// wxPropertySheetDialog
// A platform-independent properties dialog.
//
//   * on PocketPC, a flat-look 'property sheet' notebook will be used, with
//     no OK/Cancel/Help buttons
//   * on other platforms, a normal notebook will be used, with standard buttons
//
// To use this class, call Create from your derived class.
// Then create pages and add to the book control. Finally call CreateButtons and
// LayoutDialog.
//
// For example:
//
// MyPropertySheetDialog::Create(...)
// {
//     wxPropertySheetDialog::Create(...);
//
//     // Add page
//     wxPanel* panel = new wxPanel(GetBookCtrl(), ...);
//     GetBookCtrl()->AddPage(panel, wxT("General"));
//
//     CreateButtons();
//     LayoutDialog();
// }
//
// Override CreateBookCtrl and AddBookCtrl to create and add a different
// kind of book control.
