Problem in row selection in JTable

[simmi]

Hi,

I have a Jtable in my application. For its cell rendering I have created a class which extends DefaultTableCellRenderer and overridden the method getTableCellRendererComponent. I am trying to change the background color of a particular column based on its value. But after doing that when I select a row its selection is not visible to me. Row is getting selected as the action on row selection is working properly but selection is not visible to me(selected row is not getting highlighted).


public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int col) {
Component comp = super.getTableCellRendererComponent(table, value,
isSelected, hasFocus, row, col);
TableModel fm = table.getModel();
if(col == 5 &&
((fm.getValueAt(row, col).toString().trim()).equals("abc"))){
comp.setBackground(Color.LIGHT_GRAY);
}
else{
comp.setBackground(Color.WHITE);
}
return comp;
}

This seems to be happening because of "comp.setBackground(Color.WHITE);" in else condition. But if I remove else condition then background color of all the columns after 5th column of first row gets changed. Color of viewport of Jscrollpane of Jtbale is WHITE so I am setting the color to white in else condition.
What should I do to see the selection.

Thanks in Advance,
Simmi

Did you notice that one of the parameters to the method you are overriding is boolean isSelected? Make good use of it.

Yeah...I used if(!isSelected) and it worked.

Thanks

FYI. getTableCellRendererComponent() returns the same object by default. Therefore, if you modify the object, it will stay modified. JTable does this for efficiency.
