JTable multi column sorting (jdk 1.5)

Hi,
Can you please send a short example (and/or a link) to multi column sorting using sun TableSorter class ?
Thanks a lot,
Ido

Read the Documentation that comes with the TableSorter class. I believe you use Shift+Click or Control+Click to sort multiple columns.

SWT table widget and multi column sorting

Hello,
I want to make the standard SWT table widget support multi column sorting.
Searching on the web didn't lead to useful results. The Nebula project should be the last option.
I guess I need a comparator chain, but how do I realize aspects like let columns appear blue when marked or mark multiple columns by pressing shift key and left mouse button?
Any examples are much appreciated.
Thank you very much!
Regards,
Mick

Multi column sorting

I am wondering if it is possbile to sort data grids in multi
columns?? For example lets say the data grid simply looks like
this:
Name
Date
Art 10/29/06
Chris 12/02/04
Bob 02/21/07
Bo 08/08/05
And i want to sort it in abc order first then within that
sort(abc order) have does be sorted again by date so that A's will
stay together, B's and so on...Is this possible and if so how?
Thanks for all the help

here is what i have...it crashes after the first click....
rivate function ctrlCheck(ke:KeyboardEvent):void // checks to
see if the ctrl key is pressed to do a multicolumn sort.
if( ke.keyCode == 17) ctrlChecker =true;
else ctrlChecker = false;
private function resortColumns(le:ListEvent):void //if there
is more than one page of results resort the columns and requery,
else just resort
colSortedOn = new String("");
var sortDirection:String = new String("");
var s:Sort=new Sort();
var count:int=0;
var arr:Array=new Array();
if(le.rowIndex == 0)//get the column sorted on and attach
that to the query and requery
if(ctrlChecker==true)
while(ctrlChecker==true)//while the user is still holding
the ctrl key
colSortedOn =
DataGridColumn(datagrid1.columns[le.columnIndex]).dataField.toString();
if(DataGridColumn(datagrid1.columns[le.columnIndex]).sortDescending)
sortLoadDirection = true;
else
sortLoadDirection = false;
arr[count]=new SortField(colSortedOn, true,
sortLoadDirection)
count ++;
for(var i:int =0; i<arr.length; i++)
s.fields
=arr
datagrid1.dataProvider.sort= s;
datagrid1.dataProvider.refresh();
else //there is no sort order taking place, the item click
was something else entirely
parentDocument.sortCheck = 1;
}

Multiple column sorting in JTable

There is way to release multiple column sorting in JTable.

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.

Interactive Report wide Column Sorting hangs in Internet Explorer

I have an application that contains an interactive report. The Column Sorting and Filtering functions work fine in Firefox. However, if I try to sort a wide (110 byte - it contains a hyperlink) column in Internet Explorer, APEX produces the 'loading data' image and then hangs. Even a sort of a narrow (3 byte) column is noticeably slower in Internet Explorer than in Firefox.
We are running APEX 3.1.1 on Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production with the Partitioning, OLAP, Data Mining and Real Application Testing options

Hello,
I answer you over your post.

Hi,
That's an interesting issue. What kind of images are these? Are they the default images installed or are they your custom set of images?The images are png files included as they were icons into the table.

You say the images disappear when you sort the report. Does it happen when you sort on demand in the dashboard or when you sort it in the report itself? Or both?Only when sort from the dashboard. From the report itself, the answers works fine.

Customizing column sorting in new jsf table

The new JSF table in the creator 2 is great. I like it. It includes so many out of the box features. It is the reason we use the creator for our current project.
But I cannot figure out how to customize the column sorting.
Why do I need column sorting?
I need to sort a column that can include ad IP address or a host name. Our customer can either use a host name or an IP address to address a device in the network, both in the same column.
Now sorting an IP address is already difficult. It is actually a sort over a 4 byte number. Sorting over host names is normal alphabetic string sorting.
How to sort over both in the same column?
This cannot be done using standard sorting. I need to use a validator or something similar to customize the sorting of this column.
Can anybody help me with a hint if:
1- Customizing sorting over a column is possible. (I really would like to keep all other sorting features (icons, multi column support...)).
2- A hint or code sample, how to do this.
If this is not possible, I urge the creator team to think of implementing this soon. Otherwise one killer feature of the creator 2 will lose a lot of its teeth.

Thx mayagiri for your reply!
But including the src-code for the dataprovider package into a test project, and debugging in the creator-ide has done the thing!
Here our solution:
Class ToCompare is the object type which address field displayed in a page, simply containing a table with 2 adress colums, that can be sorted either according to our ip/hostname-comparison or according to String.compare().
* ToCompare.java
* Created on 10. Februar 2006, 10:41
* This class is a basic model object,
* with a field - String address - according
* to which it shall be sortable.
package comparator;
* @author mock
public class ToCompare {
     * holds the IP or Host address
    private String address=null;
     * Instance of a Comparator class that
     * provides our sorting algorithm
    private RcHostComparator hostComparator=null;
    /** Creates a new instance of ToCompare */
    public ToCompare() {
        this("defaultHost");
     * when creating a new ToCompare instance,
     * the hostComparator is created for it
     * @ param aAddress - IP or Hostname
    public ToCompare(String aAddress) {
        address=aAddress;
        hostComparator=new RcHostComparator(address);
    public String getAddress() {
        return address;
    public RcHostComparator getHostComparator() {
        return hostComparator;
}Here the code of the Class RcHostComparator, it is created with the address field of the ToCompare object that it holds. It first checks if the address field is an IP or not, and then chooses the comparison algorithm according to its own field state and the field state of the object to compare to:
* RcHostComparator.java
* Created on 10. Februar 2006, 10:43

JTable - make column headers clickable

Hi all
I have a JTable, and now I want to sort by column. I've actually got the column sorting working using menu items, but how can I make my column header clickable, and where do I add an actionListener to?

    public void addMouseListenerToHeaderInTable(JTable table) {
        final JTable tableView = table;
        tableView.setColumnSelectionAllowed(false);
        MouseAdapter listMouseListener = new MouseAdapter() {
                    public void mouseClicked(MouseEvent e) {
                        TableColumnModel columnModel = tableView.getColumnModel();
                        int viewColumn = columnModel.getColumnIndexAtX(e.getX());
                        int column = tableView.convertColumnIndexToModel(viewColumn);
                        if (e.getClickCount() == 1 && column != -1) {
                            int shiftPressed = e.getModifiers() & InputEvent.SHIFT_MASK;
                            boolean ascending = (shiftPressed == 0);
                            // sort
        JTableHeader th = tableView.getTableHeader();
        th.addMouseListener(listMouseListener);
    }

Text query using a Multi Column datastore index slow

I have created a text index using multi column datastore preference. I have specified two clob columns in my preference. Searching on this new index works, but it is slower than I expected.
I have done the following comparison:
My original two clob columns are: DocumentBody and DocumentFields. I have built an individual text index on each column. My new column with Multi Column index is DocumentBodyAndFields;
I did two queries:
1. search 'dog' on DocumentBody UNION search 'dog' on DocumentFields;
2. search 'dog' on DocumentBodyAndFields;
I would think the second search should be faster than the first one because it is a single query. But this is not the case. The second query is consistently slower than the first query by about 10-20%.
Things are getting much worse when I search on preceding wildcards. If I search '%job', the multi column index is twice as slow as the first query! I am very confused by this result. Is this a bug?

I am unable to reproduce the performance problem. In my tests, the search that uses the multicolumn_datastore performs better, as demonstrated below. Can you provide a similar test case that shows the table structure, datastore, index creations, and explain plan?

Multi-Column Report Issue

I am using the Crystal Reports edition bundled with Visual Studio 2005. I have a problem with a multi-column report. It is a two column member directory with family members. It lists the member name, contact info, spouse, and children. I want each family group to stay together, and not break cross a column or a page. Each group may have from 3 to a dozen or so lines.
The family groups will not break across a page (which is good), but they will break across a column (bad). I have tried many combinations of settings to make this work without success.
So I wonder if anyone has seen and resolved this problem, or if perhaps it works better in the full version of Crystal.

In some sub-sections, I have checked 'Suppress Blank Section' checked. In others, I have a suppression formula.
Each section has only a single field.
The record set that the report uses has a single row for each person. The sorting and grouping is arranged so that the first record in each family group is the 'main' member. The report displays this person's name, and also shows the sections which include address and phone number info. Subsequent records are for family members (spouse and/or children). For these records, I display the name, but suppress the address and phone sections.
There is also a detail sub-section used as a group header. This group breaks when the first letter of the last name changes, so it an display a single letter heading ("A"). I had tried this as a regular group header too, but it didn't help.
I have tried combining all the sections into a single one with each field on a separate line (which means the section can have some blank space), and also combined into a text box. No luck.
I also have the group itself set to "Keep Together' in the group expert. Doesn't help/

JTable Multi-Span Cell Example

Searched the Forum und Google for the "JTable Multi-Span Cell Example" and always found this Link :
http://www2.gol.com/users/tame/swing/examples/SwingExamples.html
But the Examples are only working with JDK 1.3.1, JDK 1.4.1 and JDK 1.4.2 aren`t working anymore.
What do i have to change, or are there any new examples for Multi-Span Cells in the JTable provided by SUN ?

In AttributiveTableCellModel.java, rewrite the following function:
public void setDataVector(Vector newData, Vector columnNames) {
if (newData == null)
throw new IllegalArgumentException("setDataVector() - Null parameter");
dataVector = new Vector(0);
setColumnIdentifiers(columnNames);
dataVector = newData;
super.setDataVector(newData, columnNames);
cellAtt = new DefaultCellAttribute(newData.size(),
columnIdentifiers.size());
newRowsAdded(new TableModelEvent(this, 0, getRowCount()-1,
TableModelEvent.ALL_COLUMNS, TableModelEvent.INSERT));
}

How do i create a Multi column Dynamic list using Swing?

Hi,
I need to be able to do a file search (in a separate thread) on the hard drive and display the results in a multi column List control .
Jtable seems to be rather 'static'y. i.e load data in once. and maybe reload it again later. But i need to load one row in at a time as the search progresses.
Also any row can be deleted or moved to another position.
CListCtrl in MFC allows me to do this handily.
But Is there a way to do this using Swing?
havent seen anything that says JList can do this.
TIA

Hi Jacob.
I would use JTable for that. I did not exactly understand what you meant by JTable being "static"y.
Anyway, I would have the thread update the data in the tablemodel behind the table and invoke "fireTableRowsInserted" (may be after every insert or after inserting a chunk of rows). I had a sample something similar to what you are working on. Let me know if you need the sample.
HTH.

Vijay

Unable to capture the adf table column sort icons using open script tool

Hi All,
I am new to OATS and I am trying to create script for testing ADF application using open script tool. I face issues in recording two events.
1. I am unable to record the event of clicking adf table column sort icons that exist on the column header. I tried to use the capture tool, but that couldn't help me.
2. The second issue is I am unable to capture the panel header text. The component can be identified but I was not able to identify the supporting attribute for the header text.

Hi keerthi,
1. I have pasted the code for the first issue
web
                         .button(
                                   122,
                                   "/web:window[@index='0' or @title='Manage Network Targets - Oracle Communications Order and Service Management - Order and Service Management']/web:document[@index='0' or @name='1824fhkchs_6']/web:form[@id='pt1:_UISform1' or @name='pt1:_UISform1' or @index='0']/web:button[@id='pt1:MA:0:n1:1:pt1:qryId1::search' or @value='Search' or @index='3']")
                         .click();
                    adf
                    .table(
                              "/web:window[@index='0' or @title='Manage Network Targets - Oracle Communications Order and Service Management - Order and Service Management']/web:document[@index='0' or @name='1c9nk1ryzv_6']/web:ADFTable[@absoluteLocator='pt1:MA:n1:pt1:pnlcltn:resId1']")

Multi-column BITMAP index vs. multiple BITMAP indices?

Given the table (simple, made-up example):
CREATE TABLE applicant_diversity_info (
applicant_diversity_id NUMBER(12), PRIMARY KEY(applicant_diversity_id),
apply_date DATE,
ssn_salted_md5 RAW(16),
gender CHAR(1), CHECK ( (gender IS NULL OR gender IN ('M','F')) ),
racial_continent VARCHAR2(30), CHECK ( (racial_continent IS NULL
OR racial_continent IN ('Europe','Africa','America','Asia_Pacific')) ),
ethnic_supergroup VARCHAR2(30), CHECK ( (ethnic_supergroup IS NULL OR ethnic_supergroup IN ('Latin American','Other')) ),
hire_salary NUMBER(11,2),
hire_month DATE,
termination_salary NUMBER(11,2),
termination_month DATE,
termination_cause VARCHAR2(30), CHECK ( (termination_cause IS NULL
OR termination_cause IN ('Resigned','Leave of Absence','Laid Off','Performance','Cause')) )
Oracle (syntactically) allows me to create either one BITMAP index over all four small-cardinality columns
CREATE BITMAP INDEX applicant_diversity_diversity_idx ON applicant_diversity_info (
gender, racial_continent, ethnic_supergroup, termination_reason );
or four independent indexes
CREATE BITMAP INDEX applicant_diversity_gender_idx ON applicant_diversity_info ( gender );
CREATE BITMAP INDEX applicant_diversity_race_idx ON applicant_diversity_info ( raceial_continent );
etc.
What is the difference between the two approaches; is there any meaningful difference in disk-space between the one multi-colum index and the four single-column indexes? Does it make a difference in what the query-planner will consider?
And, if I define one multi-column BITMAP index, does the order of columns matter?

You may want to read this two-part blog, that answers that exact question, by recognized expert Richard Foote

As with many things Oracle the answer is 'it depends'.
In short the same considerations apply for a concatenated index whether it is bitmap or b-tree: 1) will the leading column usually be in the predicate and 2) will most or all of the index columns be specified in the queries.
Here are some quotes from part 1
>
Many of the same issues and factors in deciding to create a single, multi-column index vs. several, single column indexes apply to Bitmap indexes as they do with B-Tree indexes, although there are a number of key differences to consider as well.
Another thing to note regarding a concatenated Bitmap index is that the potential number of index entries is a product of distinct combinations of data of the indexed columns.
A concatenated Bitmap index can potentially use less or more space than corresponding single column indexes, it depends on the number of index entries that are derived and the distribution of the data with the table.

Here is the lead quote from part 2
>
The issues regarding whether to go for single column indexes vs. concatenated indexes are similar for Bitmap indexes as they are for B-Tree indexes.
It’s generally more efficient to access a concatenated index as it’s only the one index with less processing and less throwaway rowids/rows to contend with. However it’s more flexible to have single column indexes, especially for Bitmap indexes that are kinda designed to be used concurrently, as concatenated indexes are heavily dependant on the leading column being known in queries.

How Can I get multi column values from dynamic search help?

Hi Gurus;
I'm using dynamic search help in my program.
I want to get multi column values from search help. But I dont know solution for this issue.
I'm using F4IF_INT_TABLE_VALUE_REQUEST FM.
How Can I get multi column values from dynamic search help?
Thanks.

Believe it or not, the same FM worked for me in a dynpro. I will try to explain here how it works in custom screen and then you can do your work for other screens or program types. I am not going to write my actual work but will explain in general.
I have 4 fields (FLD1, FLD2, FLD3, FLD4) and i made the search based on FLD2 and when user click on a line (could be any field), then this would bring the line on to the screens.
There are like 3 steps.
You have your value_tab for my fields FLD1, FLD2, FLD3 and FLD4. This is just the data that we pass into the FM. (data: IT_VALTAB type table of ZVAL_TABLE)
Next map the screen fields into an internal table (data: It_dynpfld type table of dselc ). I also have other internal tables defined (just to keep it straight, i will be putting here) data: It_return type standard table of ddshretval.
Next step is to call the function module. Make sure you have values in IT_VALTAB.
call function 'F4IF_INT_TABLE_VALUE_REQUEST'
exporting
        retfield        = 'FLD2'
        value_org       = 'S'
      tables
        value_tab       = It_VALTAB
        return_tab      = It_return
        dynpfld_mapping = It_dynpfld
      exceptions
        parameter_error = 1
        no_values_found = 2
        others          = 3.
    if sy-subrc <> 0.
      message id sy-msgid type sy-msgty number sy-msgno
      with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    else.
      perform get_selected_fields tables It_return.
    endif.
The code within the perform GET_SELECTED_FIELDS - We need to map the result fields after user selects it. The code goes like this. This is step is to update the dynpro fields.
I need a internal table as well as a work area here. like,
data: lt_fields type table of dynpread,
        la_fields type dynpread.
field-symbols: <fs_return> type ddshretval.
so fill out LT_FIELDS from the IT_RETURN table
loop at lt_return assigning <fs_return>.
    la_fields-fieldname = <fs_return>-retfield.
    la_fields-fieldvalue = <fs_return>-fieldval.
    append la_fields to lt_fields.
    clear: la_fields.
endloop.
Call the FM to update the dynpro
call function 'DYNP_VALUES_UPDATE'
    exporting
      dyname               = sy-repid
      dynumb               = '1002' "This is my screen number. You could use 1000 for selection screen (hope so)
    tables
      dynpfields           = lt_fields
    exceptions
      invalid_abapworkarea = 1
      invalid_dynprofield = 2
      invalid_dynproname   = 3
      invalid_dynpronummer = 4
      invalid_request      = 5
      no_fielddescription = 6
      undefind_error       = 7
      others               = 8.
if sy-subrc <> 0.
    message id sy-msgid type sy-msgty number sy-msgno
            with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
endif.
good luck
