Next Line?

[Dan Gentry]

I think I'm missing something obvious. Although I've looked through
the docs and examples, I can't seem to find a good example for a multi-
line band. In my report, I've defined a ReportGroup like so:

groups = [
ReportGroup(attribute_name='b2c_class.id',
band_header=ReportBand(
height=.854*inch,
auto_expand_height = True,
elements=[
ObjectValue(attribute_name='class_name', left=0,
top=0.18*inch, width=BAND_WIDTH,
get_value=lambda instance:
str(instance.b2c_class.class_name),
style={'fontName': 'Helvetica-Bold',
'fontSize': 12, 'alignment': TA_CENTER}),
ObjectValue(attribute_name='session',
left=0.5*inch, top=0.36*inch, width=BAND_WIDTH,
get_value=lambda instance: 'Time: ' +
str((format_time_hm(instance.b2c_class.session.start_time) if
instance.b2c_class.session.start_time else '')
+ (' - ' +
format_time_hm(instance.b2c_class.session.stop_time) if
instance.b2c_class.session.stop_time else '')),
style={'fontName': 'Helvetica-Bold',
'fontSize': 9}),
ObjectValue(attribute_name='location',
left=3*inch, top=0.36*inch, width=BAND_WIDTH,
get_value=lambda instance: ('Location: ' +
str(instance.b2c_class.location)),
style={'fontName': 'Helvetica-Bold',
'fontSize': 9}),
],
borders={'bottom': True},
)
),
]

Works fine sometimes. However, if the class_name value needs more
than one line to print, it writes over the next line of text. Instead
of hard coding a top attribute value, I'd like to use something like
'next_line' or 'same_line' as needed that would take into account the
font height, amount of text, etc, used in the previous line or group.

Could someone steer me in the right direction?

Thanks,
