AgeFileFilter

To get the list of files of directory is simple. If we want the list of files depending on the modified date time of the file. This can be achived by using AgeFileFilter from Apache’s commons-io.

Get the list of files which is modified with in 24 hrs:

String files[] = new File("myLocation").list();

will return all files in the folder(myLocation).
To get the recent files we can use AgeFileFilter

private static FileFilter getFileFilter() {
	Calendar cal = Calendar.getInstance();
	cal.add(Calendar.DATE, -1);
	return new AgeFileFilter(cal.getTime(), false);
}

Here AgeFileFilter takes cutoff period and a boolean
boolean false indicates the files created after the given cutoff period and vice versa.
And this FileFilter has to apply for the listFiles of dir

Files files[] = new File("myLocation").listFiles(getFileFilter());

will return the array of files which are been modified with in 24 hrs.

Get attribute names and values of xml in flex

One more sample to parse xml file with attributes in flex. Here is a sample, which displays the capital city and language of the selected country in the combobox. The details were getting through xml file with three attributes “country”, ”capital” and “language”.

In the creationComplete event of application an HttpService is sent and got country.xml as its response. To get the attributes details attributes() method of XML is used and it will return XMLList (this can also be achieved  by xml.@* and it will also return XMLList). To get the attribute name use name() method of XMLList and we can directly get the value of attribute from the list by index number.

We can modify the attributes names, count and values without change in the flex code, just by changing in the xml file. In this xml I just included country name, capital city and language and you can include values like currency, continent etc.,

ComboBox ItemRenderer in flex DataGrid

For my Application I need a CobmboBox in Datagrid, and the combo will have a list of data. For this I googled a few samples. Here is a sample code, I modified it with my requirements.

My requirement is populate the Datagrid and there will be columns in datagrid that can be modified and updated to the database. To achive this I created ComboBox as ItemRenderer in the DataGridColumn. The data to the Combo must be dynamic.

Sample Code

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
 creationComplete="fillDataGrid()">

 <mx:Script>
 <![CDATA[
 import mx.collections.ArrayCollection;

 //  data provider of combo in datagrid, can get dynamic data by a service
 private var comboData:Array = new Array("Value0","Value1","Value2","Value3");

 /**
  *  populate the datagrid with sample data
  */
 private function fillDataGrid():void {
 var arrColl:ArrayCollection = new ArrayCollection;
 for (var i:int=0,j:int=0; i<50; i++,j++ ) {
 if ( j>3 ) j=0;

// create an object that will be provided to combo
 var obj:Object = new Object;
 obj.value = "Value"+j;
 obj.list = comboData;

// data is for first column, com is for the itemrenderer in that com object
 //value is slectedItem of combo and list is the provider of that combo
 arrColl.addItem({data:"data"+i, com:obj});

}

dg.dataProvider = arrColl;

}
 ]]>

</mx:Script>
 <mx:DataGrid id="dg" x="60" y="21" rowCount="5">
 <mx:columns>
 <mx:DataGridColumn dataField="data" headerText="Data" />
 <mx:DataGridColumn headerText="Value" itemRenderer="DynRender" />
 </mx:columns>
 </mx:DataGrid>
 </mx:Application>

DynRender.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" horizontalScrollPolicy="off">

<mx:Script>
<![CDATA[

 override public function set data(value:Object):void {
   if(value != null) {
    super.data = value;
    mycombo.selectedItem=data.com.value;
   }

 }
 ]]>

</mx:Script>
<mx:ComboBox id="mycombo" dataProvider="{data.com.list}" width="100%"  />
</mx:Canvas>

The required data for the combo box is provided by the collection in ‘com’ item, In that we will provide the list item as dataprovider of the combo box. And value will the the selectedItem.

Embedding font in Flex 4 (spark components)

Embedding fonts in Flex 3 can be achived by

@font-face {
 src : url("comic.TTF");
 fontFamily : comic;
 }

But this will not work in flex 4. We need to add one more property ‘cff’ and setting it to true.

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/halo"

 <fx:Style>
 @namespace mx "library://ns.adobe.com/flex/halo";
 @namespace s "library://ns.adobe.com/flex/spark";

 @font-face {
 src : url("comic.TTF");
 fontFamily : comic;
 cff : true;
 }
 .myStyle {
 font-family : comic;
 font-size : 24;
 }
 </fx:Style>

 <s:RichText fontFamily="comic" x="40" y="23">
 Embedding font in flex 4 - RichText
 </s:RichText>
 <s:SimpleText styleName="myStyle" x="40" y="63">

Flex with Struts 2 with Source

In my previous post (http://niamathbasha.wordpress.com/2008/09/01/configuring-struts-2-with-flex/) I discussed about configuring flex with Struts 2. So many guys asking me to provide the working sample. So I configured a small Login application.

Download the sample application which uses Flex as UI and Struts 2  as Back-end.cairngorm-template.rar

Exporting DataGrid to CSV using Flex with Java

Exporting of DataGrid data to CSV format in Flex and Action Script 3.0

Converting Data Grid data to String (csv format):

private function exportToCSV():String {
 var xmlListColl:XMLListCollection = new XMLListCollection;
 xmlListColl= myDataGrid.dataProvider as XMLListCollection;

var csvData:String = '';
 // To get Headers
 var attrList:XMLList = xmlListColl[0].@*;
 for (var i:int = 0; i < attrList.length(); i++) {
 csvData += attrList[i].name() + ',';
 }

 csvData += '\n';
 //    To get actual data
 for ( var j:int = 0; j &amp;amp;lt; xmlListColl.length; j++) {
 var record:XMLList = xmlListColl[j].@*;
 for ( var k:int = 0; k < record.length(); k++) {
 csvData += record[k] + ',';
 }
 csvData += '\n';
 }
 return csvData;
 }

The above function will convert DataGrid data(if its data is in xml format) to csv format.

If you want to create a csv file then you have to send to the server and then download the csv file.

For sending this data to server side (implemented in java) you can use simple HTTPService in flex

and sending with the paramater – csvData what we created in above function.

In Java we will use a simple servlet.

byte[] output = request.getParameter( "input" ).getBytes();

 response.setContentType("text/csv");

 response.setHeader("Content-Disposition", "attachment; name=\"Result\"; filename=\"Result.csv\"");

 response.setContentLength( output.length );

 response.getOutputStream().write( output );

Just copy the above code in servlet that will return an output stream. Take this responce to flex

use ExternalInterface call to accept that stream and it will show you dialog box with Open and Save option

in this way we can export the datagrid data to a csv file.

Customizing scrollbars in flex using css

This css will remove the Up arrow and Down arrows from the ScrollBar.

And the thumb and track of ScrollBar is customized with images(15X15).

By changing the thumb image and track image we change the Scrollars theme

This will create a component in which images will be displayed in horizontally aligned box.

By fixing the size of HBox, images will be displayed with in that area. By clicking on left

animation effect. We can change the effects as per the requirement
