Detailed Description

RadioButton is a specific type of two-states button that is similar to CheckBox.

Additionally, it can be used together with RadioButtonGroup to interact with other radio buttons.

Returns

A RadioButton instance pointer.

create() [2/2]

RadioButton * create ( std::string_view backGround, std::string_view cross, TextureResType texType = TextureResType::LOCAL )

static

Another factory method to create a RadioButton instance.

This method uses less resource to create a RadioButton.

Parameters

backGround	The background image name in std::string.
cross	The cross image name in std::string.
texType	The texture's resource type in Widget::TextureResType.

Returns

A RadioButton instance pointer

addEventListener()

void addEventListener

(

const ccRadioButtonCallback &

callback

)

Add a callback function which would be called when radio button is selected or unselected.

Parameters

callback

A std::function with type

ccRadioButtonCallback

getDescription()

std::string getDescription ( ) const

overridevirtual

Gets the description string.

It makes debugging easier.

Returns

A string @lua NA
