Call Buttons

Overview

The Call Button is a Component provides users with the ability to make calls, access call-related functionalities, and control call settings. Clicking this button typically triggers the call to be placed to the desired recipient.

Usage

Actions

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. onVoiceCallClick

onVoiceCallClick is triggered when you click the voice call button of the Call Buttons component. You can override this action using the following code snippet.

app.component.ts

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }
  public userObject!: CometChat.User;
  ngOnInit(): void {
    CometChat.getUser("uid").then((user: CometChat.User) => {
      this.userObject = user;
    });
  }
  public handleOnVoiceCallClick = (user: CometChat.User, group: CometChat.Group) => {
    console.log("your custom on voice call click actions");
  };
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

app.component.html

<div class="fullwidth">
<cometchat-call-buttons
*ngIf="userObject"
[user]="userObject"
[onVoiceCallClick]="handleOnVoiceCallClick"
></cometchat-call-buttons>
</div>

2. onVideoCallClick

onVideoCallClick is triggered when you click the video call button of the Call Buttons component. You can override this action using the following code snippet.

app.component.ts

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }
  public userObject!: CometChat.User;
  ngOnInit(): void {
    CometChat.getUser("uid").then((user: CometChat.User) => {
      this.userObject = user;
    });
  }
  public handleOnVideoCallClick = (user: CometChat.User, group: CometChat.Group) => {
    console.log("your custom on video call click actions");
  };
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

app.component.html

<div class="fullwidth">
<cometchat-call-buttons
*ngIf="userObject"
[user]="userObject"
[onVideoCallClick]="handleOnVideoCallClick"
></cometchat-call-buttons>
</div>

3. onError

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

app.component.ts

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }
  public userObject!: CometChat.User;
  ngOnInit(): void {
    CometChat.getUser("uid").then((user: CometChat.User) => {
      this.userObject = user;
    });
  }
  public handleOnError = (error: CometChat.CometChatException) => {
    console.log("your custom on error action", error);
  };
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

app.component.html

<div class="fullwidth">
<cometchat-call-buttons
*ngIf="userObject"
[user]="userObject"
[onError]="handleOnError"
></cometchat-call-buttons>
</div>

Filters

Filters allow you to customize the data displayed in a list within a Component. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using RequestBuilders of ChatSDK.

The Call Buttons component does not have any exposed filters.

---

Events

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.

---

TypeScript

import {CometChatCallEvents} from "@cometchat/chat-uikit-angular";

this.ccCallRejected = CometChatCallEvents.ccCallRejected.subscribe(
(call: CometChat.Call) => {
        // Your Code
  }   
);

this.ccOutgoingCall = CometChatCallEvents.ccOutgoingCall.subscribe(
(call: CometChat.Call) => {
        // Your Code
  }        
);

this.ccCallEnded = CometChatCallEvents.ccCallEnded.subscribe(
(call: CometChat.Call) => {
        // Your Code
  }      
);

this.ccMessageSent = CometChatCallEvents.ccMessageSent.subscribe(
() => {
        // Your Code
  }      
);

Customization

To fit your app's design requirements, you can customize the appearance of the Call Buttons component. We provide exposed methods that allow you to modify the experience and behavior according to your specific needs.

Style

Using Style you can customize the look and feel of the component in your app, These parameters typically control elements such as the color, size, shape, and fonts used within the component.

1. CallButtons Style

To customize the appearance, you can assign a CallButtonsStyle object to the Call Buttons component.

Example

In this example, we are employing the callButtonsStyle.

app.component.ts

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }
  public userObject!: CometChat.User;
  ngOnInit(): void {
    CometChat.getUser("uid").then((user: CometChat.User) => {
      this.userObject = user;
    });
  }
  callButtonsStyle = new CallButtonsStyle({
    background: "#e5c9f5",
    height: "50px",
    width: "400px",
    border: "1px solid #f8f5fa",
    buttonBackground: "#7735d4",
    buttonBorderRadius: "10px",
    videoCallIconTextColor: "#ffffff",
    voiceCallIconTextColor: "#ffffff",
    buttonPadding: "20px",
  });
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
