the URI for the current folder. Free with glib.global.gfree. This function will also return null if the file chooser was unable to load the last folder that was requested from it; for example, as would be for calling gtk.file_chooser.FileChooser.setCurrentFolderUri on a nonexistent folder.
Gets the current folder of chooser as an URI. See gtk.file_chooser.FileChooser.setCurrentFolderUri.
Note that this is the folder that the file chooser is currently displaying (e.g. "file:///home/username/Documents"), which is not the same as the currently-selected folder if the chooser is in gtk.types.FileChooserAction.SelectFolder mode (e.g. "file:///home/username/Documents/selected-folder/". To get the currently-selected folder in that mode, use gtk.file_chooser.FileChooser.getUri as the usual way to get the selection.
