### enum 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.

#### Members

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

Describes a widget state. Widget states are used to match the widget against CSS pseudo-classes. Note that GTK extends the regular CSS classes and sometimes uses different names.

#### Members

GTK_STATE_FLAG_NORMAL | State during normal operation. |
GTK_STATE_FLAG_ACTIVE | Widget is active. |
GTK_STATE_FLAG_PRELIGHT | Widget has a mouse pointer over it. |
GTK_STATE_FLAG_SELECTED | Widget is selected. |

GTK_STATE_FLAG_DIR_RTL | Widget is in right-to-left text direction. Since 3.8 |

### enum 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.

#### Members

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 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.

#### Members

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

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.

#### Members

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

### enum GtkSortType

#### Members

#### Members

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. |

### enum GtkJunctionSides
