Re: [python-win32] How to enable events for Python Active Scripting?

2023-03-13 Thread Wuping Xin via python-win32

Thank you again Mark.

In framework.py, Line 223 - Line 235, I see that it only searches for [source, 
default] interface on the coclass.  That means,  multiple event interface is 
NOT supported for now.

I think I'll have to use "win32com.client.connect.SimpleConnection()" to 
manually create the Source/EventSink connection.

IIRC, each of these objects is a "named item" - so whatever name you use when 
you call AddNamedItem() is the prefix and the suffix is the name of the 
function on the event interface. I'm really not sure how multiple event 
interfaces are supported, if at all.

I'm still not quite sure what you are trying to do. If you are trying to use 
Active Scripting, then things should "just work" in the same way they work for 
other Active Scripting languages. The IE demos show us handling events from IE. 
This all ties together with interfaces described in typelibs and using 
IConnectionPoint etc. In this world you don't implement Python classes which 
derive from EventSink or ScriptItem, you would define a function called 
"ObjectName_EventName"  - eg the "Image_OnClick()" you will find in 
mousetrack.htm.

If you are just trying to use the IConnectionPoint etc without the Active 
Scripting framework, then your best bet is to check out 
win32com\demos\connect.py, and specifically how it uses 
"win32com.client.connect.SimpleConnection()" with the CLSID of an object 
implementing the interface which fires the events.

I'm afraid it has been many years since I've worked on anything related to COM 
or events, so I really don't have great insights into the finer details. I've 
also no additional demos - everything relevant I have is in the repo.
