class GObject::BindingGroup

Overview

The #GBindingGroup can be used to bind multiple properties from an object collectively.

Use the various methods to bind properties from a single source object to multiple destination objects. Properties can be bound bidirectionally and are connected when the source object is set with g_binding_group_set_source().

Defined in:

lib/gi-crystal/src/auto/g_object-2.0/binding_group.cr

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def bind(source_property : String, target : GObject::Object, target_property : String, flags : GObject::BindingFlags) : Nil #

Creates a binding between source_property on the source object and target_property on target. Whenever the source_property is changed the target_property is updated using the same value. The binding flag %G_BINDING_SYNC_CREATE is automatically specified.

See g_object_bind_property() for more information.


[View source]
def bind_full(source_property : String, target : GObject::Object, target_property : String, flags : GObject::BindingFlags, transform_to : GObject::Closure | Nil, transform_from : GObject::Closure | Nil) : Nil #

Creates a binding between source_property on the source object and target_property on target, allowing you to set the transformation functions to be used by the binding. The binding flag %G_BINDING_SYNC_CREATE is automatically specified.

See g_object_bind_property_full() for more information.


[View source]
def dup_source : GObject::Object | Nil #

Gets the source object used for binding properties.


[View source]
def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def source : GObject::Object | Nil #

[View source]
def source=(source : GObject::Object | Nil) : Nil #

Sets source as the source object used for creating property bindings. If there is already a source object all bindings from it will be removed.

Note that all properties that have been bound must exist on source.
