You can write your own tablemodel,
i.e. use DefaultTableModel or implement AbstractTableModel.
Good luck!

Setting Background color of two columns

Hi,
I'm trying to set the background colors of two empty columns. Here's a snippet of the code.
The problem is, there is no setBackground method for TableColumn. I tried to cast it to Component but it was an invalid cast. Any thoughts?
emptyColumn3 = new TableColumn();
emptyColumn8 = new TableColumn();
emptyColumn3 = tableData.getColumnModel().getColumn(3);
emptyColumn8 = tableData.getColumnModel().getColumn(8);
emptyColumn3.setBackground(Color.gray);
emptyColumn8.setBackground(Color.gray);

Set background color when condition applied

hi,
Can anybody tell me how to set background color when condition applied.
My initial plan was to highlight a specify row(Change color) when the third column of this JTable consists of OK word.
int rowCount = table.getRowCount();
for(int i=0 ;i <rowCount ; i++)
String word = table.getValueAt(i,3).toString();
if(word.equals("Word")) {
table.setSelectionBackground(Color.red);
break;
else {
table.setBackground(getBackground());
Thanks.

Setting Row Color of the JTable

Hi,
I wanted to set the first row and first column of the JTable .
Can anybody help me in this? I read CellRendering but didn't understood when getTableCellRendererComponent(...) method get called and how it works.
I realy appreciate if anybody explains me.
Thanks,
Padmashree

Hi,
If my understading is correct, You are trying to set the color of the first column of the first row.
"Renderer" returns the component used for drawing the cell. It applies for all the cell. Method called
"GetTableCellRendererComponent" is used to configure the renderer appropriately before drawing.
So the following parameters are provided to acheive it.
table - the JTable that is asking the renderer to draw; can be null
value - the value of the cell to be rendered.
isSelected - true if the cell is to be rendered with the selection highlighted; otherwise false
hasFocus - if true, render cell appropriately.
row - the row index of the cell being drawn.
column - the column index of the cell being drawn
So to acheive your requrement, you have to do something like this.
1 - apply the required color to first cell of the first row
2 - configure in such a way that it works when the renderer reads first row and first column.
For. e.g To set the background color as Blue,
     if(row == 0) && ( column == 0){
     this.setBackground(Color.Blue);                          }else {
          this.setBackground(defaultColor);
Hope it gives a good picture.

Here i will get two outputs in same excel with different spread sheets,
now i want to set background color for headers i
ex:PARTY_ID,PARTY_NAME,AGENT_ID,TYPE_LOOKUP_CODE are the headers,in excel output i want background color as blue.
Please do need full help,its urgent req.

Hello,
open the file in Excel and save it, just to ensure that Excel writes all the additional stuff it thinks is necessary.
Now change the background colour of the header and save the file again but with a different name.
Open both files in a text editor and look at the differences. That's what you need to change in your code.
Alternatively you can use packages like xml_spreadsheet or ExcelDocumentType, both write the same file format that you use in your code and you don't have to reinvent the wheel.

Hi
A couple of things...
Thats SQL - not PL/SQL
That is not a valid SQL statement, I'm surprised its not giving an error. Please post the exact region source.
When posting code on the forum, put {noformat}{noformat} (with the curly brackets and the word code in lowercase) above and below your code like this...
{noformat}{noformat}
SELECT *
FROM emp
{noformat}{noformat}
It will then appear like this... SELECT *
FROM emp

How to set background color in JTF GRID

Is it possible to set background color in JTF GRID ?

Hello Pavo,
it's also possible to take the code from ebitar and use the expression within styleClass instead of inlineStyle.
E.g. you can define a custom style "StyleClassEmptyText" in your skin and set this styleclass if af:inputtext is empty.
By using style classes you can have the same style in the whole application and you are able to change this style on a single point(in the styleclass) for the whole application.

It's impossible, you have to use canvas instead of form to set background color

Could set background color of scrollbar?

Hy
is it possibile set background color of scrollbar?
thanks

From my experience on this - yes, setting the colour (or the Visual Attribute) of the Block object will determine the background colour of the scrollbar. As far as I can see, it doesn't affect anything else.
I've had to ensure all my Blocks have a background colour set (to r88g88b88), because if it's left as <unspecified>, then the background of the scrollbar will be transparent. In Client-Server 6i, this isn't too bad, as the scrollbar still has a visible 'edge', but in 10.1.2.0.2 WebForms, this edge isn't present, meaning the background of the scrollbar isn't visible at all, just the two ends and a disembodied drag button. Not the end of the world, but some users thought it looked funny.
