I'm trying to make an existing FLEX application section-508-compliant, by getting it to work smoothly with the JAWS screen reader. It kinda sorta works, but one immediate problem is that when you first go to the login screen, your cursor ends up in the userid field, but JAWS doesn't read anything useful (like the label of the field you're in!) until you hit TAB or something. Is there a way to force it to speak immediately on application startup, without making the user tab/backtab just to hear where they are?
For that matter, as cool as it is that it reads interactive controls as the user tabs around, sometimes you just need to make JAWS say something at a particular point in the logic, which might or might not be associated with a conrol... as if you could write AS code like "jaws.speak('');".
Flex application is being made accessibility compliant. When a custom component is made visible based on some condition, the first item (either text or formitem or textarea) inside the component is skipped by Jaws. It reads from the second item. On pressing UP arrow, the first item is then read. Is there a way to make the first item accessible without need for pressing UP arrow?
I was wondering if there is a limit to how much Jaws (screen reader) can read in a text area in Flash. my text area contains about 15 lines, and always it stops reading at a certain point. In one test I was deleting one word, and then Jaws read one more for me(since I guess I deleted one). So it looks like there is a limit on how much it can read through AccessibiltyDescription property . How I can make the Jaws to read the whole content in the text area? I am working with flashbuilder and SDK 4.1.
But this did not give me the binary content of the file.. how to retrieve the full binary content of the given file using Flex (I am using FP 10.0).....
I am creating some application in flex and one of my purposes is to read content of file and display it in flex. There is huge problem, when I have file written in polish (which contains some special characters) because amfphp transfers this contents few seconds, which is to long (reading and sending content of file without any polish character if fast).My php code reads any files fast, so problem is on amfphp side. Is there any solution or I have to go with HTTPService and load contents of file directly from flex?
I'm going to implement a file uploading application using flex 3.5 and php. In the flex code I need to read the content of the uploaded file without calling the FileReference.load() method (Since it is a big issue when uploading large files). I checked many online articles and didn't find a way to do this in flex.access the content of this file without using FileReference.load() method?
I have what seems a straighfoward situation: I update the source property of an image, when the image is loaded i want to redraw the border skin to fit the new size of the image.
newImgEdit.addEventListener(Event.COMPLETE, loadImgComplete); newImgEdit.source = myurl_ressource; private function loadImgComplete(evt:Event):void {
I have a component and I add some content to it making it change it's size, immediately I need it's new size, but flex only updates the size in the next frame by calling updateDisplayList. how can I force it to update the size of the component right away.
I have an mxml pie chart, which I would like to rotate slowly prior to a button click, however on click it needs to stop immediately (or at least reasonably quickly) and then the callout labels are introduced with a fade.
I have experiemented with both a timer function to achieve this:
In flex when I allow user to download a file using :
dwFile = new FileReference(); dwFile.download(downloadURL, dwFileName);
Is there a way to ensure that the downloaded file always ends up with the extension .tar or any other extension for that matter? By default I give it a name like xyz.tar, but as of now the user can tamper with filename, including its extension. Can I prevent him from doing so?
I'm trying to create a class that contains an array. However i want to require that the items in the array are themselves of a specific class. Im told there is some sort of tag you can add to do this, but for the life of me i cannot find what it is.What i hope for is something like:
public class myClass{ public var foo:String; [ArrayType(class="BarClass")]
I need to be able to start/stop or reload this swf with purely javascript as I don't have access to the source swf file to add any actionscript.I figured the easiest way to pull this off is by removing the element and replacing it forcing a redraw with would hince reload the swf movie. Though ie seams to cache the flash element and pretty much look over any updates I make to the embed/object tags and keeps right on going.So how do I force IE to redraw/update a flash element on a page?
I have an AdvancedDataGrid. One of the columns in the grid displayed with help of custom render. During the application run, I set another custom render to the same column.When I scroll data in the grid (change values for the custom renders) they display new view correctly.I want that they dispaly new view automatically (when I set them): so I think I have to call them and tell tham to refresh rgeir views.
I've got a small action-script chart, that's meant to be live updating, and also be able to support more than 10000 points of data. The way it's currently set up it doesn't need to redraw the whole chart if the new line we wish to add doesn't extend that chart's boundaries. Yet it does, the redraw regions show the whole chart as being redrawn as opposed to the single line i need to add. When the chart gets a new piece of data from the javascript it does the following.(some stuff has been stripped for clarity.[code] Is there any better way to do that, that won't redraw the whole screen? Is my coding pattern wrong for this type of update?
Is there a simple way to force all the child components of a Flex app to redraw when that app is resized?
For instance, I have a HDividedBox with percentHeight and percentWidth set to 100. On the left hand side of the divided box is a data grid and on the right side is a number of text inputs. The divided box is not added to the view stack until after the user logs on.
If I resize the app before the HDividedBox is added then the box takes up the full size of the app, whatever that may be. However if i resize the app after the box appears then the box retains the same dimensions it does when it was first added.
I would have expected that on the resize of the app then all the children would redraw (the application component itself appears to).
I have a ProgressBar in MANUAL mode responding an URLLoader's progress events that seems to get drawn far less frequently than I would like. If I debug the app, I can see many events firing from the URLLoader yet it seems that the ProgressBar is being re-drawn at some random and slow rate.
Now if this was my own code (URLLoader is a black box), I would pause once in a while to let the UI update, say via loop with a timer. I presume that the URLLoader itself is blocking the main thread from processing drawing code. Adding validateNow() and invalidateDisplayList() does not seem to help much.
Now there are many TResources (just a class that can manage its data) being loaded in sequence, but the URLLoader is so greedy that it does not let the UI get updated more than a few times when loading & processing (parsing into XML objects) 50 or so 10KB files. So just counting which files loaded visually does not work either; I'm lucky to get 2-3 screen updates the entire time.
Loading a 700MB file looks much better, but again the progress bar updates are random and slow.
Additionally, I'd like to know if there is any way to influence or even control the rate at which ProgressEvents are fired by the URLLoader class. I have not been able to find at what rate it normally dispatches progress events either; is it at a fixed percentage per file or every x frames or milliseconds?
As these are local files, would I be better off not using the URLLoader class and instead switching to FileStream?
handling global keyboard events in Flex, is to attach a listener in the application complete event of a Flex application. However, no matter what I try, I have not been able to catch events without clicking on a point on the page, which is hosting my Flex application. Moreoever, if I use a Flex component in a web application, where there is also html and Javascript, I'd still like to be able to grap global keyboard events, even if the embedded flex component (in flash player) does not have focus. So is there a reliable method for connecting flex applications and components (when they're embedded in a web page) to keyboard events?
I'm working (for my sins) on a Flex 3.3 project, which unfortunately cannot be upgraded to a newer SDK version at this stage, and have hit an issue with the custom hierarchical tree class (subclassing mx.controls.Tree) we're using. Excuse the spelling; the previous developer had a fear of dictionaries...
public class HierachyTree extends Tree public function HierachyTree() {[code].....
I'm using a solution somewhere between these two methods (basically, implementing ITreeDataDescriptor) in order to add live text filtering to the component, and it's working so far:
public class HierachyTreeFilteredDataDescriptor implements ITreeDataDescriptor { private var filter:Function[code]..........
The issue is that (with tree:HierachyTree) neither tree.maxVerticalScrollPosition nor the protected property tree.verticalScrollBar .maxScrollPosition updates when the search string is changed.I've tried calling invalidateList() and invalidateDisplayList() on tree — and calling invalidateDisplayList() and invalidateSize() on tree.verticalScrollBar — to no avail.
I created a form dynamically by adding each component in action script,now i want to get back the text/data entered in to that each component dynamically?[code]...
I have a components and classes project library. Within the library, flex builder only seems to display content/code assist options for top level classes (e.g. arguments, Array) but not other classes such as VBox. Also, within the non top level classes, class properties are not provided by content assist.
I used HTTPService for reading xml, but I want only a particular xml field value like the first node id.The HTTPService object is:
<mx:HTTPService result="getid(event)" id="xml_coupon" url="###" useProxy="false" resultFormat="e4x"/>The getid(event) function is: public function getid(evt:ResultEvent):void
How to Read whole datagrid using Actionscript, that Datagrid contains Combobox itemrenderer and Textbox itemrenderer in two coloumn, I want to read the value of both the itemrenderer as well.
I'm new at Flex and I wanted to know how to read an xml file to pull its data into a chart, using Flex Builder 3.Even though I've read and done some tutorials, I haven't seen any of them loading the data dynamically. For example, I'd like to have an xml like the following:[code]and then loop through every "visitor" xml item and draw their values, and display their "fullname" when the mouse is over their line.
I want to read an xml file placed in the same folder as the swf. Note however there is no webserver running.
<![CDATA[
private var my_req:URLRequest = new URLRequest("assets/GmetadOutput.xml"); private var loader:URLLoader; public function startup():void { output.text="CheckPoint1"; //This is the only output that displays!
[code]...
So on the on CreationComplete event i call startup(); The Checkpoint1 output displays but none of the other checkpoints are reached? how to read a file placed in the same folder as the swf file!
I write object in a file. first i convert the object to bitmap data then i write it in a file. Now I want to read object from the file so that it returns the original object. How can i do this?
I plan to add other variables to the output time, so need to access each time and worked separately. I may also need to return multiple responses each with their own worked and time values. How do I do that. I was thinking to not use XML. Is there a more lightweight option. Flex shows I have the following options: array e4x flashvars object text xml
I have a simple AS3 class that just holds private variables. Each private variable has a getter function, but not all of them have setter functions. At runtime, Is there a way of telling which properties do not have setters but are read-only? Then I can decide to give the user an input field to edit the properties that have setters.
