ConfirmDialog is built on top of Modal
and displays a confirmation dialog, with confirm and cancel buttons.

The dialog is confirmed by clicking the confirm button or by pressing the Enter key.
It is cancelled (closed) by clicking the cancel button, by pressing the ESC key, or by
clicking outside the dialog focus (i.e. the overlay).

ConfirmDialog has two main modes: controlled and uncontrolled.

Uncontrolled mode

Allows the component to be used standalone, just by declaring it as part of another React
component’s render method:

• It will be automatically open (displayed) upon mounting.
• It will be automatically closed when clicking the cancel button, by pressing the ESC
  key, or by clicking outside the dialog focus (i.e. the overlay).
• onCancel is not mandatory but can be passed. Even if passed, the dialog will still be
  able to close itself.

Activating this mode is as simple as omitting the isOpen prop. The only mandatory prop
in this case is the onConfirm callback. The message is passed as the children.

import { __experimentalConfirmDialog as ConfirmDialog } from '@wordpress/components';

function Example() {
    return (
        <ConfirmDialog onConfirm={ () => console.debug( 'Confirmed!' ) }>
            Are you sure? <strong>This action cannot be undone!</strong>
        </ConfirmDialog>
    );
}

Controlled mode

Let the parent component control when the dialog is open/closed. It’s activated when a
boolean value is passed to isOpen:

• It will not be automatically closed. You need to let it know when to open/close by
  updating the value of the isOpen prop.
• Both onConfirm and the onCancel callbacks are mandatory props in this mode.
• You’ll want to update the state that controls isOpen from the onCancel and
  onConfirm callbacks.

import { useState } from '@wordpress/element';
import { __experimentalConfirmDialog as ConfirmDialog } from '@wordpress/components';

function Example() {
    const [ isOpen, setIsOpen ] = useState( true );

    const handleConfirm = () => {
        console.debug( 'Confirmed!' );
        setIsOpen( false );
    };

    const handleCancel = () => {
        console.debug( 'Cancelled!' );
        setIsOpen( false );
    };

    return (
        <ConfirmDialog
            isOpen={ isOpen }
            onConfirm={ handleConfirm }
            onCancel={ handleCancel }
        >
            Are you sure? <strong>This action cannot be undone!</strong>
        </ConfirmDialog>
    );
}

Props

__experimentalHideHeader

• Type: boolean
• Required: No
• Default: true

Whether the underlying Modal should hide its header, title included.

children

• Type: ReactNode
• Required: Yes

The actual message for the dialog. It’s passed as children and any valid ReactNode is accepted.

confirmButtonText

• Type: string
• Required: No

The optional custom text to display as the confirmation button’s label.

cancelButtonText

• Type: string
• Required: No

The optional custom text to display as the cancellation button’s label.

isOpen

• Type: boolean
• Required: No

Defines if the dialog is open (displayed) or closed (not rendered/displayed).
It also implicitly toggles the controlled mode if set or the uncontrolled mode if it’s not set.

isBusy

• Type: boolean
• Required: No

Indicates activity while an action is being performed.
When true, the confirm button will show a busy state.
Both buttons will be disabled.

onConfirm

• Type: (event: DialogInputEvent) => void
• Required: Yes

The callback that’s called when the user confirms.
A confirmation can happen when the OK button is clicked or when Enter is pressed.

onCancel

• Type: ((event: DialogInputEvent) => void)
• Required: No

The callback that’s called when the user cancels. A cancellation can happen
when the Cancel button is clicked, when the ESC key is pressed, or when
a click outside of the dialog focus is detected (i.e. in the overlay).

It’s not required if isOpen is not set (uncontrolled mode), as the component
will take care of closing itself, but you can still pass a callback if something
must be done upon cancelling (the component will still close itself in this case).

If isOpen is set (controlled mode), then it’s required, and you need to set
the state that defines isOpen to false as part of this callback if you want the
dialog to close when the user cancels.

size

• Type: "small" | "fill" | "medium" | "large"
• Required: No

Size of the underlying Modal. See Modal‘s size prop.

title

• Type: string
• Required: No

The title of the underlying Modal: its accessible name, and the
visible heading unless __experimentalHideHeader is true.
