2333: # Routines to display form items in a multi-row table with 2 columns.
2334: # Uses nested tables to divide form elements into segments.
2335: # For examples of use see loncom/interface/lonnotify.pm
2336: #
2337: # Can be used in following order: ...
2338: # &start_pick_box()
2339: # row1
2340: # row2
2341: # row3 ... etc.
2342: # &submit_row()
2343: # &end_pick_box()
2344: #
2345: # where row1, row 2 etc. are chosen from &role_select_row,&course_select_row,
2346: # &status_select_row and &email_default_row
2347: #
2348: # Can also be used in following order:
2349: #
2350: # &start_pick_box()
2351: # &row_title()

2353: # &row_title()
2354: # &row_closure() ... etc.
2355: # &submit_row()
2356: # &end_pick_box()
2357: #
2358: # In general a &submit_row() call should proceed the call to &end_pick_box(),
2359: # as this routine adds a button for form submission.
2360: # &submit_row() does not require a &row_closure after it.
2361: #
2362: # &start_pick_box() creates a bounding table with 1-pixel wide black border.
2363: # rows should be placed between calls to &start_pick_box() and &end_pick_box.
2364: #
2365: # &row_title() adds a title in the left column for each segment.
2366: # &row_closure() closes a row with a 1-pixel wide black line.
2367: #
2368: # &role_select_row() provides a select box from which to choose 1 or more roles
2369: # &course_select_row provides ways of picking groups of courses
2370: # radio buttons: all, by category or by picking from a course picker pop-up
2371: # note: by category option is only displayed if a domain has implemented
2372: # selection by year, semester, department, number etc.
2373: #
2374: # &status_select_row() provides a select box from which to choose 1 or more
2375: # access types (current access, prior access, and future access)
2376: #
2377: # &email_default_row() provides text boxes for default e-mail suffixes for
2378: # different authentication types in a domain.
2379: #
