Ubuntu – How to force a redraw using python in gtk3

In Glade:

1. Select the spinbutton.
2. Click the button next to the "Adjustment" text entry that has "..." in it.
3. In the window that appears click "New."
4. Select the "adjustment1" widget from above.
5. From there you can change value for a default value, minimum value, maximum value, and step increment.

You can also change those values from code, the class refrence can be found here: gtk.SpinButton.

Edit: You can get the maximum and minimum values using the following code:

(min, max) = spinbutton.get_range()

where min is minimum value, max is maximum value, and spinbutton is the spin button widget. You can also set it using the following:

spinbutton.set_range(min, max)

After looking at the source to libaccountsservice you actually have to wait for the user to be loaded before accessing the user object. This acheives the result:

from gi.repository import AccountsService, GLib

current_user = GLib.get_user_name()
user = AccountsService.UserManager.get_default().get_user(current_user)
def is_loaded_cb(user, param):
    print user.get_icon_file()
user.connect('notify::is-loaded', is_loaded_cb)

main_loop = GLib.MainLoop()
main_loop.run()

Alternatively, you can contact the accounts service directly and synchronously over D-Bus:

from gi.repository import GLib, Gio

current_user = GLib.get_user_name ()
bus = Gio.bus_get_sync (Gio.BusType.SYSTEM, None)
result = bus.call_sync ('org.freedesktop.Accounts',
                        '/org/freedesktop/Accounts',
                        'org.freedesktop.Accounts',
                        'FindUserByName',
                        GLib.Variant ('(s)', (current_user,)),
                        GLib.VariantType.new ('(o)'),
                        Gio.DBusCallFlags.NONE,
                        -1,
                        None)
(path,) = result.unpack ()

result = bus.call_sync ('org.freedesktop.Accounts',
                        path,
                        'org.freedesktop.DBus.Properties',
                        'GetAll',
                        GLib.Variant ('(s)', ('org.freedesktop.Accounts.User',)),
                        GLib.VariantType.new ('(a{sv})'),
                        Gio.DBusCallFlags.NONE,
                        -1,
                        None)
(props,) = result.unpack ()
print props['IconFile']
print props['RealName']

If you want to set the icon file you need to call the appropriate method:

result = bus.call_sync ('org.freedesktop.Accounts',
                       path,
                       'org.freedesktop.Accounts.User',
                       'SetIconFile',
                       GLib.Variant ('(s)', ('/tmp/somefile.png',)),
                       GLib.VariantType.new ('()'),
                       Gio.DBusCallFlags.NONE,
                       -1,
                       None)

If you need to use any other methods, browse the D-Bus interface using D-Feet (in the software center).
