    typedef enum
    {

      GTK_STATE_ACTIVE,
      GTK_STATE_PRELIGHT,
      GTK_STATE_SELECTED,
      GTK_STATE_INSENSITIVE
    } GtkStateType;

This type indicates the current state of a widget; the state determines how the widget is drawn. The GtkStateType enumeration is also used to identify different colors in a GtkStyle for drawing, so states can be used for subparts of a widget as well as entire widgets.

`GTK_STATE_NORMAL` | State during normal operation.
`GTK_STATE_ACTIVE` | State of a currently active widget, such as a depressed button.
`GTK_STATE_PRELIGHT` | State indicating that the mouse pointer is over the widget and the widget will respond to mouse clicks.

`GTK_STATE_INSENSITIVE` | State indicating that the widget is unresponsive to user actions.

### enum GtkSubmenuDirection

`GTK_DIRECTION_RIGHT` | A sub-menu will appear to the right of the current menu.

### enum GtkSubmenuPlacement

    typedef enum
    {
      GTK_TOP_BOTTOM,
      GTK_LEFT_RIGHT
    } GtkSubmenuPlacement;

### Warning

`GtkSubmenuPlacement` is deprecated and should not be used in newly-written code.

### enum GtkToolbarStyle

    typedef enum
    {
      GTK_TOOLBAR_ICONS,
      GTK_TOOLBAR_TEXT,
      GTK_TOOLBAR_BOTH,
      GTK_TOOLBAR_BOTH_HORIZ
    } GtkToolbarStyle;

Used to customize the appearance of a GtkToolbar. Note that setting the toolbar style overrides the user's preferences for the default toolbar style. Note that if the button has only a label set and GTK_TOOLBAR_ICONS is used, the label will be visible, and vice versa.

`GTK_TOOLBAR_ICONS` | Buttons display only icons in the toolbar.
`GTK_TOOLBAR_TEXT` | Buttons display only text labels in the toolbar.
`GTK_TOOLBAR_BOTH` | Buttons display text and icons in the toolbar.
`GTK_TOOLBAR_BOTH_HORIZ` | Buttons display icons and text alongside each other, rather than vertically stacked

### enum GtkUpdateType

    typedef enum

`GTK_UPDATE_DISCONTINUOUS` | Notify updates when the mouse button has been released
`GTK_UPDATE_DELAYED` | Space out updates with a small timeout

    typedef enum
    {
      GTK_VISIBILITY_NONE,
      GTK_VISIBILITY_PARTIAL,
      GTK_VISIBILITY_FULL
    } GtkVisibility;

Used by GtkCList and GtkCTree to indicate whether a row is visible.

`GTK_VISIBILITY_NONE` | The row is not visible.
`GTK_VISIBILITY_PARTIAL` | The row is partially visible.
`GTK_VISIBILITY_FULL` | The row is fully visible.

### enum GtkWindowPosition

    typedef enum
    {
      GTK_WIN_POS_NONE,
      GTK_WIN_POS_CENTER,
      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.

`GTK_WIN_POS_NONE` | No influence is made on placement.
`GTK_WIN_POS_CENTER` | Windows should be placed in the center of the screen.
`GTK_WIN_POS_MOUSE` | Windows should be placed at the current mouse position.
`GTK_WIN_POS_CENTER_ALWAYS` | Keep window centered as it changes size, etc.
`GTK_WIN_POS_CENTER_ON_PARENT` | Center the window on its transient parent (see `gtk_window_set_transient_for()`).

### 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
    } GtkSortType;

Determines the direction of a sort.

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

### enum GtkDragResult

    typedef enum
    {
      GTK_DRAG_RESULT_SUCCESS,
      GTK_DRAG_RESULT_NO_TARGET,
      GTK_DRAG_RESULT_USER_CANCELLED,
      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.

`GTK_DRAG_RESULT_SUCCESS` | The drag operation was successful
`GTK_DRAG_RESULT_NO_TARGET` | No suitable drag target
`GTK_DRAG_RESULT_USER_CANCELLED` | The user cancelled the drag operation
`GTK_DRAG_RESULT_TIMEOUT_EXPIRED` | The drag operation timed out
`GTK_DRAG_RESULT_GRAB_BROKEN` | The pointer or keyboard grab used for the drag operation was broken
`GTK_DRAG_RESULT_ERROR` | The drag operation failed due to some unspecified error
