As for question, I am trying to adjust Grid Map labels via Arcobjects with Python. For now I do have:
from comtypes.client import CreateObject, GetModule
import arcpy
def CType(obj, interface):
"""Casts obj to interface and returns comtypes POINTER or None"""
try:
newobj = obj.QueryInterface(interface)
return newobj
except:
return None
def NewObj(MyClass, MyInterface):
"""Creates a new comtypes POINTER object where\n\
MyClass is the class to be instantiated,\n\
MyInterface is the interface to be assigned"""
from comtypes.client import CreateObject
try:
ptr = CreateObject(MyClass, interface=MyInterface)
return ptr
except:
return None
esriCarto = GetModule(r"C:\Program Files (x86)\ArcGIS\Desktop10.0\com\esriCarto.olb")
esriCartoUI = GetModule(r"C:\Program Files (x86)\ArcGIS\Desktop10.0\com\esriCartoUI.olb")
esriMapUI = GetModule(r"C:\Program Files (x86)\ArcGIS\Desktop10.0\com\esriArcMapUI.olb")
esriFrame = GetModule(r"C:\Program Files (x86)\ArcGIS\Desktop10.0\com\esriFramework.olb")
arcpy.SetProduct('Arcinfo')
pApp = NewObj(esriFrame.AppROT, esriFrame.IAppROT).Item(0)
pDoc = pApp.Document
pMxDoc = CType(pDoc, esriMapUI.IMxDocument)
pLayout = pMxDoc.PageLayout
pGraphContLayout = CType(pLayout, esriCarto.IGraphicsContainer)
iFrameElement = pGraphContLayout.FindFrame(pMxDoc.ActiveView.FocusMap)
As far as I understand, iFrameElement is an interface of an abstract class from which I need to inherit attributes (pointer) to MapFrame object. How do I do that? How do it get to object with IMapGrids interface. Any suggestions?
