## Detailed Description

See also QQuickItem::grabToImage().

## Property Documentation

### `[read-only]` image : const QImage

This property holds the pixel results from a grab.

If the grab is not yet complete or if it failed, a null image is returned (`image.isNull()` will return `true`).

Access functions:

QImage | image() const

### `[read-only]` url : const QUrl

This property holds a URL which can be used in conjunction with URL based image consumers, such as the QtQuick::Image type.

The URL is valid until the QQuickItemGrabResult object is deleted.

The URL does not represent a valid file or location to read it from, it is primarily a key to access images through Qt Quick's image-based types.

Access functions:

QUrl | url() const

## Member Function Documentation

### `[signal]` void QQuickItemGrabResult::ready()

This signal is emitted when the grab has completed.

### `[invokable]` bool QQuickItemGrabResult::saveToFile(const QString &fileName) const

Saves the grab result as an image to fileName. Returns `true` if successful; otherwise returns `false`.

Note: In Qt versions prior to 5.9, this function is marked as non-`const`.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

### `[invokable, since 6.2]` bool QQuickItemGrabResult::saveToFile(const QUrl &filePath) const

Saves the grab result as an image to filePath, which must refer to a local file name with a supported image format extension. Returns `true` if successful; otherwise returns `false`.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

This function was introduced in Qt 6.2.
