BTW, changing part of my modified version of your example as follows,
I can confirm your earlier statement that importing pyglet.gl has a
side effect (locking the window re dragging) which is not mediated by
its redefinition of all the gl*/GL* globals:
def _import_gl_raw(use_pyglet):
global glMultMatrixf, glClearColor, glShadeModel, glTranslated,
glClear
global glColor3f, glLoadIdentity, glScalef, glVertex3f, glNormal3f
global glBegin, glEnd, glFlush, GLfloat, glViewport, glMatrixMode,
glFrustum
global GL_TRIANGLES, GL_FLAT, GL_COLOR_BUFFER_BIT, GL_PROJECTION,
GL_MODELVIEW
global glmult
if use_pyglet:
## from pyglet.gl import *
from pyglet.gl import glMultMatrixf, glClearColor,
glShadeModel, glTranslated, glClear
from pyglet.gl import glColor3f, glLoadIdentity, glScalef,
glVertex3f, glNormal3f
from pyglet.gl import glBegin, glEnd, glFlush, GLfloat,
glViewport, glMatrixMode, glFrustum
from pyglet.gl import GL_TRIANGLES, GL_FLAT,
GL_COLOR_BUFFER_BIT, GL_PROJECTION, GL_MODELVIEW
def glmult(l):
return glMultMatrixf( (GLfloat * len(l))(*l) )
## pwin = pyglet.window.Window(resizable=True)
else:
## from OpenGL.GL import *
from OpenGL.GL import glMultMatrixf, glClearColor,
glShadeModel, glTranslated, glClear
from OpenGL.GL import glColor3f, glLoadIdentity, glScalef,
glVertex3f, glNormal3f
from OpenGL.GL import glBegin, glEnd, glFlush, GLfloat,
glViewport, glMatrixMode, glFrustum
from OpenGL.GL import GL_TRIANGLES, GL_FLAT,
GL_COLOR_BUFFER_BIT, GL_PROJECTION, GL_MODELVIEW
def glmult(l):
return glMultMatrixf( l )
def _import_gl():
_import_gl_raw( 'PYGLET' in os.environ) # do the import pyglet.gl
_import_gl_raw( False) # then change the globals gl*/GL* back to
what they were (bug still present on my Mac)
