+directly as it can be shared by several wxDataViewCtrls. This
implies that you need to decrease the reference count after
associating the model with a control like this:
\latexignore{\rtfignore{\wxheading{Members}}}
+
\membersection{wxDataViewModel::wxDataViewModel}\label{wxdataviewmodelwxdataviewmodel}
\func{}{wxDataViewModel}{\void}
Constructor.

+
+\func{bool}{GetAttr}{\param{const wxDataViewItem\& }{item}, \param{unsigned int }{col}, \param{wxDataViewItemAttr\& }{attr}}

+
\membersection{wxDataViewModel::GetColumnCount}\label{wxdataviewmodelgetcolumncount}
\constfunc{virtual unsigned int}{GetColumnCount}{\void}
Override this to indicate the number of columns in the model.
+
\membersection{wxDataViewModel::GetColumnType}\label{wxdataviewmodelgetcolumntype}
\constfunc{virtual wxString}{GetColumnType}{\param{unsigned int }{col}}
column specified by {\it col}. This should return a string
indicating the type of data as reported by \helpref{wxVariant}{wxvariant}.
+
\membersection{wxDataViewModel::GetChildren}\label{wxdataviewmodelgetchildren}
\constfunc{virtual unsigned int}{GetChildren}{\param{const wxDataViewItem\& }{item}, \param{wxDataViewItemArray\& }{children} }
Override this so the control can query the child items of
an item. Returns the number of items.
+
\membersection{wxDataViewModel::GetParent}\label{wxdataviewmodelgetparent}
\constfunc{virtual wxDataViewItem}{GetParent}{\param{const wxDataViewItem\& }{item}}
of {\it item} or an invalid wxDataViewItem if the the root item is
the parent item.

\membersection{wxDataViewModel::GetValue}\label{wxdataviewmodelgetvalue}
\constfunc{virtual void}{GetValue}{\param{wxVariant\& }{variant}, \param{const wxDataViewItem\& }{item}, \param{unsigned int }{col}}
A \helpref{wxVariant}{wxvariant} is used to store the data.
+
\membersection{wxDataViewModel::HasContainerColumns}\label{wxdataviewmodelhascontainercolumns}
\constfunc{virtual bool}{HasContainerColumns}{\param{const wxDataViewItem\& }{item}}
acts a normal item with entries for futher columns. By
default returns {\it false}.
+
\membersection{wxDataViewModel::HasDefaultCompare}\label{wxdataviewmodelhasdefaultcompare}
\constfunc{virtual bool}{HasDefaultCompare}{\void}
should be used. See also \helpref{wxDataViewIndexListModel}{wxdataviewindexlistmodel}
for a model which makes use of this.
+
\membersection{wxDataViewModel::IsContainer}\label{wxdataviewmodeliscontainer}
\constfunc{virtual bool}{IsContainer}{\param{const wxDataViewItem\& }{item}}

to the data.
+
\membersection{wxDataViewModel::ItemChanged}\label{wxdataviewmodelitemchanged}
\func{virtual bool}{ItemChanged}{\param{const wxDataViewItem\& }{item}}
This will eventually emit a wxEVT\_DATAVIEW\_ITEM\_VALUE\_CHANGED
event (in which the column fields will not be set) to the user.
+
+\membersection{wxDataViewModel::ItemDeleted}\label{wxdataviewmodelitemdeleted}
+
+\func{virtual bool}{ItemDeleted}{\param{const wxDataViewItem\& }{parent}, \param{const wxDataViewItem\& }{item}}

+
\membersection{wxDataViewModel::ItemsAdded}\label{wxdataviewmodelitemsadded}
\func{virtual bool}{ItemsAdded}{\param{const wxDataViewItem\& }{parent}, \param{const wxDataViewItemArray\& }{items}}

to the data.
+
\membersection{wxDataViewModel::ItemsChanged}\label{wxdataviewmodelitemschanged}
\func{virtual bool}{ItemsChanged}{\param{const wxDataViewItemArray\& }{items}}
This will eventually emit wxEVT\_DATAVIEW\_ITEM\_VALUE\_CHANGED
events (in which the column fields will not be set) to the user.
+
\membersection{wxDataViewModel::ItemsDeleted}\label{wxdataviewmodelitemsdeleted}
\func{virtual bool}{ItemsDeleted}{\param{const wxDataViewItem\& }{parent}, \param{const wxDataViewItemArray\& }{items}}
