00040 * The Switcher layout manager automatically arranges its child

00042 * child windows are hidden.
00043 * Switcher provides a convenient method to conserve screen
00044 * real-estate by arranging several GUI panels to appear in the
00045 * same space, depending on context.
00046 * Switcher ignores all layout hints from its children:- all
00047 * children are stretched according to the switcher layout
00048 * managers own size.
00049 * When the SWITCHER_HCOLLAPSE or SWITCHER_VCOLLAPSE options
00050 * are used, Switcher's default size is based on the width or
00051 * height of the current child, instead of the maximum width
00052 * or height of all of the children.
