/*
|
||
|
Note about the structure of various headers: they're organized in a more
|
||
|
complicated way than usual because of the various dependencies which are
|
||
|
different for different ports. In any case the only public header, i.e. the
|
||
|
one which can be included directly is wx/dataview.h. It, in turn, includes
|
||
|
this one to define all the renderer classes.
|
||
|
|
||
|
We define the base wxDataViewRendererBase class first and then include a
|
||
|
port-dependent wx/xxx/dvrenderer.h which defines wxDataViewRenderer itself.
|
||
|
After this we can define wxDataViewRendererCustomBase (and maybe in the
|
||
|
future base classes for other renderers if the need arises, i.e. if there
|
||
|
is any non-trivial code or API which it makes sense to keep in common code)
|
||
|
and include wx/xxx/dvrenderers.h (notice the plural) which defines all the
|
||
|
rest of the renderer classes.
