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

Constructor & Destructor Documentation

◆ LayoutChild() [1/2]

Gtk::LayoutChild::LayoutChild ( LayoutChild && src)
noexcept

◆ ~LayoutChild()

Gtk::LayoutChild::~LayoutChild ( )
overridenoexcept

◆ LayoutChild() [2/2]

Gtk::LayoutChild::LayoutChild ( )
protected

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

◆ 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 )
related

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

Parameters
objectThe C instance.
take_copyFalse 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.
