Does it exist a list of all events the IDE can handle, please ?
The IDE does NOT handle events... of it's OWN!
The IDE exposes the events that each view/custom view/library expose to the IDE
i.e: Many CustomViews have custom events, that may even not be a "standard" event from the views it is composed of, and even not expose any of the "standard" views events.
Some views may have undocumented events, or even have "not to be used" events that were exposed by smelly-code.
... and I don't think that we have answered his original (and interesting) question.
He's question, as explained, is wrong...
So, I am wondering where I could find the information.
You need to look into the targeted view's documentation, not only here on the forum, but also in its "original" java ...
Reflection and JavaObject libs were created exactly with the purpose of helping expose event's, methods and props that may sometimes not be exposed in the B4X library.
