Follow-up Comment #15, bug #63748 (project octave):
Response to comment #14
> Do you still need to set those environment variables now that you found an
`opengl32.dll` library that works for you?
If I don't set the environment variables Octave can start but the figure
window is frozen.
> `m_os_context` is not a pointer. It is an object of type QOpenGLContext:
Oops! It was my mistake. m_os_context is an object and not a pointer.
> Are you saying that `GLCanvas` isn't using the `QOpenGLContext` instantiated
in `m_os_context` but some other context? Would we need to "assign"
`m_os_context` as a context for `GLCanvas` somehow?
If I correctly understand GLCanvas has two contexts:
1. The context that is inherited from QOpenGLWidget.
2. m_os_context.
Probably m_os_context is related to some old codes that didn't use
QOpenGLWidget, If I correctly understand.
That part of code is guarded by a macro so a user possibly may switch to other
widget types that don't have a QOpenGLContext as their members.
