Patch to treat frame offsets as signed (637 bytes, patch)

Description Matt Hodges 2004-02-09 15:22:47 UTC 
[Debian package/Version: 1:1.3+cvs20031104-4]

I tried (setq warp-to-window-enabled t), and when the cursor warps, it
ends up at the very top left point of the workspace (I'm not using
viewports).

I had a look at the code, and the problem seems to be with
window-frame-offset values:

    user> (mapcar (lambda (w) (window-frame-offset w)) (managed-windows))
    ((0 . 0)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806)
     (0 . 0)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806)
     (0 . 0)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806)
     (1073741823 . 1073741806))

The values returned by window-position and window-dimensions are OK.

Note that I don't see this problem on i386.

Patch to treat frame offsets as signed

The problem is that sawfish is treating the frame offsets as unsigned but they
now seem to be signed. This patch corrects that.

I've tested that on v1.3.3 and that does not happen anymore.
