wxTreeEvent - 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
wxWidgets docs: wxTreeEvent
Use wxEvtHandler:connect/3 with wxTreeEventType to subscribe to events of this type.

getKeyCode(This) -> integer()
Types:
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).
getItem(This) -> integer()
Types:
Returns the item (valid for all events).
getKeyEvent(This) -> wxKeyEvent:wxKeyEvent()
Types:
Returns the key event for EVT_TREE_KEY_DOWN events.
getLabel(This) -> unicode:charlist()
Types:
Returns the label if the event is a begin or end edit label event.
getOldItem(This) -> integer()
Types:
Returns the old item index (valid for EVT_TREE_SEL_CHANGING and EVT_TREE_SEL_CHANGED events).
getPoint(This) -> {X :: integer(), Y :: integer()}
Types:
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).
isEditCancelled(This) -> boolean()
Types:
Returns true if the label edit was cancelled.
This should be called from within an EVT_TREE_END_LABEL_EDIT handler.
setToolTip(This, Tooltip) -> ok
Types:
Set the tooltip for the item (valid for EVT_TREE_ITEM_GETTOOLTIP events).
Windows only.
