How to get the desktop resolution in Mac via Python?

Question

Trying to write a python application that downloads images from an RSS feed, and makes a composite background. How do I get the current desktop resolution on Mac OS X (leopard?)

Answer 1

As usual, using features that are binded to an OS is a very bad idea. There are hundred of portable libs in Python that give you access to that information. The first that comes to my mind is of course pygame :

import pygame
from pygame.locals import *

pygame.init()
screen = pygame.display.set_mode((640,480), FULLSCREEN)
x, y = screen.get_size()

But I guess cocoa do just as good, and therefor wxpython or qt is your friend. I suppose on Windows you did something like this :

from win32api import GetSystemMetrics
width = GetSystemMetrics [0]
height = GetSystemMetrics [1]

Sure it's easier, but won't work on Mac, Linux, BSD, Solaris, and probably nor very later windows version.

Answer 2

With Pyobjc something like this should work. Pyobjc comes with Leopard.

from AppKit import NSScreen

print NSScreen.mainScreen().frame()
