2) several imporvments for the link-widget - it uses now popups, if the link-registry says so for a given app - new widget to add an already linked entry of an other app (used in PM so far) - new widget to display a single link to view a linked entry

/**
|
|
* eTemplate Extension: several widgets as user-interface for the link-class
|
|
*
|
|
* All widgets use the link-registry, to "know" which apps use popups (and what size).
|
|
* If run in a popup and the app uses no popups, a target will be set, to open a new full decorated window.
|
|
*
|
|
* The class contains the following widgets:
|
|
* - link: Show a link to one linked entry specified by an array with keys app, id and optional title and help-message
|
|
* - link-to: Widget to create links to an other entries of link-aware apps
|
|
* If an id was set, this widgets creats the links without further interaction with the calling code.
|
|
* If the entry does not yet exist, the widget returns an array with the new links in the id. After the
|
|
* entry was successful create, bolink::link($app,$new_id,$arr) has to be called to create the links!
|
|
* - link-list: Widget to shows the links to an entry in a table with an unlink icon for each link
|
|
* - link-string: comma-separated list of link-titles with a link to its view method, value is like get_links()
|
|
* or array with keys to_app and to_id (widget calls then get_links itself)
|
|
* - link-add: Add a new entry of the select app, which is already linked to a given entry
|
|
*
|
|
*<code>
|
|
* $content[$name] = array(
|
|
* 'to_app' => // I string appname of the entry to link to
|
|
* 'to_id' => // IO int id of the entry to link to, for new entries 0, returns the array with new links
|
|
* // the following params apply only for the link-to widget!
|
|
* 'no_files' => // I boolean suppress attach-files, default no
|
|
* 'search_label' => // I string label to use instead of search
|
|
* 'link_label' => // I string label for the link button, default 'Link'
|
|
* );
|
|
*</code>
|
|
*
|
|
* This widget is independent of the UI as it only uses etemplate-widgets and has therefor no render-function.
