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:

  • 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:

  • url() const

void QQuickItemGrabResult::ready()

This signal is emitted when the grab has completed.

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

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

[since 6.2] bool QQuickItemGrabResult::saveToFile(const QUrl &filePath) const

Saves the grab result as an image to filePath, which must refer to a local file name with a supported image format extension. Returns true if successful; otherwise returns false.

This function was introduced in Qt 6.2.
