source: Scheduling/trunk/cs/bsdx0200GUISourceCode/CGDocumentManager.cs@ 1076

Last change on this file since 1076 was 1073, checked in by Sam Habiel, 14 years ago

calendarGrid: Removed MouseEnter event and added it to CGView which now has to handle it properly.
CGAppointments: now supports cloning.
CGDocument: Added RefreshDocumentAsync, which retrives data from the server w/o asking the grid to refersh.
CGDocumentManager: CGView.InitializeDocView does not take appointments as argument; callers are changed.
CGView: Many Changes:

  • Opening a Schedule nows calls up a splash and a wait cursor while loading.
  • Events coming from the server are now handled asynchronously (not on UI thread). This results in much better responsiveness.
  • Appointments, Availabilities, Resources are all set in the CalendarGrid by UpdateArrays; as a centralized point of drawing the grid.
  • A mistaken "feature"--stealing focus from each others windows, was removed--CalendarGrid.Focus event only fired now if the form is the Active Form. This is accomplished using GetActiveWindow() from user32.dll (a Win32 API).

LoadingSplash: Opacity removed; form resized.
