2194: # Nested table routines.
2195: #
2196: # Routines to display form items in a multi-row table with 2 columns.
2197: # Uses nested tables to divide form elements into segments.
2198: # For examples of use see loncom/interface/lonnotify.pm
2199: #
2200: # Can be used in following order: ...
2201: # &start_pick_box()
2202: # row1
2203: # row2
2204: # row3 ... etc.
2205: # &submit_row()
2206: # &end_pick_box()
2207: #
2208: # where row1, row 2 etc. are chosen from &role_select_row,&course_select_row,
2209: # &status_select_row and &email_default_row
2210: #
2211: # Can also be used in following order:
2212: #
2213: # &start_pick_box()
2214: # &row_title()
2215: # &row_closure()
2216: # &row_title()
2217: # &row_closure() ... etc.
2218: # &submit_row()
2219: # &end_pick_box()
2220: #
2221: # In general a &submit_row() call should proceed the call to &end_pick_box(),
2222: # as this routine adds a button for form submission.
2223: # &submit_row() does not require a &row_closure after it.
2224: #
2225: # &start_pick_box() creates a bounding table with 1-pixel wide black border.
2226: # rows should be placed between calls to &start_pick_box() and &end_pick_box.
2227: #
2228: # &row_title() adds a title in the left column for each segment.
2229: # &row_closure() closes a row with a 1-pixel wide black line.
2230: #
2231: # &role_select_row() provides a select box from which to choose 1 or more roles
2232: # &course_select_row provides ways of picking groups of courses
2233: # radio buttons: all, by category or by picking from a course picker pop-up
2234: # note: by category option is only displayed if a domain has implemented
2235: # selection by year, semester, department, number etc.
2236: #
2237: # &status_select_row() provides a select box from which to choose 1 or more
2238: # access types (current access, prior access, and future access)
2239: #
2240: # &email_default_row() provides text boxes for default e-mail suffixes for
2241: # different authentication types in a domain.
2242: #
2243: # &row_title() and &row_closure() are called internally by the &*_select_row
