Manipulator: Python API
Initial support for Python/Manipulator integration from 'custom-manipulators' branch. Supports: - Registering custom manipulators & manipulator-groups. - Modifying RNA properties, custom values via get/set callbacks, or invoking an operator. - Drawing shape presets for Python defined manipulators (arrow, circle, face-maps) Limitations: - Only float properties supported. - Drawing only supported via shape presets. (we'll likely want a way to define custom geometry or draw directly). - When to refresh, recalculate manipulators will likely need integration with notifier system. Development will be continued in the 2.8 branch

Manipulator Overview
|
||||
--------------------
|
||||
|
||||
Manipulators are created using two classes.
|
||||
|
||||
- :class:`bpy.types.ManipulatorGroup` - stores a list of manipulators.
|
||||
|
||||
The manipulator group is associated with a space and region type.
|
||||
- :class:`bpy.types.Manipulator` - a single item which can be used.
|
||||
|
||||
Each manipulator group has a collection of manipulators which it manages.
|
||||
|
||||
The following example shows a manipulator group with a single,
|
||||
manipulator used to control a lamp objects energy.
|
||||
|
||||
.. literalinclude:: __/__/__/release/scripts/templates_py/manipulator_simple.py
|
||||
|
||||
|
||||
It's also possible to use a manipulator to run an operator.
|
||||
|
||||
.. literalinclude:: __/__/__/release/scripts/templates_py/manipulator_operator_target.py
|
||||
|
||||
This more comprehensive example shows how an operator can create a temporary manipulator group to adjust its settings.
