Date: Thu, 19 Jan 2006 20:02:29 +0200 From: Vassilis Virvilis <vasvir@iit.demokritos.gr> Subject: [SDL] Request: Please reconsider adding tag in SDL_Event Hi, Patch in question: --- include/SDL_events.h 20 Aug 2004 18:57:01 -0000 1.11 +++ include/SDL_events.h 19 Jan 2006 17:35:09 -0000 @@ -214,7 +214,7 @@ } SDL_SysWMEvent; /* General event structure */ -typedef union { +typedef union SDL_Event { Uint8 type; SDL_ActiveEvent active; SDL_KeyboardEvent key; Reasoning: ---------- 1) Allows forward declaration of the SDL_Event union in C++. Please note that in plain C it is possible to forward declare it. 2) Forward declaration is good because it allows encapsulation. It hides the specific implementation and does not necessarily exposes SDL staff to my appication's namespace 3) It can't harm plain C because tags are living in a different namespace than typenames 4) It is already done like this in other places in SDL. Check for example SDL_KeySym, and SDL_.*Event structures. 5) Right now I have to include SDL/event.h from a C++ header file. See 2)
