This is how QPlatformGLContext also makes it possible to use the QtOpenGL module + withhout using QGLWidget. When using QGLContext::currentContext(), it will ask + QPlatformGLContext for the currentContext. Then a corresponding QGLContext will be returned, + which maps to the QPlatformGLContext. +*/ + +/*! \fn void swapBuffers() + Reimplement in subclass to native swap buffers calls +*/ + +/*! getProcAddress(const QString& procName) + Reimplement in subclass to native getProcAddr calls. + + Note: its convenient to use qPrintable(const QString &str) to get the const char * pointer +*/ + +/*! platformWindowFormat() const + QWidget has the function qplatformWindowFormat(). That function is for the application + programmer to request the format of the window and the context that he wants. + + Reimplement this function in a subclass to indicate what format the glContext actually has. +*/ |
