DevExtreme Angular - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
Tab | Moves focus to the next toolbar item. |
Shift + Tab | Moves focus to the previous toolbar item. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
jQuery
JavaScript
function registerKeyHandlers () { let toolbar = $("#toolbarContainer").dxToolbar("instance"); toolbar.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); toolbar.registerKeyHandler("space", function (e) { // ... }); }
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from "@angular/core"; import { DxToolbarModule, DxToolbarComponent } from "devextreme-angular"; // ... export class AppComponent implements AfterViewInit { @ViewChild(DxToolbarComponent) toolbar: DxToolbarComponent ngAfterViewInit () { this.toolbar.instance.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); this.toolbar.instance.registerKeyHandler("space", function (e) { // ... }); } } @NgModule({ imports: [ // ... DxToolbarModule ], // ... })
