I'm already on the way ... almost working, but need further debugging. After that, guess my last change will be to make Abdel happy and confine the nice-scrolling behaviour within the BufferView class, so to avoid too many changes to TextMetrics (and the ParMetricsCache class).
On a related note, in order to call a method when the GUI is "idle", I'm using the QTimer::singleShot() method, with a delta_time of 0. Do you think that would turn to be useful for other things as well ? I mean, something like GuiView::doWhenIdle(this, &myMethod): template<class T> static GuiView::doWhenIdle(T *, bool (T::*)(void)) (with something like myMethod() returning true or false meaning call me again or not). Any drawbacks with such an approach (I know there is a support/timer.h class, but guess it cannot know when the GUI is idle). T.
