Setting Editable columns in JTable

I am trying to create a table where the first column is uneditable. I am guessing I want to use the isCellEditable method at some point? But this seems to be a query, rather than a setting. Can somebody explain how I go about making this setting?

Swing related questions should be posted in the Swing forum.
I am guessing I want to use the isCellEditable method at some point?Good guess. If you don't know how to use a method, then search the forum using the method name as a keyword to find postings that already have example of using this method. A lot faster then posting a question and hoping someone answers it.
I prefer overriding the isCellEditable method of JTable.

How to set a column in JTable non-editable?

I have a JTable, and how can I set a particular column non-editable?
Thank you.

You could create a sub class of DefaultTableModel, you pass the column number to the constructor or you add a method like setColumnEditable(0, false); to set column 0 non-editable.
You overwrite the method isCellEditable so it will return false when the column number that is passed to the method is 0 (if you want to have column 0 non-editable).

Editable Columns in JTable

I have a JTable that I want the cells in the first two columns to be NOT EDITABLE and the third column cells EDITABLE. How can this be accomplished?
Thanks

How to set different renderers to different cells in same column of JTable?

Hello Friends,
I need your help again...
Does any body knows, how to set different renderer's for different cells of same column in JTable..??
For ex.
Col1 Col2 Col3 Col4
A       A       A      A
A       A       A      B
A       A       A      C
A       A      A       D
Where A B C D would be different Renderers. I want set exactly same ,,, ie. one column with different renderer at different cell positions..
Right now i m setting renderer using statement bellow :
table.getColumnModel().getColumn(int).setCellRenderer(rederer_Instance);But with this, effect in the last renderer is applicable whole column....
Can any body help me out ?????????

Can't set custom column widths in JTable

I'm trying to set custom columns widths. They are set as I wish but then they are reset to default values (all columns have the same size). This is caused by method JFrame.setVisible(true) which invokes JTree.setWidthsFromPreferredWidths(). It can be investigated from following stack trace printed when a column being resized (see below).
How to prevent this auto width sizing?
P.S. can't override JTable.setWidthsFromPreferredWidths(); seems it's private
table = new JTable(model) {
     public void columnMarginChanged(ChangeEvent event) {
          new Exception("stack trace").printStackTrace();
          super.columnMarginChanged(event);

When I create the table I have code like this:TableColumn col = getColumnModel().getColumn(2);
col.setMinWidth(width + 4);
col.setMaxWidth((int)(width * 1.2));Works just fine for me. The setWidthsFromPreferredWidths() method will use these limits as far as I can see.

How can i make perticular row or perticular cell Editable of a JTable

Dear al,
can u help me by guiding me for the problem of...
i am having a JTable, in which a (first)column of each row is having a checkbox field.
If the checkbox is checked then and then i should able to modify the cells in that row where the checkbox is.
I have created the table with AbstractTableModel of which the isCellEditable(int row, int col) method is overwriten. Whatever return value (true/false) reflects the perticular
cells becomes editable/non-editable respectively.
but at run time...(mean the table is created now) and now i want to make the cells editable/non-editable depending on the checkbox value...
how can i implement it.........
please suggest.........
thank you.........

Editable columns in table don't select the whole row

I am new to the forums and posted this to the wrong one the first time and I am not sure how to move it so I am just reposting it here. Sorry.
I have a table with 7 columns. 2 of them are non-editable and the rest are either radio buttons or check boxes. When I click on the 2 non-editable columns, the whole row gets highlighted. When I click on any of the editable columns, the button is selected, but the whole row is not highlighted. If I made the editable columns non-editable then the whole row gets highlighted when the column is clicked on. I want the button selected and the row highlighted when the editable columns are clicked on. Here is some relevant code:

      fireTableRowsDeleted(totaldata.size()-1, totaldata.size()-1);
}I have searched forever to try to find how to do this and I can't seem to get it right. If all the radiobuttons in one column are selected and I click on one of those rows in one of those columns, then the whole row is highlighted.
Can anyone help me out?
Thanks.

Please Help!!

Here there is a JTable where 3 colums are being resized
TableColumn column1 = null;
               for (int i = 0; i < 3; i++) {
                   column1 = table1.getColumnModel().getColumn(i);
                   if (i == 0) {
                       column1.setPreferredWidth(20);
                   } else {
                        if (i == 1){
                             column1.setPreferredWidth(160);
                        else
                             column1.setPreferredWidth(80);

Hi,
In addition to setting DO_SUM = 'X' you need to specify function in H_FTYPE field. It should be set to 'AVG' in your case.
ls_fielcat-do_sum = 'X'.
ls_fieldcat-h_ftype = 'AVG.

Group feature at ALV grid with editable columns

Am I right ?
Group function by using a sorted layout is disabled while having one (or more) editable columns, isn't it ?
... or is there a possibility to use gouped rows ?

Vertical headers for columns in JTable

Hi,
I'm actually working on JTables and i'd like to set the headers of some columns to appear vertically instead of by default horizontal.
I've found some tuts or examples to set the header on multiple lines but no one to set the header vertical...
I want something like that :
before :
column1 | column2
row1 |
row2 |
and after setting header columns vertical ( with column1 and column2 the column headers of my JTable )
c | c
o | o
l | l
u | u
m | m
n | n
1 | 2
( and orientation of row headers not changed )
Thanx for your reply
Scottish

Hi,
Create you own colunm header renderer... it is actualy a cellRenderer. That cellRenderer should extends JLabel or JButton depending on what you want and you must put a paint method in it that draws the vertical text.

How to use Special value set with Column clause to display addtional column

hi
can anyone tell me
How to use Special value set with Column clause to display addtional column
how can i use FND POPID and with COLUMN clause ?

Dear Yaseen,
To get the value in formula cumulative,after you have created the formula for that particular key figure,go to edit and click on tab "calculations".
In that select overall result as 'count all values not equal to zero' and single result as 'count all values not equal to zero' .
And mark the cumulative check box underneath.
I hope you get the desired result and please do me favour .

Hide a column in JTable

Dear all,
I want to hide a column in JTable object, I already tried resize it to 0 but the effect is not good, I also cannot remove the column, since I need this column for other process.
So, any other good idea besides resizes and remove?
Thank you very much!

I have tried that too, but the column isn't hide, the size is not actually come to 0,...That's because JTable has a default minimum width of 15.... if you want to hide the column, you must set the minwidth as well. For example:
myTable.getColumnModel().getColumn(column_to_hide).setMinWidth(0);
myTable.getColumnModel().getColumn(column_to_hide).setPreferredWidth(0);;o)
