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  )

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.

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()

operator=() [1/2]

Size & Gdk::Graphene::Size::operator=

operator=() [2/2]

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

noexcept

set_height()

set_width()

void Gdk::Graphene::Size::set_width

(

const float &

swap()

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

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.
