[vtkusers] focus with tcl/tk and vtkRenderWindow

[Odet Christophe]

Hi David,

In order to overcome this problem I use a tk binding on the window TkRendeWindow containing it
for all the keypress. Two lines seem to work well:

  vtkTkRenderWidget .${name}.c.rw -rw ${name}_renWin -width $width -height $height
# This 2 lines for getting keypress in the natural vtkinteractor and forbidding e (for exit)
  bind .${name}.c.rw <KeyPress> "if {\[string first %A \"eE\"] == -1} {
     [${name}_iren GetInteractorStyle] OnChar 0 0 %A 0 } "
  bind .${name}.c.rw <Enter> "focus .${name}.c.rw "

All the fonctionnalities are available.
I hope this will help.

Christophe
