Assign a CSS style to portlet
Project description
hexagonit.portletstyle is a Plone 4.x add-on that allows you to assign a CSS style to a portlet. You can chose from a list of pre-defined (configurable through Plone Control Panel) classes.
Installation
To install hexagonit.portletstyle you simply add hexagonit.portletstyle to the list of eggs in your buildout, run buildout and restart Plone. Then, install hexagonit.portletstyle using the Add-ons control panel.
Usage
Click on Manage portlets and add or edit a portlet. Select your desired portlet style from the Portlet Style drop-down menu and save. That’s it.
Default portlet styles
By default, this package gives you three default portlet styles:
noheader
nofooter
noheader nofooter
Managing available portlet styles
You can add, edit and remove available portlet styles by going to the Plone Control Panel and clicking on the Portlet Styles configlet. Pointing your browser directly to http://<zope_ip>:<zope_port>/<plone_id>/@@portletstyles also does the trick.
Supported portlets
As of this moment, the following portlets are supported (as in, you can select a style when editing them):
Events portlet
Navigation portlet
News portlet
Recently changed items portlet
RSS portlet
Collection portlet
Static text portlet
The rest of out-of-the-box Plone portlets are non-editable ones as you normally need only one instance per site. For these (and other) reasons the following portlets do not support choosing a style for them:
Calendar portlet
Classic portlet
Language portlet
Login portlet
Review portlet
Search portlet
Styling third-party portlets
Follow the steps below to convince your third-party portlets to support selecting a style for them.
Portlet Assignment
You portlet’s Assignment class must have an __init__() and inside this method it must call base assignment’s __init__(). To put it in other words, plone.app.portlets.portlets.base.Assignment (from which you portlet’s Assignment is likely inheriting from) has an __init__() method that sets the self.portlet_style value. You need to call this __init__() from your portlet’s assignment’s __init__().
An example of how this can be achieved:
from plone.app.portlets.portlets import base
class Assignment(base.Assignment):
implements(IMyCustomPortlet)
def __init__(self, *args, **kwargs):
base.Assignment.__init__(self, *args, **kwargs)
self.foo = kwargs.get('foo', 5)
self.bar = kwargs.get('bar', "bar")
Portlet AddForm
Each portlet also has an AddForm class with a create method. This method must also pass the portlet style as a parameter. To make things simpler, just pass in the entire data.
class AddForm(base.AddForm):
form_fields = form.Fields(IMyCustomPortlet)
def create(self, data):
return Assignment(**data)
Template
Use the style in the template to assign an additional CSS class to your portlet:
<dl class="portlet portletMyCustom"
tal:attributes="class string:portlet portletMyCustom ${view/portlet_style}"
i18n:domain="plone">
TODO
use in the wild
better @@portletstyles control panel configlet UI: key (CSS class) - value (title) type records
maybe patch non-editable portlets (login, calendar, search, etc.)
