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}.

41
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.
