I posted the following message on the newsgroup and didn’t get any response and was hoping that I could get some help from you guys.
I have an application that has been ported from Unix (SGI & HP) to Windows (NT & 2000). In the OpenGL/X environment we relied on the backing store capability to handle the window repair and I’ve been trying to locate the equivalent functionality in MS Windows. I have searched this newsgroup with deja.com and couldn’t find anything.
The reason for using the backing store is that we often have a large amount of dynamic data which can be slow to repaint when the screen needs updating because of dialog windows coming up & down.
If there isn’t a replacement for the backing store, what other methods could be used to resolve this problem without doing a full redraw? I have considered keeping the back buffer in-sync with the front buffer and using this update the display when necessary. Since I haven’t tested this method out yet, is this a reasonable approach or is there a better method?
Thanks in advance for any help you might provide.
