GB.CanRaise
int GB.CanRaise ( void *object , int id )
Checks if an object handles a specific event.
-
object is the object that raises the event.
-
id is the event identifier, as got with the
GB_EVENT macro.
This function returns
TRUE if the class of the object object has an event handler for the
specified event, and returns 0 otherwise.
You will use this function to avoid raising useless events, as sometimes calling
GB.Raise
needs some heavy calculation.
But calling this function is not mandatory, as it implicitely called anyway by
GB.Raise
