I have a FlowDocument as a visual in a RichTextBox that I want to

printFlowDocument = FlowDocument(); etc.....
printFlowDocument.Blocks = visualFlowDocument.Blocks #
Won't work because Blocks is read-only attribute
pDialog.PrintDocument(printFlowDocument.......)
This way works fine:
visualflowDoc = richTextBox.Document
printFlowDoc.Blocks.Add(visualflowDoc.Blocks.LastBlock) #
Visual disappears
pDialog.PrintDocument(printFlowDoc......)
visualFlowDoc.Blocks.Add(printFlowDoc.Blocks.LastBlock) # Visual reappears
The Add method of Blocks, which is a Collection, acts as a "copy and
delete", and I hoped it would act as a Python "list.append". I wonder
if there is a more IronPythonic way to do this or if .Net Collection
is not broadly wrapped by Python list. I know that getitem, setitem,
and iteration work.
The problem is that FlowDocument is a visual element, so if you take
bits of it and put them in another visual element then they aren't going
to be shown in the other one.
IronPython does a lot to make .NET collections behave as Python
collections (you can use the in operator, the del operator etc), but it
doesn't change their fundamental behavior.
All the best,
