look at the source code and you can see that Context is passed
Group:
static childContextTypes = {
radioGroup: PropTypes.any,
};
getChildContext() {
return {
radioGroup: {
onChange: this.onRadioChange,//this.props.onChange
},
};
}Radio:
static contextTypes = {
radioGroup: PropTypes.any,
};
render(){
//onChange
radioProps.onChange = this.context.radioGroup.onChange;
}take a look at the source code of antd, and set context, in Radio.Group
