Still, I do not research how to unregister yet,

Good luck.

Tricky Query regarding JTables.

This is a bit tricky regarding JTables
I have run the flwg query
select id_status 'STATUS',id_entity 'ENTITY'
from TableA
group by id_status,id_entity
Output
STATUS ENTITY
100      AGL
123      BSS
234      RDB
245      GERI have now both the rows and cols in 2 vectors.
The Output I want is this:
Depending on the No.of entities displayed above,these then
become the column headings and the 4 rows will be shown as one row:
OUTPUT REQUIRED:
Type   AGL   BSS   RDB   GER
Files 100   123   234   245I am able to display the 4 entity names as columns names by :
for ( int i = 0; i < rowCount; i++ ) {
m_colName.add(stm.getValueAt(i,2) ); // Where m_colName is a vector.
JTable table = new Table(m_rowName,m_colName);Now how do I read the data from the row Vector which now contains 4 rows
as one row and display them
This is my current row display (which is my current row display)
for ( int i = 0; i < rowCount; i++ ) {
     m_rows    = new Vector();
     for ( int z = 0; z < colCount; z++ ) {
          m_rows.add(stm.getValueAt(i,z) );
     // Vector of vectors.
     m_rowValues.addElement(m_rows);
}I may have to modify the above code so that the 4 rows are displayed as one row
and displayed as discussed above.
My present output is
AGL   BSS RDB GER

123
234
245Please help me now to read the 4 rows as one row and display them.

Wrong use of rows/columns. Try like below:
for ( int i = 0; i < colCount; i++ ) {
     m_rows    = new Vector();
     for ( int z = 0; z < rowCount; z++ ) {
          m_rows.add(stm.getValueAt(i,z) );
     // Vector of vectors.
     m_rowValues.addElement(m_rows);
}You weren't so far from it ;-)

Help regarding JTable in Java Swing

hi,
i m confused regarding JTable in Swing. i hav added a JTextField in a cell of a JTable. i hav attached a kay listener with that textfield . But when i m selecting that cell ,where i hav added that textfield with a single click and typeing any key i m not getting that keyevent. But when i m selecting the same with a doulbe click and typing any thing i m getting that event .
can any one tell me why the discrepency taking place. that textfield is
there in that cell .then how it does make any difference with a single and double click.
regards

i hav added a JTextField in a cell of a JTableYou don't add a text field to a cell in a table. You add a text String to the TableModel. When the user double clicks on the cell an 'editor' is invoked and the text is copied to the editor (which by default is a JTextField). So the KeyStrokes go to the editor text field.
When you just single click on a cell the table still has focus, not the editor, to the KeyStroke character is passed directly to the text field without the text field actually getting focus.

Urgent Regarding Jtable TAB and Arrow keys

Hi guys and gals,
In my project i need urgnet help regarding Jtable.I want to use DOWN ARROW key same as TAB function.When i reach the first row last editing coulmn by using arrow key,then i habe to creating a new row with default values.And if press UP key if that row contains no values i have to delete.Plz help me in this regard.
sreeni

I meant that the laptop freezes in gdm and in console (tty1). In gdm i can't even type any character. And in console i can login but when i press the tab key (autocompletation) it stops. The only thing i can do is press the power button.
Actually my keymap is es_ES. And i think that it's working fine because the n tilde and pipes work fine.

Cross-JTable selection

In a scenario where there are two JTable's in order to implement "locked (frozen) columns", one has to address the cross-JTable selection issue that occurs when both tables' "columnSelection" and "rowSelection" properties are enabled, and the user clicks & drags the mouse to select a range of cells across the two JTables.
Has anyone ever done this?
Mert

Interesting question - I would try to register one mouseListener to both tables that makes sure the events are redispatched if the mouse exits the one and enters the other during a addSelection.Or you can try to patch the BasicTableUI.MouseHandler to go on with addSelection even after a mouseExited during a mouseDragged. Never tried it, though. (Always assuming that one there is one selectionListener that extends a selection in one table to the other)

Regarding at selection screen event

hi experts,
i m working on hr abap report with the help of pnp ldb i made my selection screen using report category 'PY_DEF' now what i want that i m not using the first selction screen which contains current period details etc but when i click on the payroll period button the second selection screen is coming no doubt... containing payroll area current period ,other periods etc here i m entering payroll area eq 'ka' and other periods from '012006' to '122006' ,,here i want to validate the user input that it sud be of one year that is from 1 to 12.....for this i know i will use at selection event but how can i use it for the second selection screen not for first screen......... plz help me....

Do u realy need the first selection screen having the current period? If u don't need then u can hide the field in the report category, by passing only the payroll area with other period, in this case we can validate through selection screen..

JTable selection problem with jdk1.5.0_05

Today I tried the new jdk1.5.0_05 release and noticed with a JTable I can only select a single column and row with the mouse. With jdk1.5.0_05 I could select multiple cols and rows with the mouse. I looking at the listselectionmodel for the jtable i see it is set to mulitple. Is this a bug in the new java 1.5 release?

Yeah, the .jar files are definitely there and the
small class I just wrote is in the Classes directory.Yes, but you're calling javac.exe, not some jars. Did you check that javac.exe is there? Stupid question, yes, but I've seen it all...
I changed the path in Control Panel -> System ->
Advanced -> Environment Variables. I've also beendoing this is the command prompt:
set
CLASSPATH=%CLASSPATH%;C:\Java\jdk1.5.0\bin;C:\Java\Cla
ssesNo need to add the /bin directory to the classpath, there are no classes in it...

Intermittent JTable Selection Problem

Hi,
Everyone once in a while, under NT with 1.4.x, I have problems selecting and highlighting row under JTable. It happens a good bit, but this does not happen all the time. When the table is buggy, it does not keep the row selected nor does it highlight the row. You may have the row selected on a mousedown, but once you release the mouse it's done.
Since this is happening for a variety of JTable's I didn't bother to send Java code. Has anyone else encountered this sort of thing? Or does anyone know what I should be looking at?
The intermittent part is what's killing me. It makes it hard to track down with any high degreee of confidence in the answers.
thanks for any input or suggestions,
Geoff

Regarding the select query

Hi Experts,
I have a select query as follows:
select field1 field2 from db1 into table it1.
Now suppose the it1-field1 contains values a,b and c.
Now I want to select fields a,b and c from another db table db2.
Instead of hard coding like this:
select a b c from db2 into table it2.....
How can I do this?
Points will be awarded.
Regards,
Soumya.

Hi Soumya ,
Pleas use FOR ALL ENTRIES syntax , in this way you can select the records from db2 which are available or selected in db1.
Like Header And Item table.
You select records frm header table . then for corres ponding header records you select from detail table db2 .....
Condition is the field containg a,b,c is key field in both tables ...
Reward points if it helps you .

and 4 input fields.
SELECT-OPTIONS : S_MATNR FOR MARA-MATNR. " OBLIGATORY.
SELECT-OPTIONS : S_MTART FOR MARA-MTART NO INTERVALS NO-EXTENSION.

Now my requirement is when i execute the report by default the 1st radiobutton is selected. For this radiobutton,
i want to display only the first 3 select-options. And when the user clicks on the second radiobutton,
the parameter LIFNR should appear without pressing enter button. Again when the user clicks on
1st radiobutton the parameter field LIFNr should not appear.
Please can anybod yrpovide the code.
