Events associated with List Box controls

Events managed by default

WINDEV and WINDEV Mobile manage the following events by default (order of appearance in the code editor):

Event	Runtime condition

Initialization	Run when the window is opened. (*) Special case: Browsing List Box automatically filled: When this code is run, the List Box control is not filled yet. To force the List Box control to be filled in this code, use: ListDisplay. the properties for managing browsing List Box controls: BrowsedFile, BrowsedItem or Filter.
End of initialization	Code only for browsing List Box controls filled automatically: Run once the List Box control has been filled. This code allows you to select, add or modify an element in the List Box control.
Entry	Run when the control takes focus
Exit	Run when moving from one control to another (TAB key, selecting another control with the mouse, etc.).
Selecting a row	Run when the user selects an element in the row or modifies the selected element.

(*) 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:

On the "Window" pane, in the "Order" group, click "Initialization".
In the window displayed, use the arrows on the right to modify the order in which the controls are initialized.

WEBDEV manages the following events by default (order of appearance in the code editor):

Event	Runtime condition

Initialization (Server code)	Run when the page is opened. Special case: Browsing List Box control filled automatically: When this code is run, the List Box control is not filled yet. To force the List Box control to be filled in this code, use: ListDisplay. the properties for managing browsing List Box controls: BrowsedFile, BrowsedItem or Filter.
End of initialization (Server code)	Code only for browsing List Box controls filled automatically: Run once the List Box control has been filled. This code allows you to select, add or modify an element in the List Box control.
Entry in control (Browser code)	Run when the control takes focus.
Exit without modification (Browser code)	Run when the Web user selects an element.
Whenever modified (Server code)	Run when the Web user selects an element.
Exit from control (Browser code)	Run when moving from one control to another (TAB key, selecting another control with the mouse, etc.)

Remark: Only the browser codes are available in a static page.

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,
left mouse button down, up, with a double click,
the right mouse button down, up, with double click,
the mouse wheel, etc.
