Why create one when you can just import one from python.
Here is some code from our program. we recently added a custom web
browser choice if the user wishes rather than the the default web
browser that python knows about. dprint() is our utils print function
that prints to stderr if the debug flag was passed at startup.
[code]
# if using gnome, see if we can import it
try:
import gnome
try:
import gnomevfs
except: # try the depricated module
import gnome.vfs
except ImportError:
# no gnome module
#print >>stderr, ('Module "gnome" not found. '
# 'You will not be able to use gnome to open web pages.')
dprint('LOADERS: Module "gnome" not found. '
'You will not be able to use gnome to open web pages.')
# get the standard webbrowser module
try:
import webbrowser
except ImportError:
#print >>stderr, ('Module "webbrowser" not found. '
# 'You may not be able to open web pages.')
dprint(' * LOADERS: Module "webbrowser" not found. You may not be able to
open web pages.')
def load_web_page(name, prefs):
"""Try to load a web page in the default browser"""
dprint("LOADERS: load_web_page(); starting browser thread")
browser = web_page(name, prefs)
browser.start()
return
def load_help_page(name, prefs):
"""Load a locale-specific help page with the default browser."""
dprint("LOADERS: load_help_page: %s" % name)
lc = prefs.globals.LANG
if not lc: lc = "en"
helpdir = os.path.join(prefs.DATA_PATH, 'help')
if os.access(os.path.join(helpdir, lc, name), os.R_OK):
pagename = "file://" + os.path.join(helpdir, lc, name)
elif os.access(os.path.join(helpdir, lc.split('_')[0], name), os.R_OK):
pagename = "file://" + os.path.join(helpdir, lc.split('_')[0], name)
elif os.access(os.path.join(helpdir, "en", name), os.R_OK):
pagename = "file://" + os.path.join(helpdir, "en", name)
else:
dprint(" * LOADERS: failed to find help file '%s' with LANG='%s'!" %
(name, prefs.globals.LANG))
return False
load_web_page(pagename, prefs)
class web_page(threading.Thread):
"""Try to load a web page in the default browser"""
def __init__(self, name, prefs):
dprint("LOADERS: web_page.__init__()")
threading.Thread.__init__(self)
self.name = name
self.prefs = prefs
self.setDaemon(1) # quit even if this thread is still running
def run(self):
dprint("LOADERS: web_page.run()")
if self.name == '' or self.name == None:
return
if self.prefs.globals.use_custom_browser:
command = self.prefs.globals.custom_browser_command
if '%s' not in command: command += ' %s'
browser = webbrowser.GenericBrowser(command)
try:
browser.open(self.name)
except:
dprint("LOADERS: failed to open '%s' with browser command '%s'"
% (self.name, command))
else:
try:
gnome.url_show(self.name)
except:
dprint("LOADERS: Gnome failed trying to open: %s" %self.name)
try:
webbrowser.open(self.name)
except:
dprint("LOADERS: webbrowser failed trying to open: %s --
giving up" %self.name)
pass
dprint("LOADERS: Browser call_completed for: %s" %self.name)
