Flex :: Emphasize A Specific UI Component
Mar 27, 2011
I'd like to add visual emphasis to a selected UI component by de-emphasizing everything around it, e.g. make everything around it blurry, or more transparent, or something similar. Two questions, really: spec: what effect would you use do build something like this? Do you know of any software that does this well? implementation: what is the most obvious approach to apply a blur, or change alpha, to everything around a specific component?

I have an application in flex, it has some components out of the box and quite a few of custom components and events. I want to get all event listeners on a specific component in runtime, I know how to do it with monkey-patching the framework but I do not want to use a monkey patch nor can I rely on this in production.

I'm trying to determine with the help of a mouse event if I'm over a specific component. So right now I have two components, let's say buttonA and buttonB. ButtonA has a listener on it already listening for the mouse out event. ButtonB is flush against the edge of ButtonA. I need to find out the code for it. Here is more details:

I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?

I have multiple "Loader Components" placed in a grid that are working great for loading external JPEG's. However, when I publish my file the "Loader Components" load each image randomly (I assume because they load the smallest file in size first then next largest and so on). How do I load the content of multiple "Loader Components" in a specific sequence?
Here is the script I have so far:
////"Thumb1" is the instance name of the first "Loader Component" in the grid.
Next is "Thumb2", then "Thumb3" and so on
Thumb1.load()
if (Thumb1.percentLoaded >= 1 ) {
Thumb2.load();}
if (Thumb2.percentLoaded >= 1) {
Thumb3.load();}
if (Thumb3.percentLoaded >= 1) {
Thumb4.load();}
if (Thumb4.percentLoaded >= 1) {
Thumb5.load();}

There is a number of Flash and AJAX based uploaders around. I need a file upload component for an existing form in an existinc application, so I have very specific requirements for it. Maybe somebody knows one off the top of their head and saves me a lot of research.
I need a file upload component that has a progress bar and "upload" button next to it (= standalone functionality, no connection to the submit event of a surrounding form).
It should be either Flash or Prototype based. No JQuery or Moo, as the app runs with prototype.
If server-side scripting is needed, it must be PHP. No Perl, no ASP.
On successful upload, I need a custom Javascript function triggered. (I need to update a file list that is displayed on the same page.)
The possibility of filtering file names before upload (no Umlauts, spaces..) would be a plus.
I will try to give this question a bounty in a minute if I'm allowed to.
Edit: I can't seem to open a bounty. Do I have to wait first?

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?

I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

I have a component with a public variable declared
[Bindable]
public var mnuSource:String;
When I extend this component, I can reference mnuSource (it compiles) but Runtime complains about the property not being accessible (error 1056).
How do you modify / declare component properties so they are actually available to other components?

I'd like to use a button within a component to remove it. So, you click it and the component is gone. But, I haven't figured out how you reference the component from within the component. What should I put in click=""?
My component: popCanvas
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Panel width="200" height="200" title="hello"
click="remove=">

Below is the overriden on complete function for a preloader in Flex.
private function initComplete(e:Event):void
{
//dispatchEvent(new Event(Event.COMPLETE));
cp.status.text="Configuring... Please Wait";
}
What I want to do is when the app has finsihed loading I want to change the preloaders text to "configuring".Then I want to go and do a bunch of setup stuff in my code.Once I've done all the setup I wanted how can I get the Preloader to dispatch its Event.complete from else where in my code?I tried Application.application.preloader but it comes up null.So I guess my question really is how to access a preloader from anywhere in my application. Would a better approach be to have all setup classes as members of my preloader class?

I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?

What I want is a hint how to make a specific thing happen while clicking a specific button. Like "if I click button 1, do this". Would like to use this script though I'm gonna add buttons over time and this is an easy way to have the functionality working.
Here's the code:
Attach Code
function hitButton(btn) {
btn.onRollOver = function() {
this.colorTo (0xC4006A);

But that really just gives me back the original XML (since I'm asking for the root where those conditions are met I get the root). I understand why my approach doesn't work, but I don't know where to go from here./grandParent

I have a dataGrid component in flex. My grid has few rows. I simply want to make the last row bold. I just can't figure how to do it.
I thought about an idea : create a factory that gets parameters so that i can pass the itemRenderer the total count of rows. But, i don't know how to check the current row in the itemRenderer itself (and compare it to the total rows).

I want to extend the RadioButton component in Flex 3, adding a text input line to it in place of the label. Is it possible to do this?Alternately, is it possible to have a container -- such as an HBox -- delegate all properties to an internal component -- such as a RadioButton -- so that I could create a composite component that 'acts like' a radio button?

I have a component called a TableDataViewer that contains the following pieces of data and their associated set functions:[code]This component is nested in another component as follows:[code]Looking at the trace in the logs, the call to set table is coming before the call to set dataSetLoader. Which is a real shame because set table() needs dataSetLoader to already be set in order to call its load() function.So my question is, is there a way to enforce an order on the calls to the set functions when declaring a component?
