[flexcoders] pieChart (callout) labels not redrawn on drill down
Hi, I'm having a pieChart double click enabled, to get a drill down for the selected pieChart item. This drill down is displayed aside of the original chart. The problem is, that the labels for the original chart disappear (or do not get redrawn) when the original chart gets double clicked the FIRST TIME. If you double click (whatever pieChart item) again, the labels appear. Does anybody have an idea why this happens ? thanks _rico
[flexcoders] PopUpButton as ItemEditor for DataGrid
I'm pushing the envelope in terms of how many editable fields are going to fit within the available horizontal space. The issue is basically how to open an itemeditor that is not constrained by the width of the column. So I've been investigating having a text field popup when in editmode that gives the user more space to edit, that will not be constrained by the column width. I've tried using a PopUpButton as the itemEditor and having the text field in there, but what I'm seeing is that if you doubleclick on the cell too quickly, an exception is thrown in PopUpButton.as - it appears that the _popUp isn't yet defined. If you click more slowly, there's no issue. I'm not that happy with the PopUpButton solution as the first thing the user sees is the button and has to click again to open. What I'd prefer is simply to have the itemEditor popup on its own without further user interaction. Ironcially, I've got a another column working perfectly when editing a list of items. But for some reason, my TextField editor popup is buggy and I haven't been able to identify exactly why.

RE: [flexcoders] Could the Flex Gurus shed some light on this behavior?
Mike, From a performance point of view - you wouldn't want to be loading external assets twice. It's good that you see this: load what you need. need what you load. load it once. use it many times. What will help is to think more about where that data ends up. accessing the raw data is always nice - but in Flex you have all the visual data you need right in front of your eyes (BitmapData). Once you've loaded your map use BitmapData (with matrix) to push maga-map pixels to your mini-map. This will give you ultimate control of sizing, key-holing, panning, etc. Rick Winscot From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Mike Anderson Sent: Wednesday, April 23, 2008 1:07 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Could the Flex Gurus shed some light on this behavior? Hello All, For the longest time, I've been wondering why 2 Loader Controls, are unable to share the same content. Then again this may be by design, and my lack of knowledge relating to Flex could be why I don't understand this. For example, I have a SWFLoader Control which comprises the majority of my Application's desktop. It displays a loaded Map, in which users can drag icons onto the desktop, pan, zoom, as well as many other functions. I have a small navigator window that stays on top in a static position, in which the same content displayed in the SWFLoader, also gets displayed in the Navigator Control. The Navigator Control just gives the user an indication of the Map portion being displayed in the main window. In order to avoid having to load the SWF File TWICE, I thought I could set the content property of the Navigator Control, to the SWFLoader.contentLoaderInfo.content property - but when I do this, the loaded SWF disappears from the main screen, and appears in the small Navigator Window. Is this literally how things work in Flex? 2 data aware components can share the same ArrayCollection for their dataProvider Property, but 2 graphical display components, cannot share the same content? I would be grateful to hear the experts explanation on how this type of thing works within Flex. Thanks in advance for all your incredible help, Mike image001.jpgimage002.jpg

In that case, since each DataGrid already has a 'dataProvider' property, it wouldn't be necessary to override this unless the 'dataProvider' takes some weird form that DataGrid doesn't already understand. However, this isn't as good an approach, because the DataGrids won't get created until you add the MultiDataGrid to the display list, so you couldn't write code like var mdg:MultiDataGrid = new MultiDataGrid(); mdg.getUpperDataGridAt(3).dataProvider = ...; 3.

[flexcoders] Re: Flex decoding soap complex objects in complex objects
If you have control of the web service itself and no one is forcing you to use SOAP you have other less complex, better performing options. 1) If you want to use XML, try using REST style web services or a straight XML representation of your object and you can explicitly control how you read/write the object(s), 2) If you have some Ajax code that might call it also, you might consider using JSON, 3) But the best solution if your client is Flex and will most likely always be Flex (in my opinion) is to use AMF. I know that Flex supports SOAP web services but after working for a while with fairly complex SOAP web services using Java tools but having to play well with .NET generated solutions convinced me that complexity for the sake of complexity (SOAP) is going to make your life harder no matter what tools you use. But I understand if you have some 'architect' or manager telling you that you MUST use SOAP.

So the problem: Keeping the AdvancedDataGrid nodes that were already
expanded, open after a filter and refresh (specifically
a 'GroupCollection' refresh).
First, I got a nice array of objects containing the 'nodes' for the
grid nodes that were opened, adg.dataProvider.openNodes
Next, I did the filter and gc.refresh().
The final step was to iterate through all the nodes, find out which
ones had the same GroupLabel, and expand them
using adg.dataProvider.openNode(node:Object).
This is where I ran into problems. When I tried to re-open a node
using openNode, the node would expand, but the nodes below it would
not be in the right tree level (it seems as if they were stepping
down in level one by one, even though they were supposed to be all on
the same level below it). Now here is a real kicker! If I go to
click on anything in the grid after that, the display automatically
corrects itself! So odd.
If anyone has seen the same thing, or know what I'm even talking

[flexcoders] newbie design question
I have been working in Flex for about 3 months now. I am writing a geometry tool that allows user to create points, line segments, circle and polygons, as well as constraints between these objects (e.g., distance, angle, perpendicular, etc.). Initially, I created a (subclass of) ApplicationControlBar and (a subclass) of Canvas. Tools in the app control bar and objects (by which I mean geometric shapes) in the canvas. My canvas listeners for Event.RENDER and then, provided it's been told that something has changed, calls its draw() method - which, essentially, loops through objects, drawing them to the graphics object - after having cleared the graphics object. Similarly, the canvas listeners for various MouseEvents and KeyboardEvents, and traverses the list of objects doing hit tests. This was okay until I needed to render text (for distances and angles). Apparently there are ways around that - by rendering text to a bitmap and adding bitmap to graphics command stack (though I have yet to actually get this working). There are other concerns that I have about my approach thus far. But switching over to a model where each geometric object is a Sprite or a Shape raises some questions, too. Currently, I can highlight points, edges and angles of polygons are the mouse moves over them. I have no idea how I would accomplish this with Sprite or Shape, as neither appears to have a draw() or paint() method... Would I need to add Shapes for selected look for each point, line segment, etc. and toggle visible property appropriately? Is this something that skins might be used for? If so, how? I realize that this is a somewhat open-ended question, and I am hesitant asking it. I have done a fair amount of reading (books, blogs, docs), but I think that I am missing something here. If you have pointers or advice, I would be most grateful. Thanks. -Eric

[flexcoders] history manager and deep linking
I am a bit confused on history manager and deep linking. If I am using deep linking in my application I know that historyManagementEnabled will be set to false at the application level. However, will I still be able to have my custom components implement mx.managers.IHistoryManagerClient and manually register the component with the HistoryManager? Will that break deep linking?
[flexcoders] How to check if components have been created yet when creation policy is auto
Hi, I am trying to checking if children of a viewstack have been created when the viewstack's creation policy is set to auto (as per default). I am getting a null pointer reference when trying to access a value on a component nested in a viewstasck. I would assume i need to check if the children have been made first and if not call myViewStack.createComponentsFromDescriptors(true); Does anyone know the way to check this? Many Thanks Luke
[flexcoders] Collapsible controls
It seems to me that it's pretty common to need some UI that is modeless (i.e. not in a pop-up) but easy to get out of the way to save real estate. I've seen the FlexStore (haven't studied the code in a while) , the WindowShade in flexlib, and examples of programmatically dividing a DividedBox. I like the latter, because when the collapsible UI is expanded, the ability to resize is still valuable. Is it possible to skin or otherwise customize the HDividedBox so that additional buttons could be placed with the thumb? Any other approaches that have worked well for any of you?

I need to pass a parameter to a function using actionscript.
However by default, all you can

this is easy to do in MXML,
but can it be done in actionscript? The documentation has this to
say about it:
Because the second parameter of addEventListener() is a function,
you cannot specify
parameters of that function in the addEventListener() call. So, to
pass additional parameters
to the listener function, you must define them in the listener
function and then call the final
method with those parameters.
But what does it mean to call the final method with those
parameters. No examples are
given. Could someone give me a quick example of how this is done?

One work around is to just use action script to swap the image with an

then reswap again with your new/same image so that you now have forced
flex to repaint it.
does that make sense?

HorizontalList requires that all items be the same width and height. At

If you're subclassing, you can set itemsNeedMeasurement=true and call

RE: [flexcoders] Using 100% width on canvas? getting scrollbars?

get the node index of the XML node that is being represented.
private function myMouseDownListener(e:event):void{
//assume for simplicity we know what was clicked
//is always going to be a direct child of the renderer
var parent:* = e.target.parent;
var d:XML = parent.data;

Depending on what you are trying to do, you can usually extrapolate
from the target of the event to what you need to know using the
parent or the owner chain.

RE: [flexcoders] AIR HTML component - html tag / text selection
I was casting around for that some weeks ago, I think the closest I got was overriding the onclick function in actionscript. Of course that gets called for *any* click, but crucially the select ones will be in there, and give you a reference to the element selected, from which you can at least get innerhtml or outerhtml properties.

I haven't looked at your code yet. It's a busy week for me so I'll wait to hear if you still need me to dig through it. Naturally, I wouldn't have spent all this time on this if I didn't want to do it right, so ultimately I would like to get to the bottom of it. But for now it is patched to work acceptably, so if you don't have time, you don't have time. Thanks; Amy

[flexcoders] Re: Possible bug with Shape (or DisplayObject) when increasing the width (or scaleX)
Just to make it short. Why when I change the width of a DisplayObject ( Shape) it changes its X coordinate ?

[flexcoders] Copying an Object
I'm sort of a newbie to Flex/ActionScript...can someone tell me the best way to copy an object to a new variable? For example, I have a variable named obj1, datatyped as Object. Let's say that I've set obj1.property1 = foo and obj1.property2 = bar. Now I declare a variable named obj2, datatyped as Object. I tried: obj2 = obj1, but when I evaluate the variables at run time, obj2 evaluates to null. Do I have to explicitly copy each property from obj1 to obj2, or is there a better/easier way to do this? Hope that made sense.
[flexcoders] Strategies for Long Text and Images
Greetings - I've been building a site that has long pages of text with lots of illustrative images. Dealing with text and images in an editorial layout fashion has been surprisingly cumbersome in Flex (especially given how easy it is to build elegant, stateful apps, and hence I'm wondering if I'm missing something. Thought I'd run my approach by folks her for a quick sanity check. Here's what I need to achieve: - Pages with 12 - 20 long paragraphs of text - Most paragraphss preceded by a subhead of different font face/size color - Lots of interspersed images aligned left, center, and right with wrapping text (for left/right) - Inline text links - Embedded fonts - Flexible (stretchy) design For reference see the site in progress at: http://djethan.com/westwind/ . Click on Martial Arts then on History. Dismiss a coverflow error if you see it. My plan had been to achieve this by having all the content be in TextAreas (set to editable and selectable = false) and then handling the subheads, images, and links using htmlText and the supported html tags. Two things made this impractical: 1. No way to center an image in htmlText! The IMG tag does not support center as a value of the align property; wrapping an IMG in a P with ALIGN=center also fails as does setting the horizontalAlign of the TextArea (with all other text wrapped in P with align=left). 2. The supported html tags to not take a class attribute, nor do they respond to element selectors ie you can't use CSS to style them =( These things being deal breakers I've fallen back on this approach: VBox Label styleName=subhead/ Text styleName=body htmlText blah, blah, blah IMG align=right blah, blah, blah IMG align=left /htmlText /Text Label styleName=subhead/ Text styleName=body htmlText blah, blah, blah /htmlText /Text Canvas IMAGE horizontalCenter=0/ /CANVAS Label styleName=subhead/ Text styleName=body htmlText blah, blah, blah /htmlText /Text /VBox It's working but, seems heavy handed and slw - page loads have a noticeable lag. Am I missing anything, better ways to do this? thanks, ethan

RE: [flexcoders] Button in DatGrid problem
The simplest solution is to use an HBox, with horizontalAlign=center,
then put the button inside that.
But using containers in renderers can cause performance problems if you
have many renderers. See Alex's blog for examples on how to write
lightweight renders.

[flexcoders] Re: Programmatic scrolling of a TileList?
It sounds like you are on the right path, however, initially the scrollToIndex() is 1, correct? Each button click should increment the scrollToIndex() by 1 (or -1 if moving left on the list), so instead of scrollToIndex() being 4 after the click, it should be 2. Next click, 3, etc Just be careful to account for the total number in the index so you don't get an error by trying to go to index position of negative 1 or, in this example, 5. --- In flexcoders@yahoogroups.com, djbrown_rotonews [EMAIL PROTECTED] wrote: any help out there? --- In flexcoders@yahoogroups.com, djbrown_rotonews djbrown_rotonews@ wrote: anyone? :) --- In flexcoders@yahoogroups.com, djbrown_rotonews djbrown_rotonews@ wrote: I've got a tile list component that I want to be able to scroll through horizontally without the visual presence of the scroll bars themselves.

Re: [flexcoders] Re: Copying an Object
As an additional note, when using ObjectUtil.copy() with your own
user-defined classes (i.e., not Object, ObjectProxy,...), you may have
to use [RemoteClass] metadata or the registerClassAlias() method.
The problem is that ...when an object is deserialized from AMF, it
does not automatically get created as a class instance. The object
might have all of the properties of a class instance, but it will not
be a true class instance unless the AMF packet includes type
information about the object. The type information gets added to AMF
in one of two ways:
- Using the {RemoteClass] metadata tag.
- Using the registerClassAlias() method.
...
I found this out the hard way.

[flexcoders] Relating series and axes
I'm a little unclear how one associates multiple series to the same axis, when there are multiple axes present. With secondVerticalAxis (or whatever it was called) deprecated, it appears that the axis definitions must go inside a series definition. But now I want yet another series to refer to the same axis. Do I just put the axis under an arbitrary series, and then refer to it by id in the other series, or do I define an axis for each series, but only reference a subset of them in the mx:verticalAxisRenderers tag? Thanks!
