It has the * properties you'd expect, such as a title, an icon, whether it's fullscreen, * has decorations, etc. * * Since a lot of different kinds of windows exist, each window also a * #MetaWindowType which denotes which kind of window we're exactly dealing * with. For example, one expects slightly different behaviour from a dialog * than a "normal" window. The type of a window can be queried with * meta_window_get_type(). * * Common API for windows include: * - Minimizing: meta_window_minimize() / meta_window_unminimize() * - Maximizing: meta_window_maximize() / meta_window_unmaximize() * - Fullscreen: meta_window_make_fullscreen() / meta_window_unmake_fullscreen() * / meta_window_is_fullscreen() * * Each #MetaWindow is part of either one or all #MetaWorkspaces of the * desktop. You can activate a window on a certain workspace using * meta_window_activate_with_workspace(), and query on which workspace it is * located using meta_window_located_on_workspace(). The workspace it is part * of can be obtained using meta_window_get_workspace(). * * Each display protocol should make a subclass to be compatible with that * protocols' specifics, for example #MetaWindowX11 and #MetaWindowWayland. * This is independent of the protocol that the client uses, which is modeled * using the #MetaWindowClientType enum. * * To integrate within the Clutter scene graph, which deals with the actual * rendering, each #MetaWindow will be part of a #MetaWindowActor. */ #include "config.h" #include "core/window-private.h" #include #include #include #include #include "backends/meta-backend-private.h" #include "backends/meta-logical-monitor.h" #include "cogl/cogl.h" #include "core/boxes-private.h" #include "core/constraints.h" #include "core/edge-resistance.h" #include "core/frame.h" #include "core/keybindings-private.h" #include "core/meta-workspace-manager-private.h" #include "core/place.h" #include "core/stack.h" #include "core/util-private.h" #include "core/workspace-private.h" #include "meta/compositor-mutter.h" #include "meta/group.h" #include "meta/meta-cursor-tracker.h" #include "meta/meta-enum-types.h" #include "meta/meta-x11-errors.h" #include "meta/prefs.h" #include "ui/ui.h" #include "x11/meta-x11-display-private.h" #include "x11/window-props.h" #include "x11/window-x11.h" #include "x11/xprops.h" #ifdef HAVE_WAYLAND #include "wayland/meta-wayland-private.h" #include "wayland/meta-wayland-surface.h" #include "wayland/meta-window-wayland.h" #include "wayland/meta-window-xwayland.h" #endif /* Windows that unmaximize to a size bigger than that fraction of the workarea * will be scaled down to that size (while maintaining aspect ratio). * Windows that cover an area greater then this size are automaximized on map. */ #define MAX_UNMAXIMIZED_WINDOW_AREA .8 #define SNAP_SECURITY_LABEL_PREFIX "snap." static int destroying_windows_disallowed = 0; /* Each window has a "stamp" which is a non-recycled 64-bit ID.
