Create a binding between the writability of key
in the this object and the property
property
of object
.
The property must be boolean; "sensitive" or "visible" properties of widgets are the most likely candidates.
Writable bindings are always uni-directional; changes of the writability of the setting will be propagated to the object property, not the other way.
When the inverted
argument is true, the binding inverts the value as it passes from the
setting to the object, i.e. property
will be set to true if the key is not writable.
Note that the lifecycle of the binding is tied to object
, and that you can have only one binding per object property. If you
bind the same property twice on the same object, the second binding overrides the first one.
