Dear all, we are currently using a QPixmap as a rendering cache for painting. I.e. paint once to a QPixmap, cache it and paint the QPixmap when required instead of performing the actual paint operations. In addition to the cached images we paint some elements directly.
We have currently some issues with high-resolution displays and UI scaling by the OS. Well, probably we can sort this out. However in that context, the following question arose: What is the correct caching strategy for painting? Caching the data as QImage, QPixmap or QPicture? Additionally, are there any examples how to correctly implement this with high-resolution displays / UI scaling by the OS? Thanks in advance, Tim _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
