I use libpoppler-glib8 version 22.12.0-2+b1 on Debian Bookworm to read the structure of PDF documents and to extract some components from them. However, I could not find a way to actually access trigger events e.g. from forms.
E.g. the attached PDF file has a form field which calls simple JavaScript functions for the focus in and out events and for input validation. I tried the following: * The list returned by `poppler_page_get_link_mapping()` does not contain any `POPPLER_ACTION_JAVASCRIPT` items. * The list returned by `poppler_page_get_annot_mapping()` contains only a `POPPLER_ANNOT_WIDGET` (20) item, for which no corresponding `PopplerAnnot*` structure is defined – no idea what I should do with it. * The form element, contained in the list returned by `poppler_page_get_form_field_mapping()`, does not have an associated `PopplerAction` (i.e. `poppler_form_field_get_action() == NULL`). Only `poppler_form_field_get_additional_action(item, POPPLER_ADDITIONAL_ACTION_VALIDATE_FIELD)` properly returns a `PopplerActionJavascript`, containing the correct script. Unfortunately, I have no idea how I can access the actions related to the focus in and out events (and probably all others defined in PDF 32000-1:2008, section 12.6.3 “Trigger Events”). Any insight will be highly appreciated! Thanks in advance, Albrecht.
