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

\func{static bool}{IsCompatible}{\param{const wxRendererVersion\& }{ver}}
|
|
|
|
|
|
|
|
|
|
Checks if the main program is compatible with the renderer having the version
|
|
|
|
|
\arg{ver}, returns \true if it is and \false otherwise.

This method is used by
|
|
|
|
|
\helpref{wxRendererNative::Load}{wxrenderernativeload} to determine whether a
|
|
|
|
|
renderer can be used.
