The ::apply signal is emitted when the apply button is clicked.
The default behavior of the #GtkAssistant is to switch to the page
after the current page, unless the current page is the last one.
A handler for the ::apply signal should carry out the actions for
which the wizard has collected data. If the action takes a long time
to complete, you might consider putting a page of type
%GTK_ASSISTANT_PAGE_PROGRESS after the confirmation page and handle
this operation within the #GtkAssistant::prepare signal of the progress
page.
