Detailed Description

template<class T>
class Vector2< T >

Use Vec2i for integer and Vec2d or Vec2f typedef for vectors of double and float respectively.

Constructor & Destructor Documentation

Vector2() [1/2]

template<class T>

Vector2< T >::Vector2 ( const T *  x )

inlineexplicit

Warning

Does not check array size, make sure it has at least 2 elements

Vector2() [2/2]

template<class T >

template<class T2 >

Vector2< T >::Vector2 ( const Vector2< T2 > &  other )

inlineexplicit

Uses default primitive type conversion

Member Function Documentation

operator=()

template<class T>

Vector2< T > & Vector2< T >::operator= ( const T *  a )

inline

Warning

Does not check array size, make sure it has at least 2 elements

toStr()

template<class T>

QString Vector2< T >::toStr

(

)

const

The result can be restored into a Vector2 by the Vector2(QString s) constructors.
