31 * @brief Base class for option editing dialog boxes.
33 * Code to provided the basis for dialogs which allow the user to edit options
34 * from an ARDOUR::Configuration class.
36 * The idea is that we have an OptionEditor class which is the dialog box.
37 * This is essentially a GTK Notebook. OptionEditorComponent objects can
38 * then be added to the OptionEditor, and these components are arranged on
39 * the pages of the Notebook. There is also an OptionEditorComponent hierarchy
40 * here, providing things like boolean and combobox option components.
42 * It is intended that OptionEditor be subclassed to implement a particular
50 class OptionEditorPage;
