One way to solve this is to use the index() and transpose() functions to accomplish row and column cell transposition. If you are going to use a 1:1 cell correspondence and change the header columns and rows also, you can use this:
 =INDEX(TRANSPOSE(Table # :: <range>),ROW(),COLUMN())
where Table # and <range> is substituted as in the following fashion:
 =INDEX(TRANSPOSE(Table 1 :: $A$1:$C$3),ROW(),COLUMN())
Create a second table. Copy the modified formula above with the appropriate substitutions, select the range you wish to have your transposition inserted into (must match the transposed cell dimensions of the original range), paste the forumula and voila! the cells will be transposed.
Cautions:
o The target table must match the swapped cell length and width dimension. For example, if the original data range is 6 columns wide by 4 rows deep, then the corresponding table or range to hold the transposition must be 4 columns wide by 6 rows deep.
o If your transposed data block is to be offset from the origin of the new table, then you will need to include a subtractive offset into your cell formula, since in the transpose() function the data in the master data range is referenced from its position with the master range, not its cell position in the table. Such an offset is necessary because this example formula uses the target row and column numbers to arrive at indexed positions.
For example, if the new data range is to be offset one column to the right and one row below from the target table's origin then you must subtract (-1) from the cell and from the column references in the formula:
 Example:
 =INDEX(TRANSPOSE(Table 3 :: $B$2:$D$4),ROW()-1,COLUMN()-1)
If someone has a better solution I'd be glad to hear of it.

Keeping row and column headers while scrolling inside a Web Dynpro table

Hi,
I have to display a 2x2 matrix with storage location names on the x-axis (i.e. as Column Headers) and material names on the y-axis (i.e. row headers). The table data represents the quantities of a particular material in a particular storage location.
I am using dynamic UI generation to create this table. It can contain as many as 150 columns and almost as many rows. I dont want a page level scrollbar, and hence, have placed my table inside a scroll container UI element with a fixed height and width.
I need a way to let the users use the scrollbars inside the scroll container, but still let them see the row and column headers. Is there a way that I can do this in Dynpro for Java?
Thanks,
Navneet Nair.

Hi Kenn,
You are probably better off posting this request in this forum User Interface Development in ABAP as you are more likely to get a response.

Make Select rows and columns as read only in Table Control

Hi All,
I would like to know how to make certain cells in a Table Control as display only.
Table control should look like-(Those in bold are read only or in display mode)
Name1 Idno1 Address1
Name2 Idno2 Address2
Name3 Idno3 Address3
Name4 Idno4 Address4
(Blank row to enter name idno and address)
(Blank row to enter name idno and address)
(Blank row to enter name idno and address)
My table control should display all the above fields the way it is above of which first two colums and 4 rows should be read only,and the rest of the empty rows in the TC should be in change mode.i.e it must have provision to add new rows but not change the first two columns of existing rows.
In short I am looking at solution to hide particular no of rows and columns and not the entire column.

In the PBO of the table control loop. just write these statements
NAME and IDNO considering the fields on the screen.
and WA_TAB is the table work area being passed to the table control to display the rows.
if not WA_TAB-NAME is initial and not WA_TAB-IDNO is initial.
loop at screen.
if screen-name = 'NAME' or
 screen-name = 'IDNO'.
screen-input = 0.
modify screen.
endif.
endloop.
endif.
which means that the fields are disabled only if NAME and IDNO are not initial.

Hi, how can i break the value for a row and column once i have converted the image to the array???????

Hi, I would like to know how can i break the value for a row and column once i have converted the image to the array. I wanted to make some modification on the element of the array at a certain position. how can i do that?
At the moment (as per attachhment), the value of the new row and column will be inserted by the user. But now, I want to do some coding that will automatically insert the new value of the row and the column ( I will use the formula node for the programming). But the question now, I don't know how to split the row and the column. Is it the value of i in the 'for loop'? I've tried to link the 'i' to the input of the 'replace subset array icon' , but i'm unable to do it as i got some error.
Please help me!
For your information, I'm using LABView 7.0.

Hi,
Thanks for your reply.Sorry for the confusion.
I manage to change the array element by changing the row and column value. But, what i want is to allow the program to change the array element at a specified row and column value, where the new value is generated automatically by the program.
Atatched is the diagram. I've detailed out the program . you may refer to the comments in the formula node. There are 2 arrays going into the loop. If a >3, then the program will switch to b, where if b =0, then the program will check on the value of the next element which is in the same row with b but in the next column. But if b =45, another set of checking will be done at a dufferent value of row and column.
I hope that I have made the problem clear. Sorry if it is still confusing.
Hope you can help me. Thank you!!!!

Getting Row and Column in ADF RC

Hi,
I have an ADF RC form with a table control on it. I need to find the row and column of the cell where the user has clicked. I am able to get the row using getSelectedRow() but am not able to get the column of the cell. Could anyone please help?
Thanks & Regards,

Hi Frank,
I need the coordinates. eg. My table is something like this
Country Region City Value1 Value2 Value3 Total
AAAAA BBBBB XXX 10 15 30 55
EEEEE YYY 5 2 15 22
TOTAL 15 17 45 77
etc.
If the user clicks on any cell in the country column he can add countries, if he clicks on any cell in the region column, he can add regions. The behavior changes for value1, value2, value3... if he clicks in any of these columns he can add value4, value5 columns. If he clicks on the actual data, he gets another screen.
Thanks & Regards,
Mike
