# MetaWindow

#### Description [src]

    abstract class Meta.Window : GObject.Object
      implements Gio.Initable {
      /* No available fields */
    }

A display-agnostic abstraction for a window.

`MetaWindow` is the core abstraction in Mutter of a window. It has the properties you’d expect, such as a title, 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_window_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 `MetaWorkspace`s 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`.

If `window` is transient, call `func` with the window for which it’s transient, repeatedly until either we find a non-transient window, or `func` returns `FALSE`.
