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.
