DevExtreme jQuery - 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, { static: false }) colorBox: DxColorBoxComponent
    // Prior to Angular 8
    // @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
    ],
    // ...
})
