Signal

GtkSectionModel::sections-changed

since: 4.12

Declaration

void
sections_changed (
  GtkSectionModel* self,
  guint position,
  guint n_items,
  gpointer user_data
)

Description [src]

Emitted when the start-of-section state of some of the items in model changes.

Note that this signal does not specify the new section state of the items, they need to be queried manually. It is also not necessary for a model to change the section state of any of the items in the section model, though it would be rather useless to emit such a signal.

The GListModel::items-changed implies the effect of the GtkSectionModel::sections-changed signal for all the items it covers.

Default handler:

The default handler is called after the handlers added via g_signal_connect().

Available since: 4.12

Parameters

position

Type: guint

The first item that may have changed.

n_items

Type: guint

Number of items with changes.
