Arguments:

  widget: The widget this applies to

     ...: Handled via '.Tcl.args'

Details:

     There are far too many of these commands to describe them and
     their arguments in full. Please refer to the Tcl/Tk documentation
     for details. Except for a few exceptions, the pattern is that  Tcl
     widget commands possibly with subcommands like '.a.b selection
     clear' are converted to function names like 'tkselection.clear'
     and the widget is given as the first argument.

Examples:

     ## Not run: 
     ## These cannot be run by examples() but should be OK when pasted
     ## into an interactive R session with the tcltk package loaded

     tt <- tktoplevel()
     tkpack(txt.w <- tktext(tt))
     tkinsert(txt.w, "0.0", "plot(1:10)")

     # callback function 
     eval.txt <- function()
        eval(parse(text=tclvalue(tkget(txt.w, "0.0", "end"))))
     tkpack(but.w <- tkbutton(tt,text="Submit", command=eval.txt))

     ## Try pressing the button, edit the text and when finished:

     tkdestroy(tt)
     ## End(Not run)
