Detailed Description

A container for packing widgets in a single row or column.

The Gtk::Box widget arranges child widgets into a single row or column, depending upon the value of its Gtk::Orientable::property_orientation() property. Within the other dimension, all children are allocated the same size. Of course, Gtk::Widget::set_halign() and Gtk::Widget::set_valign() can be used on the children to influence their allocation.

Use repeated calls to append() to pack widgets into a Gtk::Box from start to end. Use remove() to remove widgets from the Gtk::Box. insert_child_after() can be used to add a child at a particular position.

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

Use set_spacing() to determine how much space will be minimally placed between all children in the Gtk::Box. Note that spacing is added between the children.

Use reorder_child_after() and reorder_child_at_start() to move a child to a different place in the box.

Returns: The baseline position.

bool Gtk::Box::get_homogeneous ( ) const

Returns whether the box is homogeneous (all children are the same size).

See set_homogeneous().

Returns: true if the box is homogeneous.

int Gtk::Box::get_spacing ( ) const

Gets the value set by set_spacing().

Returns: Spacing between children.

static GType Gtk::Box::get_type ( )

static

GtkBox* Gtk::Box::gobj ( )

inline

Provides access to the underlying C GObject.

const GtkBox* Gtk::Box::gobj ( ) const

inline

Provides access to the underlying C GObject.

void Gtk::Box::insert_child_after	(	Widget&	child,
		const Widget&	sibling
	)

Inserts child in the position after sibling in the list of children.

Parameters

child	The Gtk::Widget to insert.
sibling	The sibling to move child after.

void Gtk::Box::insert_child_at_start ( Widget& child )

Inserts child in the first position in the list of children.

Parameters

child The Gtk::Widget to insert.

Box& Gtk::Box::operator= ( Box&& src )

noexcept

Box& Gtk::Box::operator= ( const Box& )

delete

void Gtk::Box::prepend ( Gtk::Widget& child )

Adds child as the first child to box.

Parameters

child The Gtk::Widget to prepend.

Glib::PropertyProxy< BaselinePosition > Gtk::Box::property_baseline_position ( )

The position of the baseline aligned widgets if extra space is available.

Default value: Gtk::BaselinePosition::CENTER

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

Glib::PropertyProxy_ReadOnly< BaselinePosition > Gtk::Box::property_baseline_position ( ) const

The position of the baseline aligned widgets if extra space is available.

Default value: Gtk::BaselinePosition::CENTER

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

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

Whether the children should all be the same size.

Default value: false

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

Default value: false

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

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

The amount of space between children.

Default value: 0

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

Default value: 0

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

void Gtk::Box::remove ( Gtk::Widget& child )

Removes a child widget from box, after it has been added with append(), prepend(), or insert_child_after().

Parameters

child The child to remove.

void Gtk::Box::reorder_child_after	(	Widget&	child,
		const Widget&	sibling
	)

Moves child to the position after sibling in the list of children.

Parameters

child	The Gtk::Widget to move. Must be a child of the Box.
sibling	The sibling to move child after.

void Gtk::Box::reorder_child_at_start ( Widget& child )

Moves child to the first position in the list of children.

Parameters

child The Gtk::Widget to move. Must be a child of the Box.

void Gtk::Box::set_baseline_position ( BaselinePosition position )

Sets the baseline position of a box.

This affects only horizontal boxes with at least one baseline aligned child. If there is more vertical space available than requested, and the baseline is not allocated by the parent then position is used to allocate the baseline wrt the extra space available.

Parameters

position A Gtk::BaselinePosition.

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.
