build a dynamically growing or shrinking table with columns and rows. The cell backgrounds of the table will change color depending on an XML file.[url]...
I now need to design a chemistry periodic table. I will have a set of few elements that have been chosen by the user,and that should be reflected on the periodic table by making these few elements clickable.So when the user clicks on these few elements,corresponding explanation text will pop up on the text area outside the periodic table.Making all the elements of the periodic table buttons,so only the buttons that are within the set are enabled(clickable),while others are disabled.Embedding a static periodic table picture,and do things there(don't know exactly how yet).

When using a ColumnChart created in Flex 3, how can I to change the fill color of columns that meet a certain criteria?
Example: I have 8 columns representing agreement percentages between groups of people and want to change the fill color (or otherwise highlight) of all the columns that have over 80% agreement.

I am using FlashBuilder 4 and doing a simple application in flex. I am displaying a graph with 10 random values and based on the values I am trying to change the itemrenderer dynamically like CandlestickItemRenderer and BoxItemRenderer. Now my requirement was, if the values are > 10. I want to show my chart with CandlestickItemRenderer else i want to show the remaining spots as BoxItemRenderer. I am failing to do this. Either I am getting all the shapes as BoxItemRenderer or CandlestickItemRenderer. I am sending the code as a text file along with this.
View 1 RepliesI have been working with Flex and ActionScript for a few years now, but am just now getting into switching locales dynamically in one of my applications. I have set up locale bundles and have everything working well except for one thing I can't seem to get to change...the internal labels and date formatting on a DateField component.The DateField component is defined statically in MXML, but I am trying to change the dayNames, monthNames, and dateFormat attributes dynamically when a user changes locale, and it doesn't seem to work. have bound variables set up in the MXML that I am trying to change for all 3 of those attribute values, but they don't seem to change when I change the variable values.
I've tried making invalidateDisplayList() and invalidateProperties() calls after changing the values, but that doesn't seem to matter. I even added a call to "initialize()" after the 2 invalidate calls thinking maybe that needed to be called, but nothing seems to make a difference in getting the labels updated within the componentwhat I could be doing wrong? I've verified that the newDaysArray and newMonths array are getting set up properly from the bundle that they are being read from in the actionscript below.I should add that I've also tried editing the appropriate array variables in theSharedResources.properties file within the appropriate locales' framework_rb.swc library in my Flex sdk, and that hasn't seemed to do anything either.Here's code snippets:
MXML:
Code:
<mx:DateField id="dayChooser" formatString="{formatString}" dayNames="{daysArray}"

I am attempting to dynamically change the color of a subset/portion of text in a Spark TextArea control. Using the MX-based TextArea, I could leverage the mx.controls.textClasses.TextRange type and change the color directly as follows:
TextRange tr = new TextRange(theTextAreaControl, false, beginIndex, endIndex);
tr.color = somePredefindColor;
Input Parameters to TextRange constructor:
1st argument: The TextArea control that will provide access to the underlying textField property
2nd argument: Indicates the TextRange will not modify the content of the TextArea
3rd argument: The beginning index position in the TextArea text string
4th argument: The ending index position in the TextArea text string
How would I go about doing this for a Spark-based TextArea control? I am looking to dynamically change the font color for a range of text, not just the entire TextArea AND I cannot statically specify the font color. The problem I run into when trying to re-use the TextRange type is that the 1st argument is expected to provide the textField property, which is currently not on the Spark-based TextArea control. I thought about extending the Spark-based TextArea control to provide this accessor property but that seems like overkill and is probably not the best approach.

View 1 RepliesI'm using Flex 4 and I need to render the data that resembles HTML Table with row span in a Flex component.My inclination was to use a DataGrid but I believe that rowSpan is not supported for that component. I looked at the AdvancedDataGrid but the user does not want to have a tree-structure in any of the columns. Looking to see if there are any hints/tips for modifying the DataGrid or AdvancedDataGrid to produce an "HTML Table with rowspan" look.

View 1 RepliesI've just recently learned the PureMVC framework, and am a little confused as to the coupling between Proxy and Mediator objects. The links on this page connect to some documents describing the framework. (Please note, the links on the aforementioned page open PDFs.)
The diagrams and examples of PureMVC I've examined often show a direct coupling between a Mediator and Proxy. When the proxy's state is updated, rather than sending a new Notification, the Mediator (which retrieves a reference to the Proxy from the Facade) has its state updated.
This certainly seems to simplify the logic of the code, but it also directly couples two seemingly disparate components together. To my understanding, a Mediator's purpose is to translate Events from a view into PureMVC Notifications. Proxies are meant to perform some function to gather data and relay it back to the view. These two components seem to exist in different layers of the application, and perhaps shouldn't necessarily be coupled together.
Wouldn't it make more sense to have the Proxy objects send their own Notifications when their state updates, which are forwarded to the interested Mediator by the Facade?
I'm going to write an application with the Air/Flex-Framework. I'm looking for Best Practise and general Design Patterns for designing software especially in Air/Flex. I have experience with this framework but never had the pleasure to write a piece of software from scratch.
For instance: I stumbled across lots of software written in Air/Flex with nearly infinity global vars Most of the software I saw was not object-oriented How can I pack the asynchronous method calls nicely?
I'm familiar with general design patterns by gamma. I'm looking more for advise in designing good quality software with Adobe Air/Flex.

Is there are component in Flex where we can display the data in table format. [URL]..
I did not like the look and feel, any other components.
I have a table "template" which is used in various "instances". All instances have checkboxes in the second column (for record-delete).
What would be the most effective way of traversing the table and check if at least one checkbox is selected (to enable a "delete" button)?
I want to make a grid with 3 images in a row and then should the next row start. How do I that in Flex 4? Are there any controls or can you do it with the Repeater? Or am I forced to do some math on my own (modulus here we go again).
View 2 RepliesI have only worked on web apps for my whole career.I'm starting a new desktop (Adobe AIR) app project but I found myself having difficulties with:
stuck with thinking about overall UI design in the traditional page model
not sure how to handle the navigation part in the UI
not taking advantage of states
deciding what should be implemented on client vs server side, (or on both?).
I've recently just started delving into both actionscript and flex...the main reason being I like to create a sortable datagrid or datagroup like thishere you click the main entry that already has some detail and the row expands to show more.It might be possible to do with an itemrenderer but for the life of me I cant seem to find any tutorial or source or demo that doesn't assume you already know what to do with the itemrenderer since you cant just drop them in and have them work it seems.
View 2 RepliesI have sqlite table named categories with fields id, name, and parent_id. Sample data is much like:

I want to check there are no records in an existing sqlite table:[code]The customer table exists but is empty. While running it flex gives this error on result.length:Error #1009: Cannot access a property or method of a null object reference.
View 1 RepliesFlex has the notion of lazily loading data. It has a class named ItemPendingError which allows developers to handle it when an attempt is made to access data that is not yet available aka "pending".However, looking at the documentation it's clear you have to add try/catch blocks around your code wherever you have code that might cause an IPE (ItemPendingError) to occur.I'm curious if anyone knows why it works this way. I'm not sure what the best solution might be, but having to willy-nilly add in try/catch blocks to catch the error and then register a Responder with it feels bad and not very clean. And the fact that you sort of have to exercise your application to make sure you've caught all the possible places where the error might occur is also lame.Is there some other way or better approach that I haven't seen/heard of?
