Here’s a quick way of restarting your Flex Application without reinitializing everything through a function

navigateToURL(new URLRequest(Application.application.url), ‘_self’);

In order to change the mouse cursor to a hand cursor when a mouse over a particular component in Flex Component you will need to set useHandCursor = true , however if you set this to true you will not be able to get the hand cursor unless you set another two properties on the Flex component , buttonMode = true and mouseChildren = false.

Here’s an example

1
2
3
4

var label:Label = new Label();
label.buttonMode = true;
label.useHandCursor = true;
label.mouseChildren = false;

Once you set all three property of the component you will have the hand cursor when the mouse moves over the flex component.

Recently I was working on a project that I was using MouseEvent.DOUBLE_CLICK and the darn thing wasn’t firing no matter how many times that I’ve clicked on it. After awhile I remember that most  Flex component actually have a doubleClickEnable property . Guess what was the result of the trace when I did

1

trace(image.doubleClickEnabled) // this will return false

The simple solution for getting MouseEvent.DOUBLE_CLICK to work is to ensure that you set the property of doubleClickEnable to true

image.doubleClickEnabled = true;
image.addEventListener(MouseEvent.DOUBLE_CLICK, double_click);

While working on a new project using Flex and Webservices, I got this annoying message when I’m trying to use dataprovider and custom ItemRenderer

warning: unable to bind to property ‘xxx’ on class ‘xxx’ (class is not an IEventDispatcher)
warning: unable to bind to property ‘xxx’ on class ‘xxx’ (class is not an IEventDispatcher)
This is happening because binding fails when using complex objects  , the compiler doesn’t know what kind of datatype that is being looped in the Repeater class and spits out a warning. Depending on what you are trying to do , sometimes it wont even spit out the data. The quick solution is to extend your class to Object and to make it bindable.

Here’s an example

package com.thedesilva
{
import mx.rpc.soap.types.*;
/**
* Wrapper class for a operation required type
*/
[Bindable]
public class Magazine extends Object
{
/**
* Constructor, initializes the type class
*/
public function Magazine() {}
 
public var id:String;
public var imagename:String;
public var name:String;
}
}
