Member Function Documentation

AddEventHandler()

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

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

Parameters delayed

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

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, IEventHandler  handler  )

inlinevirtual

Removes event handler.

Parameters

type	Parameters handler

Implements iText.Kernel.Events.IEventDispatcher.
