Question

I have this piece of code:

listTable.addMouseListener(new MouseAdapter() {
                 public void mouseClicked(MouseEvent e) {

                  if (e.getClickCount() == 1) {
                  JTable target = (JTable)e.getSource();

                  int row = target.getSelectedRow();
                  int column = target.getSelectedColumn();

                  String title = listTable.getValueAt(row, column).toString();
                  String duration = listTable.getValueAt(row, column+1).toString();
                  String genre = listTable.getValueAt(row, column+2).toString();
                  String actor = listTable.getValueAt(row, column+3).toString();
                  String director = listTable.getValueAt(row, column+4).toString();
                  //String rentable = listTable.getValueAt(row, column+5).toString();
                  //String synopsis = listTable.getValueAt(row, column+6).toString();

                  txtTitle.setText(title);
                  txtDuration.setText(duration);
                  txtGenre.setText(genre);


                  }
                });

Which enables me:

• When a row is selected it passes the values in the columns to JTextBoxes.

However, when I don’t click the first column by default, the selection gets garbled up. For example, if I don’t click on the “Title” column first and click on the “Duration” column, it puts the duration in txtTitle and the others are also mixed up.

How do I add a piece of code that when a row is selected, it default-selects the first column ?

This is a screenshot of what happens:

Answer 1

Rather than forcing selection of column why not always extract values based on known columns?

For example you can replace:

String title = listTable.getValueAt(row, column).toString();

with:

String title = listTable.getValueAt(row, 0).toString();

If you provide ability to reorder columns then you can instead try table.getModel().getValueAt(convertRowIndextoModel(row), 0);
