Detailed Description

IEventDispatcher implementation that forwards Events to registered IEventHandler implementations.

Member Function Documentation

AddEventHandler()

virtual void iText.Kernel.Events.EventDispatcher.AddEventHandler ( String  type, iText.Kernel.Events.IEventHandler  handler  )

inlinevirtual

Adds new event handler.

Parameters

type	a type of event to be handled
handler	event handler

Implements iText.Kernel.Events.IEventDispatcher.

DispatchEvent() [1/2]

virtual void iText.Kernel.Events.EventDispatcher.DispatchEvent ( Event @  event )

inlinevirtual

Dispatches an event.

Parameters

event

the Event to be dispatched

Implements iText.Kernel.Events.IEventDispatcher.

DispatchEvent() [2/2]

virtual void iText.Kernel.Events.EventDispatcher.DispatchEvent ( Event @  event, bool  delayed  )

inlinevirtual

Dispatches a delayed event.

Dispatches a delayed event. Sometimes event cannot be handled immediately because event handler has not been set yet. In this case event is placed into event ques of dispatcher and is waiting until handler is assigned.

Parameters

event	the Event to be dispatched
delayed	flag whether Event delayed or not

Implements iText.Kernel.Events.IEventDispatcher.

HasEventHandler()

virtual bool iText.Kernel.Events.EventDispatcher.HasEventHandler ( String  type )

inlinevirtual

Checks if event dispatcher as an event handler assigned for a certain event type.

Parameters

type	a type of the Event

Returns

true if event dispatcher as an event handler assigned for a certain event type

Implements iText.Kernel.Events.IEventDispatcher.

RemoveAllHandlers()

virtual void iText.Kernel.Events.EventDispatcher.RemoveAllHandlers ( )

inlinevirtual

Remove all event handlers.

Implements iText.Kernel.Events.IEventDispatcher.

RemoveEventHandler()

virtual void iText.Kernel.Events.EventDispatcher.RemoveEventHandler ( String  type, iText.Kernel.Events.IEventHandler  handler  )

inlinevirtual

Removes event handler.

Parameters

type	a type of the Event
handler	event handler IEventHandler

Implements iText.Kernel.Events.IEventDispatcher.
