### Arguments

`x` | A window object
`...` | Handled via `.Tcl.args`

### Details

`tkcmd` provides a generic interface to calling any Tk or Tcl command by simply running `.Tcl.args` on the arguments and passing the result to `.Tcl`. Most of the other commands simply call `tkcmd` with a particular first argument and sometimes also a second argument giving the subcommand.

`tktitle` and its assignment form provides an alternate interface to Tk's `wm title`

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 subcommands like `pack configure` are converted to function names like `tkpack.configure`.

### See Also

`TclInterface`, `TkWidgets`, `TkWidgetcmds`

### Examples

    ## 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(l1<-tklabel(tt,text="Heave"),l2<-tklabel(tt,text="Ho"))
    tkpack.configure(l1,side="left")

    ## Try stretching the window and then

    tkdestroy(tt)
