Events managed by default

Events managed by WINDEV and WINDEV Mobile

The following events are proposed by default (in order of appearance in the code editor):

Event	Runtime condition

Initialization	Run when opening the window. *
Versions 23 and later Click on a link New in version 23 Click on a link Click on a link	Run when clicking a link in the HTML control. Only external links (to another page) trigger this event. Internal links (to an anchor in the same page for example) do not trigger this event. This event accepts parameters. This event has the following format: PROCEDURE ClickLink(sLink) where <sLink> corresponds to an optional character string containing the URL of the link clicked in the HTML control. If this event returns False, the action associated with the link will not be performed.
Versions 23 and later End of load of HTML document New in version 23 End of load of HTML document End of load of HTML document	Run at the end of load of HTML document in the HTML control. If the user navigates using links in the HTML control, this event is run once each HTML document displayed in the control has been loaded.

(*) By default, the event "Initializing" of each control is run according to the order in which the controls were created in the window. To modify this runtime order:

On the "Window" pane, in the "Order" group, click "Initialization".
In the window that is displayed, use the arrows on the right to modify the initialization order of controls.

Optional events

Several optional events can be managed. To add an optional event:

Select the requested control.
Display the code window of this control (F2 key).
Click the link "Add other events to xxx" at the bottom of the window code, after the last event.
All the optional events available for the control are displayed.
Check the optional event to add and validate.
Remark: You can select several optional events.
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,
the left mouse button down, up, with a double click,
right mouse button down, up, with double click,
the mouse wheel, etc.
