Description

Renders a node in a VuoRendererGraph.

Public Types
enum	Type { node, detachedConstant, detachedDrawer, detachedTypecast }
	Specifies how this node is graphically represented.

Public Member Functions
	VuoRendererNode (VuoNode baseNode, VuoRendererSignaler signaler)
	Creates a renderer detail for the specified base node.

QRectF	boundingRect (void) const
	Returns a rectangle that completely encloses the rendered node (accounting for the thick line width).

void	paint (QPainter painter, const QStyleOptionGraphicsItem option, QWidget *widget)
	Draws a standard node, including rectangular frame, and input and output ports.

void	highlight (QPainter *painter)
	Highlights the node.

QRectF	getNodeFrameRect (void) const
	Returns the horizontal offset necessary to prevent the drawer at `portIndex` from overlapping any drawers beneath it.

void	setPortConnected (VuoRendererPort *rendererPort, bool isOutputPort, bool isConnected, bool hasData=false)
	Changes the portConnected value for the specified port on this node.

void	setProxyNode (VuoRendererNode *proxyNode)
	If set, this node will not be drawn; its drawing will be handled by `proxyNode`.

VuoRendererNode *	getProxyNode (void) const
	Returns this node's rendering proxy.

QVariant	itemChange (GraphicsItemChange change, const QVariant &value)
	Updates the node and its connected cables to reflect changes in position.

void	updateGeometry (void)
	Schedules a redraw of this node.

void	updateConnectedCableGeometry (void)

VuoRendererPortList *	getInputPorts (void)
	Returns this node's input ports, as a `VuoRendererPortList`.

VuoRendererPortList *	getOutputPorts (void)
	Returns this node's output ports, as a `VuoRendererPortList`.

void	replaceInputPort (VuoRendererPort oldPort, VuoRendererPort newPort)
	Replaces input port `old` with `new`.

void	addInputPort (VuoRendererPort *newPort)
	Adds input port `port` to the node.

Public Member Functions inherited from VuoBaseDetail< VuoNode >
	VuoBaseDetail (string id, VuoNode *base)
	Creates a VuoNode detail class.

VuoNode *	getBase (void) const
	Returns the VuoNode detail class instance's base class instance.

void	setBase (VuoNode *base)
	Sets the VuoNode detail class instance's base class instance.

Static Public Attributes
static const qreal	thickPenWidth = 20
	Width, in pixels at 1:1 zoom, of the top and bottom node edges. Many other drawing metrics are based on this value.

static const qreal	midPenWidth = VuoRendererNode::thickPenWidth/10.0
	Width, in pixels at 1:1 zoom, of stateful indicator bars and typecast port edges.

static void	setDrawBoundingRects (bool drawBoundingRects)
	Specifies whether bounding rects will be shown the next time the QGraphicsScene is rendered.

Protected Member Functions inherited from VuoRendererItem
void	drawBoundingRect (QPainter *painter)
	Draws this item's bounding rect, for debugging.

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).

set< VuoCable * > VuoRendererNode::getConnectedCables ( void )

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 ( void )

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 ( void )

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

Returns the horizontal offset necessary to prevent the drawer at portIndex from overlapping any drawers beneath it.

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

Note that this returns the inner frame, not an outer bounding box (i.e., it doesn't include the width of thick lines).

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 use a QPainter transform 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::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.
