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()

bool QQuickItemGrabResult::saveToFile(const QString &fileName) const

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