|
|
|
See lonhelper.pm documentation for discussion of the helper framework. |
|
|
|
Apache::lonprintout::page_size_state is an element that gives the |
|
user the opportunity to further refine the page settings if they |
|
select a single-column page. |
|
|
|
page_size_state is always directly invoked in lonprintout.pm, so there |
|
is no tag interface. You actually pass parameters to the constructor. |
