00041 * The Switcher layout manager automatically arranges its child
00042 * windows such that one of them is placed on top; all other
00043 * child windows are hidden.
00044 * Switcher provides a convenient method to conserve screen
00045 * real-estate by arranging several GUI panels to appear in the
00046 * same space, depending on context.
00047 * Switcher ignores all layout hints from its children:- all
00048 * children are stretched according to the switcher layout
00049 * managers own size.
00050 * When the SWITCHER_HCOLLAPSE or SWITCHER_VCOLLAPSE options
00051 * are used, Switcher's default size is based on the width or
00052 * height of the current child, instead of the maximum width
00053 * or height of all of the children.
