Changeset 1106 for Scheduling/trunk/cs/bsdx0200GUISourceCode

Timestamp:

Mar 20, 2011, 3:22:11 AM (14 years ago)

Author:

Sam Habiel

Message:

CalendarGrid:

• Support for Autoscrolling corrected.
• A little optimization: Grid is only drawn once now when starting, not twice (don't know why original code did that).

CGAppointment:

• Added member Patient (new Class)

CGDocument:

• OnOpenDocument now accepts input of DateTime to decide where to open document.
• SlotsAvailable algorithm now includes code for scaling according to timescale and code to merge Blocks if they are adjacent.

CGDocumentManager:

• Fix bug having to do with canceling log-in after first retry. BMX lib threw an exception which was not caught.

CGView: Many changes:

• SlotsAvailable signature changed in CGDocument. All references to it had to be changed.
• Opening a node in the tvSchedules by clicking on the plus sign did not select it. Code changes to make it select it.
• UpdateStatusBar now uses a string builder; and shows a more comprehensive message on the availability in the Status Bar.
• Focus issues on various controls.
• Support for printing a slip after an appointment is made automatically has been added.

CustomPrinting:

• now includes a method to print a single appointment slip

DAppointPage:

• Checkbox to decide whether to print appt slip added.
• New readonly property to get the appointment that has been made (of type CGAppointment).

DApptSearch:

• StartDate and EndDate now autoadjust based on each other.
• lblMessage added to show user message if no appointments are found.
