[PyQt] QOpenGLWindow (PyQt-5.4)

[Trent Huong]

Just a quick follow up, I've tried playing around with it some more. For
example, I've requested a specific OpenGL version and used
"versionFunctions" to get access to the OpenGL functions. However, this
gives new errors, this time:

"ImportError: No module named 'PyQt5._QOpenGLFunctions_4_2_Core'"

Is this just a case of user error or is the support for the new OpenGL
features still incomplete?

import os
import sys

from PyQt5.QtGui import (QOpenGLContext, QOpenGLWindow, QSurfaceFormat)
from PyQt5.QtWidgets import (QApplication,)

class MainWindow(QOpenGLWindow):
    def initializeGL(self):
        self.gl = self.context().versionFunctions()
#QOpenGLContext.currentContext().versionFunctions()
        self.gl.initializeOpenGLFunctions()

        self.gl.glClearColor(1.0, 0.0, 0.0, 1.0)

    def resizeGL(self, w, h):
        pass

    def paintGL(self):
        self.gl.glClear(gl.GL_COLOR_BUFFER_BIT | gl.GL_DEPTH_BUFFER_BIT)

if __name__ == '__main__':
    app = QApplication(sys.argv)

    format = QSurfaceFormat()

    format.setVersion(4, 2)
    format.setProfile(QSurfaceFormat.CoreProfile)

    format.setDepthBufferSize(24);
    format.setStencilBufferSize(8);
    format.setSamples(4)

    window = MainWindow()
    window.setTitle("Hello OpenGL")
    window.setFormat(format)
    window.resize(640, 480)
    window.show()

    sys.exit(app.exec_())

Cheers,
T.H.
