◆ getCollisionItems()

void SymbolLabelRenderer::getCollisionItems	(	const std::shared_ptr< RasterProjector > &	vp,
		std::vector< CollisionItem > &	collisionItems,
		std::vector< CollisionItem > &	alwaysVisibleItems
	)

overridevirtual

get a list of all items to be collision detected. This method must be thread-safe as it will be called from another thread than the main/gui thread.

Parameters

vp	Include items in this viewport.
collisionItems	(output) vector of CollisionItems
alwaysVisibleItems	(output) vector of items that should always be visible

Implements Maria::ICollisionItemCollection.

◆ initCollisionUpdate()

virtual void Maria::SymbolLabelRenderer::initCollisionUpdate ( )

inlineoverridevirtual

Initialize collision update. This will be run after a collision update has been deemed necessary, and before the actual update thread is starting. It can be used to update generation counters, dirty flags, etc. Will be run from main thread only.

Implements Maria::ICollisionItemCollection.

◆ needsCollisionUpdate()

virtual bool Maria::SymbolLabelRenderer::needsCollisionUpdate ( const RasterProjector & vp ) const

inlineoverridevirtual

Check if the collection has changed so that we need to recalculate the visibility. This can for example be if any new items have been added or removed, or if items have changed size or shape. Will be run from main thread only.

Parameters

vp	Only include items in this viewport.

Returns: True if an update is required, false if not.

Implements Maria::ICollisionItemCollection.

◆ priority()

virtual int Maria::SymbolLabelRenderer::priority ( ) const

inlineoverridevirtual

Priority of this collection relative to other collections to be collision checked in the same grid. Higher priorities are added first and more likely to be shown.

Returns: Integer priority number. Higher numbers mean higher priority.

Implements Maria::ICollisionItemCollection.

◆ updateVisibility()

void Maria::SymbolLabelRenderer::updateVisibility ( const std::vector< VisibilityItem > & items )

overridevirtual

Update the visibility of items according to the given list of collision items.

Parameters

items Items with visibility information.

Implements Maria::ICollisionItemCollection.
