Dear All expert,
I am confused with event register function. For example , for example event 'Hotspot' only need code
'Set handler....' to register, then it will be triggerred.But for event 'data changed' , It is need call method 'REGISTER_EDIT_EVENT'.
addtional to registerred.
Is there any regulaion for the event register ? Or only case by case ?
Thanks for your reply in advance !
