[flexcoders] Bug in Flex Chart in Flash Builder?
I have created a simple chart in flex, if I resize the window by dragging the corner edge everything works. If I try to click a button and change the graph screen width and height via a state the Y scale of the graph resets to 0 through 100. When my data is between 0 and 3 obviously this doesn't work. The only way to fix it is reload the entire page which stinks for user interaction. I have asked this question before on this list with no answer - am I the only person hitting this or rather using flex charts and changing their size via a state? i.e. ...width.state1="100%" width.state2="250"... I capture the resize event and tried to invalidate the display list and refresh the data provider but nothing works. -r
[flexcoders] Problems getting a DataGroup to scroll
I have attempted twice to get a tileList of data in a DataGroup to scroll, here are my two attempts: ATTEMPT ONE: ATTEMPT TWO: So as you can see the first attempt was to use a skinnableContainer, and the second was to use a Scroller. What happens is the tileList layout works great but there is NEVER a scroll bar so that I can see all the data. What happens is as I resize and move the window around I can see more and more of the data but when the window gets a little smaller I miss data - is there something I am missing? -r
[flexcoders] Can someone point out a tutorial or sample about moving panels?
I was looking for a way to move panels freely within a container, like the tool on http://www.splashup.com/splashup/ and I was wondering how to do the same. I have no interest in duplicating the site, just want to know how to drop two or more panels into a container such that my users can move them about freely. (The thought being if you have a toolbar - you can let users select a button which in turn loads a module onto the container and then the users can move the modules as they wish on the container.) -r
[flexcoders] Chart Bug in Flash Builer?
Anyone else have this problem with charts in Flash Builder 4? - before making a bug submit I want to know if I am missing something. I place a chart into a panel - and as I drag the corner of the browser around, the panel resizes and the graph resizes. If, however, I add a button and then click it to set the panel width and height to 100%, the chart resizes the y-axis to an un-usuable number. i.e. the axis ranges between 1 and 5 during resizing, but when I click the button the axis becomes 1 to 100. Thus my data is smushed on the bottom of the page. I tried catching the resize event and invalidating the vertical axis along with refreshing the data sources. All attempts have failed. -ray
[flexcoders] Module help in flash builder
Does anyone know how to have multiple modules load inside a view stack in flash builder? So you have something like this: The problem is this - when the app first loads, the modules within the first navigatorContent show fine the others just load as a blank screen and do nothing. Now granted some of the modules may make the same restful interface call and flex doesn't enable anything to run in a thread like system but why can't I get the modules to load? I am not working on a web page but a real time monitor and control system and so to save bandwidth and memory I want to load and unload the modules based on which navigatorContent is active. I have googled and tried many solutions, all to no avail. I have resorted back to pulling out the code from the modules and adding them as direct components which works but isn't optimized. PLEASE HELP! -ray
[flexcoders] A way to animate or move a list smoothly? My attempt in Flex 3 works, Flash builder not so much.
I have a horizontal list of objects (image and labels) that I want to slide to the left smoothly, in a consistent speed till the last object goes off screen and then repeat. However my code, as seen below has two weird effects. First it hauls butt across the screen way to fast to be readable and second somewhere around the middle of the screen the speed jumps up a notch till the very end where it seems to slow down. Can someone point me to where I may be working the Move function wrong? xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" backgroundColor="0x00" preinitialize="preInit()" creationComplete="complete()">
[flexcoders] A way to removeAllChildren in a panel in flash builder 4?
Is their a flash builder 4 equivalent of ->
public function set dataItems(dataItemsCollection:ListCollectionView):void
{
//trace("set DataItems");
_dataItems = dataItemsCollection;
removeAllChildren();
rowsArray = [];
will removeAllElements() really achieve the same result - it just doesn't seem
to work right.

[flexcoders] Verticalscrollposition in flashbuilder?
Anyone know the equivalent of var scrollUpPropertyAction:AnimateProperty = new AnimateProperty(this); scrollUpPropertyAction.property = "verticalScrollPosition"; scrollUpPropertyAction.fromValue = this.verticalScrollPosition; in a panel for flash builder 4? In addition in flex you use to be able to turn on the scrollpolicy via the mxml tag like this - verticalScrollPolicy="auto" horizontalScrollPolicy="off" Is their an equivalent know in flash builder? -r
[flexcoders] ResultEvent from HttpService not parsing xml
I have an xml doc: Bob I have a Httpservice tage with url, resulthandler, faulthandler and resultformat="e4x". In my resulthandler, I have this: var ourXML:XML = event.result as XML; var name:String = ourXML.one.two.name; var x:int = 0; Here is the problem, I put a break point on the int assignment and look at the variables. I see that event.result AND ourXML both have the xml document in them but my name variable is empty. I even tried something like this - if (event.result.one.two.name =="Bob) and it fails. What are we missing? The debugger clearly shows the data is there but I can never seem to get it out.
[flexcoders] Flex 4 has radically changed my components
Any suggestions on the two idea's below (In Flex 3 it was easy and there is no samples yet that I have seen.) 1. Create an controlBar that is consisting of a list of 80x50 buttons with images and read in from an xml. i.e. xml document tells them the list of "buttons" to read in. 2. A list container that allows one to create a series of widgets that are say 200x400. The widgets are swf's on the server waiting to be loaded. If anyone has a real handle on this can you send me an email and we can chat offline - I want to upgrade to flash builder but I am dead in the water on these two concepts.
[flexcoders] https in flex 4?
can i make a simple call like this? https://127.0.0.1:8443/HalDS/hal/siteid"; result="siteID_resultHandler(event)" fault="siteID_faultHandler(event)"/> it should return an xml file like this - But I get stream errors when I issue the command siteID.send(); If I simply enter the url into my web browser it works.
[flexcoders] Question about the flash detection kit script
Can anyone give advice on how best to use the flash detection kit. My users have 4.0 minimum so I should be able to use the flash_AS_detection.as but I am not sure how to use it. I want to achieve the following: 1. My users go to page https://127.0.0.1:8443/initial/startPage.swf - if they are not the right flash then they are transferred to the page upgrade_flash.html (Which of course takes them adobe.) - how do I use the flash_AS_detection.as in a swf to achieve this? 2. If users are at right level then they are transferred to my swf - https://127.0.0.1:8443/Frank/rockOn.swf - again how do I add this to the startPage.swf noted in line 1. -ray
[flexcoders] Change TileList background color via actionscript
We have a TileList that when a user clicks a checkbox we would like to change the background color from white to red and backwards. Is this possible? Do we have to override a function because it doesn't seem like we can when we try to do it. We create a TileList using and then in a function we try to do something like list.backgroundColor.
[flexcoders] Change grid font size via actionscript?
We have a datagrid which we would like to change the fontsize of dynamically.
i.e.
private function increaseFontSize(): void {
table.fontSize += 4;
}
The problem is you can't do something like table.fontSize. At least it doesn't
work for me. I want to use a function so we can restrict the size increase and
decrease in another function.
[flexcoders] Progress bar in place over a component?
Is it possible to have several components inside a panel and as one of the components does something in the background can you place a progress bar over the component itself - NOT the whole page ?
[flexcoders] Multiple initializers for property 'dataProvider'
Below is a snapshot of one of my components. However I am always getting an error on the Datagrid (id="cmdTable') and the error is: Multiple initializers for property 'dataProvider'. (note: 'dataProvider' is the default property of 'mx.controls.DataGrid'). Does this mean you can't keep more than one datagrid or datagrid type in a file? Here is my source - http://www.adobe.com/2006/mxml"; xmlns:comp="components.*" width="100%" height="100%" backgroundAlpha="0.0" fontSize="14" initialize="init()"> thanks for the insights or help to solving this.
[flexcoders] Beginner "Event" Question
I created a custom event to pass a string with, shown here:
package events
{
import flash.events.Event;
public class ConfigFileEvent extends Event
{
public var configFile:String;
public function ConfigFileEvent(type:String, configFile:String)
{
super(type);
this.configFile = configFile;
}
override public function clone():Event {
return new ConfigFileEvent(type, configFile);
}
}
}
I then have in my main class an event metadata tag, a dispatch and event
listener shown here:
http://www.adobe.com/2006/mxml";
creationComplete="initApp()" >
[Event(name="ConfigFileEvent", type="event.ConfigFileEvent")]
However Flex builder won't compile because of the error:
Access of possibly undefined property CONFIG_FILE_EVENT through a reference
with static type Class. in the addEventListener line. Can someone provide a
better insight as to this error and what it is that I am doing wrong?

[flexcoders] Someone have sometime to help me develop a datagrid before this weekend? Key word is help me - not write for me.
Anyone, Wwas wondering if I could ask a couple of questions - aside from this one. 1. Is it possible to 'solely' in actionscript make a datagrid from an arraycollection? I am trying and it keeps dying. 2. Is it possible to have the cells in a datagrid show one of three png images all changing on the fly as the data changes? I figure if I build the grid correctly in AS then when I update the dataprovider it will update the grid in real time. 3. Is it possible to put a different tooltip on each cell in the datagrid? - so I can say show the IP address as seen below in the arraycollection but not in the grid itself. 4. Would you have the time and/interest in helping me forge my way through this? I don't want you to write it all - I just want someone to help me think my way through it before this weekend. I want to write it myself - i.e. learn but need someone available to point me toward my mistakes and help me through it via code suggestion and or known tutorials. Sample of my what I am dealing with private var _columnHeaderArray:Array = ["3750", "Serimux", "Novatel", "4033", "4039"]; private var _aliveDeadArrayCollection:ArrayCollection; Then when the httpservice call returns my xml file I do this: _aliveDeadArrayCollection = result as ArrayCollection; My mxml from before was like this - -r
[flexcoders] Linux says corrupt file when clicking on an air app.
Question for anyone who can point to a better answer than what google has currently provided: We wrote a adobe air app on OSX using the latest version of flex builder (3 series) and the latest adobe air sdk. When we export the air app and double click it on windows or OSX it installs fine and runs. When we try the same on Linux we get an error message saying the file is corrupt and we need to contact ourselves (developers) for another copy. I have tried this as root and general user on the linux system. Any pointers is appreciated. -Ray
[flexcoders] How do I create in ActionScript what MXML lets me do?
Data can be found at http://www.silenttrace.com/deviceData.xml Question one - How can I create my list, "onList" in pure actionscript vice mxml? The reason I want to do this is because I get a null exception otherwise. I imagine its because I am instantiating the itemrenderer before I have any data in my arraycollection since a http service call needs to get the data. So I thought if I wait till line 35 and then instantiate the list in pure actionscript I am golden. Can someone let me know if that is possible or how I could achieve this? Things like setting itemChangeEffect and such seem to be only in mxml. Question two ignore the itemRenderer of "onList" and you will see that I get an error ever time I select the zero Item in the list on the left and click the addToOffBtn. here is main code http://www.adobe.com/2006/mxml"; layout="absolute" creationComplete="init()" width="800" height="600"> http://www.silenttrace.com/deviceData.xml"; result="getDeviceDataRequest(event)"/> Here is itemRenderer http://www.adobe.com/2006/mxml"; width="100%" height="65" cornerRadius="10" borderStyle="solid" backgroundAlpha=".3" backgroundColor="#00">
[flexcoders] Updating WITHOUT human intervention
Say your school has a remote system collecting data miles away and you need to update it with no one there to help click through the dialog. Is there a way to do an update in adobe air without human intervention? Meaning we post a new update on the server and the next time the remote app comes online it sees the new update and self updates without a human clicking a button. A small tutorial, blog pointer or even small sample idea would be helpful. Every time I try it on my own I seem to be missing something. -ray
[flexcoders] Question about ArrayCollections
Here is some code of what I am using today:
private function startAliveDeadCheck():void {
startMonitor("127.0.0.1", 80);
}
private function startMonitor(location:String, port:uint):void {
monitor = new SocketMonitor(location, port);
monitor.addEventListener(StatusEvent.STATUS, checkStatus);
monitor.pollInterval = 1000; // every second
monitor.start();
}
private function checkStatus(e:StatusEvent):void {
if (monitor.available) {
connectFlag.text = "ONLINE";
} else {
connectFlag.text = "OFFLINE";
}
}
The code works fine if you are monitoring one and only one socket. I wanted
to modify the code to handle a bindable arraycollection but can never seem to
pull the data out. I try changing the first function to use this:
[Bindable] private var socketsToMonitor:ArrayCollection = new ArrayCollection([
{ip:"127.0.0.1", port:80, aliveOrDead:false, monitor:},
{ip:"127.0.0.1", port:8080, aliveOrDead:false, monitor:}
]);
everything is fine. but I hit errors when trying to pull out each array and
starting a monitor on it. I tried
for each (item in socketsToMonitor) {
trace(it...@ip);
}
I get an [Object object] and not the IP address. Any idea's of where I am
going wrong. Once I even achieve this I am assuming my attempt to monitor
function will need to be redone. I welcome any pointers and thanks for the
help.
-ray
