    Default Highligh row in JTabel

    hi,

    I'm using JTabel and AbstractTableModel to show data from DB.
    At the first version I simply show the data, and in this case when I click single row, this row was highlighted (the whole row).
    But later I add some changes in the colors and font- I implemented the methods prepareRenderer and isCellSelected for those changes,
    and in this version when I click in the table only the cell selected.

    The questions are why exactly this change causing this different behavior?
    And how can I achieve, easily, the behavior for highlighting all the row?

    Any help will be appreciated.

    I wonder if you're setting the cellSelectionEnabled property to true. If false, via setCellSelectionEnabled(false), then the JTable should highlight the selected row, not the cell (as long as rowSelectionAllowed is also true which I believe it is by default).

    Hi,

    Currently I'm not changing those property at all.
    I try set them in all combination - TRUE/TRUE, TRUE/FALSE, FALSE/TRUE, FALSE/ FALSE, and doesn't seem to have effect.

    however if I comment the 2 method overridden - prepareRenderer and isCellSelected, then it is highlight the row.

    import java.awt.*;
    import java.util.ArrayList;
     
    import javax.swing.JTable;
    import javax.swing.table.TableCellRenderer;
     
    public class BaseAbstractTable extends JTable
    {
    	private BaseAbstractTableModel baseTableModel;
    	private ArrayList<Boolean> fillRow_Arr;
     
    	public BaseAbstractTable(BaseAbstractTableModel p_tableModel, ArrayList<Boolean> p_fillRow_Arr)
    	{
    		super(p_tableModel);
    		baseTableModel=p_tableModel;
    		fillRow_Arr=p_fillRow_Arr;
     
     
        	//setCellSelectionEnabled(false);
        	//setRowSelectionAllowed(true);
    	}
     
    	public Component prepareRenderer(TableCellRenderer renderer,int row, int col) 
    	{  
            Component comp = super.prepareRenderer(renderer, row, col);
            if(baseTableModel.getRowElement_Map().get(row)==null)
            {
                comp.setBackground(Color.LIGHT_GRAY);
                comp.setForeground(Color.BLUE);
                comp.setFont(new Font("HELVETICA", Font.BOLD, 16)); 
            }
            else if(fillRow_Arr!=null && !fillRow_Arr.get(row))
            {
            	comp.setBackground(Color.ORANGE);
            }
            else
            	comp.setBackground(Color.WHITE);
     
            return comp;
        }
     
    	public boolean isCellSelected(int row, int col)  
    	{
    		return true;
    	}
    }
