[vtkusers] vtkCanvas keyPress events

[Jeff Lee]

in short, you could override the behavior of the existing keylistener 
something like 
public void keyPressed(KeyEvent e) {

    char keyChar = e.getKeyChar();

    if ('.' == keyChar)
      {
        doMyNeatThing();
        return;
      }
... rest of default implementation in vtkCanvas.keyPressed()...
}

long term solution would be to add a user method so you can just 
register a pair<char, action>.  I can put something like this in the 
code, but I really meant vtkCanvas/vtkPanel to be more of an example 
than something used for production code - mainly because I haven't heard 
of armies of developers using it.  Also because there are too many 
things going on inside of vtkPanel/Canvas that really should be busted 
out into other classes - more of a toolkit.
