[vtkusers] Trying to use vtkChartXY with Tcl

[David Gobbi]

Hi Mario,

The fact that you are using Tcl actually validates our continuing
support for Tcl, so in a way it is a good thing.

The best way to get a fully-functional VTK window with Tcl is to
use Tk.  Take a look at these two examples:

  Examples/GUI/Tcl/vtkTkRenderWidgetDemo.tcl
  Examples/GUI/Tcl/MaceTk.tcl

The MaceTk example provides a window close operation, using
this call to the window manager:

  wm protocol . WM_DELETE_WINDOW <callback function>

For more information, see the tk documentation, e.g.:
https://www.tcl.tk/man/tcl8.4/TkCmd/wm.htm
