XConnectable interfaces need a second IID, for the interface "itself",
not the coclass. (I am sure there is some catchy short term for that,
I just can't find it right now.)
Allow several simultaneous sinks for a SwVbaApplication. Not sure in
what case such would be needed, but you never know about 3rd-party
client code, and it's trivial to handle anyway, so why not.
Lots of FIXMEs still. There is likely also a lot of leaks. But at
least an event handler in a simple VBScript script does get invoked.
Note that the changed and added code in extensions/source/ole is
totally unaware of what outgoing ("event") interfaces Writer or Calc
implements, it is all handled generically through the UNO interfaces I
added recently.
One particular thing that needs doing is to actually make Writer (and
Calc) raise this kind of events when necessary. The current code to
invoke events handlers in StarBasic (including StarBasic code running
in "VBA" compaibility) is very much tied to having StarBasic running
(not surprisingly), which of course is not at all the case when it is
an Automation client that is manipulating a Writer or Calc instance
and wants events.
There is demonstration-only code in SwVbaApplication::Documents() to
raise the "Quit" event. (I would have put that in the SwVbaApplication
destructor but that doesn't seem to get called.) That should of course
go away once we invoke other relevant events in appropriate places.
And the "Quit" event needs to be invoked when the application is
quitting.
The whole callback mechanism with IConnectionPoint etc is still partly
a mystery to me. It is entirely possible that even if this now works
for a simple VBScript client, it won't work for (for instance) a VB6
client that might exercise the APIs of the COM interfaces we provide
in a different way.
Add XSinkCaller, for something that perhaps calls one or several
XSinks.
