   3
   4 wxDataViewCtrl is a control to display data either
   5 in a tree like fashion or in a tabular form or both.
   6
   7 A \helpref{wxDataViewItem}{wxdataviewitem} is used
   8 to represent a (visible) item in the control.
   9
  10 Unlike \helpref{wxListCtrl}{wxlistctrl} wxDataViewCtrl doesn't
  11 get its data from the user through virtual functions or by
  12 setting it directly. Instead you need to write your own
  13 \helpref{wxDataViewModel}{wxdataviewmodel} and associate
  14 it with this control. Then you need to add a number of
  15 \helpref{wxDataViewColumn}{wxdataviewcolumn} to this control to
  16 define what each column shall display. Each wxDataViewColumn
  17 in turn owns 1 instance of a
  18 \helpref{wxDataViewRenderer}{wxdataviewrenderer} to render its
  19 cells. A number of standard renderers for rendering text, dates,
  20 images, toggle, a progress bar etc. are provided. Additionally,
  21 the user can write custom renderes deriving from
  22 \helpref{wxDataViewCustomRenderer}{wxdataviewcustomrenderer}
  23 for displaying anything.
  24
  25 All data transfer from the control to the model and the user
  26 code is done through \helpref{wxVariant}{wxvariant} which can
  27 be extended to support more data formats as necessary.
  28 Accordingly, all type information uses the strings returned
  29 from \helpref{wxVariant::GetType}{wxvariantgettype}.

  42 To process input from a dataview control, use the following event handler
  43 macros to direct input to member functions that take a
  44 \helpref{wxDataViewEvent}{wxdataviewevent} argument.
