SignalDetailedRun Lastscript-SignalDetailedRun Lastscript-This signal is emitted when JavaScript in a web view calls
window.webkit.messageHandlers., after registering
webkit_user_content_manager_register_script_message_handler_with_reply()
The given reply can be used to send a return value with
webkit_script_message_reply_return_value() or an error message with
webkit_script_message_reply_return_error_message(). If none of them are
called, an automatic reply with an undefined value will be sent.
It is possible to handle the reply asynchronously, by simply calling
g_object_ref() on the reply and returning true.
SignalDetailedActionRun FirstnotifyThe 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.
