Changeset 1065 for Scheduling/trunk/cs/bsdx0200GUISourceCode/CGDocumentManager.cs

Timestamp:

Jan 16, 2011, 5:32:40 AM (13 years ago)

Author:

Message:

CalendarGrid: Add MouseEnter event: puts focus on calendar grid. Used to "steal" focus from other controls so that lose focus events would fire.
CGDocumentManager: Added application-wide error handler on Application error exception; Added load timer to test how long it takes to load the GUI.
CGDocument: Just documentation updates.
