Change JTable's row color on row selection

Hello!
Everywhere I've looked they're only explaining how to draw rows in different colors WHEN THE TABLE IS BEING CREATED, via prepareRenderer.
But that is not what I am looking for. What I want is to actually change the row's color after the table has been drawn/rendered/whatsoever. For instance, when the user clicks on that row. The default behaviour is for the row to become blueish, but, when the user selects another row, the first selected row turns back to white. I would like to prevent that from happening. I want the row to become FIRE RED when the user clicks on it, and I want the row to remain like that for good, even when the user selects a different row. Do I make any sense here? :-)
Thank you for your time and future suggestions.

Everywhere I've lookedApparently you didn't look in the Swing forum, because thats where Swing related questions should be posted.
but how do I assign a cell renderer to an entire row/table ?The easiest way is to use the prepareRenderer(...) method you have already found. My "TablePrepareRenderer" class (which you can find by searching the Swing forum) shows you how to do this.
You will note that the color of the row is determined by data in the table. So all you need to do is add another column in the TableModel that contains the information you need to determine the row color. That column can be removed from view in the table by removing the TableColumn from the TableColumnModel.

Want robust solution for alternating row color, resetting every group

I would like a solution for displaying an alternating row color for my detail rows that resets every group, so that row 1 is always gray.
Our Crystal designer provided this code to me:
@rowcnt formula, suppressed, placed in Detail row:
Shared numbervar rowcnt;
rowcnt := rowcnt + 1;
@resetrowcnt, suppressed, placed in Group row:
Shared numbervar rowcnt;
rowcnt := 0;
Formatting formula, placed in Color in Detail > Section Expert:
Shared numbervar rowcnt;
if Remainder(rowcnt, 2) <> 0 then
color(241,241,241)
else
crWhite
This was working fine for me.
However, it is suddenly not working in one of my reports.
The report does happen to have two groups (rowcount.png).
When the report is run, all rows are colored (rowcount02.png).
This report was previously working fine! I'm not sure what changed.
In any case... surely there must be standard code to do this very standard formatting.
I would be very grateful if someone could post some robust code to accomplish the following:
REPORT DATA IN DETAIL ROW, ALTERNATE ROW BANDING:
- Data in Detail row displays alternating row colors
- Odd rows are always shaded, even rows not
- Banding resets every group / does not continue pattern from previous group
REPORT DATA IN GROUP ROW, ALTERNATE ROW BANDING:
Some of our reports place row data in a group row (just the way it happened).
If you could also modify your code in this case.
Thank you!

Hi Abhilash/Sastry, since I'm going to switch to Sastry's formulas, could you please confirm correctness of the following. I can't actually run this report, I can only provide it to our London office, bit of a lag for testing.
@resetrowcnt:
Whileprintingrecords;
Numbervar cnt:=0;
@rowcnt:
Whileprintingrecords;
if {HedgeDetails.StrategyID} <> previous({HedgeDetails.StrategyID}) and
{HedgeDetails.DealID} <> previous({HedgeDetails.DealID}) then
Numbervar cnt:=cnt+1;
Details section (Suppress):
not(OnFirstRecord) and
{HedgeDetails.StrategyID}=previous({HedgeDetails.StrategyID}) and
{HedgeDetails.DealID}=previous({HedgeDetails.DealID})
Please note: Suppress checkbox is selected AND the above formula is entered.
Details section (Color):
Whileprintingrecords;
Numbervar cnt;
if cnt mod 2 <> 0 Then color(241,241,241) else crwhite

Different color of row

Hi experts,
I need to change the color the last row of my table with a different color. How can I do this?
TKS a lot in advance

HI,
For coloring your rows follow this approach :
1.Create a context attirbute for CELL_DESIGN of type WDUI_TABLE_CELL_DESIGN to the node to which the table is bound.
2. Bind this attribute to the CELL_DEISGN property of all the columns.
3. Get the no of rows in table.
4. When last row is selected, change the value of cell design attribue.
Sample Code :
lt_table - table with all data which is to be binded with table.
n - type I.
lv_tabix - type I.
ls_table - work area .
describe lt_table lines n.
loop at lt_table into ls_table . "This table is bound to node
lv_tabix = sy-tabix.
if lv_tabix = n.
ls_table-cell_design = CL_WD_TABLE_COLUMN=>E_CELL_DESIGN-BADVALUE_DARK
modify lt_table from ls_table index lv_index.
ENDIF.
endloop.
Bind the table to the node.
For possible values for the color please check http://help.sap.com/saphelp_nw70/helpdata/en/45/0ef14d9d942462e10000000a1553f7/frameset.htm

Conditional alternating row colors

Hello
I have a report of companies an their country which is ordered by the column country. I'd like to have a alternating row color for every new country and not for every new row as it is in custom settings.
Is that possible? How can I do that?
Regards Felix
Edited by: Felix on 21.09.2011 12:33

Hi Scott
sorry, I still not quite understand how to do, because which row must be colored depends on the number of countries in the database and alphabetic order of the countries.
For example I show you only the country row of an example report and its row color as it should be right of it (because you cannot color text in this forum):
[Country Row] [Row color]
Albania light blue
Albania light blue
Albania light blue
Albania light blue
Andorra light green
Andorra light green
Andorra light green
Andorra light green
Argentina light blue
Australia light green
Australia light green
Australia light green
Once some data rows are inserted with a new country it should look like this
[Country Row] [Row color]
Albania light blue
Albania light blue
Albania light blue
Albania light blue
Algeria light green (new data)
Algeria light green (new data)
Algeria light green (new data)
Andorra light blue (color switched)
Andorra light blue (color switched)
Andorra light blue (color switched)
Andorra light blue (color switched)
Argentina light green (color switched)
Australia light blue (color switched)
Australia light blue (color switched)
Australia light blue (color switched)
Now the row color of rows beneath Algeria changed (in order to keep the alternating row color alternating)
I hope I now pointed out my problem more clearly.
Thanks

The chart colors are being referred to *'palette.cxml'* file in these directories
BI_HOME\web\app\res\s_oracle10\chartsupport
BI_HOME\oc4j_bi\j2ee\home\applications\analytics\analytics\res\s_oracle10\chartsupport
you can change to your custom colors.

Hi Kiran,
      After setting the theme, you will have to change the following property in theme editor.

a) Background Color of Primary Selection
b) Background Color of Secondary Selection
    I hope this helps.

Changing JTable Row Color OnMouseOver

Hello everybody,
is it possible to change JTable Row Color when Mouse passes over it ??
THanks!

Yes...
You have to override the table cell renderer and set the color of the rows based on flag.
The flag can be turned on/off in a mouse motion listener of the table.

JTable set single row color

I have alternating colors for my jtable, and when a row is selected i pop up another window and clear the selection. i want to change the color of all selected rows, but if i dont clear the selection, it doesn't allow me to re-open the same record because of the way the selectionListener works. so basically i dont want to mark a row as selected, i jus want to change its color. anyone know how to do this?

looks promising.. i'm going to give it a shot. why dont they just have a method like.. table.setRowColor (rowIndex), because im implementing a selectionlistener, so i already know the rowIndex that was selected, jus have to change its color. maybe coz that would be tooo easy lol. thanks

How can i set color some rows in jtable

hi all,
i have table with two cols one is id and other name
i have array of id, i want set color for only those rows in an array
i tried with the following code but only one row is seting why it is not setting
the other rows? or this is the worg way what i did?
     model      = new DefaultTableModel(data, header);
        table          = new JTable(model){
             int mostUsedCols[] = 151,80,185,90,88,95,137,152,153,181,178,179,180,107};
             public Class getColumnClass(int column)
                    return getValueAt(0, column).getClass();
               public Component prepareRenderer(TableCellRenderer renderer, int row, int column)
                    Component c = super.prepareRenderer(renderer, row, column);
                           int id = Integer.parseInt(tblLedgerAccounts.getModel().getValueAt(row, 0).toString());
                           for(int j=0; j<mostUsedCols.length;j++){
                                c.setBackground( id == mostUsedCols[j] ? Color.LIGHT_GRAY : Color.WHITE );
                    return c;
               }help me to solve this problem

hello,
thanks,
i have table 2 cols(say for ex) 1st column is name and other one is
id, and i have some array of id's, i need to set the color for these rows
and remainings rows are defalut color (white).
I doubt that you need the
else
c.setBackground( Color.WHITE );if i did't set like this the entire table get gray.
>
since the color should be set to the default by the
super.prepareRenderer(...) method. In fact this code
would override the default row selection coloring.
But maybe I don't understand your requirement. You
notice my original example always to check to make
sure the row is not selected before changing the
background color.here is the demo, i comment this line what will happen c.setBackground( Color.WHITE );
if not doing right than suggest me.

Color a row in JTable according to specific column value

I'm having problem setting row color according to specific values set in listData. Color values are also stored inside the listData. Each row has a specific color value assigned to it(either black or blue).
ColorRenderer is called from table.setDefaultRenderer(Object.class, new ColorRenderer(listData))
The color values are passed through to ColorRender constructor but not to the getTableCellRendererComponent() method.
Here is my code. Any help is much appreciated.
class ColorRenderer extends DefaultTableCellRenderer {
Color[] colors;
public ColorRenderer(ListData[] listData) {
if (listData != null) {
for (int i=0; i<listData.length; i++) {
     if (listData[i] != null) {
     colors = new Color[listData.length];
     colors[i] = listData.getForegroundColor();
     System.out.println(colors[i].toString());
else System.out.println("null listData");
public Component getTableCellRendererComponent (JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
JLabel c =(JLabel)super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
c.setOpaque(true);
System.out.println("colors.length: " + colors.length);
for (int i=0; i<colors.length; i++) {
if (colors[i] != null) {
System.out.println("colors["+i+"]: " + colors[i]);
c.setForeground(colors[i]);
} else c.setForeground(Color.black);
return c;

Well, first of all, you didn't use the code tokens for your posting. Second, this source won't even compile how you have it. But anyway...
If you want to change the color of the cell based on the row, assuming you have a matching color in your color list for each row, in your getTableCellRendererComponent() method, just do something like this.
c.setForeground( colors[row] );
