\section{\class{wxDataViewCtrl}}\label{wxdataviewctrl}
-This class and its documentation are work in progress and
-therefore subject to change.

-wxDataViewCtrl is planned to be a control to display data either
-in a tree like fashion or in a tabular form or both. So far,
-only the tabular form is implemented.
+wxDataViewCtrl is a control to display data either
+in a tree like fashion or in a tabular form or both.
Unlike \helpref{wxListCtrl}{wxlistctrl} wxDataViewCtrl doesn't
-get its data from the user through virtual functions or events,
-instead you need to write your own
-\helpref{wxDataViewListModel}{wxdataviewlistmodel} and associate
+get its data from the user through virtual functions or by
+setting it directly. Instead you need to write your own
+\helpref{wxDataViewModel}{wxdataviewmodel} and associate
it with this control. Then you need to add a number of
\helpref{wxDataViewColumn}{wxdataviewcolumn} to this control to
define what each column shall display. Each wxDataViewColumn
Accordingly, all type information uses the strings returned
from \helpref{wxVariant::GetType}{wxvariantgettype}.
-So far, this control has been implemented for GTK+ and there
-is an almost complete generic implementation including several
-additions for a native Windows look and feel (in particular
-concerning the header). It is planned to implement the control
-natively under OS X.

wxDataViewModel is the base class for all data model to be
displayed by a \helpref{wxDataViewCtrl}{wxdataviewctrl}.
-Currently, this class has no functionality at all and the
-only existing implementation of it is the
-\helpref{wxDataViewListModel}{wxdataviewlistmodel}. The
-plan is to move all functionality of wxDataViewListModel
-and a to-be-written wxDataViewTreeModel into wxDataViewModel
-and make wxDataViewListModel and wxDataViewTreeModel subsets
-of the abstract wxDataViewModel.

-wxDataViewListModel is currently the only existing variant
-of a \helpref{wxDataViewModel}{wxdataviewmodel}. It allows
-to define a table like data model to be displayed by a
-\helpref{wxDataViewCtrl}{wxdataviewctrl}. You need to derive
-from this class to define your own data model.
-
-You need to override \helpref{GetRowCount}{wxdataviewlistmodelgetrowcount},
-\helpref{GetColumnCount}{wxdataviewlistmodelgetcolumncount},
-\helpref{GetColumnType}{wxdataviewlistmodelgetcolumntype} and
-\helpref{GetValue}{wxdataviewlistmodelgetvalue} in order to
-define the data model (which acts as an interface between
-your actual data and the wxDataViewCtrl). Since you will
+All other models derive from it and must implement its
+pure virtual functions in order to define a complete
+data model. In detail, you need to override
+\helpref{IsContainer}{wxdataviewmodeliscontainer},
+\helpref{GetParent}{wxdataviewmodelgetparent},
+\helpref{GetColumnCount}{wxdataviewmodelgetcolumncount},
+\helpref{GetColumnType}{wxdataviewmodelgetcolumntype} and
+\helpref{GetValue}{wxdataviewmodelgetvalue} in order to
+define the data model which acts as an interface between
+your actual data and the wxDataViewCtrl. Since you will
usually also allow the wxDataViewCtrl to change your data
through its graphical interface, you will also have to override
\helpref{SetValue}{wxdataviewlistmodelsetvalue} which the
wxDataViewCtrl will call when a change to some data has been
commited.
-The data that is presented through this data model is expected
-to change at run-time. You need to inform the data model that
-a change happens. Depending on what happened you need to call
-one of the following methods:
-\helpref{ValueChanged}{wxdataviewlistmodelvaluechanged},
-\helpref{RowChanged}{wxdataviewlistmodelrowchanged},
-\helpref{RowAppended}{wxdataviewlistmodelrowappended},
-\helpref{RowPrepended}{wxdataviewlistmodelrowprepended},
-\helpref{RowInserted}{wxdataviewlistmodelrowinserted},
-\helpref{RowDeleted}{wxdataviewlistmodelrowdeleted},
-\helpref{RowsReordered}{wxdataviewlistmodelrowsreordered} or
-\helpref{RowsCleared}{wxdataviewlistmodelcleared}.

-wxDataViewModel and this class (as indeed the entire wxDataViewCtrl
+wxDataViewModel (as indeed the entire wxDataViewCtrl
code) is using \helpref{wxVariant}{wxvariant} to store data and
its type in a generic way. wxVariant can be extended to contain
almost any data without changes to the original class.
+The data that is presented through this data model is expected
+to change at run-time. You need to inform the data model when
+a change happened. Depending on what happened you need to call
+one of the following methods:
+\helpref{ValueChanged}{wxdataviewmodelvaluechanged},
+\helpref{ItemAdded}{wxdataviewmodelitemadded},
+\helpref{ItemDeleted}{wxdataviewmodelitemdeleted},
+\helpref{ItemChanged}{wxdataviewmodelitemchanged},
+\helpref{Cleared}{wxdataviewmodelcleared}.
+
+Note that wxDataViewModel does not define the position or
+index of any item in the control since several control might
+display the data differently, but wxDataViewModel does
+provide a \helpref{Compare}{wxdataviewmodelcompare} method
+which the wxDataViewCtrl may use to sort the data.
+
This class maintains a list of
-\helpref{wxDataListViewListModelNotifier}{wxdataviewlistmodelnotifier}
+\helpref{wxDataViewModelNotifier}{wxdataviewmodelnotifier}
which link this class to the specific implementations on the
supported platforms so that e.g. calling
-\helpref{ValueChanged}{wxdataviewlistmodelvaluechanged}
+\helpref{ValueChanged}{wxdataviewmodelvaluechanged}
on this model will just call
-\helpref{wxDataListViewListModelNotifier::ValueChanged}{wxdataviewlistmodelnotifiervaluechanged}
-for each notifier that has been added. This is used both for
-informing the native controls to redraw themselves and for informing
-e.g. the \helpref{wxDataViewSortedListModel}{wxdataviewsortedlistmodel}
-to resort itself. You can also add your own notifier in order
-to get informed about any changes to the data in the list model.
-
-Additionally, this class maintains a list of all
-\helpref{wxDataViewColumns}{wxdataviewcolumn} which
-display a certain column of this list model. This is
-mostly used internally.
+\helpref{wxDataViewModelNotifier::ValueChanged}{wxdataviewmodelnotifiervaluechanged}
+for each notifier that has been added. You can also add
+your own notifier in order to get informed about any changes
+to the data in the list model.
+
+Currently wxWidgets provides the following models apart
+from the base model:
+\helpref{wxDataViewIndexListModel}{wxdataviewindexlistmodel}.
+It is planned to add helper classes for simple tree
+and list stores in the future.

-\func{}{\destruct{wxDataViewSortedListModel}}{\void}

-\func{bool}{GetAscending}{\void}
+\func{void}{Resort}{\void}
-Returns true if the data is sorted in ascending order.
+Call this to initiate a resort after the sort function has
+been changed.

-\func{void}{Resort}{\void}
+\func{bool}{SetValue}{\param{const wxVariant\& }{variant}, \param{const wxDataViewItem\& }{item}, \param{unsigned int }{col}}
-Tell the model to resort its data.
+This gets called in order to set a value in the data model.
+The most common scenario is that the wxDataViewCtrl calls
+this method after the user changed some data in the view.
+Afterwards \helpref{ValueChanged}{wxdataviewmodelvaluechanged}
+has to be called!
-\membersection{wxDataViewSortedListModel::SetAscending}\label{wxdataviewsortedlistmodelsetascending}

-\func{void}{SetAscending}{\param{bool }{ascending}}
+\func{bool}{ValueChanged}{\param{const wxDataViewItem\& }{item}, \param{unsigned int }{col}}
-Set the sort order of the data.
+Call this to inform this model that a value in
+the model has been changed.
