How to use the radiobutton function from blessed

blessed.radiobutton is a widget in the Blessed library that creates a radio button element.

How does blessed.radiobutton work?

blessed.radiobutton works by creating a radio button element that can be added to a Blessed screen or element.

The radio button can be created with a label and a unique ID, which is used to identify the selected option.

When the radio button is selected, it emits a select event that can be used to update the state of the application or trigger some other action.

By using blessed.radiobutton, developers can easily create radio button elements in their Blessed applications and respond to user input.

const blessed = require("blessed");

const screen = blessed.screen();
screen.title = "My Radio Buttons";

const radio1 = blessed.radiobutton({
  parent: screen,
  mouse: true,
  keys: true,
  shrink: true,
  top: 2,
  left: 2,
  width: 15,
  height: 1,
  name: "radio1",
  content: "Option 1",
  value: 1,
});

const radio2 = blessed.radiobutton({
  parent: screen,
  mouse: true,
  keys: true,
  shrink: true,
  top: 4,
  left: 2,
  width: 15,
  height: 1,
  name: "radio2",
  content: "Option 2",
  value: 2,
});

const radio3 = blessed.radiobutton({
  parent: screen,
  mouse: true,
  keys: true,
  shrink: true,
  top: 6,
  left: 2,
  width: 15,
  height: 1,
  name: "radio3",
  content: "Option 3",
  value: 3,
});

screen.render();

radio1.on("select", () => {
  console.log(`Option 1 selected`);
});

radio2.on("select", () => {
  console.log(`Option 2 selected`);
});

radio3.on("select", () => {
  console.log(`Option 3 selected`);
});

In this example, we use blessed.radiobutton to create three radio buttons in a Blessed application. We first create a Blessed screen and define its title. We then create three blessed.radiobutton widgets, passing in various options such as the widget position, dimensions, label, and value. We add each radio button to the screen using its parent property, and call the render() method on the screen to display the widgets. We also add event listeners to each radio button that listen for the select event and log a message to the console when the button is selected. By using blessed.radiobutton in this way, we can easily create radio button elements in our Blessed applications and respond to user input.
