Constructor & Destructor Documentation

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

Creates a collapsed "Make List" node, which takes the form of an input drawer.

void

)

const

Returns the vector of the input ports whose values will be incorporated into the output list.

VuoRendererPort * VuoRendererMakeListNode::getHostInputPort

(

void

)

const

Returns the input port to which this collapsed "Make List" node is attached.

qreal VuoRendererMakeListNode::getMaxDrawerChainedLabelWidth

(

void

)

const

Returns the maximum width in pixels of the port labels within this drawer, also accounting for the width of the child port as well as any constant flags or collapsed typecasts attached to the child port.

qreal VuoRendererMakeListNode::getMaxDrawerLabelWidth

(

void

)

const

Returns the maximum width in pixels of the port labels within this drawer.

QRectF VuoRendererMakeListNode::getNodeTitleBoundingRect ( void  ) const

virtual

Returns the bounding rect for the node title box.

Since MakeList nodes don't display their titles, return the entire node boundingRect instead.

Reimplemented from VuoRendererNode.

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

virtual

Draws a collapsed "Make List" node.

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.

Reimplemented from VuoRendererNode.

void VuoRendererMakeListNode::setDragInProgress

(

bool

inProgress

)

Sets the boolean indicating whether this node's drag handle is currently being dragged.

void VuoRendererMakeListNode::setHorizontalDrawerOffset

(

qreal

offset

)

Sets the distance, in pixels, left of its attached port that the rightmost point of this drawer should be rendered.

QPainterPath VuoRendererMakeListNode::shape

(

)

const

Returns the shape of the rendered "Make List" node, for use in collision detection, hit tests, and QGraphicsScene::items() functions.

Member Data Documentation

const qreal VuoRendererMakeListNode::drawerHorizontalSpacing = VuoRendererFonts::thickPenWidth*1./4.

static

The amount of space, in pixels, left as horizontal padding between underhangs of drawers attached to ports of the same node.
