  11     @class wxDataViewModel
  12
  13     wxDataViewModel is the base class for all data model to be displayed by a
  14     wxDataViewCtrl.
  15
  16     All other models derive from it and must implement its pure virtual functions
  17     in order to define a complete data model. In detail, you need to override
  18     wxDataViewModel::IsContainer, wxDataViewModel::GetParent, wxDataViewModel::GetChildren,
  19     wxDataViewModel::GetColumnCount, wxDataViewModel::GetColumnType and
  20     wxDataViewModel::GetValue in order to define the data model which acts as an
  21     interface between your actual data and the wxDataViewCtrl.
  22
  23     Since you will usually also allow the wxDataViewCtrl to change your data
  24     through its graphical interface, you will also have to override
  25     wxDataViewModel::SetValue which the wxDataViewCtrl will call when a change
  26     to some data has been commited.
  27
  28     wxDataViewModel (as indeed the entire wxDataViewCtrl code) is using wxVariant
  29     to store data and its type in a generic way. wxVariant can be extended to contain
  30     almost any data without changes to the original class.
  31
  32     The data that is presented through this data model is expected to change at
  33     run-time. You need to inform the data model when a change happened.
  34     Depending on what happened you need to call one of the following methods:
  35     - wxDataViewModel::ValueChanged,
  36     - wxDataViewModel::ItemAdded,
  37     - wxDataViewModel::ItemDeleted,
  38     - wxDataViewModel::ItemChanged,
  39     - wxDataViewModel::Cleared.
  40
  41     There are plural forms for notification of addition, change or removal of
  42     several item at once. See:
  43     - wxDataViewModel::ItemsAdded,
  44     - wxDataViewModel::ItemsDeleted,
  45     - wxDataViewModel::ItemsChanged.
  46
  47     Note that wxDataViewModel does not define the position or index of any item
  48     in the control because different controls might display the same data differently.
  49     wxDataViewModel does provide a wxDataViewModel::Compare method which the
  50     wxDataViewCtrl may use to sort the data either in conjunction with a column
  51     header or without (see wxDataViewModel::HasDefaultCompare).
  52
  53     This class maintains a list of wxDataViewModelNotifier which link this class
  54     to the specific implementations on the supported platforms so that e.g. calling
  55     wxDataViewModel::ValueChanged on this model will just call
  56     wxDataViewModelNotifier::ValueChanged for each notifier that has been added.
  57     You can also add your own notifier in order to get informed about any changes
  58     to the data in the list model.
  59
  60     Currently wxWidgets provides the following models apart from the base model:
  61     wxDataViewIndexListModel, wxDataViewVirtualListModel, wxDataViewTreeStore,
  62     wxDataViewListStore.
  63
  64     Note that wxDataViewModel is reference counted, derives from wxObjectRefData
  65     and cannot be deleted directly as it can be shared by several wxDataViewCtrls.
  66     This implies that you need to decrease the reference count after
  67     associating the model with a control like this:
  68
  69     @code
  70         wxDataViewCtrl *musicCtrl = new wxDataViewCtrl( this, ID_MUSIC_CTRL );
  71         wxDataViewModel *musicModel = new MyMusicModel;
  72         m_musicCtrl-AssociateModel( musicModel );
  73         musicModel-DecRef();  // avoid memory leak !!
  74         // add columns now
  75     @endcode

 490     older wxTreeCtrl class, then the specialized wxDataViewTreeCtrl can be used.
 491     Likewise, if you only want to display simple table structure you can use
 492     the specialized wxDataViewListCtrl class. Both wxDataViewTreeCtrl and
 493     wxDataViewListCtrl can be used without defining  your own wxDataViewModel.
 494
 495     A wxDataViewItem is used to represent a (visible) item in the control.
 496
 497     Unlike wxListCtrl, wxDataViewCtrl doesn't get its data from the user through
 498     virtual functions or by setting it directly. Instead you need to write your own
 499     wxDataViewModel and associate it with this control.
 500     Then you need to add a number of wxDataViewColumn to this control to define
 501     what each column shall display. Each wxDataViewColumn in turn owns 1 instance
 502     of a wxDataViewRenderer to render its cells.
 503
 504     A number of standard renderers for rendering text, dates, images, toggle,
 505     a progress bar etc. are provided. Additionally, the user can write custom
 506     renderers deriving from wxDataViewCustomRenderer for displaying anything.
 507
 508     All data transfer from the control to the model and the user code is done
 509     through wxVariant which can be extended to support more data formats as necessary.
 510     Accordingly, all type information uses the strings returned from wxVariant::GetType.

 512     @beginStyleTable
 513     @style{wxDV_SINGLE}
 514            Single selection mode. This is the default.
 515     @style{wxDV_MULTIPLE}
 516            Multiple selection mode.
 517     @style{wxDV_ROW_LINES}
 518            Use alternating colours for rows if supported by platform and theme.
 519     @style{wxDV_HORIZ_RULES}
 520            Display fine rules between row if supported.
 521     @style{wxDV_VERT_RULES}
 522            Display fine rules between columns is supported.
 523     @style{wxDV_VARIABLE_LINE_HEIGHT}
 524            Allow variable line heights.
 525             This can be inefficient when displaying large number of items.
