Detailed Description

a normalized 2d int rectangle. 4 2d points. Same order and basic element sizing as _WIN32 RECT and MFC CRect

Constructor & Destructor Documentation

cRectI() [1/2]

GrayLib::cRectI::cRectI ( )

inlinenoexcept

cRectI() [2/2]

GrayLib::cRectI::cRectI ( DVALUE_t  nleft, DVALUE_t  ntop, DVALUE_t  nright = 0, DVALUE_t  nbottom = 0  )

Member Function Documentation

ClampPtInRectI()

bool GrayLib::cRectI::ClampPtInRectI ( cPoint2f &  pt ) const

inline

This is slightly weird because integer rectangles are not normally inclusive

ClampPtInRectX()

bool GrayLib::cRectI::ClampPtInRectX ( cPoint2i &  pt ) const

inlinenoexcept

get_RectSize()

cWinSize GrayLib::cRectI::get_RectSize ( ) const

inlinenoexcept

get_RectStr()

cString GrayLib::cRectI::get_RectStr

(

void

)

const

GetOverlapX()

DVALUE_t GrayLib::cRectI::GetOverlapX ( const cRectI &  rect ) const

inlinenoexcept

GetOverlapY()

DVALUE_t GrayLib::cRectI::GetOverlapY ( const cRectI &  rect ) const

inlinenoexcept

GetRectCorner()

cPoint2i GrayLib::cRectI::GetRectCorner

(

DIR_TYPE

eDir

)

const

Get the point if a directional corner of the cRectI.

IsInsideMe()

bool GrayLib::cRectI::IsInsideMe ( const cRectI &  rect ) const

inlinenoexcept

Is &rect inside this ? equal=inside ASSUME: Normalized rect

IsInsideX()

bool GrayLib::cRectI::IsInsideX ( DVALUE_t  x ) const

inlinenoexcept

non-inclusive of right. ASSUME normalized!

IsInsideY()

bool GrayLib::cRectI::IsInsideY ( DVALUE_t  y ) const

inlinenoexcept

non-inclusive of bottom. ASSUME normalized!

IsOverlapped() [1/2]

bool GrayLib::cRectI::IsOverlapped ( const cRectI &  r, DVALUE_t  minx, DVALUE_t  miny  ) const

inlinenoexcept

are the 2 rectangles overlapped by at least this amount?

IsOverlapped() [2/2]

bool GrayLib::cRectI::IsOverlapped ( const cRectI &  rect ) const

inlinenoexcept

are the 2 rectangles overlapped at all? NON inclusive rectangle. ASSUME: Normalized rectangle

OffsetPositive()

void GrayLib::cRectI::OffsetPositive ( )

inline

PtInRect() [1/2]

bool GrayLib::cRectI::PtInRect ( const cPoint2i &  pt ) const

inlinenoexcept

same as MFC PtInRect() NON inclusive rect! Is the point in the rectangle ? A point is within CRect if it lies on the left or top side or is within all four sides. A point on the right or bottom side is outside CRect.

Note

The rectangle must be normalized or this function may fail. You can call NormalizeRect to normalize the rectangle before calling this function.

PtInRect() [2/2]

bool GrayLib::cRectI::PtInRect ( DVALUE_t  x, DVALUE_t  y  ) const

inlinenoexcept

NON inclusive rect! Is the point in the rectangle ?

SetRectStr()

ITERATE_t GrayLib::cRectI::SetRectStr	(	const GChar_t *	pszVal,
		bool	bSizes = false
	)

parse reading the rectangle. for use of char ??

SnapToGrid()

void GrayLib::cRectI::SnapToGrid ( DVALUE_t  iSizeXY )

inlinenoexcept

assume iSizeXY is a power of 2

UnionPoint()

void GrayLib::cRectI::UnionPoint ( DVALUE_t  x, DVALUE_t  y  )

inline

Inflate this rect to include this point. ASSUME this is a NON inclusive rect! ASSUME normalized!

v_GetRect()

void GrayLib::cRectI::v_GetRect

(

cVariant &

vVal

)

const

v_SetRect()

ITERATE_t GrayLib::cRectI::v_SetRect	(	const cVariant &	vVal,
		ITERATE_t	i = 0
	)
