/**
* eTemplate Extension: Widget that show only a certain number of data-rows and allows to modifiy the rows shown (scroll).
*
* This widget replaces the old nextmatch-class. It is independent of the UI,
* as it only uses etemplate-widgets and has therefor no render-function
*
* $content[$id] = array( // I = value set by the app, 0 = value on return / output
* 'get_rows' => // I method/callback to request the data for the rows eg. 'notes.bo.get_rows'
* 'filter_label' => // I label for filter (optional)
* 'filter_help' => // I help-msg for filter (optional)
* 'no_filter' => True// I disable the 1. filter
* 'no_filter2' => True// I disable the 2. filter (params are the same as for filter)
* 'no_cat' => True// I disable the cat-selectbox
* 'cat_app' => // I application the cat's should be from, default app in get_rows
* 'template' => // I template to use for the rows, if not set via options
* 'header_left' => // I template to show left of the range-value, left-aligned (optional)
* 'header_right' => // I template to show right of the range-value, right-aligned (optional)
* 'bottom_too' => True// I show the nextmatch-line (arrows, filters, search, ...) again after the rows
* 'never_hide' => True// I never hide the nextmatch-line if less then maxmatch entries
* 'lettersearch' => True// I show a lettersearch
* 'searchletter' => // I0 active letter of the lettersearch or false for [all]
* 'start' => // IO position in list
* 'num_rows' => // IO number of rows to show, defaults to maxmatches from the general prefs
* 'cat_id' => // IO category, if not 'no_cat' => True
* 'search' => // IO search pattern
* 'order' => // IO name of the column to sort after (optional for the sortheaders)
* 'sort' => // IO direction of the sort: 'ASC' or 'DESC'
* 'col_filter' => // IO array of column-name value pairs (optional for the filterheaders)
* 'filter' => // IO filter, if not 'no_filter' => True
* 'filter_no_lang' => True// I set no_lang for filter (=dont translate the options)
* 'filter_onchange'=> 'this.form.submit();' // I onChange action for filter, default: this.form.submit();
* 'filter2' => // IO filter2, if not 'no_filter2' => True
* 'filter2_no_lang'=> True// I set no_lang for filter2 (=dont translate the options)
* 'filter2_onchange'=> 'this.form.submit();' // I onChange action for filter2, default: this.form.submit();
* 'rows' => // O content set by callback
* 'total' => // O the total number of entries
* 'sel_options' => // O additional or changed sel_options set by the callback and merged into $tmpl->sel_options
* 'no_columnselection' => // I turns off the columnselection completly, turned on by default
* 'columnselection-pref' => // I name of the preference (plus 'nextmatch-' prefix), default = template-name
* 'default_cols' => // I columns to use if there's no user or default pref (! as first char uses all but the named columns), default all columns
* 'options-selectcols' => // I array with name/label pairs for the column-selection, this gets autodetected by default. A name => false suppresses a column completly.
* 'return' => // IO allows to return something from the get_rows function if $query is a var-param!
* 'csv_fields' => // I false=disable csv export, true or unset=enable it with auto-detected fieldnames,
* or array with name=>label or name=>array('label'=>label,'type'=>type) pairs (type is a eT widget-type)
* );
