Constructor & Destructor Documentation

VuoRendererNode::VuoRendererNode	(	VuoNode *	baseNode,
		VuoRendererSignaler *	signaler
	)

Creates a renderer detail for the specified base node.

Member Function Documentation

void VuoRendererNode::addInputPort ( VuoRendererPort * newPort )

Adds input port port to the node.

Affects only renderer detail ports (not base or compiler ports).

QString VuoRendererNode::generateNodeClassToolTip ( VuoNodeClass * nodeClass )

static

Generates a descriptive tooltip containing information about the input nodeClass.

set< VuoCable * > VuoRendererNode::getConnectedCables ( bool includePublishedCables )

Returns the set of cables connected to this node.

This includes:

Cables connected to any of the node's input ports.
Cables connected to the child port of any collapsed typecast attached to an input port.
Cables connected to any of the node's output ports.

set< VuoCable * > VuoRendererNode::getConnectedInputCables ( bool includePublishedCables )

Returns the set of input cables connected to this node.

This includes:

Cables connected to any of the node's input ports.
Cables connected to the child port of any collapsed typecast attached to an input port.

set< VuoCable * > VuoRendererNode::getConnectedOutputCables ( bool includePublishedCables )

Returns the set of output cables connected to this node.

This includes:

Cables connected to any of the node's output ports.

VuoRendererPortList * VuoRendererNode::getInputPorts ( void )

Returns this node's input ports, as a VuoRendererPortList.

See Also: VuoNode::getInputPorts()

QRectF VuoRendererNode::getNodeFrameRect ( void ) const

Determines and returns the size of the inner frame of a node having the specified attributes.

The "inner frame" is the light grey rect in the middle of the node. It doesn't include the node's header or footer.

VuoRendererPortList * VuoRendererNode::getOutputPorts ( void )

Returns this node's output ports, as a VuoRendererPortList.

See Also: VuoNode::getInputPorts()

void VuoRendererNode::paint	(	QPainter *	painter,
		const QStyleOptionGraphicsItem *	option,
		QWidget *	widget
	)

Draws a standard node, including rectangular frame, and input and output ports.

The node is drawn with (0,0) as the top left inner margin, so you should use a QPainter transform if you want to position the node.

void VuoRendererNode::replaceInputPort	(	VuoRendererPort *	oldPort,
		VuoRendererPort *	newPort
	)

Replaces input port old with new.

Affects only renderer detail ports (not base or compiler ports).

void VuoRendererNode::setCollapsedForm ( VuoRendererPort * collapsedForm )

Sets the collapsed form associated (currently or ever in the past) with this node.

This form will be re-used if the node is uncollapsed and subsequently recollapsed. Useful for, e.g., attached typecast nodes.

void VuoRendererNode::setProxyNode ( VuoRendererNode * proxyNode )

If set, this node will not be drawn; its drawing will be handled by proxyNode.

Useful for, e.g., attached typecast nodes.
