GB.CanRaise

Syntax

int GB.CanRaise ( void *object , int id )

Checks if an object handles a specific event.

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
