Assistant
GtkAssistant is used to represent a complex as a series of steps.
Each step consists of one or more pages. GtkAssistant guides the user through the pages, and controls the page flow to collect the data needed for the operation.
GtkAssistant handles which buttons to show and to make sensitive based on page sequence knowledge and the enum@Gtk.AssistantPageType of each page in addition to state information like the completed and committed page statuses.
If you have a case that doesn’t quite fit in GtkAssistants way of handling buttons, you can use the %GTK_ASSISTANT_PAGE_CUSTOM page type and handle buttons yourself.
GtkAssistant maintains a GtkAssistantPage object for each added child, which holds additional per-child properties. You obtain the GtkAssistantPage for a child with method@Gtk.Assistant.get_page.
GtkAssistant as GtkBuildable
The GtkAssistant implementation of the GtkBuildable interface exposes the @action_area as internal children with the name “action_area”.
To add pages to an assistant in GtkBuilder, simply add it as a child to the GtkAssistant object. If you need to set per-object properties, create a GtkAssistantPage object explicitly, and set the child widget as a property on it.
