But also: "Could not make GL context current" is not a string that appears in SDL's source code...is Qtalsotrying to make a GL context on this window, and this is causing a conflict with SDL, causing it to write out thoseDEBUGlines?
* EGL can now create/manage OpenGL and OpenGL ES 1.x/2.x contexts, and share them using SDL_GL_SHARE_WITH_CURRENT_CONTEXT * Added a field "clicks" to the mouse button event which records whether the event is a single click, double click, etc. * The screensaver is now disabled ...

还发现了ANGLE只支持GL ES2.0,无奈之前没搞明白这里面的逻辑,所以直接研究了SDL2中OpenGL ES的相关代码,和OpenGL ES2应该是有区别的。以后有时间再研究吧。 回到顶部 源码下载 SDL2.0源码,选择上面的source code下载下来。 回到顶部 源码分析 作者看SDL源码时是按照认为对自己有用的代码逻辑有目的的进行分析和理解,...
