Flex :: Right Method For Modifying Text Content In Component Lifecycle?
Aug 25, 2010
I have custom components which must adjust their text content based on space constraints. For example a component adds labels until there is no space, and then the content of the last label becomes "(x more)"
I do not have access to size of child controls before adding them. When in updateDisplayList, I make changes to the layout of the component, but for labels, lblInstance.text property fires events, which lead to updateDisplayList being called again. I know that updateDisplayList may be called more than once, but if there is a way to modify text without triggering events, that'd be really useful. For example, setActualSize method in UIComponent allows this kind of modification. Anything similar for text controls? Or do you have best practices for laying out and managing text content, in the context of custom Flex components?

I am extending VBox to make a Calendar component. What method should I override to add the code to draw itself? What is the difference between all these methods? Is there something I should be putting in each one, or is there a specific method I can just override, add my drawing code, and have it work?

I need to find a way to "upsample" text from 72dpi (screen) to 300dpi (print) for rendered client generated text. This is a true WYSIWYG application and we're expecting a ton of traffic so client side rendering is a requirement. Our application has several fonts, font sizes, colors, alignments the user can modify in a textarea. The question is how to convert 72dpi to 300dpi. We have the editior complete, we just need to make 300dpi versions of the textarea.
1) Get textarea and increase the height, width, and font size by 300/72. (if ints are needed on font size I may need to increase the font then down-sample to the height/width)
2) use BitmapUtil.getSnapshot on the textarea to get a rendered version of the text.[code]

I've read in the flex developer guide that you sometimes need to override one of the lifecycle methods like: commitProperties and updateDisplayList but I've written a few flex apps without ever needing to implement them.when do I need to override them?

Create a tab navigator (or viewstack, whatever) and add a couple tabs. On your tab add a show event handler. Inside the event handler call invalidateProperties() and invalidateDisplayList() on one of the children of your tab. Put a break point on the childs commitProperties() and updateDisplayList(). You'll notice that the updateDisplayList() gets called before commitProperties() which results in incorrect behaviour.
I noticed this problem when setting a DataGrid's dataprovider from inside the show handler. Setting the dataProvider causes the grid to invalidate both properties and displayList, updateDisplayList() will get called first, then commitProperties() which will result in the grid not updating the rows. It appears the root of the problem is that the show event gets dispatched from within LayoutManagers validateDisplayList() loop, so invalidating a child object from within the show handler results in its updateDisplayList() getting called immediately.

<![CDATA[
public function loadDetails(id:String) : void { // Some code here

When I tried to run this code Flex throws an error. It says that loadDetails is not defined. I suppose that error is because of scope.

could anyone help me modify the code for these checkbox components? right now, the SUBMIT button checks which ones of the checkboxes are checked and gets their label, then writes the appropriate labels in a dynamic text box.[code]For the program I am doing, I need to have a maximum of 6 checkmarks and each one of the checked label must go into its own variable. (see gray part of the swf) I would also like the labels to appear in the right order, right now it's inversed.

I'm creating a flex-based video player, using the FLVPlayback component (imported from Flash Pro CS3). I've reskinned all of the player controls and linked them in, and it's all working really well...However, if you try to seek beyond the point where the video has loaded (it's using progressive download), the video completely freezes. You can no longer pause, play, seek to somewhere else, or anything. I understand it can't actually play a point in the video that hasn't been downloaded, but the whole thing seems to just become unresponsive

I'm trying to write a custom fadeTo(component, x, y):void method, which takes an arbitrary Flex Component as an argument and moves it to a given location, but smoothly.
The problem I'm running into is the following.
I want to send the component itself as argument, like this: (using Button as an example only)
fadeTo(myButton, 200, 500);
(this should move myButton smoothly from its current position to the position indicated as parameter)
However, I don't really know what type an arbitrary Flex Component is. How should I handle that?

I'm trying to build a schedule with Flash CS4 and Actionscript 3.0 for an Internet radio station. I'd like to have a .swf that I can open, drag and drop a text symbol from the Library (ideally, for design reasons), and then change the color of the text with Actionscript when the user presses a button.
I can change the color of text if I create it with Actionscript, of course, but I'm not sure how to use Actionscript to change the color of text I've created in the Flash GUI. I can't pass a TextField to a symbol and expect Flash to know what to do with it, can I?

I've been slowly expanding my Flash MX knowledge by going through some of the Kirupa tutorials. After completing the Random Letter Cycling tutorial I got an idea of how to modify it. The problem is I don't have a good grasp on writing my own Actionscript yet to try my idea.I can create a single instance of the movie clip (clip1.fla) but I am unsure of how to tie together multiple clips to create my desired idea (example.swf)Does anyone have the time to give me some pointers of how to achieve effect in the attached file? It's based on the tutorial above, but after it runs , it fades out and repeats itself a couple times. Ideally I would like each item to appear for about 2-3 seconds, fade out, and have the new one appear

I created a somewhat custom Spark button by doing the File > New > MXML skin and basing it on spark.components.button. The problem is that I need to add an extra text field to the button component and dynamically change that text...but of course, the property isn't recognized on a Spark Button.
Is there a simple way to add this field to my custom button skin & its property so it can be addressed? If not, is there a simple way to take what I've done and just extend the Spark Button? I can't seem to find any examples that show how to do it without writing it all up in ActionScript.

I've an Accordion component in my Flex application and works great, but I found a little glitch in its behaviour.While one of its menus is opening, it shows a white rectangle and, when it completely loads, it shows me the content. But I want to show the whole content without this "white" rectangle when it loads.For example:
Image 1: My Accordion is ready to use
Image 2: I want to open another submenu, so while it's opening, a white rectangle is shown (I was really quickly to take an screenshot)
Image 3: Recently opened submenu is fully loaded.Here is my source code:
<mx:Accordion id="accordion" width="100%" height="90%" verticalGap="0" horizontalGap="0" creationPolicy="all">[code]...........

The thing is, at this moment I have to modify the text file variables and then upload this last again and again. The file with variables could be a XML file too.

I have a result screen that shows bonus points and such. I want each text field to increment one after another and also have it increment by a certain amount each frame. Result Screen pops up. First is the player score check the player score, is it more than the score we want to display if the player score is greater than the player display score by 100 increase the player display score by 100 if the player score is greater than the player display score by 10 increase the player display score by 10 else increase the player display score by 1 when finished move to the next score...and so on. I have thought of using timers to move from one score to the next, but not being in an Event.ENTER_FRAME it only does one if then moves to the next one.
Also the if statement for incrementing the score looks ridiculous and I'm thinking there has to be a better way to do it. I was thinking of making it a separate function but then I wouldn't know what to return, or how to return it so it looks like its increasing and not just showing the total number instantly. I'll try to expand on it a little more.

Ok.. so here's the basics of the code:
ActionScript Code:
var stackNum:TextField = new TextField();
stackNum.everythingcondensedhere = everythingcondensedhere
stackNum.type = TextFieldType.DYNAMIC;
[Code]....
It creates a textfield (and an image, but not important) and a movieclip, adds the MC to the stage and adds the image(itemLoader) and the textfield(stackNum).
And then it adds it to an array at [x][y].
Then later it calls the .stackSize, adds 1 to it, and tries to update the textfield.
Everything works except for updating the textfield, I just can't figure out what I need to use to point to it and have it change.

I have a .fla which loads 2 swfs. Each swf plays an animation. I only have the .swfs and not the .flas so I cannot add code to the animations themselves. I want the 2nd swf to play when the first is finished. Is it possible for my .fla to monitor the first loaded clip for when it ends and then play the second one.

OK, from what I know actionscript in Flex runs asynchronously. I need the ability to run a method in a loop synchronously. Consider this code:
public class CustomerContainer extends VBox
{
public function CustomerContainer ()
{
[Code]....
This is not my exact situation as it is a bit more complicated to explain here. There is an abstract class and several custom view objects derived from it. Some of the views are dependent on others being completed first but I cannot seem to order them in the correct order. TIMERS are not an option. Probably not explaining this correctly.
