Disable a checkbox in jtable

[pink123]

In my Jtable i have a column which is a boolean type. I need to disable some of the cells in this column based on a condition.
It would be gud if the color of those cell which are to be disabled is different.
In the tablemodel ,I have returned a boolean in the getColumnClass for the particular column and in the isCellEditable method retuen false for that particular column.By doing this I am not able to click on the checkbox,but I want these cells to look diffrent so that the user acn differentiate.


How it is possible?

Thanks,

You would need to create a custom renderer. Copy the "BooleanRenderer" class from the JTable source code. You would then need to add a line of code like:

setEnabled( table.isCellEditable(row, column) ? true : false );

Thanks a lot for your reply.
I am not aware how to create a cellrenderer?
Can you please explain or elaborate on your point.

Thanks,

Read the JTable API and follow the link to the Swing tutorial on "How to Use Tables" where you will find a section that explains the concept of renderers.

Thanks for help,I had just one more doubt,i have a tableListener on my table .
If I use a BooleancellRenderer for a particular column ,will the tableListener still work?

Thanks,

Why don't you try it and see?

I don't know what a "tableListener" is.

Why don't you try it first? Then if you have a problem you can post a question.

thanks,
I tried creating a class but my checkbox is not disabled even when the cellEditable is false
Following is a sample code

public class TestBooleanRenderer extends JCheckBox implements TableCellRenderer
{

public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
{
setEnabled( table.isCellEditable(row, column) ? true : false );
return this;
}
}

and called it in view class as

table.getColumnModel().getColumn(10).setCellRender er(new TestBooleanRenderer () );

I put some print statements inside myBooleanRenedere i,it is not called.What mistake I am doing?

Thanks,
