wxWidgets/wxPython/demo/wxTreeCtrl.py
Robin Dunn 96bfd05319 Images can now be embedded in Python source files.
Added tools to do the embedding.
Added Constructors/methods where needed.
Updated the demo to use mostly embedded images.

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.
