Hi Scuri,
I tested IupUser and indeed, setting POSTMESSAGE_CB does respond to
IupPostMessage. However, IupUser does NOT return POSTMESSAGE_CB when I call
IupGetClassCallbacks("user", ...). I understand IupUser is meant to be a
foundation and perhaps that is why it doesn't return POSTMESSAGE_CB as a
supported callback. Would it make sense to add at least register the
POSTMESSAGE_CB callback to it however?
Also, I noticed the class metadata for POSTMESSAGE_CB elsewhere omits the
callback argument information. e.g. for IupButton, the class metadata its
POSTMESSAGE_CB, callback is empty where I think it should instead be "sidV"
(string, int, double, pointer). Would it make sense to register POSTMESSAGE_CB
with those parameter types rather than returning nothing?
Thanks,
Matt
