From 4c192bc802b0a35ecbbec5e80011093e874972e4 Mon Sep 17 00:00:00 2001 From: Gabriel Jacobo Date: Tue, 25 Feb 2014 17:42:34 -0300 Subject: [PATCH] Fixes #2308, recreate window if GL requirements for the renderer are not met If the window has been created with values for SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_MAJOR_VERSION and SDL_GL_CONTEXT_MINOR_VERSION not matching those required by the renderer, attempt to recreate the window. This is needed on platforms where both GL and GLES 1/2 surfaces are supported by the video backend, requiring that the window be recreated when switching between context types. --- src/render/opengl/SDL_render_gl.c | 17 ++++++++++++++++- src/render/opengles/SDL_render_gles.c | 23 +++++++++++++---------- src/render/opengles2/SDL_render_gles2.c | 23 +++++++++++++---------- 3 files changed, 42 insertions(+), 21 deletions(-) diff --git a/src/render/opengl/SDL_render_gl.c b/src/render/opengl/SDL_render_gl.c index 178927686..5a51b4644 100644 --- a/src/render/opengl/SDL_render_gl.c +++ b/src/render/opengl/SDL_render_gl.c @@ -32,6 +32,8 @@ #include #endif +#define RENDERER_CONTEXT_MAJOR 2 +#define RENDERER_CONTEXT_MINOR 0 /* OpenGL renderer implementation */ @@ -381,11 +383,24 @@ GL_CreateRenderer(SDL_Window * window, Uint32 flags) const char *hint;
