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 |
