Detailed Description

A choice sprite widget.

A choice widget may be used to represent a checkbox or a radio button.

Constructor & Destructor Documentation

ChoiceSpriteWidget() [1/2]

gf::ChoiceSpriteWidget::ChoiceSpriteWidget	(	const Texture &	texture,
		const RectF &	emptyRect,
		const RectF &	chosenRect
	)

Constructor.

Parameters

texture	The texture used for the widget
emptyRect	The rectangle in the texture for the empty state
chosenRect	The rectangle in the texture for the chosen state

ChoiceSpriteWidget() [2/2]

gf::ChoiceSpriteWidget::ChoiceSpriteWidget	(	const Texture &	emptyTexture,
		const Texture &	chosenTexture
	)

Constructor.

Parameters

emptyTexture	The texture for the empty state

Member Function Documentation

contains()

bool gf::ChoiceSpriteWidget::contains ( Vector2f  coords )

overridevirtual

Check if the widget contains the coordinates.

Parameters

coords

The coordinates to check

Returns

True if the coordinates are inside the widget

Implements gf::Widget.

draw()

void gf::ChoiceSpriteWidget::draw ( RenderTarget &  target, const RenderStates &  states  )

overridevirtual

Draw the object to a render target.

This is a pure virtual function that has to be implemented by the derived class to define how the drawable should be drawn.

Parameters

target	Render target to draw to
states	Current render states

Implements gf::Drawable.

isChosen()

bool gf::ChoiceSpriteWidget::isChosen ( ) const

inlinenoexcept

Check if the widget is in the chosen state.

setChosen()

void gf::ChoiceSpriteWidget::setChosen

(

bool

chosen = true

)

Set the state of the widget.

Parameters

chosen

The new state of the widget

See also

isChosen()

setChosenSprite()

void gf::ChoiceSpriteWidget::setChosenSprite	(	const Texture &	texture,
		const RectF &	textureRect
	)

Set the sprite for the chosen state.

Parameters

texture	The texture used for the chosen state
textureRect	The rectangle in the texture used for the chosen state

See also

setEmptySprite()

setEmptySprite()

void gf::ChoiceSpriteWidget::setEmptySprite	(	const Texture &	texture,
		const RectF &	textureRect
	)

Set the sprite for the empty state.

Parameters

texture	The texture used for the empty state
textureRect	The rectangle in the texture used for the empty state

See also

setChosenSprite()
