Manager is the Components Manager package of Umbra, sIBL_GUI and sIBL_Reporter.
Project description
Introduction
Manager is the Components Manager package of Umbra, sIBL_GUI and sIBL_Reporter. Components are simple python packages extending capabilities of their host application.
Installation
The following dependencies are needed:
Python 2.6.7 or Python 2.7.3: http://www.python.org/
To install Manager from the Python Package Index you can issue this command in a shell:
pip install Manager
or this alternative command:
easy_install Manager
You can also directly install from Github source repository:
git clone git://github.com/KelSolaar/Manager.git cd Manager python setup.py install
If you want to build the documentation you will also need:
Usage
Please refer to Manager - Api for precise usage examples.
A Component package contains at least a resource .rc description file and a main module:
testsComponentA ├── __init__.py ├── testsComponentA.py └── testsComponentA.rc
The description file is a configuration style file with a structure similar to what you would find in Microsoft Windows INI files:
[Component] Name = core.testsComponentA Title = Tests Component A Module = testsComponentA Object = TestsComponentA Version = 1.0 [Informations] Author = Thomas Mansencal Email = thomas.mansencal@gmail.com Url = http://www.hdrlabs.com/ Description = Core tests Component A.
Given the following directories structure:
core
├── __init__.py
├── testsComponentA
│ ├── __init__.py
│ ├── testsComponentA.py
│ └── testsComponentA.rc
└── testsComponentB
├── __init__.py
├── testsComponentB.py
└── testsComponentB.rc
Instantiating the Components Manager is done the following way:
>>> manager = Manager(("./manager/tests/testsManager/resources/components/core",))
>>> manager.registerComponents()
True
>>> manager.listComponents()
['core.testsComponentA', 'core.testsComponentB']
>>> manager.instantiateComponents()
True
>>> manager.getInterface("core.testsComponentA")
<testsComponentA.TestsComponentA object at 0x11dd990>
manager.componentsManager.Manager.getInterface(name) method returns the interface of given Component, in the previous example it’s the object declared in the description file by this statement: Object = TestsComponentA.
Three base Components are provided by default:
manager.component.Component
manager.qobjectComponent.QObjectComponent
manager.qwidgetComponent.QWidgetComponent
When inheriting from those Components, one have to reimplement the following methods for all the Components types:
activate
deactivate
activated attribute has to be set accordingly in the methods implementation.
When implementing a manager.qwidgetComponent.Component or manager.qobjectComponent.QObjectComponent, the following methods are also needed:
initialize
uninitialize
initialized attribute has to be set accordingly in the methods implementation.
Or alternatively, those methods when implementing a manager.qwidgetComponent.QWidgetComponent:
initializeUi
uninitializeUi
initializedUi attribute has to be set accordingly in the methods implementation.
Reference Component implementation example class:
class TestsComponentA(Component):
def __init__(self, name=None):
Component.__init__(self, name=name)
self.deactivatable = True
def activate(self):
print("> Activating '{0}' Component.".format(self.__class__.__name__))
self.activated = True
return True
def deactivate(self):
print("> Deactivating '{0}' Component.".format(self.__class__.__name__))
self.activated = False
return True
def initialize(self):
print("> Initializing '{0}' Component.".format(self.__class__.__name__))
self.initialized = True
return True
def uninitialize(self):
print("> Uninitializing '{0}' Component.".format(self.__class__.__name__))
self.initialized = False
return True
