 131     @wxheader{dataview.h}
 132
 133     wxDataViewModel is the base class for all data model to be
 134     displayed by a wxDataViewCtrl.
 135     All other models derive from it and must implement its
 136     pure virtual functions in order to define a complete
 137     data model. In detail, you need to override
 138     wxDataViewModel::IsContainer,
 139     wxDataViewModel::GetParent,
 140     wxDataViewModel::GetChildren,
 141     wxDataViewModel::GetColumnCount,
 142     wxDataViewModel::GetColumnType and
 143     wxDataViewModel::GetValue in order to
 144     define the data model which acts as an interface between
 145     your actual data and the wxDataViewCtrl. Since you will
 146     usually also allow the wxDataViewCtrl to change your data
 147     through its graphical interface, you will also have to override
 148     wxDataViewModel::SetValue which the
 149     wxDataViewCtrl will call when a change to some data has been
 150     commited.
 151
 152     wxDataViewModel (as indeed the entire wxDataViewCtrl
 153     code) is using wxVariant to store data and
 154     its type in a generic way. wxVariant can be extended to contain
 155     almost any data without changes to the original class.
 156
 157     The data that is presented through this data model is expected
 158     to change at run-time. You need to inform the data model when
 159     a change happened. Depending on what happened you need to call
 160     one of the following methods:
 161     wxDataViewModel::ValueChanged,
 162     wxDataViewModel::ItemAdded,
 163     wxDataViewModel::ItemDeleted,
 164     wxDataViewModel::ItemChanged,
 165     wxDataViewModel::Cleared. There are
 166     plural forms for notification of addition, change
 167     or removal of several item at once. See
 168     wxDataViewModel::ItemsAdded,
 169     wxDataViewModel::ItemsDeleted,
 170     wxDataViewModel::ItemsChanged.
 171
 172     Note that wxDataViewModel does not define the position or
 173     index of any item in the control because different controls
 174     might display the same data differently. wxDataViewModel does
 175     provide a wxDataViewModel::Compare method
 176     which the wxDataViewCtrl may use to sort the data either
 177     in conjunction with a column header or without (see
 178     wxDataViewModel::HasDefaultCompare).
 179
 180     This class maintains a list of
 181     wxDataViewModelNotifier
 182     which link this class to the specific implementations on the
 183     supported platforms so that e.g. calling
 184     wxDataViewModel::ValueChanged
 185     on this model will just call
 186     wxDataViewModelNotifier::ValueChanged
 187     for each notifier that has been added. You can also add
 188     your own notifier in order to get informed about any changes
 189     to the data in the list model.
 190
 191     Currently wxWidgets provides the following models apart
 192     from the base model:
 193     wxDataViewIndexListModel,
 194     wxDataViewVirtualListModel,
 195     wxDataViewTreeStore.
 196
 197     Note that wxDataViewModel is reference counted, derives from
 198     wxObjectRefData and cannot be deleted
 199     directly as it can be shared by several wxDataViewCtrls. This
 200     implies that you need to decrease the reference count after
 201     associating the model with a control like this:
 202
 203     @code
 204     wxDataViewCtrl *musicCtrl = new wxDataViewCtrl( this, ID_MUSIC_CTRL );
 205         wxDataViewModel *musicModel = new MyMusicModel;
 206         m_musicCtrl-AssociateModel( musicModel );
 207         musicModel-DecRef();  // avoid memory leak !!
 208         // add columns now
 209     @endcode

 524     Carbon API under OS X).

 636
 637     wxDataViewCtrl is a control to display data either
 638     in a tree like fashion or in a tabular form or both.
 639     If you only need to display a simple tree structure
 640     with an API more like the older wxTreeCtrl class,
 641     then the specialized wxDataViewTreeCtrl
 642     can be used.
 643
 644     A wxDataViewItem is used
 645     to represent a (visible) item in the control.
 646
 647     Unlike wxListCtrl wxDataViewCtrl doesn't
 648     get its data from the user through virtual functions or by
 649     setting it directly. Instead you need to write your own
 650     wxDataViewModel and associate
 651     it with this control. Then you need to add a number of
 652     wxDataViewColumn to this control to
 653     define what each column shall display. Each wxDataViewColumn
 654     in turn owns 1 instance of a
 655     wxDataViewRenderer to render its
 656     cells. A number of standard renderers for rendering text, dates,
 657     images, toggle, a progress bar etc. are provided. Additionally,
 658     the user can write custom renderes deriving from
 659     wxDataViewCustomRenderer
 660     for displaying anything.
 661
 662     All data transfer from the control to the model and the user
 663     code is done through wxVariant which can
 664     be extended to support more data formats as necessary.
 665     Accordingly, all type information uses the strings returned
 666     from wxVariant::GetType.

 669     @style{wxDV_SINGLE}

1088     One instance of a renderer class is owned by a wxDataViewColumn. There
1089     is a number of ready-to-use renderers provided:
1090     wxDataViewTextRenderer,

1096     wxDataViewDateRenderer.
1097     wxDataViewSpinRenderer.
1098
1099     Additionally, the user can write own renderers by deriving from
1100     wxDataViewCustomRenderer.
1101
1102     The @e wxDataViewCellMode flag controls, what actions
1103     the cell data allows. @e wxDATAVIEW_CELL_ACTIVATABLE
1104     indicates that the user can double click the cell and
1105     something will happen (e.g. a window for editing a date
1106     will pop up). @e wxDATAVIEW_CELL_EDITABLE indicates
1107     that the user can edit the data in-place, i.e. an control
1108     will show up after a slow click on the cell. This behaviour
1109     is best known from changing the filename in most file
1110     managers etc.
1111

1846     wxDataViewTreeStore is a specialised wxDataViewModel
1847     for displaying simple trees very much like wxTreeCtrl
1848     does and it offers a similar API. This class actually stores the entire
1849     tree (therefore its name) and implements all virtual methods from the base
1850     class so it can be used directly without having to derive any class from it.
1851     This comes at the price of much reduced flexibility.
