Detailed Description

This class contains the implementation for the root component of Showcase.

Root component only assigns components into its slots (background, overlay, menu, main and content-viewer)

Constructor & Destructor Documentation

Showcase::RootInstance::RootInstance

(

ComponentPtr

component

)

Member Function Documentation

void Showcase::RootInstance::componentAddedToSlot ( const QByteArray &  slotName, std::shared_ptr< Component >  comp  )

overridevirtual

Called when another component is added to a slot of this component.

This is meant for overriding, default implementation does nothing

Parameters

slotName	name of the slot
comp	the added component

Reimplemented from Showcase::UIComponentInstance.

void Showcase::RootInstance::removeInstance ( )

overrideprotectedvirtual

Allows removing component instance when the component is removed.

Implementations must not call instanceDestroyed of the associated component

Reimplemented from Showcase::UIComponentInstance.
