## Description

GtkRecentChooser is an interface that can be implemented by widgets displaying the list of recently used files. In GTK+, the main objects that implement this interface are GtkRecentChooserWidget, GtkRecentChooserDialog and GtkRecentChooserMenu.

Recently used files are supported since GTK+ 2.10.

Default value: -1

This signal is emitted when the user "activates" a recent item in the recent chooser. This can happen by double-clicking on an item in the recently used resources list, or by pressing Enter.

`chooser` : | the object which received the signal
`user_data` : | user data set when the signal handler was connected.

Since 2.10

### The `"selection-changed"` signal
