collective.panels 1.3.1

Examples

Front page

Instead of, or in addition to, a page acting as the default content on a folder, you can create a collage of portlets and display it below an introductory text.

There’s a lot of flexibility because you can integrate the panel display with Plone’s built-in content views. For instance, you could provide a search interface in addition to the standard folder listing.

Supplement static content

Use panels to add portlets above or below a static page.

Features or advertisement

Add panels to the ‘portal top’ location which by default renders just below the section navigation for an impressive effect.

Usage

To create a new panel, or manage existing ones, the editor clicks the “Manage panels” link appearing in the footer (it links to @@manage-panels) — similar to Plone’s column portlets.

The management view is an overlay of the default content view.

Creating a new panel

To create a new panel, there’s a collapsible form appearing just below the page title (“Add panel”).

If no panels exist already, the add form appears open to begin with.

Then, simply choose a location (a default choice is already provided), and select a layout. Then add portlets using the “Manage panel” form (see next).

Managing existing panels

In the management interface, a collapsible form appears below existing panels (“Manage panel”).

This is similar to Plone’s standard portlet interface and in fact uses it directly.

It provides options to add a new portlet, change panel layout or manage existing portlet assignments.

Locations

The management interface checks with Plone’s viewlet visibility settings to list only the applicable adding locations. This allows an administrator to visit the portal’s @@manage-viewlets screen and put a restriction on panel locations.

Adding additional locations is currently not supported. The limitation here is that Plone’s viewlet manager framework does not provide labels, or other enumeration.

Layouts

There’s a choice of layout for each panel, selected when the panel is first added, with an option to change later on. These layouts are registered as components using an included ZCML-directive.

Use the directive to add additional layouts:

<browser:panel
    name="example"
    title="Example"
    template="templates/example.pt"
    layer=".interfaces.IThemeSpecific"
    />

1.3.1 (2012-06-15)

Features:

• Added panel-${n} classes to the panel elements.

• Added portlet-${n} classes to the wrapper elements that render the portlet.

• The panel elements now have a class that matches the layout id.

• Added new spacing ‘small’, set at 0.55%.

1.3 (2012-06-15)

Features:

• A panel location can now be configured to be local to nearest site context. For instance, the footer manager can be configured in this way such that it’s possible to use panels to create a site footer (which will be shown on all pages within that site).

• Layouts now have a required description attribute which will be shown in the “Manage panels” fieldset (instead of the title, which is usually very short and non-descriptive).

Bugfixes:

• Fixed issue where the error message would not get correctly rendered.

• Fixed issue #9: “Unexpected non-class object while iterating over viewlet managers”.

1.2.3 (2012-06-08)

Bugfixes:

• The portlet settings dictionary was missing. Not strictly a bug, but the IPortletAssignmentSettings API exists to provide this information to the column renderer and we should provide it, too, for the portlet renderer wrapper template.

• Panel manager must provide get method. This fixes issue #8.

1.2.2 (2012-05-18)

Bugfixes:

• Fixed an issue that prevented the versioning tool to check in a document when a panel had been added. This fixes issue #5.

1.2.1 (2012-05-17)

Bugfixes:

• Fixed an issue with incompatible template syntax.

• Fixed an issue where a panel would not correctly return a representation string when not acquisition-wrapped. This addresses issue #5 (but turned out not quite to fix it entirely).

1.2 (2012-05-16)

Features:

• Added three new vertical layouts, assigned respectively 1/3, 1/2 and 2/3 page width.

• Added option to select standard, double or triple spacing, all of which are given as a percentage of the page width.

Bugfixes:

• Fixed an issue with the panel adding view that made it impossible to add panels to content marked as private (the request would be unauthorized). This fixes issue #6.

• Views and resources are now registered against a package-specific browser layer. This ensures that the user interface is not available unless the product is installed (issue #7).

1.1 (2012-05-15)

Changes:

• Layout titles are now simply letters: A, B, C, etc. It turned out to be difficult to provide a short, descriptive title for each layout.

Features:

• Improved styling of adding interface.

• Added two new horizontal layouts that assign a fixed width of 1/3 to respectively the left-most and the right-most assignment.

Translation:

• Added Danish translation.

Bugfixes:

• Fixed layout “Left” in the case of a single assignment.

• The addable portlets check is now robust to misconfigured adding views and will log a warning instead of letting the exception trickle through.

• Assignments now get unique names. For example, if two calendar assignments are added, the second assignment gets the name “calendar-1”.

• The panel info hash now correctly encodes a valid portlet manager. This fixes an issue where KSS-enabled portlets would operate incorrectly.

• The panel assignment class and traverser now inherit from OFS.Traversable.Traversable and implement the getId method. This fixes an issue where a physical path would not be correctly computed.

1.0.2 (2012-04-19)

Bugfixes:

• Fixed issue where you could not add portlets to a panel other than the first (for a given manager). This fixes issue #3.

1.0.1 (2012-04-17)

Bugfixes:

• Fixed template formatting issue.

• Added markup from Plone’s column renderer, wrapping each portlet in a structure that provides a unique portlet hash. Also, use a “safe” rendering method such that rendering may fail gracefully.

1.0 (2012-04-12)

• Initial public release.
