wxTreeEvent(3)

NAME
wxTreeEvent - Functions for wxTreeEvent class

DESCRIPTION

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

EVENTS

Use wxEvtHandler:connect/3 with wxTreeEventType to subscribe to events of this type.

EXPORTS

getKeyCode(This) -> integer()

    Types:
        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).

getItem(This) -> integer()

    Types:
        This = wxTreeEvent()

    Returns the item (valid for all events).

getKeyEvent(This) -> wxKeyEvent:wxKeyEvent()

    Types:
        This = wxTreeEvent()

    Returns the key event for EVT_TREE_KEY_DOWN events.

getLabel(This) -> unicode:charlist()

    Types:
        This = wxTreeEvent()

    Returns the label if the event is a begin or end edit label event.

getOldItem(This) -> integer()

    Types:
        This = wxTreeEvent()

    Returns the old item index (valid for EVT_TREE_SEL_CHANGING and EVT_TREE_SEL_CHANGED events).

getPoint(This) -> {X :: integer(), Y :: integer()}

    Types:
        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).

isEditCancelled(This) -> boolean()

    Types:
        This = wxTreeEvent()

    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:
        This = wxTreeEvent()
        Tooltip = unicode:chardata()

    Set the tooltip for the item (valid for EVT_TREE_ITEM_GETTOOLTIP events).

    Windows only.
