When clicking in a Table, how do I determine which Column was clicked? [message #453059]

The oddity of Table is that it is row-centric. From getSelection() I can
determine the row clicked, but how do I know which column was clicked?

Thanks in advance.

I think there may be a snippet; but in any event, add a MouseListener to yor table, and:

public void mouseDown(final MouseEvent event) {
final Rectangle clientArea = _table.getClientArea();
final Point pt = new Point(event.x, event.y);

_row = _table.getTopIndex();
boolean visible = true;

while (visible && _row < _table.getItemCount()) {
final TableItem item = _table.getItem(_row);

for (_column = 0; _column < _table.getColumnCount(); ++_column) {
final Rectangle rect = item.getBounds(_column);
if (rect.contains(pt)) {
return; // to leave _column, _row correct
}
visible = rect.intersects(clientArea);
}
++_row;
}
}

HTH,
Paul

A slightly better version can be found attached to this bug in short you
only have to check the selected rows and not all rows as done in the
solution in this thread.

MM -- good, that's much more efficient in large tables. And works with right-click too (to pop up a
row-dependent menu, e.g.).

Thanks,
Paul
