Events with procedures
To handle appointments in a scheduler more easily, several procedures appear in each event. These procedures take the appointment variable (Appointment variable) as parameter. All the details of the appointment handled by the context menu are automatically assigned to this variable.
Example: To store an appointment added by the user via the context menu in an APT data file, simply write in the "Exit from input for the appointment" event:
PROCÉDURE ExitFromInput(aptEdited is Appointment)
// Store the data
APT.Title = aptEdited.Title
APT.StartDate = aptEdited.StartDate
APT.EndDate = aptEdited.EndDate

Advanced use of events with procedures

You can also allow the user to define more precisely the characteristics of his appointment during an addition or a modification. To do so, you must create a window or a page with the information to fill.
In the code, simply open the window or page in the "Entry in edit in an appointment" event. To lock the direct input via the context menu of the scheduler, the event must return False.
Optional events
Several optional events are supported. To add an optional event:
  1. Select the desired control.
  2. Display the code window of this control (F2 key).
  3. Click the link "Add other events to xxx" at the bottom of the window code, after the last event.
  4. All the optional events available for the control are displayed.
  5. Check the optional event to add and validate.
    Remark: You can select several optional events.
  6. The selected optional event is automatically added to the events managed by the control.
To disable an optional event, simply perform the same operations to display the list of optional events. Then simply uncheck the optional events to delete.
Remark: If the disabled code contains WLanguage code, this code is automatically deleted.
You can manage the following aspects, for example:
  • the mouse hover over the control,
  • left mouse button down, up, double click,
  • right mouse button down, up, double click,
  • mouse wheel, etc.
For more details, see the Optional events.
