特性文档编制

image : variant

This property holds the pixel results from a grab in the form of a QImage .

url : url

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

The URL is valid while there is a reference in QML or JavaScript to the ItemGrabResult or while the image the URL references is actively used.

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.
