Description
I found that the sub-tabbedPane can not have a title, the test code is shown as follows:
import groovy.swing.* def swing = new SwingBuilder() def frame = swing.frame() { tabbedPane() { label(text:'a', title:'ta') tabbedPane() { label(text:'sa', title:'sta') // the title named sta does not show :( label(text:'sb', title:'stb') // the title named stb does not show, too :( } } } frame.pack() frame.show()
