Angular Popup - Keyboard Support

An end user can use the following keys to interact with the UI component.

Key Action
↑ → ↓ ← Drags the popup when it is focused and dragEnabled is true.
Esc Closes the popup.

You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.

App.js
  • import React from 'react';
  • import 'devextreme/dist/css/dx.light.css';
  •  
  • import { Popup } from 'devextreme-react/popup';
  •  
  • class App extends React.Component {
  • constructor(props) {
  • super(props);
  •  
  • this.popupRef = React.createRef();
  • }
  •  
  • render() {
  • return (
  • <Popup ref={this.popupRef} />
  • );
  • }
  •  
  • get popup() {
  • return this.popupRef.current.instance;
  • }
  •  
  • componentDidMount() {
  • this.popup.registerKeyHandler('backspace', function(e) {
  • // The argument "e" contains information on the event
  • });
  • this.popup.registerKeyHandler('space', function(e) {
  • // ...
  • });
  • }
  • }
  •  
  • export default App;
