Provide a Better Visual Feedback – Using Flex CursorManager.setBusyCursor()
Posted on February 25, 2010 by Sameera Thilakasiri
Why do you need Flex CursorManager
Flex is all about User Experience. A Rich Internet Application (RIA) is not just attractive skins or fancy animations. It also means interacting with users and helping them use your application better.
One important part of User Experience is to provide a better visual feedback. For example, when someone types a model name and clicks Search button, it might take 2-3 seconds to get results from a web service. What would a user do during that time? He or she probably keeps clicking the Search button, or thinks your application is dead.
So how to let users know what is going on with your application? You need how do i buy viagra online | buy cialis canadian | cheap levitra generic to give them some visual feedback: like show the busy cursor when waiting for the back end response, and then remove the busy cursor when the data is ready.

Here is how you typically use CursorManager in Flex:
– Display the default busy cursor
CursorManager.setBusyCursor();
– Remove the busy cursor
CursorManager.removeBusyCursor();

private var HeartCursor:Class;
var cursorID:int = CursorManager.setCursor(HeartCursor);

– Remove all cursors
CursorManager.removeAllCursors();

Changing the Flex ComboBox control’s opening and closing easing functions and ColorPicker control’s easing duration
Posted on February 22, 2010 by Sameera Thilakasiri
Changing the Flex ComboBox control’s opening and closing easing functions and Changing the ColorPicker control’s easing duration and easing functions
This entry looks at customizing the ComboBox control’s openDuration and closeDuration styles which control how long it takes for the dropdown menu to appear or disappear. By default both of these styles are set to 250 milliseconds (1/4 second). We’ll also look at changing the easing method used to animate the dropdown menu. Finally, we look at explicitly setting the dropdown menu’s width so it doesn’t inherit the ComboBox’s width and alternate the row colors for the items in the dropdown.

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

prompt="Please select an item..."
<a href="http://amoxil-cheap.net">cheap amoxil</a> selectedIndex="-1"

</mx:Array>
</mx:dataProvider>
</mx:ComboBox>
</mx:Application>
The following example shows how you can control the easing duration and easing functions that the ColorPicker control uses to display its drop-down swatch palette. Of course, this probably isn’t the best example of “useful animation” and will probably just annoy users (the long 2 second easing animation), but it is nice to know that you can change these if you need to.

Embedding fonts in AS3
Posted on February 22, 2010 by Sameera Thilakasiri
No more do you have to have fonts in your library you can embed them directly from the folder where they reside using the [Embed] in your ActionScript Project.
You supply the path to the font in the ’source’ param and then store a name to be referenced to access the font in ‘fontFamily’. You also need to declare a variable of type String or Class for the [Embed] to be assigned to, although you don’t need to reference it in your code.
To access the embeded font you use the String you assigned to the var ‘fontFamily’
package
{
import flash.display.Sprite;
import flash.display.TextField;
import <a href="http://all-forums.biz/images/index.php">cheap levitra generic</a> flash.display.TextFieldAutoSize;
import flash.text.TextFormat;
import flash.text.AntiAliasType;
public class EmbedFontTest extends Sprite
{
[Embed(source="C:\WINDOWS\Fonts\ARIAL.TTF", <a href="http://jtc-enterprises.com/images/">buy viagra online order</a> fontFamily="Arial")]

private var _text_txt:TextField;
public function EmbedFontTest()
{
super();
this.initEmbedFontTest();
}
private function initEmbedFontTest():Void
{
this._arial_fmt = new TextFormat();
this._arial_fmt.font = “Arial”;
this._arial_fmt.size = 40;
this._text_txt = new TextField();
this._text_txt.embedFonts = true;
