Chinese sort in JTable

Hello
I used the thread to sort a JTable in Chinese :
http://forum.java.sun.com/thread.jsp?forum=16&thread=369970
First, fsato4 (from the thread) says :
The array java.text.CollationKey[] generated from the method getCollatingKey of the class Collator with the locale java.util.Locale.TRADITIONAL_CHINESE is sorted according to radicals (first level) and strokes(second level) by default.
I did not find this information on any website (about the Radical sort first and strokes in second). Does anyone know where to get this information ?
Second :
I used the code of the thread to sort a JTable (one click on the header) but there is no difference between the "normal" sort (without using Collator) and the use of Collator. Is it normal ?
Finally is it possible to choose how to sort (strokes first and radicals in second) ?
Thanks in advance for your help

Actually this is a trivial thing except for a few cases of exceptions like GB2312 (i:pinyin -> ii:radicals) or JIS X 0208 (i:pronunciation -> ii:radicals).
I refer to 7.1.4 of the book, "Java Internationalization" by Andy Deitsch & David Czarnecki.

Turn off sort in JTable?

Hi
How can I turn off auto sort when I click on a column header in JTable obj in JClient/Swing and how to disable edeiting JTable contents.
Thanks

Could it be some sort of field issue with the encoding? When viewing on the Mac what screens are you viewing on? Won't they be non interlaced by their nature whilst a tv would be interlaced? Just thinking out loud here as to what might be the cause. We use pre-encoded assets all the time and (unless something has drastically changed in the latest SP- why?) it definitely doesn't re-encode pre-encoded assets.
I would have thought if it was re-encdoing you would be likely to see blocking than interlacing anyway...
Try re-encoding a small section - preferably one where you are seeing the interlacing issue worse - with some different settings in Cinemacraft and see if you can trac it down that way perhaps
Sorry I can't be more help

Sorting two Jtables at the same time

Hello
I have a problem and I don't know how to solve it.
I have two Jtables because I need to have some colums fixed and the others can be in a scrollpane. The problem is when I want to sort them. If I sort one the other is not sorted. I use TableSorter from Sun. Let's see a piece of my code:
            TableSorter sorterFixed = new TableSorter(modelFixed);
            fixedTable = new JTable(sorterFixed);
            sorterFixed.setTableHeader(fixedTable.getTableHeader());
            TableSorter sorter = new TableSorter(model);
            table = new JTable(sorter);
            sorter.setTableHeader(table.getTableHeader());
            jScrollPane = new JScrollPane(table);Anyone knows how can I do it?
Thanks !!!

I haven't tested this.. try and let us know
I guess, TableSorter will fire "fireTableDataChanged()". You can listen for this and update the next table.

Category (Group)wise sorting in JTable

Deadly need your help..I am using jdk1.4 as per the requirement,
I stuck up where in my JTable i have lot of records..but the first column is having some category..some thing like for category1 have some records and category2 i have some records..when i try to sort on other columns i would like to have them sorted in that first column category wise.Thanks in advance

Is there any column in subject area for catalog group? if you have you can use directly or else you need to define the group.
in this case pull category column twice and sales in Criteria
on 1st category column fx bin tab define the categories, once you done this select sum in results tab
Hope this helps

IP sorting in JTable

Hi
How to sort a IP Address column in JTable based on IPAddresses(not String sorting)?
Thanks

Are you working on String or InetAddress instances? If the latter, you could use the method "byte[] getAddress()" in a Comparator.

Sorting on JTable (JDK 1.6)

Hi,
I currently investigate the new sorting features of JTable in 1.6 (TableRowSorter, etc). By this I came across the following questions:
* Is there a way to access the sorting order of a column? [Background: my comparators are not symmetric: rows which do not contain any value in the given column need to be displayed always at the very end; at the 'beginning' all other rows are sorted accordingly]
* Is there a way to just use the new rendering of the table header, register for sorting events, and do the actual sorting 'manually'? [Background: I already have all the sorting and filtering capabilities in place (in a performance efficient way), but of course want to benefit from the new header rendering]
Any hints are welcome :-)
Thanks in advance,
Hans

Problem with the sorting of JTable column

Hi,
I want to store the positions of the tablecolumns when my program closes and restore them when the program starts again. I store their column-index with their view positions.
My problem comes when I want to restore them because I cant find a method to move the columns to their new position without compromising the ColumnModel() because then the you edit the model which with you are working with. See my example:
for (int i = 0;i < getColumnModel().getColumnCount();i++)
TableColumn tempColumn = getColumnModel().getColumn(i);
//get it's position
String position = (String) UserSettingsManager.getInstance().getItemFromMap(positionKey);
if (position != null)
getColumnModel().moveColumn(i, Integer.parseInt(position));
How can I get a list of all the column without using getColumnModel().getColumn() .... or how do I fix this.
Much thanks,
Hugo

See JTable's methods
public int convertColumnIndexToView(int modelColumnIndex)
public int convertColumnIndexToModel(int viewColumnIndex)
for (int i = 0;i < getColumnModel().getColumnCount();i++)
TableColumn tempColumn = getColumnModel().getColumn(i);
//get it's position
String position = (String) UserSettingsManager.getInstance().getItemFromMap(positionKey);
if (position != null)
int index=table.convertColumnIndexToView(i);
getColumnModel().moveColumn(index, Integer.parseInt(position));

Sorting the Model vs sorting the JTable

So,
now that I'm starting the rewrite of my program, I wanted to avoid as much dependencies as possible from the table component.
This, because my table (SwingX JXTable actually) gave me occasional problems and artefacts.
So, when I want to sort the data in the table, or filter it for example,
would it be faster to:
- sort the data model and reset the data in the table
or
- don't do anything with the model and let the table do the sorting and filtering?
Thanks in advance.

To OP:
Your question is contradictory.
First you want to avoid dependencies "from the table component" (I ssume you mean "on JXTable API"). Then you go on asking what would be "faster".
Other criteria that might be of interest (in addition to "dependencies maintenance" and "speed"), could be:
- memory usage: if you already know to filter, at the model level, your 1-M customer orders table, into a 10-lines summary for the current customer, then obviously you'll gain memory at the view level.
- ease of programming: if all order data are in-memory, and you can switch from one customer to the other, filtering at the view level spares one call into the model layer, and probably one DB call as well. A UI developper will be more confortable.
These are contrived examples, I just want to point out that "it depends" on what are your constraints (interactions, app-specific requirements, staff skill,...).
AFAIC, I don't remember having problems with sorting and filtering using Swing's native RowSorter API (I did shoot myself in the foot because I sometimes forgot to convert indices, view-to-model and model-to-view, in the event handlers, but once you remember that you're safe).
Maybe check on a SwingX forum for the (maybe SwingX-specific) artefacts.

Sort a JTable using TableRowSorter

Hello all,
I need to sort a table on a column, but the sorting trigger is coded in the program. Currently, I'm using the TableRowSorter.
All is good, except the sorting is not to be decided by the user, so I don't need the column header click trigger. More over, I also don't need to display on the header anything that might give the user the impression that he can trigger the sort, that is i don't need any sorting arrows.
Does anyone have an idea how to do this clean? Until now, the only solution I have is to do the sorting myself, but it's somewhat messy.
Thanks and best regards,
Domi

the arrows won't disappear even if there's no comparator / no column is sortableI see, setting a column as non sortable prevents further sorting, but the arrows remain. I don't really think thats a bad thing as it does give the user a visual cue that the table is sorted in that order.
I agree that it might be a bit confusing in that the user might think they can then resort the table. So maybe the solution is to use a custom renderer. The arrow could be renderer in a "disabled" state to remove the confustion. Or, you could remove the arrow altogether.
You might be able to start with Darryl's [Default Table Header Cell Renderer|http://www.camick.com/java/blog.html?name=default-table-header-cell-renderer]. I believe the default implementation does paint the arrows, but you should be able to easily customize that behaviour.

Multiple column sorting on JTable data

if any body can please send an example code how multiple column sorting can be done on table data.
condition:- one column should sort in ascending order another column in descending order.
am completly out of ideas it's urgent any help is greatly appritiated
Thank's in advance
sri

I think the crosspost is because the OP was advised to post it in the Swing forum instead (it would've been nice to see the original post closed as well, though). Anyway...
Have you got your table sorting using one column? If so, how have you achieved that (eg, are you using Java 6)?
All you're after is a stable sorting algorithm so that any elements that are the same in the new sorting scheme stay in the same position relative to each other. Then you can just sort by "Column B" then "Column A" to achieve multiple column sorting. I believe that Collections.sort is stable and therefore any sorting approach based on that should be easily modifiable to do what you want.
Hope this helps.

The result of sorting Chinese is weird

I am evaluating Oracle 9i's Chinese sorting feature.
I insert several Chinese records into a UTF-8 database, set my client session's NLS_SORT parameter to one of the Chinese sorts Oracle 9i supplied, then retrieve the ordered result.
From the view of a native Chinese user, I find the result is weird. It is sorted based not on Pinyin nor on Stroke count. So what's the matter?
My database's parameters are:
NLS_LANGUAGE AMERICAN
NLS_TERRITORY AMERICA
NLS_CHARACTERSET UTF8
NLS_SORT BINARY
NLS_NCHAR_CHARACTERSET AL16UTF16
I've tried:
Alter session set NLS_SORT=SChinese_Stroke_M;
Select * from SChinese order by Chinese;
And
Select * from SChinese order by NLSSORT(Chinese, 'NLS_SORT=SCHINESE_PINYIN_M');
Thanks in advance.
Doug Wang.

Hi Barry,
Thanks for your prompt reply.
At first I created a table with a Nvarchar column in it. Then I populated the data from the above table to another table with a varchar column. The ordering results are the same.
I dump the NLS parameters as follows: (The character set of my db is UTF-8)
PARAMETER VALUE
NLS_LANGUAGE AMERICAN
NLS_TERRITORY AMERICA
NLS_CURRENCY $
NLS_ISO_CURRENCY AMERICA
NLS_NUMERIC_CHARACTERS .,
NLS_CALENDAR GREGORIAN
NLS_DATE_FORMAT DD-MON-RR

NLS_DUAL_CURRENCY $
PARAMETER VALUE
NLS_COMP ANSI
NLS_LENGTH_SEMANTICS BYTE
NLS_NCHAR_CONV_EXCP FALSE
