Version 4 of A vertical-tab notebook

Updated 2003-07-11 13:28:59

set docu(VNotebook) { Richard Suchenwirth 2002-08-20 - This is a study in using the BWidgets toolkit, in particular using their PagesManager to implement a notebook with vertically-stacked tabs, by default to the right. The demo at end shows a usage example which may be used as a telephone booklet. As added goodie (if you have the code from An i15d date chooser and A little calculator available), the last page contains one of each - just to show that you can pack other things than text widgets. Enjoy! }

escargo 11 Jul 2003 - I saw this code had changed a little, and used my wish-reaper to download it. When I tried to get it to run, I had to define the environment variable BWIDGET_LIBRARY. After that, I discovered that, since I did not have the optional Calendar.tcl and sep_calc.tcl files, I had to modify the code not to source them. Finally, there seems to be no definition of docu(VNotebook). Is that supposed to be defined in some other context?
