Class VCL_DLLPUBLIC SalGraphics
Implementation
The class SalGraphics is an empty box (technically an abstract class with pure virtual methods) which is used to create a specific class in accordance with the OS used. salgdi.hxx is included in salgdi.h existing for every single OS and which are included itself into salgdi.cxx existing for every single OS too.
This class is the an abstract data type which can not be instantiated. It is completed for each OS in following files:
Windows
- Inherited class : WinSalGraphics
- /vcl/win/inc/salgdi.h
