==========================================================================================================================================
|phoenix_title|  **wx.dataview.DataViewTreeCtrl**
==========================================================================================================================================

This class is a :ref:`wx.dataview.DataViewCtrl`  which internally uses a :ref:`wx.dataview.DataViewTreeStore`  and forwards most of its API to that class.          

Additionally, it uses a :ref:`wx.ImageList`  to store a list of icons. 

The main purpose of this class is to provide a simple upgrade path for code using :ref:`wx.TreeCtrl`. 

^^ 



.. _DataViewTreeCtrl-styles:

================================

This class supports the following styles: 

  See :ref:`wx.dataview.DataViewCtrl`  for the list of supported styles. ^^

.. _DataViewTreeCtrl-events:

|events| Events Emitted by this Class
=====================================

Event macros for events emitted by this class: 

  See :ref:`wx.dataview.DataViewCtrl`  for the list of events emitted by this class. ^^
