Hi people,

I've a window who draws a view. This view has the same size as the
window and contains a model with a lot of graphical objects. The time
to render this view is considerable...

Then, I want to draw some "dynamic" graphical object over this view.
This new "dynamic" objects can change with the mouse position.. So I
need to do some redraws.
Use only one view and model is not a good idea because the dynamic
objects change for each mouse movement and the time to render the view
is too much. So, the interaction sucks...

If I separate the static and dynamic objects with 2 models and views
and I only redraw the dynamic objects contained in the 2nd model, the
"dynamic" view hides the static view beacuse has the same dimensions.

Then how can I do to separate this to create a good interaction
redrawing only the "dynamic" objects.

Any suggestion.
Thanks,
llo
