glfw 1.6.0

A ctypes-based wrapper for GLFW3.

This module provides Python bindings for GLFW (on GitHub: glfw/glfw). It is a ctypes wrapper which keeps very close to the original GLFW API, except for:

• function names use the pythonic words_with_underscores notation instead of camelCase
• GLFW_ and glfw prefixes have been removed, as their function is replaced by the module namespace
• structs have been replaced with Python sequences and namedtuples
• functions like glfwGetMonitors return a list instead of a pointer and an object count
• Gamma ramps use floats between 0.0 and 1.0 instead of unsigned shorts (use glfw.NORMALIZE_GAMMA_RAMPS=False to disable this)
• GLFW errors are reported as glfw.GLFWError exceptions if no error callback is set (use glfw.ERROR_REPORTING=False to disable this)
• instead of a sequence for GLFWimage structs, PIL/pillow Image objects can be used

Installation

pyGLFW can be installed using pip:

pip install glfw

For Windows users, the GLFW shared library is included in the Python wheels. Linux and macOS users need to install the library themselves and should compile GLFW from source (use -DBUILD_SHARED_LIBS=ON).

pyGLFW will search for the library in a list of search paths (including those in LD_LIBRARY_PATH on Linux and DYLD_LIBRARY_PATH on macOS). If you want to use a specific library, you can set the PYGLFW_LIBRARY environment variable to its path.

Example Code

The example from the GLFW documentation ported to pyGLFW:

import glfw

def main():
    # Initialize the library
    if not glfw.init():
        return
    # Create a windowed mode window and its OpenGL context
    window = glfw.create_window(640, 480, "Hello World", None, None)
    if not window:
        glfw.terminate()
        return

    # Make the window's context current
    glfw.make_context_current(window)

    # Loop until the user closes the window
    while not glfw.window_should_close(window):
        # Render here, e.g. using pyOpenGL

        # Swap front and back buffers
        glfw.swap_buffers(window)

        # Poll for and process events
        glfw.poll_events()

    glfw.terminate()

if __name__ == "__main__":
    main()
