container
Container classes are classes that are used to transport data between the
model thread and the GUI thread.
When complex data sets need to be visualized (eg.: charts, intervals), built-in
python types don’t contain enough information, while dictionary like structures
are not self documented. Hence the need of specialized container classes to
transport this data between the model and the GUI.
To use this classes :
- On your model class, define properties returning a container class
- In the admin class, add the property to the list of fields to visualize, and
specify its delegate
eg:
class MyEntity(Entity):
@property
def my_interval(self):
return IntervalsContainer()
- class Admin(EntityAdmin):
- form_display = [‘my_interval’]
field_attributes = dict(my_interval=dict(delegate=IntervalsDelegate))
-
class camelot.container.Arrow(x, y, width)[source]
Container to describe arrows
-
class camelot.container.Container[source]
Top level class for all container classes
-
class camelot.container.Interval(begin, end, name='', color=2)[source]
Helper class for IntervalsContainer, specifications for one interval
-
class camelot.container.IntervalsContainer(min, max, intervals)[source]
Containter to hold interval data
eg : representing the time frame of 8pm till 6am that someone was at work using an hourly
precision :
intervals = IntervalsContainer(0, 24, [Interval(8, 18, ‘work’)])
