/* MZCrumbBar.cpp MZCrumbBar Ctrl - Created by Mathias Svensson (C) Copyright 2009-2010 - ( http://result42.com/projects/MZCrumbBar ) History v1.2 2010-04-15 Added improvments/fixes provided by Iain Clarke * 3 more BuildCrumbbar(...) function for special situations. * Refactored how a path is parsed. * Added CRU_LASTITEMNODELIMITER. If style is set the Delimiter will not be shown for last crumbbar item. * Style can now be set using styleEx. * Change Default hot color to COLOR_HOTLIGHT * Added possibility to store custom data in a Crumbar item. * Added SetItemData/GetItemData of custom data to crumbbar items. Fixed so that if double delimiter now works again. Double delimiter should be part of the crumbpath name, not a splitter. Change so that items are added to m_vCrumbItems via the virtual function AddCrumbItem(...) Fixed so that empty path parts are not added to the path. v1.1 2010-03-17 First Public Version, Fixed minor draw issue v1.0 2009-10-10 First Version All rights reserved.
