VuoRendererCable Class Reference

Description

Renders a cable in a VuoRendererGraph.

Public Member Functions
	VuoRendererCable (VuoCable *baseCable)
	Creates a renderer detail for the specified baseCable.
QRectF	boundingRect (void) const
	Returns a rectangle containing the rendered cable (including thick cable width).
QPainterPath	shape (void) const
	Returns the shape of the rendered cable, for use in collision detection, hit tests, and QGraphicsScene::items() functions.
void	paint (QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget)
	Draws the cable on painter.
void	setPenToHighlightSelection (QPen *pen)
	Customizes the pen to function as a highlighter to indicate that the cable is currently selected.
void	setPenToHighlightDisconnectionPotential (QPen *pen)
	Customizes the pen to function as a highlighter to indicate that the cable would be disconnected if dragged from the cursor's current location.
void	setFloatingEndpointLoc (QPointF loc)
	Sets the coordinates of the cable's floating endpoint.
void	removeFromScene ()
	Removes a cable from the canvas and performs other necessary cleanup.
void	highlightEligiblePorts (void)
	Highlights all ports eligible to be connected to the unattached end of this cable.
void	extendedHoverEnterEvent (QPointF scenePos)
	Handle mouse hover start events generated by custom code making use of an extended hover range.
void	extendedHoverMoveEvent (QPointF scenePos)
	Handle mouse hover move events generated by custom code making use of an extended hover range.
void	extendedHoverLeaveEvent (QPointF scenePos)
	Handle mouse hover leave events generated by custom code making use of an extended hover range.
VuoPort *	getFloatingEndpointPreviousToPort ()
	Returns the cable's previous 'To' port (if the cable has since been disconnected from that port by dragging), or NULL if not applicable.
void	setFloatingEndpointPreviousToPort (VuoPort *port)
	Sets the cable's previous 'To' port (if the cable has since been disconnected from that port by dragging), or NULL if not applicable.
void	setEligibleForDisconnection (bool eligible)
	Sets the boolean indicating that the cable would be disconnected if dragged from the cursor's current location.
void	updateGeometry (void)
	Schedules a redraw of this cable.
Public Member Functions inherited from VuoBaseDetail< VuoCable >
	VuoBaseDetail (string id, VuoCable *base)
	Creates a VuoCable detail class.
VuoCable *	getBase (void) const
	Returns the VuoCable detail class instance's base class instance.
void	setBase (VuoCable *base)
	Sets the VuoCable detail class instance's base class instance.

Protected Member Functions
void	mousePressEvent (QGraphicsSceneMouseEvent *event)
	Re-implements QGraphicsItem::mousePressEvent(QGraphicsSceneMouseEvent *event) to address bug https://bugreports.qt-project.org/browse/QTBUG-3306, which causes non-movable graphics items to be deselected upon right-click.
Protected Member Functions inherited from VuoRendererItem
void	drawBoundingRect (QPainter *painter)
	Draws this item's bounding rect, for debugging.

Additional Inherited Members
Static Public Member Functions inherited from VuoRendererItem
static void	setDrawBoundingRects (bool drawBoundingRects)
	Specifies whether bounding rects will be shown the next time the QGraphicsScene is rendered.
