file_activated

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 FileChooserDialog to know when to activate the default button in the dialog.
