[Qt-interest] Memory mapped image files

[Andreas Unger]

Hello all,

I have a device with limited RAM and my application, whose background image
changes many times in its lifetime, crashes often. It usually crashes when I
change the background image ten or more times consecutively. I'm trying to
figure out how I can resolve this problem. Right now I have a method that
receives a QString corresponding to the path of the image, and updates the
stylesheet of the main application window, which is a QGraphicsView. Does
anyone have some example code that shows how I can use a memory mapped image
file to set the background image for a QGraphicsView/QMainWindow? Will that
help?

Cheers,
Andreas
