Events supported in WEBDEV

The following events appear by default in the WEBDEV code editor:

Event	Runtime condition

Initialization (Server code)	Executed when the page is opened. Special case: automatically populated Combo Box controls based on a data file: When this code is executed, the Combo Box control is not populated yet. To force the control to be populated in this event, use: the ListDisplay function, the properties for manipulating Combo Box controls based on a data file: BrowsedFile, BrowsedItem or Filter.
End of initialization (Server code)	Code present only in automatically populated Combo Box controls based on a data file: Executed once the control has been populated. This code allows you to select, add or modify an element in the control.
Enter (Browser code)	Executed when the control gains focus.
Leave after changes (Browser code)	Executed when moving from one control to another (selecting another control with the mouse, etc.) after the content of the control was modified (selecting an element, for example).
Whenever modifying (Server code)	Executed when the user performs a selection.
Exit (Browser code)	Executed when moving from one control to another (selecting another control with the mouse, etc.).

Optional events

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

Select the desired 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.

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.
