Events associated with Combo Box controls

Default events

Events supported by WINDEV and WINDEV Mobile

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

Event	Runtime condition

Initializing	Executed when the window is opened. () Special case: file combo automatically filled*: 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, or Combo Box control file properties: BrowsedFile, BrowsedItem or Filter.
End of initialization	Code present only in automatically populated Combo Box controls based on a data file: Executed once the Combo Box control has been populated. This code allows you to select, add or modify an element in the control.
Entry	Executed when the control gains focus
Exit	Executed when a field is changed (TAB key, changing a field with the mouse, etc.).
With each modification	Code present only in editable Combo Box controls: Executed when the user enters data in an editable Combo Box control.
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.

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.
Note: Several optional events can be selected.
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.
