I'm trying to get the 3D Space Navigator (http://www.3dconnexion.com/) to work in Python. I quickly found a solution using comtypes on the 3DConnexion developer forum: http://www.3dconnexion.com/forum/viewtopic.php?t=984&start=30
However that solution only works with comtypes version 0.2.1. Any newer version will result in the events not registering. This is the output I get from the GetEvents() function when using version 0.2.1: Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import logging >>> logging.basicConfig(level=logging.DEBUG) >>> class EventHandler: ... def __getattr__(self, name): ... print name ... >>> from comtypes.client import * DEBUG:comtypes:CoInitializeEx(None, 2) >>> x = CreateObject("TDxInput.Device") DEBUG:comtypes.client:TDxInput.Device -> {82C5AB54-C92C-4D52-AAC5-27E25E22604C} DEBUG:comtypes.client:CoCreateInstance({82C5AB54-C92C-4D52-AAC5-27E25E22604C}, clsctx=None, interface=None) INFO:comtypes.client:wrap(<POINTER(IUnknown) object c108a0>) INFO:comtypes.client:Does implement IProvideClassInfo INFO:comtypes.client:Implements default interface from typeinfo <class 'comtypes.gen._7858B9E0_5793_4BE4_9B53_661D922790D2_0_1_0.ISimpleDevice'> INFO:comtypes.client:Final result is <POINTER(ISimpleDevice) object c2c080> >>> x.Connect() 0 >>> test = GetEvents(x.sensor, EventHandler) INFO:comtypes.client:wrap_outparam(<POINTER(ISensor) object c108a0>) DEBUG:comtypes.client:<POINTER(ISensor) object c108a0> using sinkinterface <class 'comtypes.gen._7858B9E0_5793_4BE4_9B53_661D922790D2_0_1_0._ISensorEvents'> DEBUG:comtypes.client:Start advise <class 'comtypes.gen._7858B9E0_5793_4BE4_9B53_661D922790D2_0_1_0._ISensorEvents'> DEBUG:comtypes._comobject:<comtypes.client.DispEventReceiver object at 0x00C12590>.QueryInterface({E6929A4A-6F41-46C6-9252-A8CC53472CB1}) -> S_OK DEBUG:comtypes._comobject:1 active COM objects: Added <comtypes.client.DispEventReceiver object at 0x00C12590> DEBUG:comtypes._comobject:<comtypes.client.DispEventReceiver object at 0x00C12590>.AddRef() -> 1 DEBUG:comtypes.client:End advise <class 'comtypes.gen._7858B9E0_5793_4BE4_9B53_661D922790D2_0_1_0._ISensorEvents'> DEBUG:comtypes._comobject:<comtypes.client.DispEventReceiver object at 0x00C12590>.Release() -> 0 DEBUG:comtypes._comobject:0 active COM objects: Removed <comtypes.client.DispEventReceiver object at 0x00C12590> >>> And this is the output I get when I use version 0.5.1: Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import logging >>> logging.basicConfig(level=logging.DEBUG) >>> from comtypes.client import * DEBUG:comtypes:CoInitializeEx(None, 2) >>> x = CreateObject("TDxInput.Device") DEBUG:comtypes.client:TDxInput.Device -> {82C5AB54-C92C-4D52-AAC5-27E25E22604C} DEBUG:comtypes.client:CoCreateInstance({82C5AB54-C92C-4D52-AAC5-27E25E22604C}, clsctx=None, interface=None) DEBUG:comtypes.client:GetBestInterface(<POINTER(IUnknown) ptr=0x9f3fc0 at c0e3f0>) DEBUG:comtypes.client:Does implement IProvideClassInfo DEBUG:comtypes.client:Default interface is {CB3BF65E-0816-482A-BB11-64AF1E837812} DEBUG:comtypes:Release <POINTER(IUnknown) ptr=0x9f3fc0 at c14080> DEBUG:comtypes.client._generate:GetModule(TLIBATTR(GUID={7858B9E0-5793-4BE4-9B53-661D922790D2}, Version=1.0, LCID=0, FLags=0x8)) DEBUG:comtypes.client:Implements default interface from typeinfo <class 'comtypes.gen._7858B9E0_5793_4BE4_9B53_661D922790D2_0_1_0.ISimpleDevice'> DEBUG:comtypes.client:Final result is <POINTER(ISimpleDevice) ptr=0x9f3fc0 at c14d00> DEBUG:comtypes:Release <POINTER(IProvideClassInfo) ptr=0x9f68a8 at c0ed00> DEBUG:comtypes:Release <POINTER(ITypeInfo) ptr=0x24c5f4 at c0eda0> DEBUG:comtypes:Release <POINTER(ITypeInfo) ptr=0x24c620 at c0ee90> DEBUG:comtypes:Release <POINTER(ITypeLib) ptr=0x24bd88 at c0ef80> DEBUG:comtypes:Release <POINTER(IUnknown) ptr=0x9f3fc0 at c0e3f0> >>> x.Connect() 0 >>> test = ShowEvents(x.sensor) DEBUG:comtypes.client:wrap_outparam(<POINTER(ISensor) ptr=0x9f2170 at c14d50>) DEBUG:comtypes.client._events:<POINTER(ISensor) ptr=0x9f2170 at c14d50> using sinkinterface <class 'comtypes.gen._7858B9E0_5793_4BE4_9B53_661D922790D2_0_1_0._ISensorEvents'> DEBUG:comtypes:Release <POINTER(IProvideClassInfo2) ptr=0x9f2194 at a91530> # event found: _ISensorEvents_SensorInput DEBUG:comtypes.client._events:Start advise <class 'comtypes.gen._7858B9E0_5793_4BE4_9B53_661D922790D2_0_1_0._ISensorEvents'> DEBUG:comtypes._comobject:<comtypes.client._events.Sink object at 0x00C52990>.QueryInterface({E6929A4A-6F41-46C6-9252-A8CC53472CB1}) -> S_OK DEBUG:comtypes._comobject:1 active COM objects: Added <comtypes.client._events.Sink object at 0x00C52990> DEBUG:comtypes._comobject:<comtypes.client._events.Sink object at 0x00C52990>.AddRef() -> 1 DEBUG:comtypes:Release <POINTER(IConnectionPointContainer) ptr=0x9f2174 at c843a0> DEBUG:comtypes:Release <POINTER(ISensor) ptr=0x9f2170 at c14d50> >>> I believe, that this is enough output, because I believe the line "DEBUG:comtypes:Release <POINTER(ISensor) ptr=0x9f2170 at c14d50>" shows, where the bug originates.
