## Usage

### Integration

<Tabs>
  <Tab title="CallButtonDemo.tsx">
    ```tsx theme={null}
    import { CometChat } from "@cometchat/chat-sdk-javascript";
    import { CometChatCallButtons } from "@cometchat/chat-uikit-react";
    import React from "react";

    const CallButtonDemo = () => {
      const [chatUser, setChatUser] = React.useState<CometChat.User>();
      React.useEffect(() => {
        CometChat.getUser("uid").then((user) => {
          setChatUser(user);
        });
      }, []);
      return <CometChatCallButtons user={chatUser} />;
    };

    export default CallButtonDemo;
    ```
  </Tab>

  <Tab title="App.tsx">
    ```tsx theme={null}
    import { CallButtonDemo } from "./CallButtonDemo";

    export default function App() {
      return (
        <div className="App">
          <div>
            <CallButtonDemo />
          </div>
        </div>
      );
    }
    ```
  </Tab>
</Tabs>

### Actions

[Actions](/ui-kit/react/components-overview#actions) dictate how a component functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the component to fit your specific needs.

##### 1. onError

This action doesn't change the behavior of the component but rather listens for any errors that occur in the Call Button component.

  <Tab title="TypeScript">
    ```ts theme={null}
    import { CometChat } from "@cometchat/chat-sdk-javascript";
    import { CometChatCallButtons } from "@cometchat/chat-uikit-react";

    const CallButtonDemo = () => {
      const [chatUser, setChatUser] = React.useState<CometChat.User>();
      React.useEffect(() => {
        CometChat.getUser("uid").then((user) => {
          setChatUser(user);
        });
      }, []);

      const handleOnError = (error: CometChat.CometChatException) => {
        console.log("Your Custom on error actions", error);
      };

      return <CometChatCallButtons user={chatUser} onError={handleOnError} />;
    };

    export default CallButtonDemo;

### Events

[Events](/ui-kit/react/components-overview#events) are emitted by a `Component`. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed.

The list of events emitted by the `Call Buttons` component is as follows.

| Event              | Description                                                                                               |
| ------------------ | --------------------------------------------------------------------------------------------------------- |
| **ccCallRejected** | This event is triggered when the initiated call is rejected by the receiver.                              |
| **ccCallEnded**    | This event is triggered when the initiated call successfully ends.                                        |
| **ccOutgoingCall** | This event is triggered when the user initiates a voice/video call.                                       |
| **ccMessageSent**  | This event is triggered when the sent message is in transit and also when it is received by the receiver. |
