I'm not sure what you mean. If there is a QImage, then it has an image, and you can call QImage::save(). The cache itself is maintained by QNetworkAccessManager and QNetworkDiskCache. If it is cached, then you could ask for it by URL and would get the cached version. If not, then it has to go get it again anyway...
I'm not sure I understood you though. ________________________________ From: T C <[email protected]> To: [email protected] Sent: Thu, January 13, 2011 3:23:13 PM Subject: [Qt-qml] Can you access the Image element's cached QImage/QPixmap from C++ code? Say your QML gui has a section with an Image element whose source points to some internet image (http://somwhere/myphoto.jpg for example). When the Image item is instantiated the default image provider retrieves it (in the background maybe) and then it is painted when ready. The QImage is then cached somewhere by the image provider using the source url as the key. Later on I would like my C++ code to be able to save this image to permanent storage, if the user chooses to do so. Is there a way to do this by directly accessing the cached QImage? I understand that I can write a custom image provider and plug that in to the QML app context, but I really don't want to redo all the stuff that loads remote images in background threads if I don't have to. Is there an easier way?
