[flexcoders] Programming Challenge - finding nodes in an array with a value near a number
So I've got a programming challenge.
I've got audio/video streaming in, and I've got an XML document
converted to an Array (each node is an index of the array), each
value in the array in the contains a cuepoint in Ms.
What's the most efficient way to find the cuepoints in the array
which are within range (with a fuzziness of say +/- 50ms) of the
current position of the playhead on my audio/video?
At the moment I've simply got a for (var i:Number = 0; i
cuePoints.length; i++) {}
That's not really a robust way to check the array of cuepoints for
matching values of the current media's playhead position - as the
more cuepoints in the array, the lower the chance is of finding
matches accurately.
So to reiterate - say my media's playhead is at a position of 2300Ms.
My swf is 30FPS - and in my onEnterFrame for the mediaplayer in that
SWF I check to see if there are any cue points (with values of say,
2250, 2300, 2325) within range of the current playhead position.
I'm hunting for the most efficient way to achieve that.
I've got some ideas - which will work ok - but this has to be a
common programming challenge - and there has to be a more efficient
way than a loop through an array reading all cue point values that
are within range of my current playhead's position.
Have at it - homies.

[flexcoders] using coldfusion to return height and width of flex swf
I've got a SWFTag coldfusion tag I've made that's a handy shortcut for embeding flash 8 or less swfs into a page with syntax that feels similar to an an HTML image tag. Unfortunately, it requires that I know the explicit width and height of the swf, and set them as attributes. SWFTag uses SWFObject at present, and, as such I've had little success getting SWFObject to embed a flash 9 flex published swf onto the page. I've low-jacked the generated HTML Template from Flex, and incorporated it into my SWFTag, so if it's a flash 9 SWF, it uses the a massaged Flex HTML Template - but that still requires that I a) tell the custom tag that it's a flash 9 swf, and 2) know the height and the width. Ideally, I'd like to let developers just type the equivolent of skin:SWFTag source=/swf/mySWF.swf/ and leverage coldfusion to somehow magically read in the version of the SWF, and its width/height. I had a bit of a look into the CFXImage tag - but it doesn't seem to support SWFs. So - anyone got any clues about the potential magic that is Adobe owning Flex, Flash and ColdFusion so they'd provide some sort of mechanism for me to read in version and dimensions of SWF files on the server? Let me know if I'm reaching - I'm trying to include a buncha Flex 2.0 optional components into the lastest version of the ColdFusion Content Management System FarCry - which is produced at the place I work. The easier I could make it for developers/clients to use swfs, the better it'll be for the company I work for, and Adobe. Come on Mike Chambers - etc - you boys have gotta have some tricks up your sleeve that I haven't found after hours of googling :D Reargards, Grae Hall Senior Designer www.daemon.com.au
[flexcoders] Re: ToggleButtonBar: Styling Individual Button
Hey hey hey, I had just such a question, so I spent a bit of time looking into how to access the child buttons of a button bar, and skin them uniquely, as opposed to simply skinning the first - rest - and last. I figured out how to do it, and ran a cool looking custom skin over the top of it, but I don't have the screenshot, or code handy (I'm at work). I used an extended button bar to display the steps of a wizard process, with the current step of the wizard being visually referenced by the accompanying step name on the button bar. I had the entire skin customised - semi-3d looking square blocks of different colours with big numbers on each. I'll post the code for it tomorrow, as well as a screenshot of it working. It is possible, it's a little tricky as you have to access the the child a bit differently to how I expected. Here's a href=http://grae.halltech.com.au/media/uiruntimeskin.jpg an earlier example/a I was working on, where I overrode the skins of various uicomponents at runtime with programmatically drawn skins. img src=http://grae.halltech.com.au/media/uiruntimeskin.jpg / and, in case the list strips out the html, here's a text link to it. I'll post a useful, commented, and flexible example for you tomorrow night.

[flexcoders] success: flex data services linking to coldfusion - both as instances in jrun
after a lot of stuffing about today, Patrick and I managed to get FDS running as an instance of jrun, configured apache, and got FDS talking to coldfusion's event gateway, which did ran logic on the consumer/producer messages, and supplied the result. We couldn't find much in the way of specific documentation about how to get that done - but we worked it out. I'll post some sample code at the end of next week - as the FDS stuff for Flex is the backbone of our Australian Flex Derby competition entry - which closes in a few days. But hell yeah, pushing and pulling information between two separate people through the browser, while running logic on it through cfc's on the cf server.

[flexcoders] Limiting length of xmllistcollection to display only first 10 in a datagrid.
I've got a datagrid component which I'm using to display the most recent documents from an XML file. It's an XMLListCollection. I think. I've worked out how to do the sort()/refresh() stuff on it, and that's working as expected. However, there's the potential for there to be in excess of 1000 documents references in the XML file. I'd like to limit the xmllistcollection I use for my recent documents to a set number - I'm just unsure of the syntax. I tried iterating through the XMLListCollection with a for i ++ loop, starting 'i' at the number I wanted - and then removedItemsAt(i) - but that appears to have affected the other XMLListCollection I use, of the same XMLList - to search all of the documents. So instead of getting back a lot of results, in my other datagrid component based on search, I only get back a maximum of whatever I set 'i' to in the for loop on the recent documents. So - how do I limit my results, and how do I interact with XMLListCollections properly so that I don't change the loaded XMLList underneath, that's referenced in other XMLListCollections? Your help in this regard - my fellow flex monkeys, would be greatly appreciated. If I check mail-archive in a month, and see that this, like many useful questions posed on this list, received no replies, I'll feel quite despondent. True story.

[flexcoders] Re: Programmatic skinning example - buttons, buttonbar, panel, etc
Hey hey, I've never actually published any of Flex apps to the web before, so it's entirely possible I made some sort of retarded mistake. I've got a lot of embeded SWF files in there - for fonts, and graphics, which work for me, but maybe it's because it's using my local permissions and not reading it fully independently off the web. It's in Beta 3.0, so, it uses the Flash 9.0 beta - what problems are you coming up with exactly? I'd really like to ensure it actually works for everyone, otherwise there wasn't much point working on it and publishing it. Which version of Flash player are you using, and what sort of browser? I've only tested it in IE - so I don't know if it loads in FireFox etc. Let me know - it's important to me that it works.

[flexcoders] Extended Visual Component Defaults in Design View
I've created a series of extended visual components for the project
I'm currently working on so I've got a centralised location to adjust
the appearance and methods of any component I put on the stage.
So for example, I have XPanel, which extends Panel, and I've
overridden commitProperties to set a series of defaults such as
borderThickness, etc.
It seems to work fine when I run the application, but none of the
defaults appear in Design View. The component can be dragged onto the
stage etc, but the properties that appear in the Design View are the
Flex defaults, not the new defaults I've set.
Where or how exactly do I set the properties within the extended
class to enable Design View to pick them up and display them?
Here's an example,
package xmx.comps {
import mx.containers.Panel;
import flash.util.trace;
import mx.states.SetStyle;
public class XPanel extends Panel {
public function XPanel() {
super();
var className:String=XPanel;
}
override protected function commitProperties():void {
layout=absolute;
setStyle(cornerRadius, 0);
setStyle(headerHeight, 24);
setStyle(borderThicknessBottom, 0);
setStyle(borderThicknessLeft, 0);
setStyle(borderThicknessRight, 0);
setStyle(borderThicknessTop, 0);
setStyle(borderThicknessTop, 0);
setStyle(headerColors, [0xFF,
0xFF]);
setStyle(highlightAlphas, [1,1]);
setStyle(backgroundAlpha, 0.3);
setStyle(backgroundColor, 0xFF);
setStyle(dropShadowEnabled, true);
setStyle(shadowDirection, right);
setStyle(shadowDistance, 1);
super.createChildren();
}
}
}
and the MXML that instances it is as follows,
xmxComps:XPanel x=9 y=9 width=234 height=474
id=panelTest
/xmxComps:XPanel
It appears as expected when the application is run, but it looks like
a standard Flex panel in Design View.
Is there a simple fix, or am I doing something horrendously incorrect?

[flexcoders] F2B2 : RE: Extended Visual Component Defaults in Design View
I've cleaned it up a little - and rectified my main mistake - after
reading some more documentation I've set the defaults in the
constructor.
I've not yet been able to figure out how to have those defaults
present in the design view, yet. So, any help would be appreciated.
This is my updated code,
package xmx.comps {
import mx.containers.Panel;
import flash.util.trace;
public class Panel extends mx.containers.Panel {
public function Panel() {
super();
layout=absolute;
setStyle(backgroundAlpha, 0.3);
setStyle(backgroundColor, 0xFF);
setStyle(borderAlpha, 1);
setStyle(borderColor, 0xFF);
setStyle(borderStyle, solid);
setStyle(borderThickness, 1);
setStyle(borderThicknessBottom, 0);
setStyle(borderThicknessLeft, 0);
setStyle(borderThicknessRight, 0);
setStyle(borderThicknessTop, 2);
setStyle(color, 0x33);
setStyle(cornerRadius, 0);
setStyle(fontSize, 10);
setStyle(headerColors, [0xFF,
0xBB]);
setStyle(headerHeight, 21);
setStyle(highlightAlphas, [1,1]);
setStyle(dropShadowEnabled, true);
setStyle(titleStyleName, fontBodyB);
}
}
}
and the MXML is as follows,
xmxComps:Panel x=9 y=9 width=234 height=474 id=panelTest
title=Panel Test
xmxComps:Button x=3 y=3 label=Button/
/xmxComps:Panel

[flexcoders] F2B2: Loaded SWF Movie Clip frame as unique image source?
How's that subject for correct grammar for phrasing a question. So - what I've been trying to do - I load a mulitframe external SWF in via with the Loader - then once loaded I create a new movieclip from the loader.content - then I gotoandstop on my desired frame - then it gets a little bit sketchy, because I don't really know if I can assign the contents of that movie clip to the source of an image. The reason I'm trying to do that, is so that I can have a multi- framed SWF, with each frame containing various assets, that I can then place into some sort of display object (either image, or another movieclip) for use in my user interface. The two main stumbling blocks to date have been that if add a movieclip that's stopped on a certain frame of a loaded swf, then make a new movieclip from and stop it on another frame, all of the movieclips change to the new frame I wentto in the multi-framed swf. Short of copying the contents of the movieclip object out to bytecode and then writing it back in as a bitmap or something, I can't really seem to get it working. The second stumbling block is I'm unsure of the syntax or the feasibility of assigning the contents of a movieclip and the frame its on to an Image, and then creating another image, changing the movieclips frame, and then assigning that frame to the newly created image, giving me to images that are different frames of the same swf. My current workaround is to load the swf in from scratch per frame I require - hardly graceful but until I've got a better solution I'm running with it - and hoping caching will make up for my shortcoming. It does work though. So - can I do it? Can I have a loaded multiframed swf in a movieclip that I set to a frame, and then assign that frame out to a unique image, rinse/repeat allowing me to load the swf once and spit out all of its frames to unique displayobjects? The groups input would be greatly appreciated - well - provided the input isn't read the help page for the x class to find that the x class entry in the documentation contains nothing other than TBD.

[flexcoders] Timer problems - timer still firing once after timer is reset.
I'm having a bit of a problem with the Timer function. And I'm also a
little unsure of the variable syntax to read the framerate of the
application.
I've created a custom class to allow me to easily attach listeners and
actions to components throughout my application in a centralised manner.
I've used a timer that's set to fire once per frame - which is worked
out by dividing 1000 miliseconds by the application's framerate.
Although at the moment I'm setting the framerate manually as I can't
quite figure out how to reference the application framerate dynamically.
My main problem is - that after I call a timer.reset(); before the
Timer has completed it's currentCount - the timer still fires one more
time.
I've tried a few things - had a bit of a stab at using
stopEventPropegation etc - but the syntax for that was odd and it never
worked. I tried putting in a condition for timer.running before the
actions I wanted to occur would be run - but the timer reports running
as true for one instance after I reset - not as soon as I reset it.
My code is here - it's unfinished, and has had a few things stripped
out for simplicities sake - but it should demonstrate what I'm trying
to acheive.
override protected function createChildren():void {
timer = new Timer(singleFrame, eventCeil);
thisEventCeil = eventCeil;
addListeners();
}
private function addListeners() {
switch(listenerType) {
case mouse:
listenerTarget.hitArea = listenerHitArea;
listenerTarget.addEventListener
(MouseEvent.MOUSE_OUT, funcOutOverDown);
listenerTarget.addEventListener
(MouseEvent.MOUSE_OVER, funcOutOverDown);
timer.addEventListener(TimerEvent.TIMER,
timerTick);
break;
case key:
trace(Key Listener Type);
break;
}
}
private function funcOutOverDown(event:Event):void {
thisEventType=event.type;
if (timer.running) {
timer.reset();
trace(terminated timer from event listener: +
lastEventVal);
lastEventFloor = thisEventFloor;
thisEventCeil = eventCeil - thisEventFloor;
}
switch(thisEventType) {
case mouseOut:
thisEventEaseCeil = 1;
thisEventFrom = 0;
thisEventTo = 1;
timerInit=true;
break;
case mouseOver:
thisEventEaseCeil = undefined;
thisEventTo = 1;
thisEventFrom = 0;
timerInit=true;
break;
}
if (timerInit) {
thisEventFloor = 0;
timerInit=false;
timer.start();
}
}
private function timerTick(timerEvent:TimerEvent) {
trace(timerEvent);
if (timer.running) {
thisEventFloor = timer.currentCount;
thisEventVal = EasingLib.easeInCirc
(thisEventFloor,thisEventFrom,thisEventTo,thisEventCeil,thisEventEaseCei
l);
lastEventVal = thisEventVal;
if (thisEventFloor = thisEventCeil) {
trace(completed timer: + lastEventVal +
+ thisEventFloor);
timer.reset();
lastEventFloor = thisEventFloor;
}
}
}
The problem is - if I get an out or over event before the timer is
complete - which successfully resets the timer - it still passes the
timer.running condition.
That's annoying me - and I'm really not sure how to stop it from
occuring.
That's really the only problem I'm having at present with the code you
see - everything else seems to behave as I require it. Before I can
expand it out to cover more conditions and listeners I really need to
get a handle on the timer's behaviour.
I figured that getting the timer to fire once a frame and then process
my actions would be a nice non-CPU intensive way to handle my various
actions, animations etc.
I'd appreciate any input.
Cheers.

Pretend the thisEvent=eventCeil; line exists before I refer to

Although at the moment I'm setting the framerate manually as I
can't
quite figure out how to reference the application framerate
dynamically.
My main problem is - that after I call a timer.reset(); before the
Timer has completed it's currentCount - the timer still fires one
more
time.
I've tried a few things - had a bit of a stab at using
stopEventPropegation etc - but the syntax for that was odd and it
never
worked. I tried putting in a condition for timer.running before the
actions I wanted to occur would be run - but the timer reports
running
as true for one instance after I reset - not as soon as I reset it.
My code is here - it's unfinished, and has had a few things
stripped
out for simplicities sake - but it should demonstrate what I'm
trying
to acheive.
override protected function createChildren():void {
timer = new Timer(singleFrame, eventCeil);
thisEventCeil = eventCeil;
addListeners();
}
private function addListeners() {
switch(listenerType) {
case mouse:
listenerTarget.hitArea = listenerHitArea;
listenerTarget.addEventListener
(MouseEvent.MOUSE_OUT, funcOutOverDown);
listenerTarget.addEventListener
(MouseEvent.MOUSE_OVER, funcOutOverDown);
timer.addEventListener(TimerEvent.TIMER,
timerTick);
break;
case key:
trace(Key Listener Type);
break;
}
}
private function funcOutOverDown(event:Event):void {
thisEventType=event.type;
if (timer.running) {
timer.reset();
trace(terminated timer from event listener: +
lastEventVal);
lastEventFloor = thisEventFloor;
thisEventCeil = eventCeil - thisEventFloor;
}
switch(thisEventType) {
case mouseOut:
thisEventEaseCeil = 1;
thisEventFrom = 0;
thisEventTo = 1;
timerInit=true;
break;
case mouseOver:
thisEventEaseCeil = undefined;
thisEventTo = 1;
thisEventFrom = 0;
timerInit=true;
break;
}
if (timerInit) {
thisEventFloor = 0;
timerInit=false;
timer.start();
}
}
private function timerTick(timerEvent:TimerEvent) {
trace(timerEvent);
if (timer.running) {
thisEventFloor = timer.currentCount;
thisEventVal = EasingLib.easeInCirc
(thisEventFloor,thisEventFrom,thisEventTo,thisEventCeil,thisEventEaseC
ei
l);
lastEventVal = thisEventVal;
if (thisEventFloor = thisEventCeil) {
trace(completed timer: + lastEventVal
+
+ thisEventFloor);
timer.reset();
lastEventFloor = thisEventFloor;
}
}
}
The problem is - if I get an out or over event before the timer is
complete - which successfully resets the timer - it still passes
the
timer.running condition.
That's annoying me - and I'm really not sure how to stop it from
occuring.
That's really the only problem I'm having at present with the code
you
see - everything else seems to behave as I require it. Before I can
expand it out to cover more conditions and listeners I really need
to
get a handle on the timer's behaviour.
I figured that getting the timer to fire once a frame and then
process
my actions would be a nice non-CPU intensive way to handle my
various
actions, animations etc.
I'd appreciate any input.
Cheers.

[flexcoders] Re: Timer problems - timer still firing once after timer is reset.
Well - fortunately the request for thoughts on the timer can be disregarded - I've managed to get it all working. The application now has a custom class able to be attached to any interface component which tweens from a user defined value to a user defined value with a user defined easing type. If related listener events are fired while a tween is in progress, the class tweens back from the current value to the destination value defined in the most recently fired listener - in the same number of frames it took to get to its current value. I had no luck with this basic type of interface functionality using the native flex classes - which is a little disappointing. I'm still having difficulties getting the value of the application framerate. So any tips there would be appreciated. -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

[flexcoders] Re: Flip and mirror a bitmap in Flex
The issue is it doesn't have the image loaded completely and added as an instance - so - you need to get a set of loader listeners for the image happening - and then on the completion listener run the bitmap reflect function. If you embed the image - you should be sweet. At least - that's what I remember. I haven't got Flex or Flashplayer 8.5 on this PC, so I can't be certain it's not already embeded. :D I've got bitmap filters running on run-time loaded images using the bitmap classes etc in an app I'm designing/developing at the moment - so I know it works. --- In flexcoders@yahoogroups.com, Michael Schmalle [EMAIL PROTECTED] wrote: Hmm, I was using FireFox.

[flexcoders] Re: Flip and mirror a bitmap in Flex
Dearest Richard, There's a demo of run time reflection of flex components by Trey Long located here http://humanwasteland.com/reflectdemo/ReflectFilterDemo.html it's a good example of how to implement the bitmap, bitmapdata, and matrix classes in Flex 2.0 It's a bit technical - but you can view the source and download it. As far as I'm aware - I've not seen a simplified flip/mirror function in Flex - the class that does the flip in that example is matrix.scale where he puts (1, -1). Have a play around with it - I learned a bit from it. --- In flexcoders@yahoogroups.com, Richard Schutten [EMAIL PROTECTED] wrote: Hi there, Are there standard flip and mirror routines that can be applied in Flex 2 for bitmaps?

[flexcoders] Looking for simple working Flex 2.0 remoting examples
The Flex project I'm working on is up to the stage of commencing initial communications from flex swf client to the business logic on the backend server. I've got a subcontractor working with me and I've handed him the task of getting the remoting functional. Unfortunately we haven't been able to find any working examples of Flex 2.0 remoting. The backend that we're tying our front end into is running WebOrb - we've seen a proof of concept in Flash of the client requesting methods on server classes through remoting and recieving objects and arrays as results returned from the server. We're at least sure that we're connecting via AMF through Remoting, rather than SOAP, or an HTTP service. We're just not sure where to start - or where to start researching - implementing the remoting functionality in Flex.

[flexcoders] application MXML loading children component MXMLs
I'm writing the foundations of an ecommerce site in Flex. I've created an application MXML as the stub with the application tags - and I've created the major subsections as MXML components framed by canvas tags. What's the best method of including the component MXML files so that data can be shared with relative ease throughout the application, whilst still allowing a modular stub/children structure? I've had a bit of a tinker in the flex store - and it seems to use Actionscript to call the component MXMLs with a fileName.function() style method - I'm trying to toss up the easiest, quickest and most robust way of linking all of my separate bits together. It's a bit of an amateur question :D -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

[flexcoders] syntax / code hinting help for a custom classes 'type' variable
I'm extending the effects class to allow me to have a custom tag that can tween a component in a known and limited number of ways. I'm not really sure what the correct syntax is to define those limited types of class methods. Say my tween class allows you to tween the alpha, the scale, and the coordinates of a designated item on the stage. So, I'm not sure how to define a variable in my class called tweenType so it consists of 3 potential values named alphaFX, scaleFX and coordFX, with one of them being a default. I'd also like to be able to type myMX:effect tweenType=alphaFX... and it code hint the known values of the variable in the class. I'm not really sure what sort object/variable is the correct one to use in AS3. Any help would be greatly appreciated - etc. -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

[flexcoders] Removing Default Halo Themes
I've tinkered around most of today - read quite a bit - and I'm not really sure if I'm on the right track. In my default Flex app the components are obviously pre-styled with one of the Themes. As part of a fairly interesting contract I'm working on - I'd like to specify the styles of my components myself - programmatically through stylesheets. I'm becoming more aware of how much I have to unstyle what seems to be the existing default theme. For instance - with Flex Style Explorer, button components have a nice bevel. The manuals seem to indicate that the default theme doesn't allow you to control that aspect of the button component. Ideally I'd like to create the styles either via stylesheets, or programmatically through the drawing API (although - lord knows I'm oblivious to the syntax required to take Kevin Hoyts accordian example and apply that style of director skinning to a button component). Is there a way to set the themes to close to nill - so I can work my way up from there? And - is there a decent example of succesful reskinning of a button component to be found on the interweb? After I crashed explorer by freestyling Kevin's Example and attempting to extend the button class - I'm cautious with how I'll proceed. I'd prefer to work with the stylesheets and drawing API - I'd like to replicate this base button shape http://grae.halltech.com.au/media/ui_icon_ok.gif - and create my own custom button components which I can then pass glows, blurs, etc over. I had a crack at the 9slice - the 9slice accordion skin prior to Kevin's demonstrated some issues with masking non-square shapes. Here's hoping I'm on the right track. - Grae -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
