@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

+ interface between your actual data and the wxDataViewCtrl.
+
+ 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).
+
+ 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. To a certain extent,
+ you can use (the somewhat more elegant) wxAny instead of wxVariant as there
+ is code to convert between the two, but it is unclear what impact this will
+ have on performance.
+
+ Since you will usually 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.

- 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,

-
- Note that wxDataViewModel does not define the position or

- might display the same data differently. wxDataViewModel does
- provide a wxDataViewModel::Compare method

- on this model will just call

- for each notifier that has been added. You can also add
- your own notifier in order to get informed about any changes
+ wxDataViewModel::SetValue which the wxDataViewCtrl will call when a change
+ to some data has been committed.
+
+ If the data represented by the model is changed by something else than its
+ associated wxDataViewCtrl, the control has to be notified about the change.

/**
@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.
