32 * @short_description: A widget to create a guided installation
35 * #ModestWizardDialog is a widget to create a guided installation
36 * process. The dialog has four standard buttons, previous, next,
37 * finish, cancel, and contains several pages with optional icons.
38 * Response buttons are dimmed/undimmed automatically and the standard
39 * icon is shown/hidden in response to page navigation. The notebook
40 * widget provided by users contains the actual wizard pages.
