num = gl.GenLists(range)
gl.GenLists()
has one argument, range
. It returns an integer n such that range
contiguous empty display lists,
named n, n + 1 , ... , n + range - 1, are created. If range
is 0, if there is no group of range contiguous names
available, or if any error is generated, no display lists are generated, and 0 is returned.
Please consult an OpenGL reference manual for more information.
#GL_INVALID_VALUE
is generated if range
is negative.
#GL_INVALID_OPERATION
is generated if gl.GenLists()
is executed between the execution of gl.Begin() and the corresponding execution of gl.End() .
