I have an application written with Flex 3.6 and when I create a modal popup dialog, the buttons and text on that popup do not work correctly with the Accessibility properties that I have defined. The app is compiled with the accessibility flag. I build a simple app to test demonstrate the problem.
[Code]...
The Accessibility best practices for Flex page from Adobe website list four strategies to enable accessibility :
[Code]...
I test if the accessibility is enabled by checking the value of Accessibility.active, which is always false in my sample application containing only a datagrid and some buttons, using the four above strategies. As I'm new to Flex, I don't really know where else I could search to enable it, and no, Accessibility.active = true; isn't a solution, as it's a read-only property
I use this code to create and show a MessageWindow:
var newTitleWindow:MessageWindow = PopUpManager.createPopUp(contextView,MessageWindow, true) as MessageWindow;
newTitleWindow.text = message;
PopUpManager.centerPopUp(newTitleWindow);
[Code]....
There is no nested components displayed when I run my app.
The debugger shows they are created and visible.
To my "amusement" the components are shown when I replace s:TitleWindow with mx:TitleWindow.
I really want to use spark TitleWindow.
I'd like to know if it is possible to enable/disable some piece of code according to Flash Player version in ActionScript 3.
Let's say; I have a custom class customClass that uses flash.media.Microphone. The Microphone class has a property isSupported which is available for Flash Player version 10.1 and above (as stated in the documentation). I implement this property in my customClass... so:
I need something like this (by checking with the built-in Capabilities.version):
if (version >= 10.1) {
trace(_mic.isSupported); //this will throw an error if the debug version is not 10.1 or later
} else {
doSmthElse();
}
To create loader for external swf that will have features to enable/disable sound and to enable/disable external link requests.I don`t have source files for that external swfs.
View 2 RepliesI'm a blind developer who is considering learning Flex. According to this link when you compile a flex application with the defaults it isn't accessible to screen readers. Why is this, are there performance issues I should be aware of, or was this just an arbitrary choice Adobe made?
View 2 RepliesI have a flash based Air application I'm trying to add keyboard accessibility to (not flex).
My problem is that MouseEvent.CLICK is not being broadcast when tabbing to and hitting enter on an interactive movieclip.
The yellow hilight rectangle shows up around the movieclip fine, and the same code works perfectly if it's compiled into a non-air swf.
Is there some difference in keyboard interaction when compiling to Air?
I need to make a small app accessible to screen reader.I'm managing to make buttons accessible, but I would also like to have a section of text accessible by screen readers so that users can hear what the text says.
I can't seem to work out how to do this.. I've tried various text controls and set them as focusEnabled, tabEnabled, i've set the accessibility* attributes too but it never seems to work, I cannot tab to a text label and hear the content.
I'm honestly a little new to accessiblity in Flex so apologies if i'm missing something obvious.
How to add accessibility requirements to a swf created using mxml+flex sdk? I have a few buttons and textfields in the swf and the impaired user should be able to increase the button size and text size while using the swf. I've looked into flex built-in accessibility features, but its not what I require. I want to run the swf standalone without a browser, so preferably change the size with a visual widget.

View 1 RepliesI'm working on a mobile app using the Flex 4.5 SDK and I'm trying to figure out the best way to handle notification windows. In most cases these windows will be alerting the user to when something goes wrong. Ex: bad login, no data, cannot resolve server.
I'm using a singleton design pattern, I have a Requests class that handles server calls. Most popups will be originating from this class (IOErrorEvents from my loader being used to access the API). Since this class is a singleton and is used from all Views inside the app it is not aware of applications current view. I'm also not sure having this class keep track of the current view and having it push popups on top of it would be best practice.
I'm hoping that I can use PopUpManager to keep track of where to add popups and what popups are currently on the stage. Though all examples I've seen online about this show static Components being used in a views Declarations tag.
I had to reformat my question because I realized I was using incorrect flex method. But still a similar issue occurs:
private function passForm():void {
PopUpManager.addPopUp(passTitleWindow, this, true);
PopUpManager.centerPopUp(passTitleWindow);
[code]....
I click and popup does not display.
Is there a easy way to figure out consistently when a Dialog closes that has been created through PopUpManager. I would have suspected some type of message or callback mechanism, but there does not seem to be. In one case I use the WindowTitle component and event that only fires the CLOSE if someone presses the close and give no message when the dialog actually closes.
View 2 RepliesBasically I am poping up the following component:
PopUpManager.centerPopUp(PopUpManager.createPopUp(this,RegionExperienceDetailPopUp,false));

What is the syntax to do this?
I'm using the PopUpManager to bring a bunch of event windows up.I want to make it so that only one window can be open at a time, but I don't see anywhere in the code that tracks open windows to set up a conditional. I guess it just creates the windows and then sets them free?Thinking about a windowCount variable that increments when I add a window and decrements when I remove one, but since the PopupManager is called in different classes I'd have to start throwing events all over the place. I can do that, but I'm wondering if there's a more straightforward method?

View 2 RepliesAs the topic states, using a Rich Text Editor with a PopUpManager makes typing slow. If you try it in Firefox/Mac, it is painful. Chrome/Mac is a little slower as well. Are there any known issues with the PopUpManager and performance that can be addressed easily?

View 1 RepliesI'm using PopupManager to display (not modal) popups in Flex.How can I make the background of my TitleWindow popup completely transparent?Now it is semi-transparent.. see picture with semi-transparent background (i.e. I just want the label inside visible):

Maybe, instead of making it transparent I could try to reduce the padding, in order to make only the children visible ?
I'm trying to organise my code better and figured it would be good to place the pop-up logic within the component that's being popped-up. However, I can't seem to do this without causing one error or another. I also need to make the pop-up modal.I'm doing something along these lines (psuedo code):
<mx:TitleWindow >
<mx:Label id="messageLabel" />
<mx:Script>

How can I make a DisplayObject popup like Flex PopUpManager in AS3?
View 1 RepliesI'm fairly experienced with Flex 4, but I still haven't needed frameworks yet (I like to do everything myself) and don't want to use them either, I know it's advantages and have learned how to use one of them, but still, no.
How can I dispatch an event in the main application and have a component inside a popupmanager to react to that event? All this dispatching the event within the main app and NOT aiming it to the popupmanager or the component instance, I want to be able to fire the event and not care about who gets it or if anyone reacts to it at all so if that is possible then I wouldn't care about keeping track of said popups.
I already dispatch an event from the component and receive it in the main application by bubbling the event and therefore being agnostic of each other, now I want it backwards.
I am implementing an application timeout feature (flex4). What I am finding is that mouse and keyboard events, which I have listened to with :
FlexGlobals.topLevelApplication.addEventListener(MouseEvent.MOUSE_MOVE, resetLastActivity);
FlexGlobals.topLevelApplication.addEventListener(KeyboardEvent.KEY_DOWN, resetLastActivity);
are being masked by the existence of any popup windows. The code is in a component, in the constructor. The component is added to the main application in the block.
How can I get these system generated events to not get stopped by PopUpManager display objects?
In Flex (Flash Builder 4) I am opening a new window via PopUpManager.addPopUp. I have timer code that runs in my component and I need to stop my timer when that window opens and start the timer again when the window closes.
I figure it's easy enough to stop the timer in the function that opens the window, but how can I start the timer again when the window closes?
Is there a way to tell if there is a pop-up window in front of my component, or if a specific pop-up window is still open via PopUpManager?
My Flex 3 application has some modal dialogs displayed via the PopUpManager, but there are times when I'd like other view components to know there is popup displayed. The PopUpManager doesn't have any method for actually checking the existence of popups. Is there any other way to detect this in flash/flex without writing my own global manager?
(also systemManager.popUpChildren.numChildren == 0 even when there's a modal popup)
I'm trying to open/close a TitleWindow using PopUpManager.addPopUp() and PopUpManager.removePopUp() while reusing the same TitleWindow instance. I noticed that the creationComplete() is only called once for TitleWindow even if I open it several times and was wondering what events I should listen to for the succeeding popup loads.
View 1 RepliesWhen using the PopUpManager in Flex with modal = true, the background application is blurred. Is it possible to keep this blur for most of the background application but set certain components to not be blurred?
