The zero-based index of the column that contains the item renderer where the event occurred.

The item renderer where the event occurred. You can access the data provider item using this property.

The reason the itemEditEnd event was dispatched. Valid only for events with type ITEM_EDIT_END. The possible values are defined in the ListEventReason class.

In the zero-based index of the row that contains the item renderer where the event occured, or for editing events, the index of the item in the data provider that is being edited.

Constructor. Normally called by the Flex control and not used in application code.

The ListEvent.CHANGE constant defines the value of the type property of the ListEvent object for a change event, which indicates that selection changed as a result of user interaction.

The properties of the event object have the following values:

The ListEvent.ITEM_CLICK constant defines the value of the type property of the ListEvent object for an itemClick event, which indicates that the user clicked the mouse over a visual item in the control.

The properties of the event object have the following values:

The ListEvent.ITEM_DOUBLE_CLICK constant defines the value of the type property of the ListEvent object for an itemDoubleClick event, which indicates that the user double clicked the mouse over a visual item in the control.

To receive itemDoubleClick events, you must set the component's doubleClickEnabled property to true.

The properties of the event object have the following values:

The ListEvent.ITEM_EDIT_BEGIN constant defines the value of the type property of the event object for a itemEditBegin event, which indicates that an item is ready to be edited.

The default listener for this event performs the following actions:

• Creates an item editor object via a call to the createItemEditor() method.
• Copies the data property from the item to the editor. By default, the item editor object is an instance of the TextInput control. You use the itemEditor property of the list control to specify a custom item editor class.
• Set the itemEditorInstance property of the list control to reference the item editor instance.

You can write an event listener for this event to modify the data passed to the item editor. For example, you might modify the data, its format, or other information used by the item editor.

You can also create an event listener to specify the item editor used to edit the item. For example, you might have two different item editors. Within the event listener you can examine the data to be edited or other information, and open the appropriate item editor by doing the following:

1. Call preventDefault() to stop Flex from calling the createItemEditor() method as part of the default event listener.
2. Set the itemEditor property to the appropriate editor.
3. Call the createItemEditor() method.

The properties of the event object have the following values:

The ListEvent.ITEM_EDIT_BEGINNING constant defines the value of the type property of the ListEvent object for a itemEditBeginning event, which indicates that the user has prepared to edit an item, for example, by releasing the mouse button over the item.

The default listener for this event sets the List.editedItemPosition property to the item that has focus, which starts the item editing session.

You typically write your own event listener for this event to disallow editing of a specific item or items. Calling the preventDefault() method from within your own event listener for this event prevents the default listener from executing.

The properties of the event object have the following values:

The ListEvent.ITEM_EDIT_END constant defines the value of the type property of the ListEvent object for a itemEditEnd event, which indicates that an edit session is ending.

The list components have a default handler for this event that copies the data from the item editor to the data provider of the list control. The default event listener performs the following actions:

• Uses the editorDataField property of the list control to determine the property of the item editor containing the new data and updates the data provider item with that new data. Since the default item editor is the TextInput control, the default value of the editorDataField property is "text", to specify that the text property of the TextInput contains the new item data.
• Calls the destroyItemEditor() method to close the item editor.

You typically write an event listener for this event to perform the following actions:

• In your event listener, you can modify the data returned by the editor to the list component. For example, you can reformat the data before returning it to the list control. By default, an item editor can only return a single value. You must write an event listener for the itemEditEnd event if you want to return multiple values.
• In your event listener, you can examine the data entered into the item editor. If the data is incorrect, you can call the preventDefault() method to stop Flex from passing the new data back to the list control and from closing the editor.

The properties of the event object have the following values:

The ListEvent.ITEM_FOCUS_IN constant defines the value of the type property of the ListEvent object for an itemFocusIn event, which indicates that an item has received the focus.

The properties of the event object have the following values:

The ListEvent.ITEM_FOCUS_OUT constant defines the value of the type property of the ListEvent object for an itemFocusOut event, which indicates that an item has lost the focus.

The properties of the event object have the following values:

The ListEvent.ITEM_ROLL_OUT constant defines the value of the type property of the ListEvent object for an itemRollOut event, which indicates that the user rolled the mouse pointer out of a visual item in the control.

The properties of the event object have the following values:

The ListEvent.ITEM_ROLL_OVER constant defines the value of the type property of the ListEvent object for an itemRollOver event, which indicates that the user rolled the mouse pointer over a visual item in the control.

The properties of the event object have the following values:
