Re: [flexcoders] Stopping double-click of a button 'bubble' to the datagrid row

[Beau Scott]

Event.stopPropagation() or stopImmediatePropagation() (depending on whether
you want events on the current node to be executed before the event stops or
not:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="horizontal" xmlns:local="*">
    <mx:Script>
        <![CDATA[
            [Bindable]
            public var dp:Array = [
                {foo: "button 1"},
                {foo: "button 2"},
                {foo: "button 3"},
                {foo: "button 4"},
                {foo: "button 5"},
                {foo: "button 6"},
            ];

            private function dg_doubleClickHandler(event:Event):void
            {
                trace('dg double click');
            }
        ]]>
    </mx:Script>

    <mx:AdvancedDataGrid id="dg" doubleClickEnabled="true"
doubleClick="dg_doubleClickHandler(event)" dataProvider="{dp}">
        <mx:columns>
            <mx:AdvancedDataGridColumn dataField="foo" >
                <mx:itemRenderer>
                    <mx:Component>
                        <mx:Button doubleClickEnabled="true"
label="{listData.label}"
                            doubleClick="trace(listData.label + ' double
click'); event.stopImmediatePropagation();" />
                    </mx:Component>
