add_action_widget

Description:

public void add_action_widget (Widget child, int response_id)

Adds an activatable widget to the action area of a `GtkDialog`.

Note:

Use [class@Gtk.Window] instead

GTK connects a signal handler that will emit the [signal@Gtk.Dialog:GtkDialog:response] signal on the dialog when the widget is activated. The widget is appended to the end of the dialog’s action area.

If you want to add a non-activatable widget, simply pack it into the action_area field of the `GtkDialog` struct.

Parameters:

this	a `GtkDialog`
child	an activatable widget
response_id	response ID for `child`
