How to get Icon from JTable

Question

I have changed the cell render in JTable to show image instead of text using the following code:

base_table.getColumnModel().getColumn(3).setCel         


        

Answer 1

below is the correct image renderer class.

class SimpleCellRenderer extends DefaultTableCellRenderer{



    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) 

    {
         Component cell = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row,
               column);
      ((JLabel)cell).setIcon((Icon)value);
      ((JLabel)cell).setText("");
      ((JLabel)cell).setHorizontalAlignment(JLabel.CENTER);

      if (isSelected) {
         cell.setBackground(Color.white);
      } else {
         cell.setBackground(null);
      }
      //((AbstractTableModel)table.getModel()).fireTableCellUpdated(row,column);

      return cell;
   }


    }

below is the method from where everything gets filled automtically. private void formWindowOpened(java.awt.event.WindowEvent evt)

{                                  
        // TODO add your handling code here:

        fillIcon();  
    } 

   public void fillIcon() {
        int i,j,rowValue,colValue;
         int cols= student.getColumnCount();
         int rows=student.getRowCount();

         for(i =0 ;i
