Details

tk2column() manipulate columns of a tk2mclistbox widget, tk2insert.multi() is used to insert multiple field entries in a tk2mclistbox widget, is.tk() determines if the tk package is loaded (on some platforms it is possible to load the tcltk package without tk, for instance, in batch mode). is.ttk() determines if 'ttk' widgets (styled widgets) used by the tk2XXX() functions are available (you need Tk >= 8.5).
