		\brief The PaletteViewer class provides an object to view and manage palette view.

		Inherits \b QWidget.

		This object allows to show and manage palette; it's possible distinguish three

		view type, class can show: current level palette, current studio palette or

		current cleanup palette, using setPalette() to set palette viewer.

		The object is composed of a vertical layout with three widget:

		\li a tab bar \b PaletteViewerGUI::TabBar in which are displayed palette page

		\b createTabBar();

		\li a central frame \b PaletteViewerGUI::PageViewer in which are displayed

		all style of current page in palette

		\li a button bar, \b createToolBar(), \b createPaletteToolBar()

		and \b createSavePaletteToolBar();

		A collection of method allows you to manage this object and its interaction

		with palette.
