public final boolean isAutoSizeChildren ()

taken from field

Controls whether or not this Group will automatically resize any managed resizable children to their preferred sizes during the layout pass. If set to false, then the application is responsible for setting the size of this Group's resizable children, otherwise such nodes may end up with a zero width/height and will not be visible. This variable has no effect on content nodes which are not resizable (Shape, Text, etc).
