Adobe AIR : Flex 에서 FileSystemDataGrid control로 확장자 기준으로 파일 필터 하는 방법

The following example shows how you can filter files based on file extensions in the Adobe AIR FileSystemDataGrid control by setting the extensions property.Full code after the jump.

<?xml version="1.0" encoding="utf-8"?>

<mx:WindowedApplication name="FileSystemDataGrid_extensions_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">
 
    <mx:Script>
        <![CDATA[
            private function init():void {
                arr = [dataGrid.nameColumn,
                        dataGrid.typeColumn,
                        dataGrid.sizeColumn];
            }
        ]]>
    </mx:Script>
 
    <mx:Array id="arr" />
 
    <mx:FileSystemDataGrid id="dataGrid"
         extensions="[mxml,xml,swf]"
         columns="{arr}"
         horizontalScrollPolicy="off"
         width="100%"
         height="100%"
         initialize="init();" />
 
</mx:WindowedApplication>

You can also set the extensions property in MXML using the <mx:extensions> tag, as seen in the following example:

<?xml version="1.0" encoding="utf-8"?>

<mx:WindowedApplication name="FileSystemDataGrid_extensions_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">
 
    <mx:Script>
        <![CDATA[
            private function init():void {
                arr = [dataGrid.nameColumn,
                        dataGrid.typeColumn,
                        dataGrid.sizeColumn];
            }
        ]]>
    </mx:Script>
 
    <mx:Array id="arr" />
 
    <mx:FileSystemDataGrid id="dataGrid"
         columns="{arr}"
         horizontalScrollPolicy="off"
         width="100%"
         height="100%"
         initialize="init();">
        <mx:extensions>
            <mx:String>mxml</mx:String>
            <mx:String>xml</mx:String>
            <mx:String>swf</mx:String>
        </mx:extensions>
    </mx:FileSystemDataGrid>
 
</mx:WindowedApplication>

You can also set the extensions property using ActionScript, as seen in the following example:

<?xml version="1.0" encoding="utf-8"?>

<mx:WindowedApplication name="FileSystemDataGrid_extensions_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">
 
    <mx:Script>
        <![CDATA[
            private function init():void {
                dataGrid.extensions = ['mxml', 'xml', 'swf'];
 
                arr = [dataGrid.nameColumn,
                        dataGrid.typeColumn,
                        dataGrid.sizeColumn];
            }
        ]]>
    </mx:Script>
 
    <mx:Array id="arr" />
 
    <mx:FileSystemDataGrid id="dataGrid"
         columns="{arr}"
         horizontalScrollPolicy="off"
         width="100%"
         height="100%"
         initialize="init();" />
 
</mx:WindowedApplication>
