Detailed Description

Geometric class.

Library: xviews or winviews or mviews (mutually exclusive)
The IlvPoint class is used to create a point.

IlvDeltaPoint, IlvFloatPoint, IlvDoublePoint.

Accessors

Accessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods IlvValueInterface::queryValue(), IlvValueInterface::queryValues(), IlvValueInterface::changeValue(), IlvValueInterface::changeValues(). This class defines the following accessors:

Data accessors

Name	Type	Equivalent methods
x	Int	x(), setX()
y	Int	y(), setY()

Method accessors

Name	Return type	Equivalent methods
IlvPoint(Int x, Int y)	IlvPoint	See [Constructor note] below.

[Constructor note]: using this accessor allows to create an instance of IlvPoint from a script. For example :

mypoint = new IlvPoint(100, 200);

This is equivalent to the following C++ code :

new IlvPoint(100, 200);

Constructor & Destructor Documentation

IlvPoint()

IlvPoint::IlvPoint	(	IlvPos	x = 0,
		IlvPos	y = 0
	)

Constructor.

Initializes a point with defined coordinates.

Parameters

x	The x coordinate of the new point.
y	The y coordinate of the new point.

Member Function Documentation

getX()

IlvPos IlvPoint::getX

(

)

const

Retrieves the current x coordinate.

Returns

The current x coordinate of this object.

getY()

IlvPos IlvPoint::getY

(

)

const

Retrieves the current y coordinate.

Returns

The current y coordinate of this object.

move()

void IlvPoint::move	(	IlvPos	x,
		IlvPos	y
	)

Sets the new position.

Parameters

x	The new x coordinate of this object.
y	The new y coordinate of this object.

operator!=()

int IlvPoint::operator!=

(

const IlvPoint &

p

)

const

Inequality operator.

Parameters

p	The point to compare to.

Returns

1 if p is different than the current object.

operator=()

IlvPoint& IlvPoint::operator=

(

const IlvPoint &

p

)

Assignment operator.

Parameters

p	The point that is copied to the current object.

operator==()

int IlvPoint::operator==

(

const IlvPoint &

p

)

const

Equality operator.

Parameters

p	The point to compare to.

Returns

0 if p is different than the current object.

set()

void IlvPoint::set	(	IlvPos	x,
		IlvPos	y
	)

Sets the new position.

Parameters

x	The new x coordinate of this object.
y	The new y coordinate of this object.

setX()

void IlvPoint::setX

(

IlvPos

newX

)

Sets the x coordinate.

Parameters

newX	The new x coordinate of this object.

setY()

void IlvPoint::setY

(

IlvPos

yy

)

Sets the y coordinate.

Parameters

yy	The new y coordinate of this object.

translate() [1/2]

void IlvPoint::translate	(	IlvPos	dx,
		IlvPos	dy
	)

Translates to a new position.

Shifts an existing point to another location by means of a vector. You indicate the x and y translation values that represent the distance between the current position of the point and the target future position.

Parameters

dx	The x translation to be applied to the object.
dy	The y translation to be applied to the object.

translate() [2/2]

void IlvPoint::translate

(

const IlvPoint &

delta

)

Translates to a new position.

Shifts an existing point to another location by means of a vector. You indicate the x and y translation values that represent the distance between the current position of the point and the target future position.

Parameters

delta

The translation vector that is applied.

x() [1/2]

IlvPos IlvPoint::x

(

)

const

Retrieves the current x coordinate.

Returns

The current x coordinate of this object.

x() [2/2]

void IlvPoint::x

(

IlvPos

newX

)

Sets the x coordinate.

Parameters

newX	The new x coordinate of this object.

y() [1/2]

IlvPos IlvPoint::y

(

)

const

Retrieves the current y coordinate.

Returns

The current y coordinate of this object.

y() [2/2]

void IlvPoint::y

(

IlvPos

newY

)

Sets the y coordinate.

Parameters

newY	The new y coordinate of this object.
