Property Documentation
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 |
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 |

[signal] void QQuickItemGrabResult::ready()
This signal is emitted when the grab has completed.
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.
