Where can I find more infomation on FormLayout(s) and FormBuilder(s)? In particular, information about the preference and size properties like the ones in the below eamples? ie. <"leftref, 5dlu, pref:grow"> and <"colSpec=2cm">
FormLayout layout = new FormLayout("left:pref, 5dlu, pref:grow");
is this notation some standard API that I can find other resources of information about or are they particular to SpringRPC?
