On the internet I found code that shows how to do it, in VB. Apparently
the CommandBar controls have their own way in which they expose events, you
have to pass them to the 'word.VBE.Events.CommandBarEvents()' function, and that
will deliver the events then:
word = comtypes.client.CreateObject("Word.Application")
word.Visible = 1
tb = word.CommandBars("Standard")
btn = tb.Controls[1]
evt = word.VBE.Events.CommandBarEvents(btn)
from comtypes.gen import VBIDE
comtypes.client.ShowEvents(evt,
interface=VBIDE._dispCommandBarControlEvents)
Unfortunately you have to supply the event interface in the ShowEvents call,
because comtypes currently is not able to find out this interface itself.
I have already fixed this bug in SVN, so in the next version (or if you
grab the svn version) you should be able to use:
comtypes.client.ShowEvents(evt)
Please note that the comtypes.gen.VBIDE module is automatically generated;
there is no need to call GetModule() in your code (at least that was the case
for me,
but I only have Word97 installed).
