Coupling use cases
==================

Existing use cases
==================


Package Views, Helper
---------------------

Several widgets provide a view to package manager. For instance:

    - :obj:`~openalea.oalab.package.widgets.PackageViewWidget`
    - :obj:`~openalea.oalab.package.widgets.PackageCategorieViewWidget`
    - :obj:`~openalea.oalab.package.widgets.PackageSearchWidget`

Each package, node or data provide a documentation. We want to display this
documentation on a special place, the HelpApplet widget, if available.
We do not want to force use of this applet. Package View can run without it.


NodeFactoryView, MainWindow
---------------------------

    - :obj:`~openalea.visualea.node_treeview.NodeFactoryView`
    - :obj:`~openalea.visualea.mainwindow.MainWindow`
