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?
View 1 RepliesI'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('');".
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.

This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent.
dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
This is my custome event
package events
{
import flash.events.Event;
import ui.map.MapElement;
[code]...
In the main file, I would write[code]...
But if I want the component to have that behaviour innately, where do I write it in the mybutton mxml file to have it reference itself?[code]...
I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
I have a custom Flex 4.5 component (to be used in a List) -
Game.mxml (represents a clickable playing table in a card game):
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer [code].......
But I never see the "game clicked: " trace. Does anybody please know why? I'm probably missing something minor, because I can see the "Clicked: 8946" trace.
This is similar to the question asked here. I am dispatching custom event "ShopEvent" but i am getting error "Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent"Note: Error is thrown from the parent custom component (3rd code snippet), I have added more details thereThis is my custom event. See the first constant, I copy pasted the event name in custom components.
package com.events
{
import flash.events.Event;

The spark panel component for example can be written like this
<Panel title="Skinny">
<child components ... />
<controlBarGroup>
<child control bar components ... />
</controlBarGroup>
[Code]...
The motivation here is that I can now create a couple different skin files to change the look and layout of those subgroups. Reading source of the spark panel, there are some calls within the mx_internal namespace such as getMXMLContent() which is a method of the spark group component, but which I have no access to.
Does the description above make sense? How can I create custom 'contentGroups' in my custom Flex4 component that can use nested mxml child components? Should I approach this a different way?
ow do you display HTML formatted text in a Spark custom item renderer (Actionscript)?
Sample Code:
The html content in item.post_content displays as plain text in the IconItemRenderer messageFunction snippet below (which is just the default generated code for Icon Item renderer):
<s:itemRenderer>
<fx:Component>
<s:IconItemRenderer iconField="iconField"
iconWidth="64" iconHeight="64" labelField="post_title" messageFunction="getPost">
[code]...
I created a custom MXML component, TurboContent, that extends the NavigatorContent class:
<s:NavigatorContent xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">

In this case, the 'myButton' component never shows up, but all the elements of the base component do (3 buttons and a datagrid).
Before converting Flash into iPhone app, I still need to understand some questions.
1) Is the converted app able to read XML code from the website like RSS or custom script?
2) 3rd party API are not allowed to be download but assets like Images, sounds or reading data from MySQL db is allow?
3) Anyone port from Flex 4 yet?
I have made the following item renderer in mxml, but when I use it in a list for some reason I can not select it. Am I doing something wrong?

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.
View 1 RepliesI'm trying to make a simple flash application providing interface for taking tests as a high school assignment. One of the requirements is to use an XML file as data source.Now, having a List component bound to the XML file with questions consisting of data such as question body, question type (ie. single choice, multiple choice, open, image etc.) and possible answers (where applicable), I was wondering if I could add some additional data (and what is the best possible way to do so) to each question upon its transfer to the List component.
I am trying to achieve two main goals with this: firstly, to mark the questions to which an answer has already been given, like with such code in ItemRenderer class:
<s:Label color="{data.color}" text="{data.label}"/>
Where data.color would be set whenever the user gives an answer to a question.
Secondly, while at it, I thought of such possibility as a great way to store answers given to particular questions. In this case, the Class of the answer object would have been Object, since there has to be many type of questions (where the answer could also be a Bitmap for example).
while creating custom item renderers which interfaces we need to implement?
View 2 RepliesI have created a MyTreeItemrenderer extending TreeItemrenderer.
However, I do not want any label, folder, disclosure icon nor icon. I want to dispaly every node of the tree with my own graphic like eg: a line, round image etc.,
I have created a custom item renderer for the tree, i have added some children in create children function, my problem is that sometimes i need to show these children and sometimes i don't, depending on clicking on a button which also i have added at create children, the problem is that i had to create the item even if i don't want it to be visible, and removed it by making visible false, and this costs a lot of memory, i have tried to create it at buttons click listener but when scrolling the child disappears, and it may appear again if i keep scrolling up and down.. i am trying to add the child just when i need it to be visible, is this possible or i have to create it on child creation method?
