The following short block of code creates a menu bar with menu item "graphic"
disabled:
TopWindow <- tktoplevel(parent=.TkRoot)
TopMenu <- tkmenu(TopWindow)
tkconfigure(TopWindow,menu=TopMenu)
FileMenu <- tkmenu(TopMenu)
GraphicsMenu <- tkmenu(TopMenu)
tkadd(TopMenu,"cascade",label="File", menu=FileMenu)
tkadd(TopMenu,"cascade",label="Graphics", menu=GraphicsMenu, state="disabled")
Other than tkdestroy(TopMenu)and rebuilding the menubar
omitting'state="disabled"', is there a way to change the state of the menu item
"Graphics" to "normal"?
