Detailed Description

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, an empty image is returned.

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

Member Function Documentation

`[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.
