@jsvision/ui / ButtonActivation

Interface: ButtonActivation ​

Defined in: ui/src/controls/button.ts:45

Read-only activation metadata for a Button.

The descriptor intentionally reports whether a callback is bound without exposing the callback itself. Headless inspectors can therefore identify an action without invoking application code.

Example ​

ts
import { Button } from '@jsvision/ui';

const save = new Button('~S~ave', { command: 'file.save', onClick: () => console.log('saved') });
console.log(save.activation);
// { label: 'Save', command: 'file.save', hasCallback: true }

Properties ​

command ​

readonly command: string | null

Defined in: ui/src/controls/button.ts:49

Configured command, or null when activation is callback-only.

hasCallback ​

readonly hasCallback: boolean

Defined in: ui/src/controls/button.ts:51

Whether activation invokes an application callback in addition to any command.

label ​

readonly label: string

Defined in: ui/src/controls/button.ts:47

Visible label after accelerator markers have been removed.
