Detailed Description

Geometric class.

Library: xviews or winviews or mviews (mutually exclusive)

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
xThe x floating point coordinate.
yThe 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
pThe 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
newXThe x floating point coordinate.
newYThe 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
newXThe 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
newYThe 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
dxThe x delta offset.
dyThe y delta offset.
