Angular TileView - Keyboard Support
An end user can use the following keys to interact with the UI component.
Key | Action |
---|---|
Shift + Mouse Wheel | Scrolls the content left/right if the direction property is "horizontal". |
←→↑↓ | Moves focus to the neighboring tile. |
Home | Moves focus to the very first tile. |
End | Moves focus to the very last tile. |
Enter or Space | Selects the focused tile. |
Use the registerKeyHandler(key, handler) method to implement a custom handler for a key.
jQuery
JavaScript
function registerKeyHandlers () { const tileView = $("#tileViewContainer").dxTileView("instance"); tileView.registerKeyHandler("backspace", function(e) { // The argument "e" contains information on the event }); tileView.registerKeyHandler("space", function(e) { // ... }); }
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from '@angular/core'; import { DxTileViewModule, DxTileViewComponent } from 'devextreme-angular'; // ... export class AppComponent implements AfterViewInit { @ViewChild(DxTileViewComponent, { static: false }) tileView: DxTileViewComponent; // Prior to Angular 8 // @ViewChild(DxTileViewComponent) tileView: DxTileViewComponent; ngAfterViewInit () { this.tileView.instance.registerKeyHandler('backspace', function(e) { // The argument "e" contains information on the event }); this.tileView.instance.registerKeyHandler('space', function(e) { // ... }); } } @NgModule({ imports: [ // ... DxTileViewModule ], // ... })
Vue
<template> <DxTileView :ref="myTileViewRef" /> </template> <script> import 'devextreme/dist/css/dx.light.css'; import DxTileView from 'devextreme-vue/tile-view'; const myTileViewRef = 'my-tile-view'; export default { components: { DxTileView }, data() { return { myTileViewRef } }, computed: { tileView: function() { return this.$refs[myTileViewRef].instance; } }, mounted: function() { this.tileView.registerKeyHandler('backspace', function(e) { // The argument "e" contains information on the event }); this.tileView.registerKeyHandler('space', function(e) { // ... }); } } </script>
React
App.js
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { TileView } from 'devextreme-react/tile-view'; class App extends React.Component { constructor(props) { super(props); this.tileViewRef = React.createRef(); } render() { return ( <TileView ref={this.tileViewRef} /> ); } get tileView() { return this.tileViewRef.current.instance(); } componentDidMount() { this.tileView.registerKeyHandler('backspace', function(e) { // The argument "e" contains information on the event }); this.tileView.registerKeyHandler('space', function(e) { // ... }); } } export default App;
