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