  GTK_STATE_SELECTED,
  GTK_STATE_INSENSITIVE,
  GTK_STATE_INCONSISTENT,
  GTK_STATE_FOCUSED
} 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_SELECTED: State of a selected item, such the selected row in a list. GTK_STATE_INSENSITIVE: State indicating that the widget is unresponsive to user actions. GTK_STATE_INCONSISTENT: The widget is inconsistent, such as checkbuttons or radiobuttons that aren't either set to TRUE nor FALSE, or buttons requiring the user attention. GTK_STATE_FOCUSED: The widget has the keyboard focus.


enum GtkStateFlags

typedef enum
{
  GTK_STATE_FLAG_ACTIVE       = 1 << 0,
  GTK_STATE_FLAG_PRELIGHT     = 1 << 1,
  GTK_STATE_FLAG_SELECTED     = 1 << 2,
  GTK_STATE_FLAG_INSENSITIVE  = 1 << 3,
  GTK_STATE_FLAG_INCONSISTENT = 1 << 4,
  GTK_STATE_FLAG_FOCUSED      = 1 << 5
} GtkStateFlags;

Describes a widget state.

GTK_STATE_FLAG_PRELIGHT

Widget has a mouse pointer over it.

Widget is inconsistent.

GTK_STATE_FLAG_FOCUSED

Widget has the keyboard focus.

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

enum GtkUpdateType

typedef enum
{
  GTK_UPDATE_CONTINUOUS,
  GTK_UPDATE_DISCONTINUOUS,
  GTK_UPDATE_DELAYED
} GtkUpdateType;

Used by GtkRange to control the policy for notifying value changes.

GTK_UPDATE_CONTINUOUS

Notify updates whenever the value changed

GTK_UPDATE_DISCONTINUOUS

Notify updates when the mouse button has been released

GTK_UPDATE_DELAYED

Space out updates with a small timeout

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

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

GTK_DRAG_RESULT_ERROR

The drag operation failed due to some unspecified error

  GTK_JUNCTION_CORNER_TOPRIGHT = 1 << 1,
  GTK_JUNCTION_CORNER_BOTTOMLEFT = 1 << 2,

  GTK_JUNCTION_TOP    = (GTK_JUNCTION_CORNER_TOPLEFT | GTK_JUNCTION_CORNER_TOPRIGHT),
  GTK_JUNCTION_BOTTOM = (GTK_JUNCTION_CORNER_BOTTOMLEFT | GTK_JUNCTION_CORNER_BOTTOMRIGHT),
  GTK_JUNCTION_LEFT   = (GTK_JUNCTION_CORNER_TOPLEFT | GTK_JUNCTION_CORNER_BOTTOMLEFT),
