Events associated with windows
Events managed by default
WINDEV and WINDEV Mobile manage the following events by default (order of appearance in the code editor):
EventRuntime condition
Global declarationsDeclaring the variables global to the window. This is the first code run when opening the window.
End of initializationRun when the window is opened.
The events are run in the following order:
  • Initializing the window controls (*)
  • Initializing the window
  • Focus gain
Remark: A blinking effect may appear if the code for updating the controls is included in this event. Indeed, the initialization code of controls is run before the update code.
ClosingRun when closing the window.
Remarks:
  • Resuming the input in one of the window controls in this code prevents from closing the window.
  • If the window contains a "Cancel" Button, only the click code of this button is executed when the window is closed.
Versions 20 and later
Request for refreshing the display
New in version 20
Request for refreshing the display
Request for refreshing the display
Used to group the code for updating the window controls: content of controls, state (visible, grayed, etc.), caption to refresh, etc.
This event can receive parameters. Simply declare a procedure in the event. For example:
// Request for refreshing the display
PROCEDURE AskForRefresh(RefreshType is boolean)
This event is started upon request by the following functions:
When these functions are called, you can specify the value of the parameters expected by the event.
Versions 17 and later
Universal Windows 10 AppAndroid Change of orientation
New in version 17
Universal Windows 10 AppAndroid Change of orientation
Universal Windows 10 AppAndroid Change of orientation
Run when the user turns the screen around. This allows you to reposition the controls when changing the orientation of the screen.
Closing a child window of the windowRun when closing a child window opened from the current window.
You can:
  • use the Name property to get the name of the child window that was closed.
  • use the ReturnedValue property to get the return value of the child window.Example:
// -- Close a child window of WIN_OrderList
// Refreshes the list of orders if necessary
IF MyChildWindow.ReturnedValue = True THEN
OrderList()
END
The MyChildWindow keyword is used to manipulate the child window.
Versions 18 and later
Android Widget Refreshing the Widget
New in version 18
Android Widget Refreshing the Widget
Android Widget Refreshing the Widget
Used to update the Widget content. This event is run:
  • when opening a Widget window.
  • at regular time interval. This interval is defined in the "Details" tab of description window.
Remark: WidgetDisplay redisplays the Widget and runs the refresh event.

(*) 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 "Window" pane, in the "Order" group, click "Initialization".
  2. In the window displayed, use the arrows on the right to modify the order in which the controls are initialized.
Caution: If one or more controls use the persistence of controls, the "Whenever modified" code can be run when initializing the control. For more details, see Persistence of controls.
Optional events

Overview

Several optional events can be managed. 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 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, for example:
  • the mouse hover over the control,
  • left mouse button down, up, with a double click,
  • the right mouse button down, up, with double click,
  • the mouse wheel, etc.
