Update Example
|
|
++++++++++++++
|
|
|
|
It can be useful to perform an action when a property is changed and can be
|
|
used to update other properties or synchronize with external data.
|
|
|
|
All properties define update functions except for CollectionProperty.
|
|
|
|
.. warning::
|
|
|
|
Remember that these callbacks may be executed in threaded context.
|
|
|
|
.. warning::
|
|
|
|
If the property belongs to an Operator, the update callback's first
|
|
parameter will be an OperatorProperties instance, rather than an instance
|
|
of the operator itself. This means you can't access other internal functions
|
|
of the operator, only its other properties.
