Tk non-widget commands

Description

These functions interface to Tk non-widget commands, such as the window manager interface commands and the geometry managers.

tkcmd(...) # same as tcl(), for compatibility
tktitle(x)

tktitle(x) <- value

tkbind(...)
tkbindtags(...)
tkfocus(...)
tklower(...)

tkXselection.clear(...)
tkXselection.get(...)
tkXselection.handle(...)
tkXselection.own(...)

tkwait.variable(...)
tkwait.visibility(...)
tkwait.window(...)

## winfo actually has a large number of subcommands, but it's rarely
## used, so use tkwinfo("atom", ...) etc. instead.

Arguments

Details

tcl provides a generic interface to calling any Tk or Tcl command by simply running .Tcl.args.objv on the argument list and passing the result to .Tcl.objv. Most of the other commands simply call tcl with a particular first argument and sometimes also a second argument giving the subcommand. Prior to R 2.0.0, this function was called tkcmd, which will still work but will be deprecated in a later version. Also, the file commands used to be tkopen, tkclose, etc., but since open and close do not belong to the Tk toolkit, the preferred names are now tclopen, etc. Again, the old names are temporarily preserved for compatibility.

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. With a few exceptions, the pattern is that Tk subcommands like pack configure are converted to function names like tkpack.configure, and Tcl subcommands are like tclfile.dir.

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

## Try stretching the window and then

tkdestroy(tt)
## End(Not run)
