3 | ||
4 | This class and its documentation are work in progress and | |
305c49a1 | 5 | therefore subject to change. |

7 | wxDataViewCtrl is planned to be a control to display data either | |
305c49a1 RR |
8 | in a tree like fashion or in a tabular form or both. So far, |
9 | only the tabular form is implemented. | |
10 | ||
11 | Unlike \helpref{wxListCtrl}{wxlistctrl} wxDataViewCtrl doesn't | |
b6b9d556 RR |
12 | get its data from the user through virtual functions or events, |
13 | instead you need to write your own | |
14 | \helpref{wxDataViewListModel}{wxdataviewlistmodel} and associate | |
15 | it with this control. Then you need to add a number of | |
16 | \helpref{wxDataViewColumn}{wxdataviewcolumn} to this control to | |
17 | define what each column shall display. Each wxDataViewColumn | |
18 | in turn owns 1 instance of a | |
19 | \helpref{wxDataViewRenderer}{wxdataviewrenderer} to render its | |
20 | cells. A number of standard renderers for rendering text, dates, | |
21 | images, toggle, a progress bar etc. are provided. Additionally, | |
22 | the user can write custom renderes deriving from | |
23 | \helpref{wxDataViewCustomRenderer}{wxdataviewcustomrenderer} | |
24 | for displaying anything. | |
25 | ||
26 | All data transfer from the control to the model and the user | |
27 | code is done through \helpref{wxVariant}{wxvariant} which can | |
28 | be extended to support more data formats as necessary. | |
29 | Accordingly, all type information uses the strings returned | |
30 | from \helpref{wxVariant::GetType}{wxvariantgettype}. | |
31 | ||
305c49a1 RR |
32 | So far, this control has been implemented for GTK+ and there |
33 | is an almost complete generic implementation including several | |
34 | additions for a native Windows look and feel (in particular | |
35 | concerning the header). It is planned to implement the control | |
36 | natively under OS X. | |

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

7ffc857f | 64 | \helpref{model}{wxdataviewlistmodel}, to which a wxDataViewCtrl |
1821abd1 RR |
65 | has been associated. These events correspond to the interface |
66 | offered by \helpref{wxDataViewListModelNotifier}{wxdataviewlistmodelnotifier}. | |
