[R] How to use tcltk?

Hallo Tk experts,

the Tcl/Tk package allows to define very nice widgets for starting
R functions, for printing results and for interactive parameter input.
tkdensity.R and tkttest.R demonstrate this and both demos explain
how some of the tk functions can be used.
For constructing new widgets I would like to see further examples
showing Tcl/Tk package in action. Therefore my question:
Is there a pool of well designed applications of tk functions? /
Have you created a beautiful example?

Here is one of my problems: To print the position of the mouse cursor
the following lines of code will work:

  label .l2 -textvariable tvar
  pack  .l2
  bind  .    <Motion> { set tvar "position %x %y" }
  bind  .    <Leave>  { set tvar "mouse outside"  }

However, I have not been able to implement this by tk* functions of the R
package. Any idea?
