This seems like a dubious approach. nullTree is a subclass of leoTree.
leoTree.redraw_after_head_changed is simply self.c.redraw(). c.redraw is::
def redraw (self,p=None,setFocus=False):
c = self
if p:
# Update body pane and set c._currentPosition.
c.expandAllAncestors(p) # Redundant, but safe.
c.selectPosition(p)
else:
p = c.currentPosition()
c.expandAllAncestors(p)
c.frame.tree.redraw(p)
if setFocus: c.treeFocusHelper()
True, this does call c.frame.tree.redraw, but c.frame.tree is a nullTree,
and nullTree.redraw is simply a pass.
So my guess is that the problem occurs in c.redraw before calling
c.frame.tree.redraw. Your proposed solution guts, in effect, all the code
in c.redraw. That does not seem like a good idea to me.
