OperatorPage.on_first_hide()#

OperatorPage.on_first_hide()[source]#

Executed once, when the page is hidden for the first time, before executing on_each_hide().

Hook for code that is meant to be executed only once, when the page is hidden for the first time, before saving the page’s data.

Notes

Note the difference to on_close(), which is executed upon final submission of the page’s data. When using on_first_hide(), subject input can change (e.g., when a subject revists a page and changes his/her input).
