DataGrid.cellFocusOut
Availability
Flash Player 6 (6.0 79.0).
Edition
Flash MX Professional 2004.
Usage
listenerObject = new Object();
listenerObject.cellFocusOut = function(eventObject){
// insert your code here
}
myDataGridInstance.addEventListener("cellFocusOut", listenerObject)
Description
Event; broadcast to all registered listeners whenever a user moves off a cell that has focus. You can
use the event object properties to isolate the cell that was left. This event is broadcast after the
cellEdit event and before any subsequent cellFocusIn events are broadcast by the next cell.
Version 2 components use a dispatcher/listener event model. When a DataGrid component
dispatches a
cellFocusOut event, the event is handled by a function (also called a handler) that is
attached to a listener object that you create. You call the
addEventListener() method and pass
it the name of the handler as a parameter.
When the event is triggered, it automatically passes an event object (
eventObject) to the
handler. Each event object has properties that contain information about the event. You can use
these properties to write code that handles the event. The
DataGrid.cellFocusOut events event
object has three additional properties:
columnIndex A number that indicates the index of the target column. The first position is 0.
itemIndex A number that indicates the index of the target row. The first position is 0.
type The string "cellFocusOut".
For more information, see “EventDispatcher class” on page 415.
Example
In the following example, a handler called myListener is defined and passed to
grid.addEventListener() as the second parameter. The event object is captured by the
cellFocusOut handler in the eventObject parameter. When the cellFocusOut event is
broadcast, a
trace statement is sent to the Output panel.
var myListener = new Object();
myListener.cellFocusOut = function(event) {
var cell = "(" + event.columnIndex + ", " + event.itemIndex + ")";
