I haven't found an equivalent for EVT_MOUSE_EVENTS in a
wxEVT_MOUSE_EVENTS form that would be usable for Bind and Connect.
Have I missed it or if not is there a reason why we don't have one.
Regards, John

There is: it's not a single event but a macro expanding into ~20 or so
other event table macros. And this can't be done with Bind(), a single call
to it can be used only to bind a handler for a single event type.

wxEVT_MOUSE_EVENTS but did find EVT_MOUSE_EVENTS in event.h which is the
expanding macro you referred to. The latter is useful for event tables
only. As you confirmed EVT_MOUSE_EVENTS cannot be used in Bind or Connect.

Sorry, rereading it now it does seem rather unclear, but my "There is" was
in reply to your "is there a reason" question.

Yes, this is correct. And there is nothing we can do about it.
OTOH I never understood the point of having EVT_MOUSE_EVENTS neither, it
doesn't look useful to me to handle all mouse events in the same way. And
just looking at the code in e.g. wxGenericListCtrl doing it like this
should be a convincing enough argument for not using it.
