Class: NavigationHistory (in Tools)


Inheritance:

   Object
   |
   +--Tools::NavigationHistory

Package:
stx:libtool
Category:
Interface-Browsers-New-History
Version:
rev: 1.20 date: 2017/03/29 11:05:31
user: stefan
file: Tools__NavigationHistory.st directory: libtool
module: stx stc-classLibrary: libtool

Description:


two variants:
    a forward-backward history, as in a browser:
        navigating backward moves a pointer in a list
    a global history
        navigating moves the navigated item to the front position

hack: configurable to behave either as a global history
      or as a local-tab navigation history.
Also implement backward compatible list-style access interface,
to support old browsers (I guess, this is temporary and the other 
users of the global history (debugger, old systembrowser etc. should
be changed)
