/**
@class wxDataViewModel
wxDataViewModel is the base class for all data model to be displayed by a
wxDataViewCtrl.
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
wxDataViewModel::IsContainer, wxDataViewModel::GetParent, wxDataViewModel::GetChildren,
wxDataViewModel::GetColumnCount, wxDataViewModel::GetColumnType and
wxDataViewModel::GetValue 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
wxDataViewModel::SetValue which the wxDataViewCtrl will call when a change
to some data has been commited.
wxDataViewModel (as indeed the entire wxDataViewCtrl code) is using 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:
- wxDataViewModel::ValueChanged,
- wxDataViewModel::ItemAdded,
- wxDataViewModel::ItemDeleted,
- wxDataViewModel::ItemChanged,
- wxDataViewModel::Cleared.
There are plural forms for notification of addition, change or removal of
several item at once. See:
- wxDataViewModel::ItemsAdded,
- wxDataViewModel::ItemsDeleted,
- wxDataViewModel::ItemsChanged.
Note that wxDataViewModel does not define the position or index of any item
in the control because different controls might display the same data differently.
wxDataViewModel does provide a wxDataViewModel::Compare method which the
wxDataViewCtrl may use to sort the data either in conjunction with a column
header or without (see wxDataViewModel::HasDefaultCompare).
This class maintains a list of wxDataViewModelNotifier which link this class
to the specific implementations on the supported platforms so that e.g. calling
wxDataViewModel::ValueChanged on this model will just call
wxDataViewModelNotifier::ValueChanged 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:
wxDataViewIndexListModel, wxDataViewVirtualListModel, wxDataViewTreeStore.
Note that wxDataViewModel is reference counted, derives from wxObjectRefData
and cannot be deleted 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:
@code
wxDataViewCtrl *musicCtrl = new wxDataViewCtrl( this, ID_MUSIC_CTRL );
wxDataViewModel *musicModel = new MyMusicModel;
m_musicCtrl-AssociateModel( musicModel );
musicModel-DecRef(); // avoid memory leak !!
// add columns now
@endcode

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