     4 How to create Skin?
       
     5 ===================
       
     6 
       
     7 A Skin is a tagging interface for associating media, javascript and CSS resources to a **renderer**
       
     8 
       
     9 1) Configuring resource library
       
    10 -------------------------------
       
    11 
       
    12 
       
    13 .. code-block:: python
       
    14 
       
    15     from fanstatic import Library, Resource
       
    16     from pyams_default_theme import pyams_default_theme
       
    17 
       
    18     #Library(name, folder_path)
       
    19     library = Library('mycms', 'resources')
       
    20 
       
    21     #Resource(library, path_to_static)
       
    22     mycms_css = Resource(library, 'css/mystyle.css',)
       
    23 
       
    24 
       
    25     mycms_js = Resource(library, 'js/pyams-default.js',
       
    26                         depends=(pyams_default_theme, )
       
    27                         bottom=True
       
    28                         )
       
    29 
       
    30 
       
    31 :py:class:`Resource` can include others resources already defined with *depends* attribute, here `pyams_default_theme`.
       
    32 
       
    33 
       
    34 2) Create a new Layer to your skin
       
    35 ----------------------------------
       
    36 
       
    37 Build a new interface inherit from `ICustomLayer`
       
    38 
       
    39 .. code-block:: python
       
    40 
       
    41     class ICustomLayer(ICustomLayer):
       
    42         """skin layer"""
       
    43 
       
    44 Define an utility providing ISkin with the custom label and the layer interface
       
    45 
       
    46 .. code-block:: python
       
    47 
       
    48     @utility_config(name='Custom skin', provides=ISkin)
       
    49     class CustomSkin(object):
       
    50         """custom root skin"""
       
    51 
       
    52         label = _("Custom: skin")
       
    53         layer = ICustomLayer
       
    54 
       
    55 
       
    56 3) Declare the layer adapter
       
    57 ----------------------------
       
    58 
       
    59 .. code-block:: python
       
    60 
       
    61     @adapter_config(context=(Interface, ICustomLayer, Interface), provides=IResources)
       
    62     class CustomSkinResourcesAdapter(ContextRequestViewAdapter):
       
    63     """Custom skin resources adapter"""
       
    64 
       
    65         def get_resources(self):
       
    66             mycms.need()
       
    67 
       
    68 
       
    69 We have defined a Multiadapter with context=(context, request, view).
       
    70 
       
    71 .. note::
       
    72 
       
    73     In the ZMI website you can now change the default graphical theme by you custom skin
