Question

My table has 4 columns, and I only want column 1 to be allowed to be clicked. Also, this code also allows the LEFT mouse button to be used, I only want the RIGHT button.

    private void jTable1MouseClicked(java.awt.event.MouseEvent evt) {
    // TODO add your handling code here:
    int iCol = jTable1.getSelectedColumn();

    if(iCol == 1 && evt.getModifiers() == InputEvent.BUTTON3_MASK)
    {
        if(evt.getClickCount() == 2)
        {
            int iRow = jTable1.getSelectedRow();

            File iFile = new File(jTable1.getValueAt(iRow, iCol).toString());

            String iPath = iFile.getAbsolutePath();
            File iDir = new File(iPath.substring(0, iPath.lastIndexOf(File.separator)));

            if(Desktop.isDesktopSupported()) {
                try {
                    Desktop.getDesktop().open(iDir);
                } catch (IOException ex) {
                    Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex);
                }
            }
        }
    }
}

I’m sorry if this question turned out as 2.

Answer 1

Concerning the clicking only of a specific column:

1. create the table using you own model.

final JTable table = new JTable( new MyTableModel(data, columnNames));

2. create the new model overriding the function you need (i.e. isCellEditable)

public class MyTableModel extends DefaultTableModel {

    private static final long serialVersionUID = -8422360723278074044L;

    MyTableModel(Object[][] data, Object[] columnNames )    
    {
      super(data,columnNames);
    }

    public boolean isCellEditable(int row,int cols)
     {
       if(cols==1 ){return true;}
          return false;                                                                                    
     } 
}
