Detailed Description

Component instance class for components that create operators.

Member Function Documentation

MultiWidgets::OperatorPtr Showcase::OperatorInstance::operatorInstance ( MultiWidgets::Widget &  host, bool  immediate = false  )

overridevirtual

Assigns the operator to the given widget.

ComponentInstance erases the last strong pointer to the operator after this If immediate is set to true, operator is added to the widget during this call, otherwise it's added to the widget in main thread after next update.

Reimplemented from Showcase::ComponentInstance.

void Showcase::OperatorInstance::propertyLost ( const PropertyKey &  key, const PropertyValue &  value  )

overridevirtual

Called when a property is unset for the component This function may be called same time from multiple threads.

Parameters

key	identifies the target property
value	value for the property

Reimplemented from Showcase::ComponentInstance.

void Showcase::OperatorInstance::propertyReceived ( const PropertyKey &  key, const PropertyValue &  value  )

overridevirtual

Called for each property found for the creator component This function may be called same time from multiple threads.

Parameters

key	identifies the target property
value	new value set for the property

Reimplemented from Showcase::ComponentInstance.

void Showcase::OperatorInstance::removeInstance ( )

overridevirtual

Allows removing component instance when the component is removed.

Implementations must not call instanceDestroyed of the associated component

Reimplemented from Showcase::UIComponentInstance.
