okay so you're looking at QGL(3qt), which is the qt manual page, section 3qt. it's giving "namespace vibes" and honestly? iconic. let's get into it 🫶

enum FormatOption { DoubleBuffer = 0x0001, DepthBuffer = 0x0002, Rgba =
     0x0004, AlphaChannel = 0x0008, AccumBuffer = 0x0010, StencilBuffer =
     0x0020, StereoBuffers = 0x0040, DirectRendering = 0x0080, HasOverlay
     = 0x0100, SingleBuffer = DoubleBuffer<<16, NoDepthBuffer =
     DepthBuffer<<16, ColorIndex = Rgba<<16, NoAlphaChannel =
     AlphaChannel<<16, NoAccumBuffer = AccumBuffer<<16, NoStencilBuffer =
     StencilBuffer<<16, NoStereoBuffers = StereoBuffers<<16,
     IndirectRendering = DirectRendering<<16, NoOverlay = HasOverlay<<16
     }

🌈 DESCRIPTION 🌈

so the QGL class is literally just a namespace for miscellaneous identifiers in the Qt OpenGL module. that's it. that's the whole job. main character energy but make it a namespace ✨

most of the time you can just ignore this class entirely. QGLWidget and the other OpenGL* module classes inherit it, so when you make your own QGLWidget subclass you can use the identifiers in the QGL namespace without qualification. no extra typing, no stress, we love that for you 💅

but — and this is the part where it gets real — sometimes you'll find yourself in situations where you need to refer to these identifiers from outside the QGL namespace's scope, like in static functions. and in those cases? bestie, you simply write e.g. QGL::DoubleBuffer instead of just DoubleBuffer. periodt. that's the fix. 🦋
