JTable: aligning particular cells

Assuming that the programmer does not know beforehand the number of rows a JTable will have, how can he/she go about right-aligning all the cells of a particular column (say the 3rd and 4th)?
Would I need to use TableCellRenderer? And if so, how do I go about doing this?
Cheers!

I think you will be good with the other post, but anyway...
What I meant was that if the column to be right-justified was of the same type as a column that should not be right-justified then you cannot use the table.setDefaultRenderer method. Then you must either add the rederer to a specific column or in the rederer use the correct component depending on the column passed.
If only the columns to be right-justified are of that type then you are good and can do the following.
table.setDefaultRenderer (Integer.class, myRenderer);
table.setDefaultRenderer (Double.class, myRenderer);

Setting Focus to a particular cell in JTable

Hi, can i know how to set the focus to a particular cell in JTable.
Say I have a table with 2 rows and 10 columns. The focus now is at position (1, 9) which is the last cell in the table. But I want to set the focus to (1, 3). How can i achieve this ? Pls help. Thanks

OK. It's partially working. The right methods to use are setRowSelectionInterval and setColumnSelectionInterval. Jeanette was right. Mine didn't work because of a thread issue. I put the those two methods in a block such as:
SwingUtilities.invokeLater(new Runnable(){
public void run()
table.setRowSelectionInterval(tblLineItem.getRowCount()-1,
table.getRowCount()-1);
table.setColumnSelectionInterval(0,0);
Then it worked.
But after I finished editing the first cell of the newly created row and press ENTER, the selection went back to the cell that's next to the originally editing cell on the first(old) row, instead of staying at the current row and going to the second cell.
Can anybody shed a light on what I'm missing?

How to insert checkbox at a particular cell in jtable

hello,
I am a user of jdeveloper using jclient/swing .
question:
i am using jtable. i want that whenever i click on a specified cell then text at that particular cell get clear and a checkbox inserted in that cell . whenever i click on that checkbox i.e check the checkbox,
again a text is inserted in that cell.
thank you

Did you ever get this to work? If I bind a JCheckbox to my attribute and add the checkbox to my JClient panel, the attribute value is properly bound to the checkbox with everything working correctly. Adding the checkbox as the TableCellEditor for the column doesn't work.
Also, the link to using a Combobox as a table cell editor works, but the link doesn't tell where to donwload the sample code from. Doesn't anyone know the link?

How to disable a particular cell in JTable ?

I having a problem on how to set disable a particular cell in JTable. At the first place to load the JTable, I want to set some of the cell to disabled, it only will run at the first time, is there anyway to do it ?

This is the function that disable/enable cells in JTables.
Are you looking for this?
public boolean isCellEditable(int row, int col)
if(((new Integer((String)(getValueAt(row,0)).toString()).intValue()>9))&&(col==1))
    return true;
if(row!=4&&col!=5)
    return true;
return false;
     this metod belong to the TableModel function
and what I gave you is only an example of what you can do with it.
if it return false it disable and if true it enable the cell...but I think this you allready know!

Change particular cell color when finised editing and when lost focus

Hi, i want to create a table which its particular cell can change its color automatically to red if the value in cell in column in two is smaller than column cell value in column 1 when user finish typed a value or if the cell has lost focus. I've wrote a code for the renderer but how should I use action, KeyListener or MouseLister or both
* File ColouredCellRenderer.java
import java.awt.Color;
import java.awt.Component;
import javax.swing.JTable;
import javax.swing.table.TableCellRenderer;
import javax.swing.table.DefaultTableCellRenderer;
public class ColouredCellRenderer extends DefaultTableCellRenderer implements TableCellRenderer{
    private Object col1Value, col2Value;
    public ColouredCellRenderer(Object args1, Object args2){
        this.col1Value = args1;
        this.col2Value = args2;
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
          return super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
     protected void setValue(Object v){
          super.setValue(v);
        if((col1Value != null) & (col2Value != null)){
            int x = Integer.parseInt(col1Value.toString());
            int y = Integer.parseInt(col2Value.toString());
            if(x > y){
                this.setBackground(Color.RED);
            else{
                this.setBackground(Color.GREEN);
}

All you should need is the cell renderer to achieve that effect. Whenever the table needs to render a cell it will call the method
getTableCellRendererComponent(...);This method in turn returns a component showing what the cell should look like. The DefaultTableCellRenderer extends JLabel, so you are meant to customize the label (based on parameters that were passed) and return this* at the end of the method.
public Component getTableCellRendererComponent(...) {
         return this;
}This one label is used to render all the cells of all the columns that the cell renderer is assigned to. Since you want some cells too be red, you should call setBackground(Color.red)+ when the conditions are appropriate or null otherwise.

Is there any way to tell which formulas a particular cell is in, reverse look-up style? That is, is there a way to search somehow for which formulas in a sheet contain a particular cell in them without opening all of them up? If not, it would be nice

Is there any way to tell which formulas a particular cell is in, reverse look-up style? That is, is there a way to search somehow for which formulas in a sheet contain a particular cell in them without opening all of them up? If not, it would be nice.
I'm fixing a Numbers document that I use in business daily that's become overly complicated, but while I want to clear/delete a number of cells in it to clean it up, I'm not sure if those cells are being used as source for other formulas on the page. I don't have to open all my formulas one by one to see if that cell is in there, do I?! That'd be a huge amount of work if I wanted to eliminate say 10 cells to search each formula on the page to see if it is in there or watch all the cells when I delete that cell to see if the numbers change! There's got to be an easier way! Right click doesn't seem to be any help.
I don't want to damage my daily tool to make it cleaner and reorganize it. Is there really no way to do a reverse look-up of which formulas a particular cell is in?! Any time I click on a formula it highlights all the CELLS in that formula. Why can't I (or can I?) do the reverse and see all the FORMULAS that contain a particular cell?
As a Numbers document ages or gets used frequently, you can sometimes forget which cells are tied to which formulas. You just look for the results of your formulas. Would be a nice thing to be able to do. Thoughts? Work-arounds? Answers?

Answer would be no unless application provided such feature. Numbers does not as far as I know.
Note that even if you have complete list of formulae used in a table, identifying formulae referencing any given cell is not simple.
E.g., cell T20 is referenced not only in
=T20+1
but also in
=SUM(T)
=SUM(20:20)
=SUM(S19:U22)
=OFFSET(S1,19,1,1,1)
=INDIRECT("T"&(10*2))
In order to identify such formula, we have to actually evaluate it to see if it references the given cell. Especially such formula as OFFSET() and INDIRECT() may not be found by static parser because their parameters can be dynamic.
Sorry to be the bearer of bad tidings.

HOW TO GET VALUE OF A PARTICULAR CELL IN ALV GRID

I HAVE 2 ALV GRID. IWANT WHEN I DOUBLE CLICK ON ANY PARTICULAR CELL OF FIRST GRID I WILL GET THE VALUE DISPLAYED ON THAT PARTICULAR CELL.
THANKS IN ADVANCE

Hi,
If you are using a class alv, you only need to create a local class to control event and, before setting the screen to present the alv, you need to assign the class as a handler, like this:
    CREATE OBJECT event_handler.
    SET HANDLER event_handler->double_click FOR alv_grid.
This event handler was defined before like below and a object was created for it:
CLASS cl_event_handler DEFINITION.
PUBLIC SECTION.
    METHODS double_click FOR EVENT double_click OF cl_gui_alv_grid
      IMPORTING e_row e_column.
ENDCLASS.                    "cl_event_handler DEFINITION
Then you need to implement this class, creating the method double click and do a READ TABLE to the itab you presented in the alv to recover the data, like this:
    READ TABLE itab INTO wk_itab
      INDEX e_row-index.
The e_row structure was sent to the method by the handler, setting it with the line index that you double clicked in the alv. After that, you can manipulate the data that you selected in your internal table to generate the data to the other ALV.
Best Regards,

Set back ground color to a particular cell in table view

hi,
 iam working on a jspDynpage and have a htmlb table view for which i need a way to set back ground color to a particular cell in table view, the color has to be set based on a value..is there a way to do it without using an iterator...well iam using a cellRenderer for the table but cant find a way to set the colors...if anyone does have a way please do reply...regards

You can mention the color in textview as well as Label as follows:
 <htmlb:textView text = "My Textview"
 design = "EMPHASIZED" />
 <htmlb:label for = "MyLabel"
 text = "Label "
 encode = "false"/>

How to disable a particular CELL in matrix?????

Hi All,
I have a doubt regarding the matrix.In my matrix the first column is a combobox it has a,b,c items....so if i select 'a' the remaining 'b' & 'c' columns should get disabled....previously iam able to disable the 'b' & 'c' columns but it's disabling the total 'b & 'c' columns in my matrix.....i just want to disable the particular cell based on the combobox selection....can we disable a particular cell in matrix.....
regards,
shangai.

Shangai,
here were many threads about this in last month. Try to search in history.
BTW, the particular cell cannot be disabled (only whole column), but you could make system, that the cell is enabled but you cannot click on it (when user clicks on the cell, set bubbleeevnt to fasle).

alv_layout-coltab_fieldname = 'TABCOLOR'.
* For each row in data_tab
REFRESH: lt_color.
CLEAR: lt_color.
lt_color-color-col = 6.
lt_color-color-int = 1.
lt_color-fname = FIELD1'.
APPEND lt_color.
lt_color-color-col = 2.
lt_color-color-int = 0.

How to display an image in particular cell editor

Hi All,
I want to display an image as the background for the table cell.
I searched in sdn and found the solution only for link to action.
I have created a dynamic table and if i click on apply button one more row is getting added according to my requirement.
I want to differentiate this row from rest. So I need to display image for the last row in the table which is added newly.
Can anyone suggest the procedure for adding an image in a particular cell editor along with the table data?
Hope I am clear with my requirement.
Pls suggest.
Regards,
subashini

Hi,
IF iam not wrong then for some rows u need to show text data and for some rows u need to show image data.
follow the following steps.
1. In ur table add cell editor of type Image.
2.Create a value node with one more than required attributes.
3.Suppose if need to show only one column then i will create
value node with two attributes.One attribute will be for text
data and one will for Image.
4.now access ur table cell editor dynamically.For image type
cell editor we need to play only with two properties source
and alt.Bind this alt property of editor wid that attribute which u
need use for text data and source wid that attribute which u
need to use for image.
5. Now suppose I need to show text data then
I will create one element of that value node.In case of Image
type cell editor source property is given prefrence over alt
property.
set attribute which is bound to alt to the actual text data
i.e setText("Actual text data");
and set attribute which is bound to source to some dummy
image name
i.e setImage("dummy.gif");
add this to node.
during execution as source property of editor is bound to
Image attribute of node which in turn is set to dummy value it
wont find actual source and will set Image cell editor with
watever is bound to alt property which in turn set with actual
text value..
6. Now suppose I need to show Image data then
I will create one element of that value node.In case of Image
type cell editor source property is given prefrence over alt
property.
set attribute which is bound to alt to blank value
i.e setText("");
and set attribute which is bound to source to some Actual
image name
i.e setImage("Image.gif");
add this to node.
during execution as source property of editor is bound to
Image attribute of node which in turn is set to Actual image file
it will set Image cell editor with that image name and wont look for alt property.
Copy all ur images in src->mimes->components->ur package
