### enum GtkWindowPosition

    typedef enum
    {
      GTK_WIN_POS_NONE,

### enum GtkWindowType

    typedef enum
    {
      GTK_WINDOW_TOPLEVEL,
      GTK_WINDOW_POPUP
    } GtkWindowType;

A GtkWindow can be one of these types. Most things you'd consider a "window" should have type GTK_WINDOW_TOPLEVEL; windows with this type are managed by the window manager and have a frame by default (call gtk_window_set_decorated() to toggle the frame). Windows with type GTK_WINDOW_POPUP are ignored by the window manager; window manager keybindings won't work on them, the window manager won't decorate the window with a frame, many GTK+ features that rely on the window manager will not work (e.g. resize grips and maximization/minimization). GTK_WINDOW_POPUP is used to implement widgets such as GtkMenu or tooltips that you normally don't think of as windows per se. Nearly all windows should be GTK_WINDOW_TOPLEVEL. In particular, do not use GTK_WINDOW_POPUP just to turn off the window borders; use gtk_window_set_decorated() for that.

`GTK_WINDOW_TOPLEVEL` | A regular window, such as a dialog.
`GTK_WINDOW_POPUP` | A special window such as a tooltip.

### enum GtkSortType

    typedef enum
    {
      GTK_SORT_ASCENDING,
      GTK_SORT_DESCENDING

Determines the direction of a sort.

`GTK_SORT_ASCENDING` | Sorting is in ascending order.
`GTK_SORT_DESCENDING` | Sorting is in descending order.
