             Bug #: 45595
           Summary: mouse wrapping doesn't work when the window is
                    partially outside of the physical screen
    Classification: Unclassified
           Product: Spice
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: gtk-client
        AssignedTo: spice-bugs at lists.freedesktop.org
        ReportedBy: alevy at redhat.com


If the window of spice-gtk is partially outside of the physical screen, like
so:

                                  .----------------------.
                                  |   physical screen    |
                            .-----------------.          |
                            |    spice-gtk    |          |
                            |     widget      |          |
                            |                 |          |
                            |                 |          |
                            |                 |          |
                            |                 |          |
                            '-----------------'          |
                                  |                      |
                                  '----------------------'

This doesn't work for linux and for windows.

For linux, the problem is that the grab area is wrongly set to:

                                  .----------------------.
                                  |                      |
                            .---------------.            |
                            |.-------------.|            |
                            ||  grab area  ||            |
                            ||             ||            |
                            ||             ||            |
                            |'-------------'|            |
                            '---------------'            |
                                  |                      |
                                  |                      |
                                  '----------------------'

and we actually want it to be the whole screen.

For windows we can use WH_MOUSE_LL for SetWindowsHookEx

But there is an even better implementation that we need to copy from spicec.
