since there are quite some people trying to build histogram
presenter apps using a control bar and a canvas, I take the
liberty of distributing a small sample program made by Robert
Loke (and cleaned up a little by me) doing exactly that.
The histograms are still empty but the whole can serve as
a good starting point. Take: ftp://hpsalo.cern.ch/pub/loke.tar.gz.
The Makefile is for HP-UX aCC. Just change it using
$ROOTSYS/test/Makefile as example for the desired platform.

you can place buttons on a canvas using TButton objects. See roottalk
digest where some examples are described. For the time being it is not
yet possible to change the canvas menubar pulldown menus. This will be
possible with the new version.
