Since 2.26Bidirectional binding; if either the property of the source or the property of the target changes, the other is updated.
The default binding; if the source property changes, the target property is updated with its value.
If the two properties being bound are
booleans, setting one to true will result in the other being
set to false and vice versa. This flag will only work for
boolean properties, and cannot be used when passing custom
transformation functions to g_object_bind_property_full().
Synchronize the values of the source and target properties when creating the binding; the direction of the synchronization is always from the source to the target.
Flags to be passed to
g_object_bind_property()org_object_bind_property_full().This enumeration can be extended at later date.
