[vtkusers] Problem with interaction in Tcl

[Roger Blum]

Hello vtk users,

I use vtk 5.0 with Tcl on Windows.

I have an application which uses multiple windows (each containing one or
more vtkTkRenderWidgets). The default behavior to grab the focus when the
mouse pointer enters the widget leads to a disturbing behavior: if the mouse
is moved out of the current window and enters an other vtkTkRenderWidget,
this one grabs the focus and brings it's window to the front (hiding the
current window).

Removing the focus command in the file binding.tcl solved the "wrong focus"
problem. But it seems to be a bad trick, as the vtkTkRenderWidget do not get
any key events anymore.
How can I avoid this behavior? What is the "correct" way to achieve what I
want (change of focus only on mouse click)?

Thanks for your help,
Roger
