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