I'm working on a simple GTK+ wrapper around the flash Pandora Radio
player (Pandora.com).
It's very basic right now but I've got it almost working.
I'm using gtkmozembed to fetch and use the player and dbus to detect
multimedia keys.
The only problem I'm having is that the mozembed widget doesn't seem
to recognize the fake keypress event sent to it.
CODE
#!/usr/bin/env python
import gtk
import gtkmozembed
import dbus
from dbus.mainloop.glib import DBusGMainLoop
class Wrapper:
def __init__(self):
# Set-up the wrapper for the player
self.win = gtk.Window() # Create a new GTK window called 'win'
self.win.set_title("Pandora Player") # Set the title of the
window
self.win.set_icon_from_file('favicon.ico') # Set the window
icon to a web browser icon
self.win.set_position(gtk.WIN_POS_CENTER) # Position the
window in the centre of the screen
self.win.connect("destroy", self.close_window) # Connect the
'destroy' event to the 'CloseWindow' function, so that the app will
quit properly
# Handle media keys under Gnome
DBusGMainLoop(set_as_default=True)
bus = dbus.Bus(dbus.Bus.TYPE_SESSION)
settings = bus.get_object('org.gnome.SettingsDaemon', '/org/
gnome/SettingsDaemon') # Connect to gnome settings D-Bus
settings.connect_to_signal("MediaPlayerKeyPressed",
self.action)
# Create the browser widget
gtkmozembed.set_profile_path("/tmp", "simple_browser_user") #
Set a temporary Mozilla profile (works around some bug)
self.mozbrowser = gtkmozembed.MozEmbed() # Create the browser
widget
# Set-up the browser widget before we display it
self.win.add(self.mozbrowser) # Add the 'mozbrowser' widget to
the main window 'win'

tuner_8_2_0_2_pandora.swf") # Load Pandora
