## Detailed Description

Size representation.

Gdk::Graphene::Size represents a size composed of a width by a height.

Since gtkmm 4.12:

## Constructor & Destructor Documentation

## ◆ Size() [1/5]

Gdk::Graphene::Size::Size | ( |  | ) |

Constructs an invalid object.

E.g. for output arguments to methods. There is not much you can do with the object before it has been assigned a valid value.

## ◆ Size() [2/5]

Gdk::Graphene::Size::Size | ( | graphene_size_t * | castitem,
|  | bool | make_a_copy = `false`
| ) |  |
| explicit

## ◆ Size() [3/5]

Gdk::Graphene::Size::Size | ( | const Size & | src | ) |

## ◆ Size() [4/5]

Gdk::Graphene::Size::Size | ( | Size && | other | ) |
| noexcept

## ◆ ~Size()

Gdk::Graphene::Size::~Size | ( |  | ) |
| noexcept

## ◆ Size() [5/5]

Gdk::Graphene::Size::Size | ( | float | width,
|  | float | height
| ) |  |

## Member Function Documentation

## ◆ equal()

bool Gdk::Graphene::Size::equal | ( | const Size & | b | ) | const

Checks whether the two give graphene_size_t are equal.

Since gtkmm 4.12:

Parameters

  b | A graphene_size_t.

Returns
  `true` if the sizes are equal.

## ◆ get_height()

float Gdk::Graphene::Size::get_height | ( |  | ) | const

## ◆ get_width()

float Gdk::Graphene::Size::get_width | ( |  | ) | const

## ◆ gobj() [1/2]

graphene_size_t * Gdk::Graphene::Size::gobj | ( |  | ) |
| inline

## ◆ gobj() [2/2]

const graphene_size_t * Gdk::Graphene::Size::gobj | ( |  | ) | const
| inline

## ◆ gobj_copy()

graphene_size_t * Gdk::Graphene::Size::gobj_copy | ( |  | ) | const

Provides access to the underlying C instance. The caller is responsible for freeing it. Use when directly setting fields in structs.

## ◆ operator bool()

Gdk::Graphene::Size::operator bool | ( |  | ) | const
| explicit

Checks if this instance is valid.

It is valid if and only if it contains a value. For instance,

if (size)
do_something()
size
valarray< size_t > size() const

## ◆ operator=() [1/2]

Size & Gdk::Graphene::Size::operator= | ( | const Size & | src | ) |

## ◆ operator=() [2/2]

Size & Gdk::Graphene::Size::operator= | ( | Size && | other | ) |
| noexcept

## ◆ set_height()

void Gdk::Graphene::Size::set_height | ( | const float & | value | ) |

## ◆ set_width()

void Gdk::Graphene::Size::set_width | ( | const float & | value | ) |

## ◆ swap()

void Gdk::Graphene::Size::swap | ( | Size & | other | ) |
| noexcept

## Friends And Related Symbol Documentation

## ◆ swap()

void swap | ( | Size & | lhs,
|  | Size & | rhs
| ) |  |
| related

Parameters

  lhs | The left-hand side
  rhs | The right-hand side

## ◆ wrap()

Gdk::Graphene::Size wrap | ( | graphene_size_t * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
