isEmpty()

bool SelectionBeaconOverlay::isEmpty ( ) const

Here is the caller graph for this function:

needsRepaint

void SelectionBeaconOverlay::needsRepaint ( )

signal

Emitted while the flash animates so the canvas repaints its overlay stage. Stops firing once the flash has finished.

Here is the caller graph for this function:

paint()

void SelectionBeaconOverlay::paint	(	QPainter &	p,
		const std::function< QPointF(const QPointF &)> &	toPixel,
		const QSize &	viewport
	)

Draws the beacon(s) in DEVICE pixels.

Parameters

toPixel	maps scene coords → device pixels (MapCanvas supplies the same lambda the profile overlays use).
viewport	used to skip anchors outside the visible extent.

Here is the caller graph for this function:

setAnchors()

void SelectionBeaconOverlay::setAnchors

(

const QVector< QPointF > &

sceneAnchors

)

Replaces the anchor set (scene coords) and restarts the flash. An empty set clears the overlay and stops the animation.

setColor()

void SelectionBeaconOverlay::setColor

(

const QColor &

c

)

Accent colour; defaults to the selection colour the caller passes.
