Detailed Description

A KisBaseNode is the base class for all components of an image: nodes, layers masks, selections. A node has a number of properties, can be represented as a thumbnail and knows what to do when it gets a certain paint device to process. A KisBaseNode does not know anything about its peers. You should not directly inherit from a KisBaseNode; inherit from KisNode instead.

Constructor & Destructor Documentation

◆ KisBaseNode() [1/2]

KisBaseNode::KisBaseNode ( KisImageWSP image )

Create a new, empty base node. The node is unnamed, unlocked visible and unlinked.

Be cautious! These two calls are vital to warm-up KoProperties. We use it and its QMap in a threaded environment. This is not officially supported by Qt, but our environment guarantees, that there will be the only writer and several readers. Whilst the value of the QMap is boolean and there are no implicit-sharing calls provocated, it is safe to work with it in such an environment.

Member Function Documentation

◆ accept() [1/2]

virtual bool KisBaseNode::accept ( KisNodeVisitor & )

inlinevirtual

Accept the KisNodeVisitor (for the Visitor design pattern), should call the correct function on the KisNodeVisitor for this node type, so you need to override it for all leaf classes in the node inheritance hierarchy.

return false if the visitor could not successfully act on this node instance.

Reimplemented in KisGeneratorLayer, KisAdjustmentLayer, KisCloneLayer, KisShapeLayer, KisReferenceImagesLayer, KisFileLayer, KisDecorationsWrapperLayer, KisFilterMask, KisGroupLayer, KisNode, KisPaintLayer, KisSelectionMask, KisTransformMask, KisTransparencyMask, and KisColorizeMask.

    }

◆ accept() [2/2]

virtual void KisBaseNode::accept	(	KisProcessingVisitor &	visitor,
		KisUndoAdapter *	undoAdapter )

inlinevirtual

Accept the KisNodeVisitor (for the Visitor design pattern), should call the correct function on the KisProcessingVisitor for this node type, so you need to override it for all leaf classes in the node inheritance hierarchy.

The processing visitor differs from node visitor in the way that it accepts undo adapter, that allows the processing to be multithreaded

◆ sectionModelProperties()

KisBaseNode::PropertyList KisBaseNode::sectionModelProperties ( ) const

virtual

Return a the properties of this base node (locked, visible etc, with the right icons for their representation and their state.

Subclasses can extend this list with new properties, like opacity for layers or visualized for masks.

The order of properties is, unfortunately, for now, important, so take care which properties superclasses of your class define.

KisBaseNode defines visible = 0, locked = 1 KisLayer defines opacity = 2, compositeOp = 3 KisMask defines active = 2 (KisMask does not inherit kislayer)

◆ setVisible()

void KisBaseNode::setVisible	(	bool	visible,
		bool	loading = false )

virtual

Set the visible status of this node. Visible nodes are active in the graph (except for selections masks which can be active while hidden), that is to say, they are taken into account when merging. Invisible nodes play no role in the final image , but will be modified when modifying all layers, for instance when cropping.

Toggling the visibility of a node will not automatically lead to recomposition.

Parameters

visible	the new visibility state
isLoading	if true, the property is set during loading.

◆ supportsKeyframeChannel()

bool KisBaseNode::supportsKeyframeChannel ( const QString & id )

virtual

Ideally, this function would be used to query for keyframe support before trying to create channels. The ability to query would help in cases such as animation curves where you might want to ask which channels it supports before allowing the user to add.

Returns: bool whether it supports said channel or not.
