The #GtkFileChooserButton is a widget that lets the user select a file. It implements the #GtkFileChooser interface. Visually, it is a file name with a button to bring up a #GtkFileChooserDialog. The user can then use that dialog to change the file associated with that button. This widget does not support setting the #GtkFileChooser:select-multiple property to true.
