Detailed Description

Class base.

Constructor & Destructor Documentation

efl::gfx::base::base ( ::efl::eo::parent_type  _p )

inlineexplicit

Constructs a new efl::gfx::base object.

Constructs a new efl::gfx::base object. If you want this object to be a child of another Eo object, use an efl::eo::parent expression, like the example.

Example:

efl::gfx::base my_base(efl::eo::parent = parent_object);

See also

base(Eo* eo)

efl::gfx::base::base ( Eo *  eo )

inlineexplicit

Eo Constructor.

Constructs the object from an Eo* pointer stealing its ownership.

Parameters

eo	The Eo object pointer.

efl::gfx::base::base ( std::nullptr_t  )

inlineexplicit

nullptr_t Constructor.

Constructs an empty (null) object.

Member Function Documentation

void efl::gfx::base::position_get	(	int *	x_,
		int *	y_
	)		const

Retrieves the position of the given Evas object.

Parameters

x	in
y	in

void efl::gfx::base::position_set	(	int	x_,
		int	y_
	)		const

Move the given Evas object to the given location inside its canvas' viewport.

Parameters

x	in
y	in

void efl::gfx::base::size_get	(	int *	w_,
		int *	h_
	)		const

Retrieves the (rectangular) size of the given Evas object.

Parameters

w	in
h	in

void efl::gfx::base::size_set	(	int	w_,
		int	h_
	)		const

Changes the size of the given Evas object.

Parameters

w	in
h	in

bool efl::gfx::base::color_part_get	(	::efl::eina::string_view	part_,
		int *	r_,
		int *	g_,
		int *	b_,
		int *	a_
	)		const

Retrieves a specific color of the given Evas object.

Retrieves a specific color's RGB component (and alpha channel) values, which range from 0 to 255. For the alpha channel, which defines the object's transparency level, 0 means totally transparent, while 255 means opaque. These color values are premultiplied by the alpha value.

The “main“ color being mapped to NULL.

Usually you’ll use this attribute for text and rectangle objects, where the “main” color is their unique one. If set for objects which themselves have colors, like the images one, those colors get modulated by this one.

Note

Use NULL pointers on the components you're not interested in: they'll be ignored by the function.

Parameters

r	The red component of the given color.
g	The green component of the given color.
b	The blue component of the given color.
a	The alpha component of the given color.

bool efl::gfx::base::color_part_set	(	::efl::eina::string_view	part_,
		int	r_,
		int	g_,
		int	b_,
		int	a_
	)		const

Sets a specifc color of the given Efl.Gfx.Base object to the given one.

See also

evas_object_color_get() (for an example)

Note

These color values are expected to be premultiplied by a.

Parameters

r	The red component of the given color.
g	The green component of the given color.
b	The blue component of the given color.
a	The alpha component of the given color.
