Hello.

I have a problem when I'm programming a special subtitle (SubRip/srt)
editor in Java.
I use a JTable (referred to as "table" in the code below) and when the
user presses Shift+Enter the table should select row n+1, where n is the
currently selected row. Ctrl+Enter does the opposite, selects row n-1.

The problem is that the code for Shift+Enter doesn't work and my
co-students at my university don't understand why either! Ctrl+Enter
works like a charm, only Shift+Enter does nothing!

Debugging showed me that if I program it to select n+2 (!) it does just
what I want, with the exception that it will never select the last row
of the table. It will disregard it and select an imaginary row outside
of the table.

Code follows:

public void keyPressed(KeyEvent e) {
    [...]
    //selmodel is the ListSelectionModel of the JTable.
    //mod is the String representation of the modifier keys pressed.
    //table is the JTable.
    else if ((mod.equals("Shift") || mod.equals("Ctrl")) && e.getKeyCode()
== KeyEvent.VK_ENTER) {
       int selectedrow = table.getSelectedRow();
       if (selectedrow != -1) {
        ListSelectionModel selmodel = table.getSelectionModel();
        if (mod.equals("Shift")) {
           if (selectedrow + 1 < table.getRowCount()) {
            selmodel.setSelectionInterval(selectedrow + 1,selectedrow + 1);
           }
        } else if (mod.equals("Ctrl")) {
           if (selectedrow > 0) {
            selmodel.setSelectionInterval(selectedrow - 1,selectedrow - 1);
           }
        }
       }
    }
    [...]
}

Looking forward to your replies.
