Hi Jasper, Thanks for reply.
Here is my use case. Suppose we have a client called "father", who has a larger surface called "father surface" and a client called "child", whose smaller surface is "child surface". The child surface should be displayed in a given relative position above father surface and maintain their relative position. When I move father surface, the child surface will be moved together. But the child surface cannot be moved. Thus the child surface will looks like a part of father surface. I just need it works in the simplest scenario. I assume the two surfaces is in the same workspace, both surfaces cannot be resized, maximized or fullscreened. The two clients and compositor should work together to achieve this goal. I know this is a weird use case. I am just wondering if there is some natural or easy way to implement this functionality. Or I have to do a lot of modifications.
