Events managed by WINDEV and WINDEV Mobile

WINDEV and WINDEV Mobile manage the following events by default (in order of appearance in the code editor):
EventRuntime condition
InitializingRun when opening the window. *
Before creating the appointmentRun:
  • WINDEV when "New appointment" is selected from the popup 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 from the popup 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 during the exit from appointment input (exit when adding an appointment or when modifying an appointment via the popup menu for example).
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").
Versions 22 and later
Note: The move performed is canceled if this event runs the following code line:
RESULT False
New in version 22
Note: The move performed is canceled if this event runs the following code line:
RESULT False
Note: The move performed is canceled if this event runs the following code line:
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 from the popup menu of Scheduler control.
  • when an appointment is deleted via the DEL key of keyboard.
WINDEV Selecting a period
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 by programming with SchedulerDisplayPreviousPeriod and SchedulerDisplayNextPeriod).
Reassigning an appointmentRun when moving an appointment triggers the modification of the resource associated with the appointment.
Versions 17 and later
WINDEV Whenever changing the display mode
New in version 17
WINDEV Whenever changing the display mode
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 runtime order:
  1. Select "Windows .. Edit the initialization order".On the "Window" pane, in the "Order" group, click "Initialization".
  2. In the window that is displayed, use the arrows on the right to modify the initialization order of controls.
Events with procedures
To simplify the operations performed on the appointments in a scheduler, several procedures are proposed in each event. These procedures take the Appointment variable as parameter. All the details of the appointment handled by the popup 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 popup menu of the scheduler, the event must return False.
WINDEV This principle can be applied to all the events called by the popup 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 can be managed.
To manage an optional event, simply select it in the icon bar of the code window.
In WINDEV:
In WEBDEV:
In WINDEV Mobile:
To add an optional event:
  1. Select the requested control.
  2. Display the code window of this control (F2 key).
  3. Click the link "Add other processes to xxx" at the bottom of the window code, after the last event.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.
    Note: 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.
Note: If the disabled code contains WLanguage code, this code is automatically deleted.
You can manage, for example:
  • the control rollover with the mouse,
  • the left mouse button down, up, with a double click,
  • the right mouse button down, up, with double click,
  • the mouse wheel, ...
See Optional events for more details.
