43 /*
44 Notes:
45 - We do not look at LAYOUT_FIX_WIDTH and LAYOUT_FIX_HEIGHT because
46 FXSwitcher resizes its children anyway and doing this would cause
47 the size to grow instead of shrinkwrap to the biggest child.
48 - Thanks to Charles Warren for the suggestion for the collapse
49 modes.
50 - The current panel number is adjusted if the number of panels changes.
