282 DataGrid component (Flash Professional only)
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.columnStretch
event’s event object has two additional properties:
columnIndex A number that indicates the index of the target column. The first position
is 0.
type The string "columnStretch".
For more information, see “EventDispatcher class” on page 499.
Example
The following example displays the column index number in the Output panel when the title
is resized. With a DataGrid instance named
my_dg on the Stage, paste the following code in
the first frame of the main timeline:
my_dg.setSize(240, 100);
// Set up sample data.
var myDP_array:Array = new Array();
myDP_array.push({id:0, name:"Clark", score:3135});
myDP_array.push({id:1, name:"Bruce", score:403});
myDP_array.push({id:2, name:"Peter", score:25});
my_dg.dataProvider = myDP_array;
// Create listener object.
var dgListener:Object = new Object();
dgListener.columnStretch = function(evt_obj:Object) {
trace("column " + evt_obj.columnIndex + " was resized");
};
// Add listener.
my_dg.addEventListener("columnStretch", dgListener);
