Properties

"connect-proxy": (arg0: Gtk.Action, arg1: Gtk.Widget) => void

The ::connect-proxy signal is emitted after connecting a proxy to an action in the group. Note that the proxy may have been connected to a different action before.

This is intended for simple customizations for which a custom action class would be too clumsy, e.g. showing tooltips for menuitems in the statusbar.

Gtk.UIManager proxies the signal and provides global notification just before any action is connected to a proxy, which is probably more convenient to use.

"disconnect-proxy": (arg0: Gtk.Action, arg1: Gtk.Widget) => void

The ::disconnect-proxy signal is emitted after disconnecting a proxy from an action in the group.

Gtk.UIManager proxies the signal and provides global notification just before any action is connected to a proxy, which is probably more convenient to use.

SignalDeprecatedpost-activate

"post-activate": (arg0: Gtk.Action) => void

The ::post-activate signal is emitted just after the action in the action_group is activated

This is intended for Gtk.UIManager to proxy the signal and provide global notification just after any action is activated.

"pre-activate": (arg0: Gtk.Action) => void

The ::pre-activate signal is emitted just before the action in the action_group is activated

This is intended for Gtk.UIManager to proxy the signal and provide global notification just before any action is activated.

notify: (arg0: GObject.ParamSpec) => void

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 GObject.ParamFlags.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 GObject.ParamFlags.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:

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][class@GObject.ParamSpec#parameter-names] as detail strings for the notify signal.
