SignalListItemFactorySignalName

Emitted when a new [propertyGtk.ListItem:item] has been set on the listitem and should be bound for use.

After this signal was emitted, the listitem might be shown in a [classGtk.ListView] or other list widget.

The [signalGtk.SignalListItemFactory::unbind] signal is the opposite of this signal and can be used to undo everything done in this signal.

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.

Emitted when a new listitem has been created and needs to be setup for use.

It is the first signal emitted for every listitem.

The [signalGtk.SignalListItemFactory::teardown] signal is the opposite of this signal and can be used to undo everything done in this signal.

Emitted when a listitem is about to be destroyed.

It is the last signal ever emitted for this listitem.

This signal is the opposite of the [signalGtk.SignalListItemFactory::setup] signal and should be used to undo everything done in that signal.

Emitted when a listitem has been removed from use in a list widget and its new [propertyGtk.ListItem:item] is about to be unset.

This signal is the opposite of the [signalGtk.SignalListItemFactory::bind] signal and should be used to undo everything done in that signal.
