Detailed Description

Extend VIEW_ITEM by possibility of grouping items into a single object.

VIEW_GROUP does not take over ownership of the held items. The main purpose of this class is to group items and draw them on a single layer (in particular the overlay).

◆ lodScaleForThreshold()

double VIEW_ITEM::lodScaleForThreshold	(	const KIGFX::VIEW *	aView,
		int	aWhatIu,
		int	aThresholdIu
	)

staticprotectedinherited

Get the scale at which aWhatIu would be drawn at the same size as aThresholdIu on screen.

This is useful when a level-of-detail is defined in terms of a threshold size (i.e. 'only draw X when it will be bigger than Y size on screen').

E.g. if aWhatIu is 1000 and aThresholdIu is 100, then the item will be the same size as the threshold at 0.1 scale. Returning that 0.1 as the LoD will hide the item when the scale is less than 0.1 - i.e. smaller than the threshold.

Because even at zoom 1.0, 1mm in KiCad may not be exactly 1mm on a physical screen, the threshold may not be exact in practice.

aLayer	is the layer which should be drawn.
aView	is the VIEW that should be used for drawing.

◆ ViewGetLayers()

◆ ViewGetLOD()

virtual double KIGFX::VIEW_ITEM::ViewGetLOD	(	int	aLayer,
		const VIEW *	aView
	)		const

inlinevirtualinherited

Return the level of detail (LOD) of the item.

A level of detail is the minimal VIEW scale that is sufficient for an item to be shown on a given layer.

Use LOD_HIDE and LOD_SHOW constants to hide or show the item unconditionally.

Use lodScaleForThreshold() to calculate the LOD scale for when the item passes a certain threshold size on screen.

Parameters

aLayer	is the current drawing layer.
aView	is a pointer to the VIEW device we are drawing on.

Returns: the level of detail. 0 always shows the item, because the actual zoom level (or VIEW scale) is always > 0
