Hello Peter,

assuming gpane is the graphics-pane containing your tree-view, try:

(capi::build-graph (capi::graph-pane-layout gpane)
(capi::force-redisplay gpane)

for ease of use in getting my hands on the graphics pane in my interface, I
add an :accessor name in my interface definition
(capi:define-interface graph-it ()
....
  (:layouts
     (grapher capi:graph-pane
           :accessor grapher
         ...
  )))

then you can use (grapher intf) to easily access the tree view.

HTH,

Raymond Laning

Hi,

I am trying to redisplay a tree-view after setting a value that should
change how deep it expands the tree.

I have tried capi:redisplay-collection-item. It doesn't seem to do
anything,
and furthermore, I don't have the tree-view (collection object) handy when
the callback adjusting the expand depth is executed. I have tried
capi:redisplay-interface. It doesn't seem to do anything either.

I must be missing something simple, but looking for examples in some code I

had written a few years ago, I see that I couldn't do it then either!
