Detailed Description

Annotated text class.

Library: ilvatext

This subclass of IlvAccelerator is specialized for using accelerators in an IlvAnnoText. It defines a function prototype for the accelerator action and provides storage for this action. Generally, applications do not need to use this class. Instead, they use the IlvAnnoText::addAccelerator and IlvAnnoText::removeAccelerator member functions.

Constructor & Destructor Documentation

IlvATAccelerator::IlvATAccelerator	(	IlvATAction	action = 0,
		IlvEventType	type = (IlvEventType)0,
		IlUShort	data = 0,
		IlUShort	modifiers = 0,
		IlAny	userArg = 0,
		IlUShort	modifiersToIgnore = 0
	)

Constructor.

Calls the constructor of the superclass with the event description and sets the accelerator action to atAction.

Parameters

atAction	The accelerator action.
type	Specifies the type of event that triggers the action.
data	Specifies the event data.
modifiers	The mandatory event modifiers.
userArg	The user argument for the accelerator action.
modifiersToIgnore	The optional event modifiers.

Member Function Documentation

IlvATAction IlvATAccelerator::action

(

)

const

Returns the accelerator action.

Returns

The action associated with the accelerator.

virtual void IlvATAccelerator::activate ( IlvAnnoText *  atext, IlvEvent &  event  ) const

virtual

Calls the accelerator action.

Virtual function called when the annotated text atext has received an event fulfilling the conditions to trigger the accelerator. The default implementation is to call the action (if any) associated with the accelerator:

action()(atext, event, userArg());

See Also

IlvAccelerator::trigger.

Parameters

atext	The annotated text object.
event	The event.

void IlvATAccelerator::setAction	(	IlvATAction	f,
		IlAny	a
	)

Sets the accelerator action and the user argument.

Parameters

atAction	The accelerator action.
userArg	The user argument for the accelerator action.
