Detailed Description

event handler stored inside an InteractorComposite

This is meant to be focused on event handling only. An InteractorComponent should respond to user inputs in its eventFilter method and return true to avoid further propagation of the event to other components. This system is inherited from Qt event handling, see QObject::eventFilter() for details.

subclass of Interactor that allows building Interactors using component classes focused specifically on input handling.

The composite behaves like a regular interactor. Event handling is made using InteractorComponent subclasses. Basically, an InteractorComposite is a list of InteractorComponent. Each of them are meant to be pushed in the list using the push_back and push_front methods. When an event is caught by the InteractorComposite, it will iterate over all components (in th order provided by the list) and run eventFilter on each one of them until one of the component returns true.

When subclassing InteractorComposite, you should push your components in the construct() method (take care of the order they are pushed in). Once the setView() method is called (after construct()), the init() method will be run on every components.

Examples:

interactor_plugin/interactor_plugin.cpp.

Constructor & Destructor Documentation

tlp::InteractorComposite::InteractorComposite	(	const QIcon &	icon,
		const QString &	text = ""
	)

Default constructor.

Parameters

icon	The icon set on the interactor's action
text	The text set on the interactor's action

Member Function Documentation

virtual QAction* tlp::InteractorComposite::action ( ) const

virtual

Returns

a QAction associated to this interactor. This is used by the overleying system to associate an icon/text to the interactor.

Warning

The parent (QObject::parent()) object of this QAction MUST BE the Interactor.

Implements tlp::Interactor.

iterator tlp::InteractorComposite::begin

(

)

Since InteractorComposte behaves like a list of InteractorComponent, this method is here to allow this class to be iterable.

const_iterator tlp::InteractorComposite::begin

(

)

const

Since InteractorComposte behaves like a list of InteractorComponent, this method is here to allow this class to be iterable.

virtual QCursor tlp::InteractorComposite::cursor ( ) const

virtual

Returns

The cursor associated to this interactor. When the interactor gets active on a view, the View's cursor is changed to what this method returns.

Implements tlp::Interactor.

iterator tlp::InteractorComposite::end

(

)

Since InteractorComposte behaves like a list of InteractorComponent, this method is here to allow this class to be iterable.

const_iterator tlp::InteractorComposite::end

(

)

const

Since InteractorComposte behaves like a list of InteractorComponent, this method is here to allow this class to be iterable.

QObject* tlp::InteractorComposite::lastTarget ( ) const

protected

Returns

The last target the interactor was installed on.

Note

If the lastTarget is destroyed before uninstall was called, the lastTarget() method will return NULL.

void tlp::InteractorComposite::push_back

(

InteractorComponent *

component

)

Pushs an InteractorComponent at the end of the list.

void tlp::InteractorComposite::push_front

(

InteractorComponent *

component

)

Pushs an InteractorComponent at the beggining of the list.

void tlp::InteractorComposite::setLastTarget ( QObject *  )

protected

backup a QObject into the InteractorComposite. This can be used to store the last target the interactor was installed on. This can be used when uninstall is called.

virtual tlp::View* tlp::InteractorComposite::view ( ) const

virtual

Returns

the View object associated to this Interactor.

Warning

The returned object MUST be the same as the one passed down to the setView method.

Implements tlp::Interactor.
