The layers are ordered, and each of the surfaces in one layer are * above all of the surfaces in the layer below. The set of layers is static and * in the following order (top-most first): * • Lock layer (only ever displayed on its own) * • Cursor layer * • Input panel layer * • Fullscreen layer * • Panel layer * • Workspace layers * • Background layer * * The list of layers may be manipulated to remove whole layers of surfaces from * display. For example, when locking the screen, all layers except the lock * layer are removed. * * A surface’s layer is modified on configuring the surface, in * set_surface_type() (which is only called when the surface’s type change is * _committed_). If a surface’s type changes (e.g. when making a window * fullscreen) its layer changes too. * * In order to allow popup and transient surfaces to be correctly stacked above * their parent surfaces, each surface tracks both its parent surface, and a * linked list of its children. When a surface’s layer is updated, so are the * layers of its children. Note that child surfaces are *not* the same as * subsurfaces — child/parent surfaces are purely for maintaining stacking * order. * * The children_link list of siblings of a surface (i.e. those surfaces which * have the same parent) only contains weston_surfaces which have a * shell_surface. Stacking is not implemented for non-shell_surface * weston_surfaces. This means that the following implication does *not* hold: * (shsurf->parent != NULL) ⇒ !wl_list_is_empty(shsurf->children_link) */ struct shell_surface { struct wl_signal destroy_signal; struct weston_desktop_surface *desktop_surface;
