DevExtreme Vue - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
← → ↑ ↓ | Moves the color pointer. |
Ctrl + ↑ | Moves the RGB slider up. |
Ctrl + ↓ | Moves the RGB slider down. |
Ctrl + ← | Moves the transparency slider left. |
Ctrl + → | Moves the transparency slider right. |
Enter | Selects the color. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
jQuery
JavaScript
function registerKeyHandlers () { let colorBox = $("#colorBoxContainer").dxColorBox("instance"); colorBox.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); colorBox.registerKeyHandler("space", function (e) { // ... }); }
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from "@angular/core"; import { DxColorBoxModule, DxColorBoxComponent } from "devextreme-angular"; // ... export class AppComponent implements AfterViewInit { @ViewChild(DxColorBoxComponent) colorBox: DxColorBoxComponent ngAfterViewInit () { this.colorBox.instance.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); this.colorBox.instance.registerKeyHandler("space", function (e) { // ... }); } } @NgModule({ imports: [ // ... DxColorBoxModule ], // ... })
