Functions for wxTreeEvent class
A tree event holds information about events associated with wxTreeCtrl
objects.
To process input from a tree control, use these event handler macros to direct
input to member functions that take a wxTreeEvent argument.
See: wxTreeCtrl
This class is derived (and can use functions) from: wxNotifyEvent
wxCommandEvent wxEvent

subscribe to events of this type.

Returns the key code if the event is a key event.
Returns the key event for EVT_TREE_KEY_DOWN events.
Returns the label if the event is a begin or end edit label event.
Returns the old item index (valid for EVT_TREE_SEL_CHANGING and
EVT_TREE_SEL_CHANGED events).
Returns the position of the mouse pointer if the event is a drag or menu-context event.
Returns true if the label edit was cancelled.
Set the tooltip for the item (valid for EVT_TREE_ITEM_GETTOOLTIP events).

Functions
-spec getItem(This) -> integer() when This :: wxTreeEvent().
Returns the item (valid for all events).
-spec getKeyCode(This) -> integer() when This :: wxTreeEvent().
Returns the key code if the event is a key event.
Use getKeyEvent/1 to get the values of the modifier keys for this event (i.e.
Shift or Ctrl).
-spec getKeyEvent(This) -> wxKeyEvent:wxKeyEvent() when This :: wxTreeEvent().
Returns the key event for EVT_TREE_KEY_DOWN events.
-spec getLabel(This) -> unicode:charlist() when This :: wxTreeEvent().
Returns the label if the event is a begin or end edit label event.
-spec getOldItem(This) -> integer() when This :: wxTreeEvent().
Returns the old item index (valid for EVT_TREE_SEL_CHANGING and
EVT_TREE_SEL_CHANGED events).
-spec getPoint(This) -> {X :: integer(), Y :: integer()} when This :: wxTreeEvent().
Returns the position of the mouse pointer if the event is a drag or menu-context event.
In both cases the position is in client coordinates - i.e. relative to the
wxTreeCtrl window (so that you can pass it directly to e.g.
wxWindow:popupMenu/4).
-spec isEditCancelled(This) -> boolean() when This :: wxTreeEvent().
Returns true if the label edit was cancelled.
This should be called from within an EVT_TREE_END_LABEL_EDIT handler.
-spec setToolTip(This, Tooltip) -> ok when This :: wxTreeEvent(), Tooltip :: unicode:chardata().
Set the tooltip for the item (valid for EVT_TREE_ITEM_GETTOOLTIP events).
Windows only.
