Detailed Description

A representation of dependency between different canvas resources stored in KoResourceManager.

A resource dependency looks like that

source ----->----- depends on ----->----- target

, that is, when 'target' changes 'source' should be updated.

Member Function Documentation

◆ shouldUpdateSource()

virtual bool KoActiveCanvasResourceDependency::shouldUpdateSource	(	QVariant &	source,
		const QVariant &	target )

pure virtual

Returns: true if source does really depend on target and the manager should Q_EMIT notification about target's change

Implemented in KoActiveCanvasResourceDependencyKoResource< ResourceType >.

◆ sourceKey()

int KoActiveCanvasResourceDependency::sourceKey ( ) const

Returns: the resource type that should be updated when targetKey() is changed

Definition at line 29 of file KoActiveCanvasResourceDependency.cpp.

{
    return m_d->sourceKey;
}

References m_d.

◆ targetKey()

int KoActiveCanvasResourceDependency::targetKey ( ) const

Returns: the resource type that should cause updates sourceKey()

Definition at line 34 of file KoActiveCanvasResourceDependency.cpp.

{
    return m_d->targetKey;
}
