 128 /**
 129     @class wxDataViewModel
 130
 131     wxDataViewModel is the base class for all data model to be displayed by a
 132     wxDataViewCtrl.
 133
 134     All other models derive from it and must implement its pure virtual functions
 135     in order to define a complete data model. In detail, you need to override
 136     wxDataViewModel::IsContainer, wxDataViewModel::GetParent, wxDataViewModel::GetChildren,
 137     wxDataViewModel::GetColumnCount, wxDataViewModel::GetColumnType and
 138     wxDataViewModel::GetValue in order to define the data model which acts as an
 139     interface between your actual data and the wxDataViewCtrl.
 140
 141     Since you will usually also allow the wxDataViewCtrl to change your data
 142     through its graphical interface, you will also have to override
 143     wxDataViewModel::SetValue which the wxDataViewCtrl will call when a change
 144     to some data has been commited.
 145
 146     wxDataViewModel (as indeed the entire wxDataViewCtrl code) is using wxVariant
 147     to store data and its type in a generic way. wxVariant can be extended to contain
 148     almost any data without changes to the original class.
 149
 150     The data that is presented through this data model is expected to change at
 151     run-time. You need to inform the data model when a change happened.
 152     Depending on what happened you need to call one of the following methods:
 153     - wxDataViewModel::ValueChanged,
 154     - wxDataViewModel::ItemAdded,
 155     - wxDataViewModel::ItemDeleted,
 156     - wxDataViewModel::ItemChanged,
 157     - wxDataViewModel::Cleared.
 158
 159     There are plural forms for notification of addition, change or removal of
 160     several item at once. See:
 161     - wxDataViewModel::ItemsAdded,
 162     - wxDataViewModel::ItemsDeleted,
 163     - wxDataViewModel::ItemsChanged.
 164
 165     Note that wxDataViewModel does not define the position or index of any item
 166     in the control because different controls might display the same data differently.
 167     wxDataViewModel does provide a wxDataViewModel::Compare method which the
 168     wxDataViewCtrl may use to sort the data either in conjunction with a column
 169     header or without (see wxDataViewModel::HasDefaultCompare).
 170
 171     This class maintains a list of wxDataViewModelNotifier which link this class
 172     to the specific implementations on the supported platforms so that e.g. calling
 173     wxDataViewModel::ValueChanged on this model will just call
 174     wxDataViewModelNotifier::ValueChanged for each notifier that has been added.
 175     You can also add your own notifier in order to get informed about any changes
 176     to the data in the list model.
 177
 178     Currently wxWidgets provides the following models apart from the base model:
 179     wxDataViewIndexListModel, wxDataViewVirtualListModel, wxDataViewTreeStore.
 180
 181     Note that wxDataViewModel is reference counted, derives from wxObjectRefData
 182     and cannot be deleted directly as it can be shared by several wxDataViewCtrls.
 183     This implies that you need to decrease the reference count after
 184     associating the model with a control like this:
 185
 186     @code
 187         wxDataViewCtrl *musicCtrl = new wxDataViewCtrl( this, ID_MUSIC_CTRL );
 188         wxDataViewModel *musicModel = new MyMusicModel;
 189         m_musicCtrl-AssociateModel( musicModel );
 190         musicModel-DecRef();  // avoid memory leak !!
 191         // add columns now
 192     @endcode

 493     @class wxDataViewVirtualListModel
 494
 495     wxDataViewVirtualListModel is a specialized data model which lets you address
 496     an item by its position (row) rather than its wxDataViewItem and as such offers
 497     the exact same interface as wxDataViewIndexListModel.
 498     The important difference is that under platforms other than OS X, using this
 499     model will result in a truly virtual control able to handle millions of items
 500     as the control doesn't store any item (a feature not supported by the
 501     Carbon API under OS X).
 502
 503     @see wxDataViewIndexListModel for the API.

 601     @class wxDataViewCtrl
 602
 603     wxDataViewCtrl is a control to display data either in a tree like fashion or
 604     in a tabular form or both.
 605     If you only need to display a simple tree structure with an API more like the
 606     older wxTreeCtrl class, then the specialized wxDataViewTreeCtrl can be used.
 607
 608     A wxDataViewItem is used to represent a (visible) item in the control.
 609
 610     Unlike wxListCtrl wxDataViewCtrl doesn't get its data from the user through
 611     virtual functions or by setting it directly. Instead you need to write your own
 612     wxDataViewModel and associate it with this control.
 613     Then you need to add a number of wxDataViewColumn to this control to define
 614     what each column shall display. Each wxDataViewColumn in turn owns 1 instance
 615     of a wxDataViewRenderer to render its cells.
 616
 617     A number of standard renderers for rendering text, dates, images, toggle,
 618     a progress bar etc. are provided. Additionally, the user can write custom
 619     renderes deriving from wxDataViewCustomRenderer for displaying anything.
 620
 621     All data transfer from the control to the model and the user code is done
 622     through wxVariant which can be extended to support more data formats as necessary.
 623     Accordingly, all type information uses the strings returned from wxVariant::GetType.
 624
 625     @beginStyleTable
 626     @style{wxDV_SINGLE}
 627            Single selection mode. This is the default.
 628     @style{wxDV_MULTIPLE}
 629            Multiple selection mode.
 630     @style{wxDV_ROW_LINES}
 631            Use alternating colours for rows if supported by platform and theme.
 632     @style{wxDV_HORIZ_RULES}
 633            Display fine rules between row if supported.
 634     @style{wxDV_VERT_RULES}
 635            Display fine rules between columns is supported.
 636     @style{wxDV_VARIABLE_LINE_HEIGHT}
 637            Allow variable line heights.
 638             This can be inefficient when displaying large number of items.

1779     wxDataViewTreeStore is a specialised wxDataViewModel for displaying simple
1780     trees very much like wxTreeCtrl does and it offers a similar API.
1781
1782     This class actually stores the entire tree (therefore its name) and implements
1783     all virtual methods from the base class so it can be used directly without
1784     having to derive any class from it.
1785     This comes at the price of much reduced flexibility.
