Parameters

entryfield Entryfield object to apply key press to

Returns: Void

void MHEG5entryfieldDeactivate ( MHEG5Entryfield * entryfield )

Apply the deactivation behaviour of the entryfield class. As this class has no own deactivation behaviour this function just invokes the deactivation behaviour from the base class.

Parameters
