Keeping JTable selection

Question

I am using JTable with MULTIPLE_INTERVAL_SELECTION when I call

 int[] selectedRows = jtable.getSelectedRows();

I am getting array of selected rows indexes like 5,6,8 for eg. Now In case of error I want to maintain same selection.

I am trying

_selectionModel.setSelectionInterval(selectedRows[0], selectedRows[selectedRows.length-1]);

but it is selecting rows from 5 to 8 how can I avoid to select row number 7 which wasn't selected before?

Why don't you use just use a for loop and select each Row separate? Or isn't it possible to use the int-array directly with another method? — Leo Pflug, Feb 03 '14 at 09:39
for (int i = 0; i < selectedRowCount; i++) { table.changeSelection(selectedRows[i], 1, true, false); } How about this? — Leo Pflug, Feb 03 '14 at 09:41
Ehm also better use table.clearSelection(); before using changeSelection(). — Leo Pflug, Feb 03 '14 at 09:45
@LeoPflug its working for me in test application but not in my main application, any suggestion? — eatSleepCode, Feb 03 '14 at 12:36
Do not change things at the table(delete rows, add rows) after changeSelection is used. showing us a bigger codesnippet should do the trick :P — Leo Pflug, Feb 03 '14 at 12:38

For that purposes you can use addSelectionInterval() method instead of setSelectionInterval(). For example:

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;

public class Example  {

    public static void main(String[] args) {
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JTable t = new JTable(10,1);
        frame.add(new JScrollPane(t));

        t.getSelectionModel().clearSelection();
        t.getSelectionModel().addSelectionInterval(5, 6);
        t.getSelectionModel().addSelectionInterval(8, 8);
        frame.pack();
        frame.setVisible(true);
    }

}

Its working in test application but not in my main application any problem? — eatSleepCode, Feb 03 '14 at 12:32
