[flexcoders] Re: Is there a way to detect whether a TextLine is partially cut-off (vertically) in TLF?
I figured it out:
var lastFullyVisibleLine:TextFlowLine;
for (var i:int = textFlowComposer.numLines - 1; i = 0; i--) {
lastFullyVisibleLine = textFlowComposer.lines[i] as TextFlowLine;
if (lastFullyVisibleLine.textLineExists lastFullyVisibleLine.y +
lastFullyVisibleLine.textHeight = height) {
break;
}
}

Say you had a container that was 15px tall, and each TextLine was 10px high

partially visible, TLF would mark it as visible. Anyone know if there is a
smart way to detect when a TextLine is vertically clipped?

Re: [flexcoders] Manual TextFlow + Embedded Font not supported?
My examples work in Flex 4.5.1, and monkey patching is not straightforward
based on my Googling. Looks like no way out without upgrading.

of textFlowLine.getTextLine().textBlock.dump(), TLF is just not
aware/registering the font until after the container is rendered.

If you run it, you will notice 4 RichEditableTextContainers. The first two
use device fonts (Courier and Arial), and they are interpreted correctly.
The trace of the dump() in the console shows this nicely. The third box, in
red, is the problem. This box tries to employ an embeded font before the
container is rendered, and if you look at the trace, it's not accepting the
font and instead using the default Times New Roman. The fourth box is
exactly the same as the third box, but solves the problem by applying the
truncation at updateComplete, rather than on initialize. The trace shows the
font to be correct as well.
Do you think all this is related to contexts and multiple swfs as you
describe in your blog?
Thanks!
What do you make of this? Is there a way to mimic what happens to textFlow
on updateComplete but inside initialize?

[flexcoders] How to make a s:Label with variable content wrap, without specifying width=100%?
I have a s:Label in an ItemRender whose content is variable in length from item to item. This label also has a ToolTip defined that gets displayed when a user hovers over the text. I would like for this label to wrap and adjust to the browser size, but I don't want to specify width=100% because then the tooltip displays when hovering over empty space. Anyone know of a clever solution? Thanks!
Re: [flexcoders] Highlight keywords in a block of text using TextLine
Is it possible to use mxml tags like RichEditableText or TextArea whose content is already populated as the source for this process? What would we get from them, TextLine's? TextBlock's? This is a lot more challenging than I thought it would be :)
Re: [flexcoders] Highlight keywords in a block of text using TextLine
Thanks a lot for your input guys. Nice example Andriy, but the viewsource
link is dead.
I think I found the simplest way of doing this: setFormatOfRange()
It basically changes the format (background/foreground) of a range of
characters in a RichEditableText component. So all I have to do is (from
inside RichEditableText):
var highlightFormat:TextLayoutFormat = new TextLayoutFormat();
highlightFormat.backgroundColor = 0xffee66;
var keywordsArray:Array = model.keywords.toLowerCase().split(' ');
var indexOfKeyword:int = 0;
for each (var currentKeyword:String in keywordsArray) {
while((indexOfKeyword = this.text.toLowerCase().indexOf(currentKeyword,
indexOfKeyword)) = 0) {
this.setFormatOfRange(highlightFormat, indexOfKeyword, indexOfKeyword +
currentKeyword.length);
indexOfKeyword++;
}
}
Clean.
Re: [flexcoders] Highlight keywords in a block of text using TextLine
Oh Andriy I just realized what you suggested is the same thing, just on a RichText through editManager.applyFormat - very nice. Baz

[flexcoders] Highlight keywords in a block of text using TextLine
I have a search and results page that I would like to highlight the keywords
that were searched for, in the text of the results. It was suggested that I
use TextLine for this, but I am having trouble figuring out how to make it
work. I started a simple, compilable dummy application and was hoping
someone could give me some tips on how to continue:
?xml version=1.0 encoding=utf-8?
s:Application
xmlns:fx=http://ns.adobe.com/mxml/2009;
xmlns:s=library://ns.adobe.com/flex/spark
xmlns:mx=library://ns.adobe.com/flex/mx
initialize=initApp();
fx:Script
import flash.display.Sprite;
import flash.text.engine.*;
private var textLine:TextLine;
private function initApp():void {
var normalFormat:ElementFormat = new ElementFormat(null, 12, 0x00);
var highlightFormat:ElementFormat = new ElementFormat(null, 14, 0xff);
var textBlock:TextBlock = new TextBlock(new TextElement(This is text that
has KEYWORDS. I would like to highlight these KEYWORDS by changing their
font color and adding a light yellow background graphic., normalFormat));
textLine = textBlock.createTextLine();
textLine.y = 100;
embeddedFontHolder.addChild(textLine);
}
/fx:Script
mx:UIComponent width=100% id=embeddedFontHolder /
/s:Application
Anyone have any ideas?
Cheers,
Baz

Alex, thanks a lot for the tip, TextLine is VERY interesting and I've been researching it a lot. I'm surprised not to have bumped into a plug-and-play HighlightComponent that someone's released, so I guess I'll have to roll my own. I'm not sure exactly where to start though. Do I use atoms? How do I get at a RichEditableText's TextLines, it sems only available in TextArea? Should I use TextFlowComposer? What would the general anatomy of a HighlightComponenet look like? Thanks!

Thanks Oleg. You are helpful as usual. I want to mimic HTML in how a link is selectable, yet still clickable with the hand cursor.

[flexcoders] Having trouble justifying Flex to the higher-ups... It only seems to be appropriate for media based sites...
We are building a text-based app that searches records in a database then displays the results on a page using an ItemRenderer type deal. We want to include some niceties like infinite-scroll - where a user would simply scroll down and subsequent records would load automatically in the background - and intelligent feedback - where different elements on the page animate in some way to show progress or activity. These can be accomplished easily using either Flex or AJAX. My superiors, and admittedly myself, are having trouble justifying using Flex to implement this. Some reasons: - Text is not properly selectable (unless you put everything in one huge/ugly/unfeasible TextInput block) - Text is not findable using the browser's CTRL+F - Text is not properly/nicely indexable by search engines - Slower to render than HTML (as fast as it is, it is still slower, more to load, etc) - Inferior mobile experience (I tested 10.1 on my Nexus One, and it's very good, but still far worse (for text/scrolling) than simply using HTML in the native browser (which has built-in scrolling, flicking, and zooming, with zero additional effort, while Flash doesn't). If you do any research for whose using Flex in public applications, you will only find media based sites like: - picnik.com (photos) - beatport.com (mp3's) - mixbook.com (photos) - mastercard.com (only a configurator sub-element) - ANYTHING VIDEO I am having trouble seeing the benefit of using Flex for anything non audio/visual related. Besides the advantage of it being cross-browser/cross-platform, is there any compelling reason to consider Flex for this app rather than HTML/AJAX? Cheers, Baz
Re: [flexcoders] Having trouble justifying Flex to the higher-ups... It only seems to be appropriate for media based sites...
Thanks Oleg. You confirmed my suspicions. You are right that Flex/Flash performs very well for exactly the type of site you referenced (pixlr.com). I can affirm though, that it does not perform great with text heavy activities - especially if we are talking about RichEditableText with the span and b, etc - even excluding discussion of load times and such, just runtime performance is flickery, choppy, etc. I guess I have to master JQuery now, sad... I love Flex.

[flexcoders] Is it possible to disable automatic re-positioning of viewports when associated with a Scroller?
If you implement the Scroller (or VScroller) in a non-standard way as a
separate entity (i.e. NOT surrounding the object you want to scroll) then
manually assign it's viewport to the object that needs to be scrolled. The
scroller automatically changes the size and position of it's target object.
Is there a way to disable this?
Some non-tested example code:
s:Application
s:Scroller top=0 viewport={myViewPortObject} /
s:Group id=myViewPortObject top=500 /
/s:Application
In this example, the top=500 of the Group is not respected and instead
automatically shifted to fit into the positioning of the Scroller (top=0).
I would like for the Scroller to ONLY provide scrolling capabilities
regardless of where I decide to place the viewport, without having to extend
it - something like disableAutoPositioning=true - is this possible?
Thanks,

Re: [flexcoders] Re: Thoughts on Flash by Steve Jobs
The best part is that HTML5 video is going to be based on H.264 - which is not only a proprietary codec, BUT COSTS MONEY! At least flash is free. Here's an excerpt of what happened with gif: The web in 1999 was a lot smaller than it is today, so a lot of people don’t remember what happened back when Unisys decided to start to enforce their GIF-related patentshttp://en.wikipedia.org/wiki/Gif#Unisys_and_LZW_patent_enforcement. GIF was already widely used on the web as a fundamental web technology. Much like the codecs we’re talking about today it wasn’t in any particular spec but thanks to network effects it was in use basically everywhere. Unisys was asking some web site owners $5,000-$7,500 to able to use GIFs on their sites. Note that these patents expired about five years ago, so this isn’t an issue today, but it’s still instructive. It’s scary to think of a world where you would have to fork up $5000 just to be able to use images on a web site. Think about all of the opportunity, the weblogs, the search engines (even Google!) and all the other the simple ideas that became major services that would never have been started because of a huge tax being put on being able to use a*fundamental* web technology. It makes the web as a democratic technology distinctly un-democratic. from ( http://www.0xdeadbeef.com/weblog/2010/01/html5-video-and-h-264-what-history-tells-us-and-why-were-standing-with-the-web/ )
Re: [flexcoders] Re: Thoughts on Flash by Steve Jobs
There are 2 distinct and separate anti-Adobe issues from Apple.

So just to be 1000% clear, you write code in AS3, then the compiler outputs a pure iphone binary - there is no Flash, no runtime, no swf - nothing. So my question is, how would Apple even know what tools I used to create an app? What if I made my own code generator in objective C, is that allowed? Are they also going to say I'm not allowed to use notepad to write my code?

Re: [flexcoders] Re: Flebuilder 3 manage project
In my book, there are only 2 options for source control: GIT and Subversion. The main difference between them is that GIT is distributed and SVN is centralized. The future is with GIT, but SVN is more prevalent and its tooling more refined. If I were you, learning a whole new system, I'd go with GIT - it's really much, much, much better, and the eclipse plugin (eGIT) has been maturing very well. In terms of setup, it will only be a few hours for either one, but it will take some effort and reading - neither are totally point and click. Depending on your corporate policy, I'd just pay a couple of bucks a month for a hosted solution at somewhere like github.com. That's where all open flex projects are going and it's an unbelievably well put together site with TONS of help docs.

[flexcoders] Clean way to filter very large ArrayCollection (in pieces) using filterFunction
Hello, I have a very large arraycollection that users can filter by typing characters into a search box. I use ArrayCollection's filterFunction to perform the filtering, but as the recordset grows, it (obviously) takes longer to filter and makes the interface less responsive. Is there a way to access/adjust the internals of filterFunction without having to roll my own or implement greenthreading? Similarly, is there a way to know how far into the filtering it is, for example to update a Number of Matched Records box that gets updated DURING the filtering process rather than jst at the end when it is done? Cheers, Baz

Re: [flexcoders] Re: Honestly guys , at 48 should I expect Flex AS3 to change my life job wise?
There's a ton of Flex jobs in the States too. You don't even need a year, you just need 2-3 medium sized applications under your belt and you're good to go. Flex 4 is actually much easier than Flex 3. They replaced a lot of complicated and disjointed low-level code with much simpler, higher-level code constructs - especially when it comes to layouts, colors, and shapes. Don't use the drawing API in Flex 3 - that's going away - otherwise you are certainly not wasting your time with Flex 3. Once you get one simple Flex 3 app down, I'd jump into Flex 4 and continue from there. At my company we couldn't care less about age, sex or race. We have a lot of foreigners and people of varying ages - it would be nice to have a few more females but they don't apply!

Re: [flexcoders] Question about Flex Actionscript 3 code Flash actionscript 3 code
Hey, Flex is nothing more than a framework built using AS3, and AS3 only exists in the flash player, so they are the exact same AS3. An Flex (mxml) component, is just a set of AS3 classes, that you can modify, update, extend, or change in any way. Flex simply provides a high-level and convenient way to implement Action Script. To learn, I'd start with a simple mxml app, then as you progress, start adding more complexity and customizations. You will quickly find out that you will have to drop down to the lower-level AS3 code, by creating your own classes, or extending existing flex components. At the end of the day, to be a good Flex developer, you have to also be a good AS3 developer, so it's in your interest to learn both. Good luck!

[flexcoders] how light-weight is an array of custom objects if those custom objects already exist in another array?
Hi, I have an ArrayCollection of custom objects, and I need to create a subset of those custom objects based on a condition (without using the built-in filter() functionality). I am thinking of storing that subset in a second array, but that is not mandatory - performance is key in this piece of the app. If I did use a second array, how light-weight would it be, are arrays extremely effecient constructs in general? Also, in terms of the custom objects, I believe that they would all be linked by reference, and not duplicated in the second array - is this correct, and does that make the array basically the same as if it were storing simple integers? Overall, is this the most effecient way of getting a subset of an array? Thanks!

[flexcoders] Re: Text Effect: One Letter at a Time
I am thinking that I need to isolate the position of the specific letter, then create a new text element with that letter to animate then destroy. What do you guys think, is that the way to go? Is there a more efficient way? Cheers, Baz On Mon, Aug 31, 2009 at 10:56 AM, Baz li...@thinkloop.com wrote: Is it possible to apply an effect on a single letter in a textinput field? For example, when a letter gets typed (*change* effect), that letter expands and fades out. So if someone types a word, each letter of that word independently and sequentially expands and fades out as they are typed. Cheers.
Re: [flexcoders] Hierarchical Tree Data
Hey Wesley, when does the hierarchy get setup? Do you use an orm that builds and nests all objects - then, I guess, send that entire strucutre off to flex through remote object (amf). What do you get in flex, a nested ArrayCollection of objects, with a nested ArrayCollection of objects, indefinitely until all levels are fulfilled?

Here's the actual code, is it possible to replace this with one line of

of all keywords anywhere in any order';
var keywords:Array = ['UserProvidedKeyword1', 'UserProvidedKeyword2',
'UserProvidedKeyword3'];
var allKeywordsExist:Boolean = true;

[flexcoders] ItemRender - Access Specific Item at Run-time
I have a custom ItemRender that uses an ArrayCollection dataProvider. Everything loads up and displays nicely, but I am having a heck of a time finding out how to get at a specifc item in the list to change its state - something like myDataContainer.ItemArray[10].state = my_custom_state to get at the 10th item. Bear in mind its not the source ArrayCollection that I need to get at, that's no problem, its access to the components that get created from the ArrayCollection that I'm looking for. Is there a way? Thanks very much.
[flexcoders] Re: ItemRender - Access Specific Item at Run-time
I saw this info in another thread, and it makes sense, especially since I'm thinking of using virtualization: Renderers are virtual There's only as many renderers as you can see on screen plus one or two. If you have 1000 items and only see 8, there's only 8 to 10 renderers so indexToItemRenderer will return null for the other 992. It is better to simply iterate through the collection/dataprovider using So the question becomes, how do you change the state of a specific item? Should I add a column in my ArrayCollection called state and use that in the ItemRender?

Re: [flexcoders] ItemRender - Access Specific Item at Run-time
Thank you very much Tracy. What do you suggest to show/hide specific items based on an outside event? I am hesitant to *remove* the item from the ArrayCollection as I have to add it back at some point, maintaining the same complicated sort order. Currently my ArrayCollection contains a list of custom objects, would you suggest I had a property to those objects called *isHidden*, or something along those lines, and use that to set the state to hidden? Thanks a lot. On Wed, Aug 12, 2009 at 1:14 PM, Tracy Spratt tr...@nts3rd.com wrote: “access to the components that get created from the ArrayCollection… Is there a way?” Short answer, no. Longer answer: itemRenderers are recycled and only the visible renderers even exist. When using item renderers, any state that depends on the item/row must be driven by the item. You need to set up your renderer so that when an underlying item property changes, that change causes the rendered component’s state to change. You do this by overriding the set data() function and commitProperties function. Find an example of an itemRenderer and modify it rather than trying to do this from scratch.

Re: [flexcoders] ItemRender - Access Specific Item at Run-time
@Jake, I am implementing search-as-you-type, so there's a separate input box outside of the itemrender that needs to show/hide items that match or don't match what was typed in. I am using the *change* event of the search box. @Tracy, thanks for the suggestion, I tried that originally and it worked, but the experience was lacking because all items would disappear then re-appear on every key press. I would like for only the specific items affected to fade-out or fade-in when required. So far it seems adding an IsVisible property will work. When the input box *changes* I update the collection then invalidate the container's properties (or refresh the collection?). Depending on how that works out, I may or may not need to add commitProperties logic.
