A tree control presents information as a hierarchy, with items that may be expanded to show further items. Items in a tree control are referenced by wxTreeItemId handles.

wxTreeCtrl()
-------------------------

Default constructor.

wxTreeCtrl(wxWindow* parent, wxWindowID id, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxTR_HAS_BUTTONS, const wxValidator& validator = wxDefaultValidator, const wxString& name = "listCtrl")

Constructor, creating and showing a tree control.

Parameters
-------------------

parent = Parent window. Must not be NULL.

id = Window identifier. A value of -1 indicates a default value.

pos = Window position.

size = Window size. If the default size (-1, -1) is specified then the window is sized appropriately.

style = Window style. See wxTreeCtrl.

validator = Window validator.

name = Window name.
