kv language designing with anchorlayout

When designing a Kivy menu with the kv language I run into troubles with the anchorlayout object.
It seems that you need to put every object inside a achorlayout which itself is part of a anchorlayout.

Sounds a bit vague so an example should do:

[sourcecode language=”text”]
<topbox>:
AnchorLayout:
id: topmenu
anchor_x: ‘center’
anchor_y: ‘top’

BoxLayout:
orientation: ‘horizontal’
AnchorLayout:
anchor_x: ‘left’
anchor_y: ‘top’
padding: 8
Button:
id: infobutton
size: (48, 48)
size_hint: None, None
background_normal: ‘info_button.png’
background_down: ‘info_button.png’
on_press: root.on_button_clicked("info")

AnchorLayout:
anchor_x: ‘center’
anchor_y: ‘top’
padding: 8
BoxLayout:
padding: 0
spacing: 4
size: (300, 48)
size_hint: None, None
orientation: ‘horizontal’
AnchorLayout:
anchor_x: ‘center’
anchor_y: ‘top’
Button:
size: (48, 48)
size_hint: None, None
background_normal: ‘star1.png’
on_press: root.on_button_clicked("star1")
AnchorLayout:
anchor_x: ‘center’
anchor_y: ‘top’
Button:
size: (48, 48)
size_hint: None, None
background_normal: ‘star1.png’
on_press: root.on_button_clicked("star2")
AnchorLayout:
anchor_x: ‘right’
anchor_y: ‘top’
padding: 8
Button:
id: quitbutton
size: (48, 48)
size_hint: None, None
background_normal: ‘quit_button.png’
background_down: ‘quit_button_ro.png’
on_press: root.on_quit_button_clicked()

[/sourcecode]

Python script to download youtube vids

[sourcecode language=”python”]

import sys, os, random, time

if len(sys.argv) < 3:
print "Usage: youtube_pl2vids [playlist.html] [destination directory]"
sys.exit(1)

source = sys.argv[1]
dest = sys.argv[2]
urllines = []
f = open(os.path.join(dest, ‘youtube.dl’), ‘w’)
for line in open(source, ‘r’).readlines():
if ‘<a href="/watch?v=’ in line and ‘class="tile-link-block video-tile"’ in line:
url = "http://www.youtube.com" + line.split(‘&amp’)[0].split(‘<a href="’)[1]
f.write(url + ‘n’)
urllines.append(url)
f.close()
print urllines
# we assume youtube-dl is installed
for line in urllines:
os.system(‘youtube-dl -t –max-quality 22 %s’ % line)
s = random.randint(1, 6)
print "sleeping %s secs" % s
time.sleep(s)
[/sourcecode]

Create a playlist in your youtube account.
Download the playlist page and save it as html.
Install youtube-dl: sudo apt-get install youtube-dl
Start youtube_pl2vids.py script with the path of the playlist.html.
For example: python youtube_pl2m3u.py playlist.html vidsdirectory
Your videos will be downloaded and placed in the ‘vidsdirectory’

The script will sleep for some random seconds between downloading the vids to simulate human interaction.
