Actionscript :: Validate On Demand A Flex 4 Component Size?
Nov 16, 2010
I have a component and I add some content to it making it change it's size, immediately I need it's new size, but flex only updates the size in the next frame by calling updateDisplayList. how can I force it to update the size of the component right away.

I want to create a panel (or any other component) inside a component that has a 5 pixel border on all sides, but scales fully when the window is resized. I know I can set width to "100%" to make it resize, but that gives me no borders. If I put it to "95%",I have borders, but they scale annoyingly. Also, that only works for borders on the right or lower bounds, and not to the left or upper sides.Is there a convenient way to do this without having to write tons of resize-code (in which case I will not bother and just accept bad rescale behaviour, as it is for a private pet project).
EDIT: I know that I can just overwrite the display handling and set the positions manually every frame. I wondered if there is a cheap way to do it in the mxml-structure, along these lines:
<mx:Panel>
width="100%" height="100%"
</mx:Panel>
Coming from C++ and Java, I am intrigued by the option of setting something to "95%" and let the library work out the details, instead of having to write many lines of code, just so my text-area always keeps a 5 pixel distance from the border, but scales with window width.If there is no easier way to do it than figuring out pixel sizes by hand and setting the coordinates.

In order to play a FMS stream (live or on demand), either an FLVPlayback component or the Video class is needed.And they require ActionScript 3 and Flash 8 or above.
As far as i know , Youtube, Dailymotion and Google Video stream their on demand videos from a FMS, and their players are compatible with Flash 7.
How can they achieve this? If Youtube, Google and Dailymotion do that, i deduce it's possible..
I tried to create a Flash 7 application that plays a video coming from FMS, using a MediaDisplay component, but it doesn't work well. Sometimes it shows the video, sometimes not.So i don't think youtube player uses MediaDisplay..

I'd like to get the actual height of a component after adding some children.
When inspecting the variables tab in debug mode, I see 2 different height variables:$height (which contains the correct value: 138) and height/_height (which contains a wrong value: 10).
I guess that the display is not updated and so I'm not getting the correct height using component.height, but how can I get the value in $height?

I'm building a flex .swc library using Ant, and many of the assets that are supposed to be in the file are not being copied, instead creating 0-byte entries in the .swc.Here is the ant compc target that is doing the creation. I've tried both compiler.include-libraries and compiler.library-path here, which is why the latter is still present and commented out. Neither worked.

Is there a good place that has an overview of how Flex layout stuff is managed? I'm trying to create some user-resizeable "windows" in Flex, but I'm having some trouble getting the layout calculations for the contents correct. Right now I'm just trying to get a good understanding of how Flex calculates its layouts, but I haven't found any good overview documentation. For instance, looking just at the width value there are the following:
[Code]....
and the same set for height. What's the meaning of each of these? How is each used? Is there any way using those to calculate some preferred size of a component (like getPreferredSize() in java)?

Im trying to create a layout in flex using mxml, the layout contains a Canvas component and a Box.

My MXML is as follows;

i'm trying to create a unordered list in Flex. My issue is that within each line, i want the word NEW to be a different font color and different font size from the rest of the label text. I am unsure of how to do this INLINE within the label component.
<s:VGroup fontSize="15" color="#ffffff">
<s:Label text="u2022 NEW Invite your friends!" />
<s:Label text="u2022 NEW Features coming soon!" />
<s:Label text="u2022 NEW Invite your friends!" />
</s:VGroup>

I have a component called X. I'm trying to make a menu come down from it when I put my mouse over it.
I have a mouseOver handler which changes the component's state to another state which shows an extra child component (the menu) on the lower part. This of course makes the X component grow.
I also have mouseOut event handler which makes the menu disappear by returning component X to its original state.
When I move the mouse over the component the menu appears as expected. But when I move the mouse down to the menu that is now visible, as soon as I touch it, it disappears. This way it's impossible to reach the menu.
I guess the mouseOut event is triggered as soon as I move out of the old boundaries. Is this so? And how can I avoid it? The new boundaries should now consider the extra child with the menu.

I can change the color of the label in Flex Builder, I can even BIND the color to a variable and that works, but I can't find the Color PROPERTY in order to change or reference it programatically! What is the ActionScript 3.0 code to change the font or color of a piece of text in a Flex RIA - or is caring in what color your text appears too bizzarre a request for a RIA? I wrote whole applications after just minutes of "learning" flex, how come it's taken me three days and I still can't change the color of my stupid label?

I'm trying to come up with the optimal solution for validating IP addresses in Adobe Flex. My current solution is to use a regexp validator and look for dotted quad numbers, see code below. For some reason this will also allow an address like "1.2.3.4.5".
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
<fx:Script>

I'm trying to make an existing FLEX application section-508-compliant, by getting it to work smoothly with the JAWS screen reader. It kinda sorta works, but one immediate problem is that when you first go to the login screen, your cursor ends up in the userid field, but JAWS doesn't read anything useful (like the label of the field you're in!) until you hit TAB or something. Is there a way to force it to speak immediately on application startup, without making the user tab/backtab just to hear where they are?
For that matter, as cool as it is that it reads interactive controls as the user tabs around, sometimes you just need to make JAWS say something at a particular point in the logic, which might or might not be associated with a conrol... as if you could write AS code like "jaws.speak('');".

I have a Flex application that edits a moderately complex object, and I'd like to put some client-side validation in place on multiple parts of the editor.The editor is a set of nested objects:[code]The structure echoes the data model fairly closely, and the UI is what the project requires, so I'm not going to be too quick to restructure the classes there if I don't have to -- time is an issue too. What I want to do is have validators for each of the Component* instances that:[code]Show the validation tool tips and UI hints on the relevant UI element.Disable the SubmitButton when any part of the form is not valid(Optionally) provide enough information that I can display an error message in the form.

I have a DataGrid which uses an itemRenderer to display the items in a DataGridColumn. The ItemRenderer is created in actionscript and contains the following code:
public class PromptingColumnRenderer extends Label {
public function PromptingColumnRenderer()
{
[Code].....
In this DataGrid column, I require number validation on only the data with the type="NUMBER" field set. The problem is, when I try to declare a NumberValidator within my PromptingColumnRenderer actionscript code, the view recycles the renderer, and the NumberValidator attempts to validate non-numeric rows. What is the best way to validate only the rows with the type="NUMBER" field set?

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 three images and I want change the images size based on the scene size (default size is 1024x768). After each image has completely loaded I call bindableUtils.setter to set width/height when scene size changes but I don't know how to make a pointer or something like that. I'm using a public var img, but it only works with the last complete image.
