This signal is emitted when the user "activates" a file in the file
chooser. This can happen by double-clicking on a file in the file list, or
by pressing Enter.
Normally you do not need to connect to this signal. It is used internally
by #GtkFileChooserDialog to know when to activate the default button in the
dialog.
