* @See_also:#GtkRecentChooser, #GtkRecentChooserDialog
|
|
*
|
|
* #GtkRecentChooserWidget is a widget suitable for selecting recently used
|
|
* files. It is the main building block of a #GtkRecentChooserDialog. Most
|
|
* applications will only need to use the latter; you can use
|
|
* #GtkRecentChooserWidget as part of a larger window if you have special needs.
|
|
*
|
|
* Note that #GtkRecentChooserWidget does not have any methods of its own.
|
|
* Instead, you should use the functions that work on a #GtkRecentChooser.
|
|
*
|
|
* Recently used files are supported since GTK+ 2.10.
