Processes associated with a Scheduler control
Events managed by default
WINDEV

Events supported by WINDEV and WINDEV Mobile

WINDEV and WINDEV Mobile manage the following events by default (order of appearance in the code editor):
EventRuntime condition
InitializingRun when the window is opened. *
Before creating the appointmentRun:
  • WINDEV when "New appointment" is selected in the context menu of Scheduler control.
  • during the direct input of a new appointment via the keyboard.
WINDEV Enter an appointment in input
Run:
  • when "New appointment" is selected in the context menu of Scheduler control.
  • during the direct input of a new appointment via the keyboard.
This event is run immediately after the event "Before creating the appointment".
WINDEV Exit from input for the appointment
Run when exiting the input of an appointment (e.g., exit when adding an appointment or when editing an appointment via the context menu)
Selecting an appointmentRun when an existing appointment is selected in the Scheduler control.
Moving an appointmentRun when an appointment is moved in the Scheduler control.
WINDEV This event is run at the end of the movement with the mouse (when the mouse is "released").
Remark: The move performed is canceled if this event runs the following line of code:
RESULT False
WINDEV Resizing an appointment
Run when resizing an appointment in the Scheduler control (resize operation performed with the mouse for example). This event is run at the end of the resize (when the mouse is "released").
WINDEV Deleting an appointment
Run:
  • when "Delete the appointment" is selected in the context menu of Scheduler control.
  • when an appointment is deleted via the DEL key of keyboard.
WINDEV Range selection
Run when selecting a time period in the Scheduler control (click performed on a time range for example). When several time ranges are selected with the mouse, the event is run for each new selected range.
Whenever changing period
WINDEV Run when modifying the period displayed in the Scheduler control (via the arrow buttons found at the top left of Scheduler control or when the period is changed through programming with SchedulerDisplayPreviousPeriod and SchedulerDisplayNextPeriod).
Reassigning an appointmentRun when moving an appointment triggers the modification of the resource associated with the appointment.
WINDEV Whenever changing the display mode
Run when the user changes the display mode of the Scheduler control. The new mode can be known in this event via SchedulerMode.

(*) By default, the "Initializing" event of each control is run according to the order in which the controls were created in the window. To modify this order of execution:
  1. On the "Ventana" tab, in the "Orden" group, click "Inicialización".
  2. In the window displayed, use the arrows on the right to modify the order in which the controls are initialized.
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 popup menu in an APT data file, simply write in the event "Exit from input for the appointment":
PROCEDURE ExitFromInput(aptEdited is Appointment)
 
// Store the data
APT.Title = aptEdited.Title
APT.StartDate = aptEdited.StartDate
APT.EndDate = aptEdited.EndDate
...
HAdd(APT)

Advanced use of events with procedure

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 event "Entry in edit in an appointment". To lock the direct input via the context menu of the scheduler, the event must return False.
WINDEV This principle can be applied to all the events called by the context menu of the Scheduler control.
WINDEV Example:
PROCEDURE Edit(aptEdited is Appointment)
 
// Opens the window for entering an appointment
// with the selected appointment (in Creation or Modification mode)
Open(WIN_InputAPT_HFSQL, aptEdited)
 
// Returns False to lock the direct input in the Scheduler control
RESULT False
Optional events
Several optional events are supported. Para añadir un evento opcional:
  1. Seleccione la control deseada.
  2. Mostrar la ventana del código de esta control (tecla F2).
  3. Haga clic en el enlace "Añadir otras Event s a xxx" en la parte inferior del código de la ventana, después de la última Event.
  4. Todos los eventos opcionales disponibles para el control se muestran.
  5. Marque la opción Event para agregar y validar.
    Observación: Puede seleccionar varios eventos opcionales.
  6. El Event opcional seleccionado se agrega automáticamente a los Event s administrados por el control.
Para desactivar un Event opcional, simplemente realice las mismas operaciones para mostrar la lista de Event s opcionales. A continuación, simplemente desmarque los eventos opcionales para eliminar.
Observación: Si el código desactivado contiene código WLanguage, este código se elimina automáticamente.
You can manage, for example:
  • the mouse hover over the control,
  • left mouse button down, up, with a double click,
  • right mouse button down, up, double click,
  • mouse wheel, etc.
For more details, see the Optional events.
