There is no setup.py file, so installation via pip is not currently possible.

On python3, glfw.glfwGetVideoMode(monitor) will fail with the following error:

File "/home/drluke/prog/cockamamie/pyglfw/glfw.py", line 576, in glfwGetVideoMode
    return (c_mode.width,
AttributeError: 'LP_GLFWvidmode' object has no attribute 'width'

One working fix is to change the function from

def glfwGetVideoMode(monitor):
    _glfw.glfwGetVideoMode.restype = POINTER(GLFWvidmode)
    c_mode = _glfw.glfwGetVideoMode(monitor)
    return (c_mode.width,
            c_mode.height,
            c_mode.redBits,
            c_mode.blueBits,
            c_mode.greenBits,
            c_mode.refreshRate )

to

def glfwGetVideoMode(monitor):
    _glfw.glfwGetVideoMode.restype = POINTER(GLFWvidmode)
    c_mode = _glfw.glfwGetVideoMode(monitor)
    return (c_mode[0].width,
            c_mode[0].height,
            c_mode[0].redBits,
            c_mode[0].blueBits,
            c_mode[0].greenBits,
            c_mode[0].refreshRate )

I am not certain if this breaks functionality for python2 though, so I didn't yet submit a pullrequest.

Only one letter shown as title when creating a window on Windows. Except that, everything works fine. If I deleted the explicit title parameter, only a G is shown at the position of the title.
How to solve that?
The system is Windows 10 and with Python 3.7.3. The version of GLFW is 3.3.

Hi, first of all, thanks for maintaining this wrapper. I just tried to get full screen mode working under Mac OS X (El Capitan) and I'm getting a segfault when trying to use the monitor information functions. This python code will crash:

import glfw
glfw.glfwInit()
monitor = glfw.glfwGetPrimaryMonitor()
print("Monitor:", monitor, type(monitor))
print(glfw.glfwGetVideoModes(monitor))

This will print:

Monitor: 441455392 <class 'int'>
Segmentation fault: 11

I'm finding it a bit strange that monitor is listed with type 'int'... shouldn't it be size_t or similar?

The equivalent C++ code works fine. I'll try it on a 64 bit Linux machine tomorrow.

What file should _glfw_file point to?
_glfw = ctypes.CDLL(_glfw_file)

Or the GLFW_LIBRARY system variable if you will.
