## Types and Values

### enum GtkBaselinePosition

Whenever a container has some form of natural row it may align children in that row along a common typographical baseline. If the amount of verical space in the row is taller than the total requested height of the baseline-aligned children then it can use a GtkBaselinePosition to select where to put the baseline inside the extra availible space.

#### Members

GTK_BASELINE_POSITION_TOP | Align the baseline at the top |
GTK_BASELINE_POSITION_CENTER | Center the baseline |
GTK_BASELINE_POSITION_BOTTOM | Align the baseline at the bottom |

Since: 3.10

### enum GtkDeleteType

GTK_MOVEMENT_PARAGRAPH_ENDS | Move to either end of a paragraph |
GTK_MOVEMENT_PAGES | Move by pages |
GTK_MOVEMENT_BUFFER_ENDS | Move to ends of the buffer |
GTK_MOVEMENT_HORIZONTAL_PAGES | Move horizontally by pages |

### enum GtkOrientation

Represents the orientation of widgets and other objects which can be switched between horizontal and vertical orientation on the fly, like GtkToolbar or GtkGesturePan.

#### Members

GTK_ORIENTATION_VERTICAL | The element is in vertical orientation. |

### enum GtkPackType

Represents the packing location GtkBox children. (See: GtkVBox, GtkHBox, and GtkButtonBox).

#### Members

### enum GtkPositionType

#### Members

GTK_POS_LEFT | The feature is at the left edge. |
GTK_POS_RIGHT | The feature is at the right edge. |
GTK_POS_TOP | The feature is at the top edge. |
GTK_POS_BOTTOM | The feature is at the bottom edge. |

### enum GtkReliefStyle

Indicated the relief to be drawn around a GtkButton.

#### Members

GTK_RELIEF_NORMAL | Draw a normal relief. |
GTK_RELIEF_HALF | A half relief. Deprecated in 3.14, does the same as `GTK_RELIEF_NORMAL` |
GTK_RELIEF_NONE | No relief. |

### enum GtkScrollStep

#### Members

GTK_SCROLL_PAGES | Scroll by pages. |
GTK_SCROLL_ENDS | Scroll to ends. |
GTK_SCROLL_HORIZONTAL_STEPS | Scroll in horizontal steps. |
GTK_SCROLL_HORIZONTAL_PAGES | Scroll by horizontal pages. |
GTK_SCROLL_HORIZONTAL_ENDS | Scroll to the horizontal ends. |

### enum GtkScrollType

Scrolling types.

#### Members
