gtk:file-dialog-default-filter (object)

object -- a gtk:file-dialog object
filter -- a gtk:file-filter object

The accessor for the default-filter slot of the gtk:file-dialog class gets or sets the filter that will be selected by default in the file chooser dialog.

If set to nil, the first item in filters will be used as the default filter. If that list is empty, the dialog will be unfiltered.
