Class TSize

class TSize;

Description

Stores a two-dimensional size as a width and a height value.

Its data members are public and can be manipulated directly, or by means of the functions provided.

inline TSize(TUninitialized);

Description

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

Parameters

inline TSize();

Description

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

inline TSize(TInt aWidth, TInt aHeight);

Description

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

Parameters

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

Description

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

Return value

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

Description

Compares two TSize for inequality.

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

Parameters

Return value

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

Description

TSize subtraction assignment operator.

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

Parameters

Return value

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

Description

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

Return value

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

Description

TSize addition assignment operator.

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

Parameters

Return value

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

Description

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

Return value

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

Description

TSize subtraction operator.

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

Parameters

Return value

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

Description

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

Return value

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

Description

TSize addition operator.

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

Parameters

Return value

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

Description

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

Return value

IMPORT_C TSize operator-() const;

Description

Unary minus operator.

The operator returns the negation of this TSize.

Return value

IMPORT_C void SetSize(TInt aWidth, TInt aHeight);

Description

Sets the width and height.

Parameters

IMPORT_C TPoint AsPoint() const;

Description

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

Return value

TUninitialized

Description

TInt iWidth;

Description

The width of this TSize object.

TInt iHeight;

Description

The height of this TSize object.
