/**
|
|
* 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
|
|
* '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
|
|
* 'start' => // IO position in list
|
|
* '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
|
