Events associated with List Box controls

Default events

The following events appear by default in the WINDEV and WINDEV Mobile code editor:

Event	Runtime condition

Initialization	Executed when the window is opened. () Special case: List Box control automatically fills in a file:* When this code is executed, the List Box control is not populated yet. To populate this control in this code, use: the ListDisplay function. or List Box control properties: BrowsedFile, BrowsedItem or Filter.
End of initialization	Code only for automatically populated List Box controls based on a data file: Executed once the List Box control has been populated. This code allows you to select, add or modify an element in the control.

Exit	Executed when moving from one control to another (TAB key, selecting another control with the mouse, etc.).
Selecting a row	Executed when the user selects an element in the row or modifies the selected element.

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

On the "Window" tab, in the "Order" group, click "Initialization".
In the window that appears, use the arrows on the right to change the order in which the controls are initialized.

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

Event	Runtime condition

To populate this control in this code, use: the ListDisplay function. List Box control properties: BrowsedFile, BrowsedItem or Filter.

Several optional events can be added.

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.
