I'm trying to translate the following VB code into Python and not
sure how
to create an array of variants.
All variables in Python are effectively variants - variables that can
store any type. So an array of variants equates to a Python list
VB Code:
Sub SetXdata()
def SetXData():
Dim lineObj As AcadLine
Set lineObj = ThisDrawing.ModelSpace.Item(0)
lineObj = ThisDrawing.ModelSpace.Item(0)
Where ThisDrawing.ModelSpace.Item(0) is s0ome kind of
data structure you have defined elsewhere. Or fetch using COM.
Dim DataType(0 To 1) As Integer
Dim Data(0 To 1) As Variant
DataType = []
Data = []
But it looks like you are trying to fake a dictionary - although VB
has dictionaries!
DataType(0) = 1001: Data(0) = "Test_Application"
DataType(1) = 1070: Data(1) = 600
Data = {'Test_application' : 1001, 600 : 1070}
lineObj.SetXdata DataType, Data
lineObj.SetXdata( Data )
Python code
import array
import comtypes.client
def SetXData():
activedoc =
comtypes.client.GetActiveObject("AutoCAD.Application").ActiveDocument
line = activedoc.ModelSpace.Item(0)
dataType = array.array('i', [1001, 1070])
dataValue = array.array('?', ['Test_Application', 600]) #What
should I
use
for the type code?
line.SetXData(dataType, dataValue)
Here's the snag with the dictionary approach so its back to
two lists. I wouldn't use the array module just lists.
It might be enough to just pass DataType and Data as two lists
into the COM object. I don't know enough about Python's COM
integration to be sure that it will sort it all out though. But I
suspect
it will.
