This function should only be used when you don't know the type of the widget. If you know what kind of widget you are copying, you should use the copy function.

Returns

Copy of the widget

Reimplemented from tgui::Group.

copy()

static RadioButtonGroup::Ptr tgui::RadioButtonGroup::copy ( RadioButtonGroup::ConstPtr  group )

static

Makes a copy of another group.

Parameters

group

The other group

Returns

The new group

create()

static RadioButtonGroup::Ptr tgui::RadioButtonGroup::create ( )

static

Creates a new group.

Returns

The new group

draw()

void tgui::RadioButtonGroup::draw ( BackendRenderTargetBase &  target, RenderStates  states  ) const

overridevirtual

Draw the child widgets to the render target.

Parameters

states	Current render states

Reimplemented from tgui::Group.

getCheckedRadioButton()

RadioButton::Ptr tgui::RadioButtonGroup::getCheckedRadioButton

(

)

const

Returns the radio button that is currently checked.
