Maximize WebDriver (Selenium 2) in Python

Question

I'm attempting to write a simple script that checks if I have any gmail emails labeled SOMETHING and then opens a firefox browser window to a login page, after which it goes to something else.

Here's what I'm doing:

from selenium import webdriver from selenium.webdriver.support.ui import WebDriverWait from selenium.common.exceptions import TimeoutException from selenium.webdriver.common.action_chains import ActionChains import time, imaplib  Eusername = "[email protected]" Epassword = "password1"  username = "username" password = "password2"  imaps = imaplib.IMAP4_SSL('imap.gmail.com','993') imaps.login(Eusername,Epassword)  imaps.select('SOMETHING') status, response = imaps.status('SOMETHING', "(UNSEEN)") unreadcount = int(response[0].split()[2].strip(').,]'))  while unreadcount > 0:     driver = webdriver.Firefox()     driver.get('http://wwww.SomeURL.com/some_login.html')     time.sleep(3)     inputElement = driver.find_element_by_name("user")     inputElement.send_keys(username)     inputElement = driver.find_element_by_name("pw")     inputElement.send_keys(password)     inputElement.submit()     time.sleep(1)     driver.get('http://www.SomeURL.com/somethingelse.html')     imaps.select('SOMETHING')     typ ,data = imaps.search(None,'UnSeen')     imaps.store(data[0].replace(' ',','),'+FLAGS','\Seen') 

I've spent hours search and haven't found a solution to maximize the browser window. Elsewhere i've read that there is a windowMaximize() or window_maximize(), but have not been able to get them to work since every configuration I've tried claims it doesn't exist for whatever module.

I only know a little python, and am working in Mac OSX

Answer 1

I've never used this functionality before, so I tried it out.

driver.maximize_window() 

This seems to work fine - unless I am using Chrome. I'm not sure if this is a defect, as it works flawlessly in IE9 and Firefox.

edit: This is a feature which has yet to be implemented in Chromedriver -= Link to issue =-

edit (8 years later): Apparently this is working in Chrome on Linux and Windows - so, yay! I haven't tested it, but I am optimistic since it has been nearly a decade since the original answer was provided.

Even if this is old, it's cool to know that you can always get values from system then set it by hand. This would work on every webdriver you use.

#!/usr/bin/env python #! -*- coding: utf-8 -*-  import selenium from selenium import webdriver  import os, sys, time  import wx  print "example with maximize_window()" nav = webdriver.Firefox() nav.maximize_window() time.sleep(3) nav.quit()  print 'example with fixed set_window_size("1024", "768")' nav = webdriver.Firefox() nav.set_window_size("1024", "768") time.sleep(3) nav.quit()  print "example grabbing size with wx (wxWidgets)" nav = webdriver.Firefox() app = wx.App(False) #wx.App(False) # the wx.App object must be created first. screenxy = wx.GetDisplaySize()  # returns a tuple nav.set_window_size(screenxy[0], screenxy[1]) time.sleep(3) nav.quit()   sys.exit(0)
