Jtable row-based renderer
Hi,
I have a JTable with 6 columns and several rows, and I want to paint the rows depending on the value of a cell in that row.
I looked at the tutorials, and it seems to me that it's easy to paint a whole column, but not a whole row.
How can I do this ?
Thanks
This was from a project I did. It is a renderer for a sortable/Drag and dropable JTable. Rather specialized but it works for me. You should be able to pull out what you need. It actually will color rows based on two different column values.

JTable filtering based on comparison of values in a row
I need to implement a RowFilter that will make its 'include' decision by comparing values in two columns of a JTable row. All the RowFilter.getxxxFilter() methods I see require external input, for example:
RowFilter.numberFilter(ComparisonType.EQUAL, 10, 1, 2);as I understand it, this filter will filter out all rows that do not contain the value 10 in column index 1 or 2. What I need is something like:
RowFilter.numberFilter(ComparisonType.BEFORE, 1, 2);Where it will only include rows where the value in column 1 is less than the value in column 2.
Does RowFilter support this without having to write my own RowFilter subclass? It looks easy enough to write, but I wanted to make sure I understood the API correctly before I go reinventing the wheel.nice day,
I pretty not sure what is comparing values in two columns of a JTable row but maybe this one can hepl you import java.util.*;

Changing JTable Row Color OnMouseOver
Hello everybody,
is it possible to change JTable Row Color when Mouse passes over it ??
THanks!Yes...
You have to override the table cell renderer and set the color of the rows based on flag.
The flag can be turned on/off in a mouse motion listener of the table. -
Why is my JTable row sort is not working?
Hey all,
I wrote the following code for a JTable and I'm trying to use a table sorter to sort the first column content alphabetically, for now. Later, I'd like to use the third column and sort the table's rows based on ascending dates.
For some reason, my comparator is not being called at all and I'm not sure what I'm doing wrong. I'm using JDK 6, which allows me to use a TableRowSorter. It is the first time I'm using this, so I may not know how to use it correctly. Does anybody have any idea what I'm doing wrong?
Please advice.

The table provides a default Comparator to sort dates. You just need to tell the table what type of data is stored in each column. This is done by overriding the getColumnClass() method of JTable or TableModel.
Camickr, you once said that the table provides a default Comparator to sort dates. and I just need to tell the table what type of data is stored in each column. This is done by overriding the getColumnClass() method of JTable or TableModel.

}hi again camickr
i changed the stopCellEditing as you mentioned
changed the getCellEditorValue to return an integer
and give exception and error message if the value can't be converted into integer(non numeric)
but the problem is when i run the program and change the value in any cell with numeric values
or with non numeric or not changing the value and press enter
it give the error message meaning it cannot convert the value to integer
even if enter an int or don't change the value ????????

Table Control - Input Enabling/Diabling of Rows based on Condition.
Hi,
In the TC, I want to Input Enable/Disable the rows based on Conditions. The First row is input enabled always. But the other rows, (2nd onwards) need to be Input Enabled/Disabled based on some conditions. It is possible to make this working. Can you please provide me a suitable solution for this?
Appreciate Your Help.
Thanks,
KannanHi Kannan...
If we are talking about "Rows"...
then identify based on some conditions the row numbers and in PBO...loop at screen with screen name..set thier input properties and modify screen (make them input only)
If we are taking into consideration "columns"
There is an internal structure COLS where we can identify column number of screen name ...or we can take except for one particular column..
if some condition satisfied....
loop at screen where screen-name <> "Column which is input'.
Loop at screen...and make other columns display only.
modify screen
endif.

Count the number of rows based on the values!!!
Hi all,
What I am using:
I am working with a multidimensional database in Visual Studio 2010 using its Data source view and calculation member and dimension usage.
What I want to do:
I have a fact table that has five columns(leg(s),hand(s), Head and body,overall) that shows the category of how severe the injury is. Let say for the records all columns never have an empty value(no injury is stated with 'No injury' ) . These five columns
are connected with a dimension that has all the available values (Category A-E of injury).The overall has the most severe from the other four columns. I want to create a bar chart with five different measure
values, one for each column, and count the values in those columns.
For example : I have a slicer in the excel and a bar chart and the slicer has all the values of the Category of the injury ( Cat a,Cat B, Cat C, ... Cat E, No injury ) and when i select one of them, lets say
Cat C, the bar chart should update and show how many Cat C each measurement column has.
Example FACT table:
ID LEG HAND HEAD BODY OVERALL
1 No A No No A
2 No D C C C
3 E C D A A
4 E E B C B
So if i selected C the bar chart will count (Leg = 0, Hand = 1, Head = 1, body = 2 and Overall = 1).
Any ideas ?
Thanks for the help and the time :)Hi DBtheoN,
According to your description, you want to create a chart on excel worksheet to count the rows based on the value, right? If in this case, I am afraid this issue is related to Office forum, I am not the expert of Office, you can post the issue on the corresponding
forum.
However, this requirement can be done easily on SQL Server Reporting Services. You can using the expression below to count the rows.
=COUNT(IIF(Fields!LEG.Value=Parameters!TYPE.Value,1,NOTHING))

How can I select and delete rows based on the value in one column?
I searched through the discussion board, and found a thread on deleting blank rows, but not sure how to modify it to work with my issue.
I have put together a rather complicated spreadsheet for designing control systems, it calculates parts needed based on check boxes selected in a second spreadsheet.
Since not all systems require all parts there are many rows that have a 0 quantity value, I would like to select these rows and delete them once I have gone through the design phase (checking off required features on a separate sheet).
I like the way the other thread I found will gather all the blank rows at the bottom without changing the order of the rows with data in them.
I don't understand exactly how the formula in the other thread works well enough to modify it to look for a certain column.
I hope I made myself clear enough here, to recap, I would like to sort the rows based on a zero value in one (quantity) column, move them (the zero quantity rows) to the bottom of the sheet, and then delete the rows with a zero quantity (I can delete them manually, but would like to automate the sorting part).
Thanks for any help anyone can provide here.
DannyI apologize but, as far as I know, Numbers wasn't designed by Ian Flemming.
There is no "this column will be auto-destructing after two minutes"
You will have to use your fingers to delete it.
I wish to add a last comment :
if your boss has the bad habit to look over your shoulder, it's time to find an other one.
As I am really pig headed, it's what I did. I became my own boss so nobody looked over my shoulder.

Deleting duplicate rows based on three columns in Oracle 8i
Hi all,
The database we use is Oracle 8i.
The query below raises the too_many_rows exception when I launch an application. So I want to delete the duplicated rows :
select polarisation_1, polarisation_2
into v_pol1_tech, v_pol2_tech
from v_cfh_lien_element
where nom_lien = p_nom_lien
AND num_canal_1 = p_num_canal_1
AND freq_emise_1 = p_freq_emise_1;
Notice that with many possible values of the parameters p_nom_lien, p_num_canal_1 and p_freq_emise_1 then the exception is raised.
So how to delete generally the duplicated rows based on the three columns "nom_lien" , "num_canal_1" and "freq_emise_1" ?
Thank you very much indeed.Check the other thread with same question deleting duplicate rows based on three columns in Oracle 8i

ORA-20101: Row based mode not supported
Hi,
I'm having this situation:
Process flow with 4 mappings ends with 2 mappings successfully and 2 mappings with error:
ORA-20101: Row based mode not supported
But when I started those mappings separatly (one by one) they've all completed successfully.
Is it possible that default operating mode and generation mode can cause this error? On those 2 mapping that failed the default operating mode and generation mode was SET_BASED. But it was the same when I ran them again and they did complete with success..
Has anyone came accross with this or similar situation?
Any help would be much appreciated.
Regards
VedranVedran,
What's the version of owb you are using?
can you post header of the package assiociated to process flow?
I had a problem running my "Set Based" mapping. It fails with the same error message "Row based mode not supported".
I noticed that the sequence of "Generation Mode" in my OWB 11.2 (on windows) was:
row_based = 1
row_baesd_target =2
set_based=3
set_based_failover=4
set_based_failover_target=5
but that of related package header was:
MODE_SET CONSTANT BINARY_INTEGER := 0;
MODE_ROW CONSTANT BINARY_INTEGER := 1;
MODE_ROW_TARGET CONSTANT BINARY_INTEGER := 2;
MODE_SET_FAILOVER_ROW CONSTANT BINARY_INTEGER := 3;
MODE_SET_FAILOVER_ROW_TARGET CONSTANT BINARY_INTEGER := 4;
I think it is a bug because changing this part of package as following and recompiling the package, my problem has been solved:
MODE_SET CONSTANT BINARY_INTEGER := 3;
MODE_ROW CONSTANT BINARY_INTEGER := 1;
MODE_ROW_TARGET CONSTANT BINARY_INTEGER := 2;
MODE_SET_FAILOVER_ROW CONSTANT BINARY_INTEGER := 4;
MODE_SET_FAILOVER_ROW_TARGET CONSTANT BINARY_INTEGER := 5;

Row based Target only mode not supported
when i try to execute a mapping i am getting the following error
Row based Target only mode not supported
what can be the reasons for thisHello Michael
Check if you have a procedure (other than pre or post mapping) in your mapping. Every part of a mapping after a procedure can only be generated in row-based mode.
Hope this helps

Insert new rows based on user selection on a table display on the screen
Hi..
In my requirement i need to display the line items of a PO# to the user on the screen for specific fields. Each row should also include an additonal checkbox when displayed for the user. When the user checks this check box or clicks on it a new row should be inserted below to that row with the existing data of that row being copied to newly inserted row and allowing the user to make any changes.
The newly inserted row should also include a check box , so that when the user checks it again a new row should get inserted. Finally what ever data user enters on the screen, i should be able to update my internal table with those new values and records.
Appreciate if anyone can guide me on how to proceed on this or any alternative approaches.
Will reward helpful answers.
Thanks.Hi ..
Can you please be more detailed. First I need to know how to create the initial table display for the existing line items and then the techniques for inserting the new rows based on the check marks and finally add those news rows to my existing internal table..
Appreciate ur help.
Thanks.
