View Full Version : QGraphicScene to stream
phannent

Hello,
I have an application which has a QList of QGraphicsScene's, I would like to save the scenes to a file and restore them. Can anybody show some example code of how I would do that?
Do I have to iterate through each item in the scene and send it to a QDataStream? or can I just do something like:
QDataStream out;
out << m_scenes;
Regards
Phil

See http://doc.trolltech.com/4.4/datastreamformat.html for the complete list of all Qt types supporting data streaming.
Then you have to write code to serialize GraphicsItem and scene data
