This patch implements a popup stack. When the first popup is opened the grab is started, and it is added to a list. Further popups will be added to this list but the grab won't change. When a popup is closed it is removed from the list and, if it is now empty, the grab is ended. A click outside the client area will send the popup_done event to all the popups in the list, and the grab will end.
Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for buiding weston and its dependencies.
