[flexcoders] Unable to do matrix transform to flip an image - it vanishes
Hi y'all, I am trying to do a horizontal flip transformation of a png image as follows: var flipMat:Matrix = img.transform.matrix; flipMat.scale(-1, 0); flipMat.translate(img.width, 0); img.transform.matrix = flipMat; The idea is to scale by -1 and then move it to the right by the width. I end up losing the image however. If I put a box around the image, it goes blank, if I remove the box and just have the image, it is nowhere to be seen. The image is an PNG and is loaded at the upper left corner of the enveloping HBox. Any ideas what is going wrong here?
Re: [flexcoders] Unable to do matrix transform to flip an image - it vanishes
Hi, scale() method takes multipliers as arguments, so 0 as y factor will set height to 0. You should use scale(-1,1). thomas --- http://www.web-attitude.fr/ msn : thomas.parqu...@web-attitude.fr softphone : sip:webattit...@ekiga.net sip%3awebattit...@ekiga.net téléphone portable : +33601 822 056 2009/7/24 jomorano06 jo.moran...@gmail.com Hi y'all, I am trying to do a horizontal flip transformation of a png image as follows: var flipMat:Matrix = img.transform.matrix; flipMat.scale(-1, 0); flipMat.translate(img.width, 0); img.transform.matrix = flipMat; The idea is to scale by -1 and then move it to the right by the width.

[flexcoders] Can not select itemrenderer

Any advice would be much appreciated.

this renderer.

[flexcoders] Re: QTP automation problem of custom component
Andriy, Thanks for the help...though I was pretty sure I had it configured as you described. So I uninstalled and followed your steps again just be sure...but I get the same behavior. QTP IS able to see the FlexRandomWalk component but it cannot see its children, even though numAutomationChildren, etc. are implemented and reporting the correct number of children.

The component implements UIComponent directly and contains children. I followed the instructions and wrote a delegate implementation for the component and a matching TEAFlex...xml class definition file. Am using a simple wrapper index.html file. The project was updated with the -include_libraries to pull in the automation swc's and a -includes to pull in my delegate implementation. In QTP using Object Spy it sees the FlexCalendar along with the events and properties I exposed in the class definition file. PROBLEM: QTP can not see any of the child items even though the numAutomationChildren and getAutomationChildAt are implemented. The value of numAutomationChildren on the FlexCalendar instance as reported by Object Spy is correct...but they just show up as BrowserPageWinObject. Any ideas what I'm doing wrong? The crazy thing is, I downloaded the RandomWalk sample/example and it behaves for me in exactly the same way...numAutomationChildren indicates the correct number of children but they are not identified correctly by Object Spy. So perhaps I am building it wrong - even though QTP does see the custom component fine. Is there some special significance to the randomWalkClasses src folder or could these files have been included at the same level as the RandomWalk.as class itself? Tried with Flex Builder 3 with SDK3.2 and testing under IE7+QTP9.5 and IE8+QTP10 - same behavior. Note: Same swf works fine with RIATest albeit with runtime approach directly on the swf, i.e. all child components are identifiable.

Re: [flexcoders] Re: FileReference Upload
Hi Tracy, Perhaps i mis-spoke what i mean is..the file does the upload without any problems...but when i try to write the file to a directory it fails... here's the scenario: I have 3 separate servers. the first i run web-applications from. the second is simply storage. and the third runs flash media server... I'm trying to upload files to the storage server so that fms can stream those files... the server running the web-applications has a link to the storage server and that link appears as if it's just another directory on the web-app server's file system...and since my web-app is running as me..it has full write permissions... the reason i believe it to be a flex issue is: 1) even though it's usually with regards to authentication...it appears there are serious issues with regards to Flex, Firefox and session cookies...and since my initial problem involved my upload not working in firefox(any Mozilla based browser) and working in IE i know there is some correlation there. 2)by sending some variables in the URLRequest data property i can break it in either browser. 3)if i hit my upload button a second time...it mysteriously *does* write the file to the storage server... so..this has to be an issue with flex... thanks for clarifying.. percy On Fri, Jul 24, 2009 at 12:18 PM, Tracy Spratt tr...@nts3rd.com wrote: Wouldn’t this be a ruby on rails issue rather than a Flex issue?

Re: [flexcoders] Flex Architecture Question
I think you may be a bit confused. Flex won't talk directly to a Java server application without something like BlazeDS in the backend (or by making http requests). Its a different model to Struts which generates your view directly, and handles the response from it automatically. Session handling can be done in the normal way except you have to realise that any data that changes on the server has to be sent to the flex app. Any data thats on the client has to be sent to the Java app. For your question about EJB from flex again look at BlazeDS. Try taking a look at the sample applications. Regards, Wesley Acheson On Thu, Jul 23, 2009 at 8:23 PM, guess what myworld10...@yahoo.com wrote: I am struggling to get the Best Architecture.

Re: [flexcoders] Re: FileReference Upload
If the file is uploaded and the data is sent. Then its something on the application servers side. It sounds like you require a session to write something to the webserver and you don't get a session untill the first time the request hits. To verify this. Browse to the second storeage website. This will probably write a session cookie. Go back to your flex application and then try the test thats failing. If it works then its something server side thats requiring a session.

RE: [flexcoders] Re: Question about a flex component
No, I don't have an example and don't have time to create one for you since I'm a development engineer, not a support engineer. But here is what you should try, learning as you go: 1. Create an app with an mx:HorizontalList. 2. Make it show data items by assigning its dataProvider. Put in more data items that will fit. 3. Turn off its scrollbar by setting horizontalScrollPolicy=off. 4. Create mx:Buttons for Previous and Next, positioned to the left and right of the HorizontalList. 5. In their 'click' handlers, put code like horizontalList.horizontalScrollPosition += 1. Use -= for the Previous button.

When you click it again you'd see 20-29. So you'd need another icon (previous page instead of next page) to go back to 10-19 and then 0-9.

Re: [flexcoders] Re: FileReference Upload
HI Percy, Having never used rails I can't tell you how it works. What I can tell you is that usually (well over 95%) of the time passing a session key from one server to another is useless as the server won't have access to the information in the other servers session. This means that you have just passed a meaningless string. (note the remaining 5% of the time is when there are distributed sessions pointing to a common database but thats not going to be the case on different domains) You need your rails app to take uploads without any session or you need to generate a session(say by requesting an image or something else) off the application before hand. I wouldn't have imagined that it should fail like that but I don't know about rails. It just appeared the symptoms seems suggest that this must be the problem. I suggest asking a rails mailing list in this case :( You may get lucky and find people here who know about it. Oh as a suggestion why not have server 1 push its content to server 2? That should be easy enough to find information on.

Re: [flexcoders] Flex Architecture Question
So does AMF; it's just transferring binary data instead of ASCII data. The reason you need a server side piece is to translate that binary data into something usable by the application server. I will admit, I responded to your e-mail without reading the original question; though. So, if I was out of line I apologize. Wesley Acheson wrote: Yes I know.

RE: [flexcoders] Sideways text
If you use an embedded font I think you can rotate Flex 3 text components. But if you want to use a device font, you would have to develop custom components that use FTE or TLF instead of TextField to render their text, and you'd have to require Flash Player 10. Looking at how Flex 4 implements its new text components would probably be useful if you're going to do this.

RE: [flexcoders] Re: Question about a flex component
You add child components which are UIComponents to a container like HBox.
But you add data items to a list-based control like HorizontalList. These data
items then get displayed by item renderers, which are children which get
automatically created to display data items. The children are managed by the
list, not by you... you manage the data, not the renderers.
By default, data items are expected to have a 'label' property to display,
unless you set the labelField or labelFunction of the list component. They can
be plain Objects, or instances of data classes, or anything else, but
typically they aren't visual components.
Here's an example of adding two data items to a list using ActionScript.
myList.dataProvider = new ArrayCollection();
var item:Object;
item = { label: One, data: 1 };
myList.dataProvider.addItem(item);
item = { label: Two, data: 2 };
myList.dataProvider.addItem(item);
