Incoming Call

Overview​

The Incoming call is a Component that serves as a visual representation when the user receives an incoming call, such as a voice call or video call, providing options to answer or decline the call.

Image

The Incoming Call is comprised of the following base components:

ComponentsDescription
cometchat-list-itemThis component’s view consists of avatar, status indicator , title, and subtitle. The fields are then mapped with the SDK’s user, group class.
cometchat-iconThis component displays an icon. It currently supports only svg icons
cometchat-labelThis component provides descriptive information about the associated UI element.
cometchat-buttonThis component represents a button with optional icon and text.
cometchat-avatarThis component component displays an image or user's avatar with fallback to the first two letters of the username

Usage​

Integration​

import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { CometChatIncomingCall } from "@cometchat/chat-uikit-angular";
import { AppComponent } from "./app.component";

@NgModule({
  imports: [BrowserModule, CometChatIncomingCall],
  declarations: [AppComponent],
  providers: [],
  bootstrap: [AppComponent],
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
})
export class AppModule {}

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. onAccept​

onAccept is triggered when you click the accept button of the Incoming Call component. You can override this action using the following code snippet.

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 handleOnAccept = (call: CometChat.Call) => {
    console.log("your custom on accept actions", call);
  };
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}
2. onDecline​

onDecline is triggered when you click the Decline button of the Incoming Call component. You can override this action using the following code snippet.

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 handleOnDecline = (call: CometChat.Call) => {
    console.log("your custom on decline action");
  };
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}
3. onError​

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

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 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 });
      }
    );
  }
}

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 Chat SDK.

The Incoming Call 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 Incoming Call component is as follows.

EventDescription
ccCallRejectedThis event is triggered when the initiated call is rejected by the receiver.
ccCallAcceptedThis event is triggered when the initiated call is accepted by the receiver.
ccCallEndedThis event is triggered when the initiated call successfully ends.

Adding CometChatCallEvents Listener's

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

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

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

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

Removing CometChatCallEvents Listener's

this.ccCallRejected.unsubscribe();
this.ccCallAccepted.unsubscribe();
this.ccCallEnded.unsubscribe();

Customization​

To fit your app's design requirements, you can customize the appearance of the Incoming Call 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. IncomingCall Style​

To customize the appearance, you can assign a IncomingCallStyle object to the Incoming Call component.

Example

In this example, we are employing the IncomingCallStyle.

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import { IncomingCallStyle } from '@cometchat/uikit-shared';
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" })
  }
  incomingCallStyle = new IncomingCallStyle({
    acceptButtonBackground: "#7b49de",
    acceptButtonTextColor: "#ffffff",
    background: "#8761d4",
    declineButtonBackground: "#4b08d1",
  });
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });

Functionality​

These are a set of small functional customizations that allow you to fine-tune the overall experience of the component. With these, you can change text, set custom icons, and toggle the visibility of UI elements.

Here is a code snippet demonstrating how you can customize the functionality of the Incoming Call component.

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" })
  }

  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}
