Example normal system theme colors :


import gtk    
self.settings = gtk.settings_get_default()
self.settings.set_property("gtk-theme-name", "Adwaita-dark")

Example after 3 lines of code :


There is no need for this :
themedir = "/usr/share/themes"
userthemedir = os.path.join(os.path.expanduser("~"), ".themes")

In Gscreen this code is for changing system theme, Gmoccapy uses almost the same code :
# get the system wide theme
        settings = gtk.settings_get_default()
        settings.props.gtk_button_images = True
        self.data.system_theme = settings.get_property("gtk-theme-name")
        # check for a local theme gtkrc file
        localtheme = os.path.join(CONFIGPATH,'%s_theme'%self.skinname)
        if os.path.exists(localtheme):
            print 'local theme path found'
            self.data.local_theme = 'Link to %s_theme'% self.skinname
            # make ~/.themes - quietly ignore the error if it exists
            try:
                os.makedirs(userthemedir)
            except OSError as exception:
                if exception.errno != errno.EEXIST:
                    raise
            # create systemlink because one can't store themes in an arbitrary folder.
            if not os.path.exists(userthemedir+'/%s'%self.data.local_theme):
                os.symlink(localtheme,userthemedir+'/%s'%self.data.local_theme)
            settings = gtk.settings_get_default()
            settings.set_string_property("gtk-theme-name", self.data.local_theme, "")
        else:
            self.data.local_theme = None

This is because Gscreen and Gmoccapy allow you to have your special theme in the config folder rather then the system folder.
Some CNC themes are not suitable for the system.
