VuoRendererItem Class Reference

Description

Subclass of QGraphicsItem, which can show bounding rects for debugging.

Public Types
enum	activityState { notTrackingActivity = -1, activityInProgress = 0 }
	Special composition component activity states. More...

Static Public Member Functions
static void	setSnapToGrid (bool snap)
	Specifies whether graphics items should be snapped to a grid.
static void	setDrawBoundingRects (bool drawBoundingRects)
	Specifies whether bounding rects will be shown the next time the QGraphicsScene is rendered.
static void	drawRect (QPainter *painter, QRectF rect)
	Draws a rect, for debugging.
static bool	getSnapToGrid ()
	Retrieves the boolean indicating whether graphics items should be snapped to a grid.

Protected Member Functions
void	drawBoundingRect (QPainter *painter)
	Draws this item's bounding rect, for debugging.
bool	getRenderActivity () const
	Retrieves the composition-wide boolean indicating whether recent activity (e.g., a node execution or event firing) by this item should be reflected in its rendering.
bool	getRenderHiddenCables () const
	Retrieves the composition-wide boolean indicating whether hidden ("wireless") cables should be rendered as if they were not hidden.
QGraphicsItem::CacheMode	getCurrentDefaultCacheMode () const
	Returns the current default cache mode for components of this composition.

Static Protected Member Functions
static void	addRoundedCorner (QPainterPath &path, bool drawLine, QPointF sharpCornerPoint, qreal radius, bool isTop, bool isLeft)
	Appends a line (or move) and curve to path, to produce a clockwise-wound rounded corner near sharpCornerPoint.
