When an X window appears, it has a chance to request a particular geometry (size and shape on the screen). There are lots of good reasons for this to happen. Some apps have a "-geometry" argument on the command line, some detect the shape of the screen and try to show up in the center of the screen (or the center of one of the screens, if their developers are Xinerama-savvy), some request the same geometry as when they were closed the last time, and so on. I assume WorkspaceByPos detects which screen an app "wants to go to" by where the requested geometry would put it.
That's absolutely correct and a much better explanation than my "where it wants to go to". :-)
With these use cases in mind, it seems useful, and perhaps even a nice feature.
I'm not entirely happy about WorkspaceByPos in its current version:
The way which WorkspaceByPos detects windows that do not have a requested geometry is by checking for the request for position 0,0. This seems to work fine, but I wonder if there is another, more 'proper' way to figure this out.
You should be looking at the Gravity of the window to determine this, if not already doing so. -- Thomas Adam
