ListBoxRowProtocol

public protocol ListBoxRowProtocol : ActionableProtocol

GtkListBoxRow is the kind of widget that can be added to a GtkListBox.

The ListBoxRowProtocol protocol exposes the methods and properties of an underlying GtkListBoxRow instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see ListBoxRow. Alternatively, use ListBoxRowRef as a lighweight, unowned reference if you already have an instance you just want to use.

    Note

    This represents the underlying activate signal

    Parameters

  • The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

    Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

    This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

    (C Language Example):

    g_signal_connect (text_view->buffer, "notify::paste-target-list",
                  G_CALLBACK (gtk_text_view_target_list_notify),
                  text_view)

    It is important to note that you must use canonical parameter names as detail strings for the notify signal.

    Note

    This represents the underlying notify::activatable signal

    Declaration

    Swift

ListBoxRow Class: ListBoxRowProtocol extension (methods and fields)

  • changed() Extension method

    Marks row as changed, causing any state that depends on this to be updated.

    This affects sorting, filtering and headers.

    Note that calls to this method must be in sync with the data used for the row functions. For instance, if the list is mirroring some external data set, and two rows changed in the external data set then when you call gtk_list_box_row_changed() on the first row the sort function must only read the new data for the first of the two changed rows, otherwise the resorting of the rows will be wrong.

    This generally means that if you don’t fully control the data model you have to duplicate the data that affects the listbox row functions into the row widgets themselves. Another alternative is to call [methodGtk.ListBox.invalidate_sort] on any model change, but that is more expensive.
