Flex :: Interface - Getting Value Of The Object Attribute
Dec 1, 2009
i have an xml which contains 'interface' sub tag, iam converting xml to object using SampleXmlDecoder. compiler did not allow me to access the value of the 'inteface' attrible of the resultobject.
[Code]....
its treating interface as keyword. the solution for this.
Suppose I have a list of objects of a certain custom type and I need to find an object given only the value of one of its attributes, how do I do it?
Eg.
// Where user1 ... usern are objects of some class User users = [ user1, user2, user3 ... usern ] // How do I find out the objects that have the "foo" attribute set to "bar"
This object is ok, and shows up correctly in debug mode. The problem is I have a country name i.e. private var _country:String = "Angola";, and I want to get the corresponding value 'AO' from the XML object. Do you know how to do this?
I have tried loads of Livedocs examples, but cant get it to work. P.S. I am working on a HtpService & WebService driven app to display global weather conditions overlayed on a Google Maps interface. Going to make it available to the Flex community when finished.
If I execute the code below in FlashBuilder, I get the following error (I translate it) TypeError: Error #1009: Access to an Attribute or Method of an null-Object is not possible. at components::NumDisplay()[srccomponentsNumDisplay.mxml:39] This line in NumDisplay.mxml is the problem:
I found at this Adobe tutorial a nice "RemoteService" class that creates a RemoteObject and contains the functions for handling the result and fault events. If I wanted to use this approach, how could I pass the data from the result handler to interfaces that modules from the main application could use?
I could put the RemoteService/RemoteObject in the modules, but (in my opinion- and I could be wrong) the best design seems to be using the remote calls in the main app and passing the data along to the modules.
How to give a ms word like interface to a user so that he can enlarge and contract the display objects like Images, canvas, Hrules etc. at runtime in an web application?
Recently I got trouble with totalFrames attribute of MovieClip object, this is the case: in Flash CS, I created two movieclips, one has say 10 frames animation, another one, I drag the first MC in to it, then the second MC has only one frame in it's own time line, right? Then I export them as SWC file to include them in my project. Here's the problem, when I'm trying to get total frame number of these to MC like below, I just get to actual number of frames in the second MC:
[Code]...
So my question is, is there any way to get the actual number of frame for those MovieClip resource like the second one, without visiting any sub-movieclips in it
Is there a way i can Loop through the attributes of a strongly typed Object or just convert a strongly typed Object into a generic Object.I tried typecasting a Strongly typed object created using LCDS into a Object.But it just returned me a typed Object.
i'm working on a gallery that loads thumbnails from an xml file into 3 columns and when you click on a thumbnail it opens a new window with the fullsized image in.
I have modified code from a gallery tutorial to load the thumbnails from a xml file. They are going in 3 columns at the moment (I don't understand why but they are) but only the last image has a hand cursor when you rollover it, and then when you click on it, it traces "undefined" into the output box.
I have put
Code:
trace(images_arr[i].attributes.fullsize);
just below the bit where it loads the thumbnails and it traces the right path from the xml file for each image.
get it to trace the right path from the xml file when you click on ALL the thumbnails, not just the last one.
Code: function GenerateThumbs() { images_arr = images_xml.firstChild.childNodes; gap = 10;
I have a flex 3 project with a root mx:Application. The width and the height are set to pct values, because the application has several sizes that can be chosen by the user, so the correct size is set on the embed's width attribute.
how to access the value in that attribute. I read in several places that this.root.loaderInfo.width should give me that value, but it always returns 500, which I am guessing comes from the default application container width [URL].
I realize I could pass it as a flashvar, but that is not a good solution in this case due to the nature of the project. I've also tried pplication.application.width, stage.width, and stage.stageWidth, to name a few. I can't depend on any of those values, since they change based on the browser zoom level.
I am currently just finishing a project and I am having a big time problem with an ExternalInterface call. My application runs fine but when the javascript call is being made from flash using external interface, IE is going from the "Done" message, to showing the "!" icon, with "error on page" as the message. There is no error that is showing up in Firefox.
The current error I am seeing is an 'Unterminated String Constant', which wouldn't be a problem except for that it appears on line 1... which is [URL]
i was wondering how you guys set up different projects that share an interface (interface object, not an UI element). i have several modules in separate projects that use an interface from the main project. right now i'm either doing it by copying and pasting the interface to the module projects or by adding the source path to the project.
I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):
I am having trouble parsing some xml that has a few attribute names with : characters in them. The compiler is not throwing any errors and when I trace my complete xml object out it is all there, however when I try to trace out any element or node it keeps comming up undefined. I removed the attribute names with : characters in them and everything works fine. I cant seem to target the attributes either to delete them.
I am able to get <styling> as a XML but I cannot figure out how to parse the style object in order get the color, fontFamily fontSize attribute values. I am also unable to access the lang attribute value <tt xml:lang="en">
I'm running into difficulty passing a strongly typed object, AttractView, to another method, addView() which expects an IWizardView interface that AttractView does implement. When I pass it as-is (as shown below), I get the compile error CaptureApplication.as, Line 120 1067: Implicit coercion of a value of type AttractView to an unrelated type IWizardView. Casting to either IWizardView or BaseView before passing yields a similar error at run time.
I have this variable in Model class:[code]I've used BindingUtils to get notified when the XML changes:[code]Function onChange gets triggered when I assign an XML to the variable, but not when I change some attribute of the XML: Model.getInstance().someXml.@attr = "newValue";
I have two variables. One variable will contain the game type, either Squash or Table Tennis. The other will contain one of the following strings "TIME1", "TIME2" or "TIME3". The variables are called game and time. I have tried many variations on the code below to get the needed attribute but with no joy.
var result:String = node.sport.(@GAME == game).(attribute(time));
I'm using a CSS file to style my flex application. can I use components IDs to change their style from the CSS file? Or I should add the styleName attribute for each element?
I'm trying to create a button skin, where i can set fillColors like in a Flex 3 button, using CSS. It was easy to set the color of the gradients, by reading them from the CSS: adding a few lines in updateDisplayList: fillGradient1.color = fillColors[0]; ...
How can i set the colors for the other states, from script? I tried adding fillGradient1.color.down = fillColors[2] and it's not working...
have an RSS feed, within Flex I have connected to the feed via HTTPService, the XML structure is as follows (not exact, but for the purpose of the question). I am able to walk down the xml and access the data within the title and link nodes with success but when I get the the description node and try to access the img and src attributes within it, I haven't had any success. Reading about parsing with e4x the example I get is:
var xList:XMLList = xData.channel.item.description.(attribute("src")); or var xList:XMLList = xData.channel.item.description.(@src);
What is the best method to test the existence of an attribute on an XML object in ActionScript 3 ttp://martijnvanbeek.net/weblog/40/testing_the_existance_of_an_attribute_in_xml_with_as3.html is suggesting to test using
if ( node.@test != node.@nonexistingattribute )
and I saw comments suggesting to use:
if ( node.hasOwnProperty('@test')) { // attribute qtest exists }
But in both case, tests are case sensitiveFrom the XML Specs : "XML processors should match character encoding names in a case-insensitive way" so I presume attribute name should also be match using a case-insensitive comparison.
