notify

Properties

close: () => void

This signal is emitted when the save delegate should close the widget it is related to. This can happen after saving as part of a close request and it is now save for the delegate to close.

Implementations are encouraged to connect to this signal (or implement the virtual method) and call panel_widget_force_close().

discard: () => void

This signal is emitted when the user has requested that the delegate discard the changes instead of saving them.

Implementations are encouraged to connect to this signal (or implement the virtual method) and revert the document to the last saved state and/or close the document.

"notify::icon-name": (pspec: GObject.ParamSpec) => void
"notify::is-draft": (pspec: GObject.ParamSpec) => void
"notify::progress": (pspec: GObject.ParamSpec) => void
"notify::subtitle": (pspec: GObject.ParamSpec) => void
"notify::title": (pspec: GObject.ParamSpec) => void
save: (arg0: Gio.Task) => boolean | void

This signal can be used when subclassing Panel.SaveDelegate is not possible or cumbersome. The default implementation of Panel.SaveDelegateClass.save_async() will emit this signal to allow the consumer to implement asynchronous save in a flexible manner.

The caller is expected to complete task with a boolean when the save operation has completed.

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.
