Detailed Description

An object containing layout properties.

Gtk::LayoutChild is the base class for objects that are meant to hold layout properties. If a Gtk::LayoutManager has per-child properties, like their packing type, or the horizontal and vertical span, or the icon name, then the layout manager should use a Gtk::LayoutChild implementation to store those properties.

A Gtk::LayoutChild instance is only ever valid while a widget is part of a layout.

Since gtkmm 3.96:

There is no create() method that corresponds to this constructor, because only derived classes shall be created.

Member Function Documentation

◆ get_child_widget() [1/2]

Widget * Gtk::LayoutChild::get_child_widget ( )

Retrieves the Gtk::Widget associated to the given layout_child.

Returns: A Gtk::Widget.

◆ get_child_widget() [2/2]

const Widget * Gtk::LayoutChild::get_child_widget ( ) const

Retrieves the Gtk::Widget associated to the given layout_child.

Returns: A Gtk::Widget.

◆ get_layout_manager() [1/2]

Glib::RefPtr< LayoutManager > Gtk::LayoutChild::get_layout_manager ( )

Retrieves the Gtk::LayoutManager instance that created the given layout_child.

Returns: A Gtk::LayoutManager.

◆ get_layout_manager() [2/2]

Glib::RefPtr< const LayoutManager > Gtk::LayoutChild::get_layout_manager ( ) const

Retrieves the Gtk::LayoutManager instance that created the given layout_child.

Returns: A Gtk::LayoutManager.

◆ get_type()

static GType Gtk::LayoutChild::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

◆ gobj() [1/2]

GtkLayoutChild * Gtk::LayoutChild::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GtkLayoutChild * Gtk::LayoutChild::gobj ( ) const

inline

Provides access to the underlying C GObject.

◆ gobj_copy()

GtkLayoutChild * Gtk::LayoutChild::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

◆ operator=()

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

noexcept

◆ property_child_widget()

Glib::PropertyProxy_ReadOnly< Widget * > Gtk::LayoutChild::property_child_widget ( ) const

The widget that is associated to the Gtk::LayoutChild instance.

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

◆ property_layout_manager()

Glib::PropertyProxy_ReadOnly< Glib::RefPtr< LayoutManager > > Gtk::LayoutChild::property_layout_manager ( ) const

The layout manager that created the Gtk::LayoutChild instance.

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

◆ wrap()

Glib::RefPtr< Gtk::LayoutChild > wrap	(	GtkLayoutChild *	object,
		bool	take_copy = `false`
	)

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
