Constructor & Destructor Documentation

mpFloatRect::mpFloatRect ( mpWindow & w )

Construct a new mpFloatRect using it's parent mpWindow to obtain the number of Y-scales to use.

This makes sure that the y-size always matches the parent mpWindow y-size

Parameters

w	parent mpWindow from which to obtain informations

void mpFloatRect::InitializeBoundingBox	(	double	px,
		double	py,
		size_t	yAxisID = `0`
	)

inline

Initialize bounding box with an initial point.

Parameters

px	x-coordinate
py	y-coordinate
yAxisID	the y-axis ID (default 0, the first y axis)

bool mpFloatRect::PointIsInside	(	double	px,
		double	py,
		size_t	yAxisID = `0`
	)		const

inline

Is point inside this bounding box?

Parameters

px	x-coordinate
py	y-coordinate
yAxisID	the y-axis ID (default 0, the first y axis)

void mpFloatRect::UpdateBoundingBoxToInclude	(	double	px,
		double	py,
		size_t	yAxisID = `0`
	)

inline

Update bounding box to include this point.

Parameters

px	x-coordinate
py	y-coordinate
yAxisID	the y-axis ID (default 0, the first y axis)
