## Member Function Documentation

### `[slot]` void QWebEngineNotification::click() const

Creates and dispatches a JavaScript click event on notification.

Should be called by the notification platform when the notification is activated by the user.

### `[slot]` void QWebEngineNotification::close() const

Creates and dispatches a JavaScript close event on notification.

Should be called by the notification platform when the notification is closed, either by the underlying platform or by the user.

### `[signal]` void QWebEngineNotification::closed()

This signal is emitted when the web page calls close steps for the notification, and it no longer needs to be shown.

### QImage QWebEngineNotification::icon() const

Returns the icon to be shown with the notification.

If no icon is set by the sender, a null QImage is returned.

### bool QWebEngineNotification::matches(const QWebEngineNotification *other) const

Returns `true` if the two notifications belong to the same message chain. That is, if their tag() and origin() are the same. This means one is a replacement or an update of the other.

See also tag() and origin().

### `[slot]` void QWebEngineNotification::show() const

Creates and dispatches a JavaScript show event on notification.

Should be called by the notification platform when the notification has been shown to user.
