## Functions

### gtk_layout_new ()

    GtkWidget *
    gtk_layout_new (GtkAdjustment *hadjustment,
                    GtkAdjustment *vadjustment);

Creates a new GtkLayout. Unless you have a specific adjustment you'd like the layout to use for scrolling, pass `NULL` for `hadjustment` and `vadjustment` .

#### Parameters

hadjustment | horizontal scroll adjustment, or `NULL`. | [allow-none]
vadjustment | vertical scroll adjustment, or `NULL`. | [allow-none]

#### Returns

a new GtkLayout

### gtk_layout_put ()

    void
    gtk_layout_put (GtkLayout *layout,
                    GtkWidget *child_widget,
                    gint x,
                    gint y);

Adds `child_widget` to `layout` , at position (`x` ,`y` ). `layout` becomes the new parent container of `child_widget` .

#### Parameters

layout | a GtkLayout |
child_widget | child widget |
x | X position of child widget |
y | Y position of child widget |

### gtk_layout_move ()

    void
    gtk_layout_move (GtkLayout *layout,
                     GtkWidget *child_widget,
                     gint x,
                     gint y);

Moves a current child of `layout` to a new position.

#### Parameters

layout | a GtkLayout |
child_widget | a current child of `layout` |
x | X position to move to |
y | Y position to move to |

### gtk_layout_set_size ()

    void
    gtk_layout_set_size (GtkLayout *layout,
                         guint width,
                         guint height);

Sets the size of the scrollable area of the layout.

#### Parameters

layout | a GtkLayout |
width | width of entire scrollable area |
height | height of entire scrollable area |

### gtk_layout_get_size ()

    void
    gtk_layout_get_size (GtkLayout *layout,
                         guint *width,
                         guint *height);

Gets the size that has been set on the layout, and that determines the total extents of the layout's scrollbar area. See `gtk_layout_set_size()`.

#### Parameters

layout | a GtkLayout |
width | location to store the width set on `layout` , or `NULL`. | [out][allow-none]
height | location to store the height set on `layout` , or `NULL`. | [out][allow-none]

### gtk_layout_freeze ()

    void
    gtk_layout_freeze (GtkLayout *layout);

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

This is a deprecated function, it doesn't do anything useful.

#### Parameters

layout | a GtkLayout |

### gtk_layout_thaw ()

    void
    gtk_layout_thaw (GtkLayout *layout);

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

This is a deprecated function, it doesn't do anything useful.

#### Parameters

layout | a GtkLayout |

### gtk_layout_get_hadjustment ()

    GtkAdjustment *
    gtk_layout_get_hadjustment (GtkLayout *layout);

This function should only be called after the layout has been placed in a GtkScrolledWindow or otherwise configured for scrolling. It returns the GtkAdjustment used for communication between the horizontal scrollbar and `layout` .

See GtkScrolledWindow, GtkScrollbar, GtkAdjustment for details.

#### Parameters

layout | a GtkLayout |

#### Returns

horizontal scroll adjustment.

[transfer none]

### gtk_layout_get_vadjustment ()

    GtkAdjustment *
    gtk_layout_get_vadjustment (GtkLayout *layout);

This function should only be called after the layout has been placed in a GtkScrolledWindow or otherwise configured for scrolling. It returns the GtkAdjustment used for communication between the vertical scrollbar and `layout` .

See GtkScrolledWindow, GtkScrollbar, GtkAdjustment for details.

#### Parameters

layout | a GtkLayout |

#### Returns

vertical scroll adjustment.

[transfer none]

### gtk_layout_set_hadjustment ()
