|
|
* eTemplate Extension: several widgets as user-interface for the link-class
|
|
*
|
|
* 1) link-to: Widget to create links to an other entries of link-aware apps
|
|
* 2) link-list: Widget to shows the links to an entry and a Unlink Button for each link
|
|
* 3) link-string: comma-separated list of link-titles with a link to its view method, value is like get_links()
|
|
*
|
|
* This widget is independent of the UI as it only uses etemplate-widgets and has therefor no render-function.
