2018-05-30Work in progress related to invoking events in Automation clientsTor Lillqvist1-0/+34
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.
