Gtk.FileChooser::file-activated

function callback(file_chooser, ):void;

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 <keycap>Enter</keycap>.

Normally you do not need to connect to this signal. It is used internally by Gtk.FileChooserDialog to know when to activate the default button in the dialog.
