Constructor & Destructor Documentation

TSize(TUninitialized)

TSize ( TUninitialized ) [inline]

Constructs the size object with its iWidth and iHeight members set to zero.

Parameters

TUninitialized

TSize()

TSize ( ) [inline]

Constructs the size object with its iWidth and iHeight members set to zero.

TSize(TInt, TInt)

TSize ( TInt aWidth,
TInt aHeight
) [inline]

Constructs the size object with the specified width and height values.

Parameters

TInt aWidth The width value.
TInt aHeight The height value .

Member Functions Documentation

AsPoint()

IMPORT_C TPoint AsPoint ( ) const

Gets a TPoint object whose co-ordinates are the width and height of this TSize .

SetSize(TInt, TInt)

IMPORT_C void SetSize ( TInt aWidth,
TInt aHeight
)

Sets the width and height.

Parameters

TInt aWidth The width value.
TInt aHeight The height value.

operator!=(const TSize &)

IMPORT_C TBool operator!= ( const TSize & aSize ) const

Compares two TSize for inequality.

For two TSize to be unequal, either their width or height values must be different.

Parameters

const TSize & aSize The TSize to be compared with this TSize.

operator+(const TSize &)

IMPORT_C TSize operator+ ( const TSize & aSize ) const

TSize addition operator.

This operator adds the specified TSize to this TSize , and returns the resulting value.

Parameters

const TSize & aSize The TSize to be added to this Tsize.

operator+(const TPoint &)

IMPORT_C TSize operator+ ( const TPoint & aPoint ) const

TPoint addition operator.

This operator adds the specified point to this TSize , and returns the resulting value.

The operation proceeds by:

1. adding the x co-ordinate value to the width

2. adding the y co-ordinate value to the height

Parameters

const TPoint & aPoint The point to be added to this TSize.

operator+=(const TSize &)

IMPORT_C TSize & operator+= ( const TSize & aSize )

TSize addition assignment operator.

The operator adds the specified TSize to this TSize , and assigns the result back to this TSize .

Parameters

const TSize & aSize The TSize to be added.

operator+=(const TPoint &)

IMPORT_C TSize & operator+= ( const TPoint & aPoint )

TPoint addition assignment operator.

The operator adds the specified point to this TSize , and assigns the result back to this TSize .

The operation proceeds by:

1. adding the point's x co-ordinate value to the width

2. adding the point's y co-ordinate value to the height.

Parameters

const TPoint & aPoint The point to be added.

operator-(const TSize &)

IMPORT_C TSize operator- ( const TSize & aSize ) const

TSize subtraction operator.

This operator subtracts the specified TSize from this TSize , and returns the resulting value.

Parameters

const TSize & aSize The TSize to be subtracted from this Tsize.

operator-(const TPoint &)

IMPORT_C TSize operator- ( const TPoint & aPoint ) const

TPoint subtraction operator.

This operator subtracts the specified point from this TSize , and returns the resulting value.

The operation proceeds by:

1. subtracting the x co-ordinate value from the width

2. subtracting the y co-ordinate value from the height

Parameters

const TPoint & aPoint The point to be subtracted.

operator-()

IMPORT_C TSize operator- ( ) const

Unary minus operator.

The operator returns the negation of this TSize .

operator-=(const TSize &)

IMPORT_C TSize & operator-= ( const TSize & aSize )

TSize subtraction assignment operator.

The operator subtracts the specified TSize from this TSize , and assigns the result back to this TSize .

Parameters

const TSize & aSize The TSize to be subtracted.

operator-=(const TPoint &)

IMPORT_C TSize & operator-= ( const TPoint & aPoint )

TPoint subtraction assignment operator.

The operator subtracts the specified point from this TSize , and assigns the result back to this TSize .

The operation proceeds by:

1. subtracting the point's x co-ordinate value from the width

2. subtracting the point's y co-ordinate value from the height.

Parameters

const TPoint & aPoint The point to be subtracted.

operator==(const TSize &)

IMPORT_C TBool operator== ( const TSize & aSize ) const

Compares this TSize with the specified TSize for equality.

For two TSizes to be equal, both their width and height values must be equal.

Parameters

const TSize & aSize The TSize to be compared with this TSize.
