KeyListener in a JTable makes row deletion difficult

[jonasf...@yahoo.se]

Hello all,

I'm struggling with this code snippet. A selected row in a table is to
be deleted when the delete key is pressed. The row deleted turns out to
be the row BELOW the one selected.
Running exactly this code from a button instead (no key listener) gives
correct behaviour.

I cannot figure out why it does this. Any help appreciated.

table.addKeyListener(new KeyAdapter() {
public void keyReleased(KeyEvent e) {
int c = e.getKeyCode();

if (c == KeyEvent.VK_DELETE) {
int[] index = table.getSelectedRows();
e.consume();

for (int i=index.length -1; i >= 0; i--)
tableModel.removeRow(index[i]);

}
}
});

Thanks
/Jonas, Gothenburg, Sweden
