  13
  14 This simple struct represents the \helpref{wxRendererNative}{wxrenderernative}
  15 interface version and is only used as the return value of
  16 \helpref{wxRendererNative::GetVersion}{wxrenderernativegetversion}.
  17
  18 The version has two components: the version itself and the age. If the main
  19 program and the renderer have different versions they are never compatible with
  20 each other because the version is only changed when an existing virtual
  21 function is modified or removed. The age, on the other hand, is incremented
  22 each time a new virtual method is added and so, at least for the compilers
  23 using a common C++ object model, the calling program is compatible with any
  24 renderer which has the age greater or equal to its age. This verification is
  25 done by \helpref{IsCompatible}{wxrenderernativeiscompatible} method.

  41 \func{static bool}{IsCompatible}{\param{const wxRendererVersion\& }{ver}}
  42
  43 Checks if the main program is compatible with the renderer having the version
  44 \arg{ver}, returns \true if it is and \false otherwise.
  45
  46 This method is used by
  47 \helpref{wxRendererNative::Load}{wxrenderernativeload} to determine whether a
  48 renderer can be used.
