  GTK_WIN_POS_MOUSE,
  GTK_WIN_POS_CENTER_ALWAYS,
  GTK_WIN_POS_CENTER_ON_PARENT
} GtkWindowPosition;

Window placement can be influenced using this enumeration. Note that using GTK_WIN_POS_CENTER_ALWAYS is almost always a bad idea. It won't necessarily work well with all window managers or on all windowing systems.

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.

enum GtkSortType

typedef enum
{
  GTK_SORT_ASCENDING,
  GTK_SORT_DESCENDING
} GtkSortType;

Determines the direction of a sort.

enum GtkDragResult

typedef enum

  GTK_DRAG_RESULT_TIMEOUT_EXPIRED,
  GTK_DRAG_RESULT_GRAB_BROKEN,
  GTK_DRAG_RESULT_ERROR
} GtkDragResult;

Gives an indication why a drag operation failed. The value can by obtained by connecting to the "drag-failed" signal.
