Event macros: 

- EVT_LIST_BEGIN_DRAG: Begin dragging with the left mouse button.  
- EVT_LIST_BEGIN_RDRAG: Begin dragging with the right mouse button.  
- EVT_LIST_BEGIN_LABEL_EDIT: Begin editing a label. This can be prevented by calling :meth:`~wx.ListEvent.Veto`.  
- EVT_LIST_END_LABEL_EDIT: Finish editing a label. This can be prevented by calling :meth:`~wx.ListEvent.Veto`.  
- EVT_LIST_DELETE_ITEM: Delete an item.  
- EVT_LIST_DELETE_ALL_ITEMS: Delete all items.  
- EVT_LIST_ITEM_SELECTED: The item has been selected.  
- EVT_LIST_ITEM_DESELECTED: The item has been deselected.  
- EVT_LIST_ITEM_ACTIVATED: The item has been activated (``ENTER`` or double click).  
- EVT_LIST_ITEM_FOCUSED: The currently focused item has changed.  
- EVT_LIST_ITEM_MIDDLE_CLICK: The middle mouse button has been clicked on an item.  
- EVT_LIST_ITEM_RIGHT_CLICK: The right mouse button has been clicked on an item.  
- EVT_LIST_KEY_DOWN: A key has been pressed. :meth:`~wx.ListEvent.GetIndex`  may be -1 if no item is selected.  
- EVT_LIST_INSERT_ITEM: An item has been inserted.  
- EVT_LIST_COL_CLICK: A column (m_col) has been left-clicked.  
- EVT_LIST_COL_RIGHT_CLICK: A column (m_col) (which can be -1 if the click occurred outside any column) has been right-clicked.  
- EVT_LIST_COL_BEGIN_DRAG: The user started resizing a column - can be vetoed.  
- EVT_LIST_COL_DRAGGING: The divider between columns is being dragged.

:meth:`~wx.ListEvent.__init__`                                                   Constructor.
:meth:`~wx.ListEvent.GetCacheFrom`                                               For  ``EVT_LIST_CACHE_HINT``   event only: return the first item which the list control advises us to cache.
:meth:`~wx.ListEvent.GetCacheTo`                                                 For  ``EVT_LIST_CACHE_HINT``   event only: return the last item (inclusive) which the list control advises us to cache.
:meth:`~wx.ListEvent.GetColumn`                                                  The column position: it is only used with  ``COL``   events.
:meth:`~wx.ListEvent.GetData`                                                    The data.
:meth:`~wx.ListEvent.GetImage`                                                   The image.
:meth:`~wx.ListEvent.GetIndex`                                                   The item index.
:meth:`~wx.ListEvent.GetItem`                                                    An item object, used by some events.
:meth:`~wx.ListEvent.GetKeyCode`                                                 Key code if the event is a keypress event.
:meth:`~wx.ListEvent.GetLabel`                                                   The (new) item label for  ``EVT_LIST_END_LABEL_EDIT``   event.
:meth:`~wx.ListEvent.GetMask`                                                    The mask.

:meth:`~wx.ListEvent.IsEditCancelled`                                            This method only makes sense for  ``EVT_LIST_END_LABEL_EDIT``   message and returns ``True`` if it the label editing has been cancelled by the user (:meth:`~ListEvent.GetLabel`   returns an empty string in this case but it doesn't allow the application to distinguish between really cancelling the edit and the admittedly rare case when the user wants to rename it to an empty string).
:meth:`~wx.ListEvent.SetCacheFrom`
