This signal is sent out to collect variables that can be used to display text in PDF ticket layouts.

Receivers are expected to return a dictionary with globally unique identifiers as keys and more
|

dictionaries as values that contain keys like in the following example::
|
|
|
|
return {
|

"product": {

"evaluate": lambda orderposition, order, event: str(orderposition.item)

}

|
The evaluate member will be called with the order position, order and event as arguments. The event might
|
|
also be a subevent, if applicable.
