GetColClicked( event ) -> int Column number of mouse click.
Get ObjectListView() column the user single-left-clicked the mouse in.
You can use the column number to set the modelObject's attributes
without removing, re-adding, resorting the items in the OVL.
This event handler is often bound to the event handler of the
wx.EVT_LIST_ITEM_SELECTED event. Other events may be needed for
the column's labels - the labels visually naming a column.
This assumes the OLV.LayoutDirection() is LTR.
