How can I remove all event listeners on all components at once, especially when it is not known what listeners are attached to each component? You can override mx.core.FlexSprite, which UIComponent inherets from, and generate an array of listeners created. Doug Mc Cune put up source code here . His blog says: removeAllEventListeners() – removes all event listeners of all types. This completely wipes out all event listeners for the component all at once. Let us know if this does the job! No! You might be able to mock something up with hasEventListener and willTrigger . But, there doesn't appear

Knowledge has no limits but still in your opions, what are the basic requirements for an individual, where he can call himself a flex developer. To make it a bit concrete lets say after having a 2-3 years experience. In my perspective it should be something like below. It is a very (very) rough idea and please let me know your views and suggestions on this. BASIC: (1) Knowldge about basic GUI components like tab, vbox, etc. Their properties and the ability to decide which component suits better in a condition. (2) Knowledge to use services like HTTP, wsdl, remote objects, etc. (3) knowledge

I'm new to flex , so forgive me if this is a dumb question. Right now I'm using custom events to pass data from one component to another. My problem is that events only bubble up. How can I pass data to a component that isn't a parent of the component dispatching the event? Here's the basic layout. I'm trying to get data from component 1 passed to component 3. Application MXML Component 1 Component 2 Component 3 If a piece of data is required by all components in a graph/tree, your best bet is to expose a public bindable property on each. Let the child components dispatch a bubbling event that

I have been trying to understand the way ActionScript's events are implemented, but I'm stuck. I know that AS is single threaded, which means that only one event handler will be executing at a time, and also means that handlers will be executed in a deterministic order*. For example, consider the following code: 1: var x = {executed: false}; 2: foo.addEventListener("execute", function(){ x.executed = true; }); 3: foo.dispatchEvent(new Event("execute")); 4: assert(x.executed); If ActionScript was multi-threaded, it would be possible that the assertion on line 4 could fail sometimes and succeed

I need to show few words in bold for radio buttons in Flex 3. something like the following: option 1: Hello world. option 2: Hello world. I see that there is no htmlText property for label of Radio Button. Anyone has any suggestions in accomplishing this requirement? Thanks Anji @Timofei Davydik You can include HTML Text inside RadioButton labels by extending RadioButton and overriding the updateDisplayList function. You need to change htmlText propert of textField to label's value inside this function. Here is the HTMLRadioButton Component package components { import mx.controls.RadioButton;

I'm trying to add a filter in AS3/Flex SDK. I can add a filter just fine to any one single object - but I want to apply the filter to everything that is a child of a certain object. Think a pause window pops up, and everything below the pause window goes blurry. Applying a filter to each individual object (eg: iterating through a list) doesn't work, as the filters from each object can then overlap and look pretty ugly. Does anyone know how to go about doing this? Is there a way to apply a filter to everything ? Here's a simplified version of the code: myCanvas.graphics.beginFill(0x00FF00,0.5);

I am working on a feature for an application that requires Flex 4 functionality. Due to some migration issues of the application from Flex 3.5 to 4.0, I have decided to implement this feature as a module that is compiled with Flex 4.0. The theory is that the application would remain compiled in Flex 3.5 and load the module when it needs it. Here is the module loading code: public function loadDiagModule():void { var moduleLoader:ModuleLoader = new ModuleLoader(); moduleLoader.url = "module/DiagrammerModule.swf"; moduleLoader.loadModule(); moduleLoader.addEventListener(ModuleEvent.READY,
