Properties

"extension-added": (arg0: Peas.PluginInfo, arg1: GObject.Object) => void

Emitted when a new extension has been added to the Peas.ExtensionSet.

It happens when a new plugin implementing the extension set's extension type is loaded.

You should connect to this signal in order to set up the extensions when they are loaded. Note that this signal is not fired for extensions coming from plugins that were already loaded when the Peas.ExtensionSet instance was created. You should set those up by yourself.

"extension-removed": (arg0: Peas.PluginInfo, arg1: GObject.Object) => void

Emitted when a new extension is about to be removed from the Peas.ExtensionSet.

It happens when a plugin implementing the extension set's extension type is unloaded, or when the Peas.ExtensionSet itself is destroyed.

You should connect to this signal in order to clean up the extensions when their plugin is unload. Note that this signal is not fired for the GObject.Object instances still available when the Peas.ExtensionSet instance is destroyed. You should clean those up by yourself.

Properties - Inherited from GObject

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.
