- // ==========================================================================
- // HISTORY:
- // ==========================================================================
- // 1.01 13 Aug 1998 - Andrew Bancroft [ABancroft@lgc.com] - Since we've already
- // added the entire toolbar to the imagelist we need to
- // increment nNextImage even if we didn't add this button to
- // m_mapIDtoImage in the LoadToolbar() method.
- // 1.01a 13 Aug 1998 - Peter Tewkesbury - Added AddSingleBitmap(...)
- // method for adding a single bitmap to a pulldown
- // menu item.
- // 1.02 13 Aug 1998 - Omar L Francisco - Fixed bug with lpds->CtlType
- // and lpds->itemData item checking.
- // 1.03 12 Nov 1998 - Fixes debug assert in system menu. - Wang Jun
- // 1.04 17 Nov 1998 - Fixes debug assert when you maximize a view - Wang Jun
- // window, then try to use the system menu for the view.
- // 1.05 09 Jan 1998 - Seain B. Conover [sc@tarasoft.com] - Fix for virtual
- // key names.
- // 1.06 24 Feb 1999 - Michael Lange [michael.home@topdogg.com] - Fix for memory
- // leak in CMyItemData structure, added a destructor that
- // calls text.Empty().
- // - Boris Kartamishev [kbv@omegasoftware.com] - Fix for resource
- // ID bug.
- // - Jeremy Horgan [jeremyhorgan@hotmail.com] - During
- // accelerator key processing OnInitMenuPopup() calls
- // ConvertMenu() which allocates a new CMyItemData for each
- // menu item. This is memory is normally freed by a call to
- // OnMenuSelect(), which is not called when processing
- // accelerator keys. This results in a memory leak. This was
- // fixed by modifying the ~CCoolMenuManager() destructor.
- // 1.07 24 Feb 1999 - Koji MATSUNAMI [kmatsu@inse.co.jp] - Fixed problem with
- // popup menus being drawn correctly as cool menus.
