### Method

# Gtk Window set_deletable

#### Declaration [src]

    void
    gtk_window_set_deletable (
      GtkWindow* window,
      gboolean setting
    )

#### Description [src]

Sets whether the window should be deletable.

By default, windows have a close button in the window frame. Some window managers allow GTK to disable this button. If you set the deletable property to `FALSE` using this function, GTK will do its best to convince the window manager not to show a close button. Depending on the system, this function may not have any effect when called on a window that is already visible, so you should call it before calling `gtk_widget_show()`.

On Windows, this function always works, since there’s no window manager policy involved.

Sets property | `Gtk.Window:deletable`

#### Parameters

`setting`

  Type: `gboolean`

  `TRUE` to decorate the window as deletable.
