ObjectWrap.bindProperty

Creates a binding between source_property on source and target_property on target.

Whenever the source_property is changed the target_property is updated using the same value. For instance:

g_object_bind_property (action, "active", widget, "sensitive", 0);

Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.

If flags contains [gobject.types.BindingFlags.Bidirectional] then the binding will be mutual: if target_property on target changes then the source_property on source will be updated as well.

The binding will automatically be removed when either the source or the target instances are finalized. To remove the binding without affecting the source and the target you can just call [gobject.object.ObjectWrap.unref] on the returned #GBinding instance.

Removing the binding by calling [gobject.object.ObjectWrap.unref] on it must only be done if the binding, source and target are only used from a single thread and it is clear that both source and target outlive the binding. Especially it is not safe to rely on this if the binding, source or target can be finalized from different threads. Keep another reference to the binding and use [gobject.binding.Binding.unbind] instead to be on the safe side.

A #GObject can have multiple bindings.
