## Detailed Description

The Box widget organizes child widgets into a rectangular area.

The rectangular area of a Box is organized into either a single row or a single column of child widgets depending upon the orientation. Thus, all children of a Box are allocated one dimension in common, which is the height of a row, or the width of a column.

Gtk::Box uses a notion of packing. Packing refers to adding widgets with reference to a particular position in a Gtk::Container. There are two reference positions: the start and the end of the box. For a vertical Box, the start is defined as the top of the box and the end is defined as the bottom. For a horizontal Box the start is defined as the left side and the end is defined as the right side. Use repeated calls to pack_start() to pack widgets into a Gtk::Box from start to end. Use pack_end() to add widgets from end to start. You may intersperse these calls and add widgets from both ends of the same Gtk::Box. The last widget added with pack_start() will be placed just before the last widget added with pack_end()

Because Gtk::Box is a Gtk::Container, you may also use Gtk::Container::add() to insert widgets, and they will be packed as if with pack_start(). Use Gtk::Container::remove() to remove widgets.

Use set_homogeneous() to specify whether or not all children of the Gtk::Box occupy the same amount of space.

Use set_spacing() to determine the minimum space placed between all children in the Gtk::Box. Note that spacing is added between the children, while padding added by gtk_box_pack_start() or gtk_box_pack_end() is added on either side of the widget it belongs to.

Use reorder_child() to move a child widget to a different place in the box.

Use set_child_packing() to reset the pack options and padding attributes of any Gtk::Box child. Use query_child_packing() to query these fields.

void Gtk::Box::pack_end | ( | Widget& | child,
|  | bool | expand,
|  | bool | fill,
|  | guint | padding = `0`
| ) |  |

Adds child to box, packed with reference to the end of box.

The child is packed after (away from end of) any other child packed with reference to the end of box.

Parameters:

  child | The Gtk::Widget to be added to box.
  expand | `true` if the new child is to be given extra space allocated to box. The extra space will be divided evenly between all children of box that use this option.
  fill | `true` if space given to child by the expand option is actually allocated to child, rather than just padding it. This parameter has no effect if expand is set to `false`. A child is always allocated the full height of a horizontal Gtk::Box and the full width of a vertical Gtk::Box. This option affects the other dimension.
  padding | Extra space in pixels to put between this child and its neighbors, over and above the global amount specified by Gtk::Box::property_spacing() property. If child is a widget at one of the reference ends of box, then padding pixels are also put between child and the reference edge of box.

void Gtk::Box::pack_end | ( | Widget& | child,
|  | PackOptions | options = `PACK_EXPAND_WIDGET`,
|  | guint | padding = `0`
| ) |  |

Right side insert a widget to a box.

Parameters:

  child | A Widget to be added to box.
  options | Controls how the widget expands to fill space, and how the space around them is used.
  padding | Padding that is added on either side of the widget. This is different to spacing set when the box is created (or with set_spacing()) - spacing is added between objects, and padding is added on either side of an object.

void Gtk::Box::pack_start | ( | Widget& | child,
|  | bool | expand,
|  | bool | fill,
|  | guint | padding = `0`
| ) |  |

Left side insert a widget to a box.

The expand argument to pack_start() or pack_end() controls whether the widgets are laid out in the box to fill in all the extra space in the box so the box is expanded to fill the area allocated to it (`true`). Or the box is shrunk to just fit the widgets (`false`). Setting expand to `false` will allow you to do right and left justifying of your widgets. Otherwise, they will all expand to fit in the box, and the same effect could be achieved by using only one of pack_start() or pack_end() functions.

The fill argument to the pack_start()/pack_end() functions control whether the extra space is allocated to the objects themselves (`true`), or as extra padding in the box around these objects (`false`). It only has an effect if the expand argument is also `true`.

The difference between spacing (set when the box is created) and padding (set when elements are packed) is, that spacing is added between objects, and padding is added on either side of an object.

Parameters:

  child | The Gtk::Widget to be added to box.
  expand | `true` if the new child is to be given extra space allocated to box. The extra space will be divided evenly between all children that use this option.
  fill | `true` if space given to child by the expand option is actually allocated to child, rather than just padding it. This parameter has no effect if expand is set to `false`. A child is always allocated the full height of a horizontal Gtk::Box and the full width of a vertical Gtk::Box. This option affects the other dimension.
  padding | Extra space in pixels to put between this child and its neighbors, over and above the global amount specified by Gtk::Box::property_spacing() property. If child is a widget at one of the reference ends of box, then padding pixels are also put between child and the reference edge of box.

void Gtk::Box::pack_start | ( | Widget& | child,
|  | PackOptions | options = `PACK_EXPAND_WIDGET`,
|  | guint | padding = `0`
| ) |  |

Left side insert a widget to a box.

Parameters:

  child | A Widget to be added to box.
  options | Controls how the widget expands to fill space, and how the space around them is used.
  padding | Padding that is added on either side of the widget. This is different to spacing set when the box is created (or with set_spacing()) - spacing is added between objects, and padding is added on either side of an object.

Glib::PropertyProxy< bool > Gtk::Box::property_homogeneous | ( |  | ) |

Whether the children should all be the same size.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< bool > Gtk::Box::property_homogeneous | ( |  | ) | const

Whether the children should all be the same size.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy< int > Gtk::Box::property_spacing | ( |  | ) |

The amount of space between children.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< int > Gtk::Box::property_spacing | ( |  | ) | const

The amount of space between children.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

void Gtk::Box::reorder_child | ( | Widget& | child,
|  | int | pos
| ) |  |

Moves child to a new position in the list of box children.

The list is the <structfield>children</structfield> field of Gtk::Box-struct, and contains both widgets packed Gtk::PACK_START as well as widgets packed Gtk::PACK_END, in the order that these widgets were added to box.

A widget's position in the box children list determines where the widget is packed into box. A child widget at some position in the list will be packed just after all other widgets of the same packing type that appear earlier in the list.

Parameters:

  child | The Gtk::Widget to move.
  position | The new position for child in the list of children of box, starting from 0. If negative, indicates the end of the list.

void Gtk::Box::set_homogeneous | ( | bool | homogeneous = `true` | ) |

Sets the Gtk::Box::property_homogeneous() property of box, controlling whether or not all children of box are given equal space in the box.

Parameters:

  homogeneous | A boolean value, `true` to create equal allotments, `false` for variable allotments.

void Gtk::Box::set_spacing | ( | int | spacing | ) |

Sets the Gtk::Box::property_spacing() property of box, which is the number of pixels to place between children of box.

Parameters:

  spacing | The number of pixels to put between children.
