Detailed Description

Geometric class.

Library: display

The IlvFloatPoint class deals with floating point coordinate values. We call these "floating points".

IlvPoint, IlvDoublePoint.

Constructor & Destructor Documentation

IlvFloatPoint::IlvFloatPoint	(	IlFloat	x = (IlFloat)0,
		IlFloat	y = (IlFloat)0
	)

Constructor.

Initializes a new IlvFloatPoint with the indicated coordinates. point. Its parameters represent the x and y coordinates of the floating point.

Member Function Documentation

IlFloat IlvFloatPoint::getX

(

)

const

Gets the x floating point coordinate.

This member function returns the x coordinate of a floating point.

Returns

The x floating point coordinate.

IlFloat IlvFloatPoint::getY

(

)

const

Gets the y floating point coordinate.

This member function returns the y coordinate of a floating point.

Returns

The y floating point coordinate.

void IlvFloatPoint::move	(	IlFloat	x,
		IlFloat	y
	)

Moves the object.

Takes an existing IlvFloatPoint object and moves it to another position.

Parameters

x	The x floating point coordinate.
y	The y floating point coordinate.

int IlvFloatPoint::operator!=

(

const IlvFloatPoint &

p

)

const

Tests floating points for inequality.

Returns

0 if p is the same as the current object.

IlvFloatPoint& IlvFloatPoint::operator=

(

const IlvFloatPoint &

p

)

Copies a floating point.

Copies p to the current object.

Parameters

p	The source point.

int IlvFloatPoint::operator==

(

const IlvFloatPoint &

p

)

const

Tests floating points for equality.

Returns

0 if p is different from the current object.

void IlvFloatPoint::set	(	IlFloat	newX,
		IlFloat	newY
	)

Sets the floating point coordinates.

This member function sets the two coordinates of a floating point.

Parameters

newX	The x floating point coordinate.
newY	The y floating point coordinate.

void IlvFloatPoint::setX

(

IlFloat

newX

)

Sets the x floating point coordinate.

This member function sets the x coordinate of a floating point.

Parameters

newX	The x floating point coordinate.

void IlvFloatPoint::setY

(

IlFloat

newY

)

Sets the y floating point coordinate.

This member function sets the y coordinate of a floating point.

Parameters

newY	The y floating point coordinate.

void IlvFloatPoint::translate	(	IlFloat	dx,
		IlFloat	dy
	)

Moves the object by relative translation.

Shifts an existing point to another location by means of a delta-distance approach. That is, you indicate the dx and dy values that represent the distance between the current position of the point and the target future position.

Parameters

dx	The x delta offset.
dy	The y delta offset.
