Is it possible/reasonable, in X version 10 or 11, to implement "memory windows", that is, windows which have an associated pixmap which is updated by graphical operations on the window (even the obscured areas) and which handle exposure events by raster-oping from that pixmap? Has anyone already done this? Rick

V11 will have rasterops to memory pixmaps. Ken

From: ken@cs.rochester.edu (Ken Yap) V11 will have rasterops to memory pixmaps. By "rasterop," do you mean all graphical functions, or just manipulating rectangular blocks? Can event handlers be set up such that a rasterop is done just before an area is obscured? What happens when you try to draw a line on an already obscured area of a window. I guess I don't understand how your reply answers the question that I was asking. Does it mean yes? no? maybe? Rick
