Events with procedures
To simplify the operations performed on widgets in a Dashboard control, several procedures are proposed in each event. These procedures take as parameter the widget variable to use. This variable is a Control variable. The widget can be handled by this variable.
Example: To find out which Widgets have been deleted by the user:
WINDEV 
PROCEDURE DeleteWidget(Widget is Control)
Trace("Deletion" + Widget.Caption)
Trace("Deletion" + Widget.SourceWindow)
WEBDEV - Código Servidor 
PROCEDURE DeleteWidget(Widget is Control)
Trace("Deletion" + Widget.Caption)
Trace("Deletion" + Widget.SourcePage)
AndroidiPhone/iPadMac Catalyst 
PROCEDURE DeleteWidget(Widget)
Trace("Deletion" + Widget.Caption)
Trace("Deletion" + Widget.SourceWindow)
Optional events
Several optional events can be added. 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.
    Note: Several optional events can be selected.
  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 deactivated code contains WLanguage code, this code is automatically deleted..
For example, you can use the following events:
  • 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.
Widget optional events
Widgets are internal windows displayed in a Dashboard control.
In this case, a specific optional event can be associated with the internal window or page: "Widget refresh"..
This event is executed when DashDisplay is run.
