# 1. Create the window
#
window = WindowParent().create('Radio Groups', (0, 0))
#
# 2. Create a horizontal split to contain the groups
#

# 3. Create vertical splits, one for each group
#

# 4. Create individual radio buttons, each in their own split

# 5. Define the grouping for the radio buttons.
# Note: this doesn't have to be the same as the
# grouping is splits (although it usually is).
# Also set the 'hook' procedure for each button
#

for b in list2:
b.group = list2

for b in list3:

#
# 6. Select a default button in each group
#
b11.select(1)
b22.select(1)
b33.select(1)
#
# 6. Realize the window
#
window.realize()
#
# 7. Dispatch events until the window is closed
#
MainLoop()
#
# 8. Report final selections
#

if b23.selected: print '2.3'
if b31.selected: print '3.1'
if b32.selected: print '3.2'
if b33.selected: print '3.3'
# My 'hook' procedure
# This is placed as 'hook' attribute on each button.
# The example just prints the title of the selected button.
