Detailed Description

Bind two object properties.

Glib::Binding is the representation of a binding between a property on a Glib::ObjectBase instance (or source) and another property on another Glib::ObjectBase instance (or target). Whenever the source property changes, the same value is applied to the target property; for instance, the following binding:

Glib::Binding::bind_property(object1->property_a(), object2->property_b());

will cause property_b() of object2 to be updated every time the value of property_a() of object1 changes.

It is possible to create a bidirectional binding between two properties of two Glib::ObjectBase instances, so that if either property changes, the other is updated as well, for instance:

Glib::Binding::bind_property(object1->property_a(), object2->property_b(),

Glib::Binding::Flags::BIDIRECTIONAL);

will keep the two properties in sync.

It is also possible to set a custom transformation function (in both directions, in case of a bidirectional binding) to apply a custom transformation from the source value to the target value before applying it; for instance, the following binding:

bool celsius_to_fahrenheit(const double& celsius, double& fahrenheit);
bool fahrenheit_to_celsius(const double& fahrenheit, double& celsius);
Glib::Binding::bind_property(adjustment1->property_value(),
  adjustment2->property_value(), Glib::Binding::Flags::BIDIRECTIONAL,
  sigc::ptr_fun(celsius_to_fahrenheit), sigc::ptr_fun(fahrenheit_to_celsius));

will keep property_value() of the two adjustments in sync; the celsius_to_fahrenheit() function will be called whenever property_value() of adjustment1 changes and will transform the current value of the property before applying it to property_value() of adjustment2.

Vice versa, the fahrenheit_to_celsius() function will be called whenever property_value() of adjustment2 changes, and will transform the current value of the property before applying it to property_value() of adjustment1.

Note that Glib::Binding does not resolve cycles by itself; a cycle like

object1->property_A() -> object2->property_B()
object2->property_B() -> object3->property_C()
object3->property_C() -> object1->property_A()

might lead to an infinite loop. The loop, in this particular case, can be avoided if the objects emit the GObject::notify signal only if the value has effectively been changed. A binding is implemented using the GObject::notify signal, so it is susceptible to all the various ways of blocking a signal emission, like Glib::SignalProxyNormal::emission_stop() or g_signal_handler_block().

The binding between the two properties is broken whenever either one of the Glib::ObjectBase instances it refers to is deleted or when unbind() is called. If a RefPtr<Binding> remains after the binding has been broken, get_source() and get_target() return a nullptr. It's not necessary to keep a RefPtr<Binding> in order to keep the binding alive.

Member Typedef Documentation

using Glib::Binding::SlotTransform = sigc::slot<bool(const GValue*, GValue*)>

A slot to be called to transform values in a binding created by bind_property_value().

For instance:

bool on_transform_to(const GValue* from_value, GValue* to_value);

Returns: true if the transformation was successful, and false otherwise.

template <typename T_from , typename T_to >

using Glib::Binding::SlotTypedTransform = sigc::slot<std::optional<T_to> (const T_from&)>

A slot to be called to transform values in a binding created by bind_property().

For instance:

std::optional<int> on_transform_to(const Glib::ustring& from_string);

Returns: a value of type T_to if the transformation was successful, and an empty optional with no value (i.e. std::nullopt) otherwise.

Since glibmm 2.44:

static Glib::RefPtr<Binding> Glib::Binding::bind_property_value	(	const PropertyProxy_Base&	source_property,
		const PropertyProxy_Base&	target_property,
		Flags	flags = `Flags::DEFAULT`,
		const SlotTransform&	transform_to = `{}`,
		const SlotTransform&	transform_from = `{}`
	)

static

Creates a binding between source_property and target_property, allowing you to set the transformation functions to be used by the binding.

If flags contains Glib::Binding::Flags::BIDIRECTIONAL then the binding will be mutual: if target_property changes then the source_property will be updated as well. The transform_from function is only used in case of bidirectional bindings, otherwise it will be ignored.

The binding will automatically be removed when either the source or the target instance is deleted. To remove the binding without affecting the source and the target you can call unbind() on the returned Binding instance.

A Glib::ObjectBase instance can have multiple bindings.

If you supply transformation functions, it is usually easier to use one of the bind_property() overloads, to avoid the use of GValue in the transformation functions.

Parameters

source_property	The source property to bind.
target_property	The target property to bind.
flags	Flags to pass to Binding.
transform_to	The transformation function from the source to the target, or an empty slot to use the default.
transform_from	The transformation function from the target to the source, or an empty slot to use the default.

Returns: The Binding instance representing the binding between the two Glib::ObjectBase instances, or nullptr in case of error.
