Flex :: Implementing Undo/Redo Within A TextArea?
Dec 2, 2009
Im wondering how to implement undo redo functionality with a TextArea. I already have an undoredo framework functionality working, now I have two questions.When do I start/stop a new undo/redo command, eg when a user hits undo, how far back do I go. How do I implement this(1.) in a normal TextAreay thinking:I thinking that I should create a new undo command, when anything but a alphanumber+space is hit. To do this I would use the keyDown event and test if the key is alpha num if it is not I will reset the command.

Loads an image to an Image component Transform the image (rotate, flip) with the Matrix Apply filter(s)
Now I am thinking about to create some undo redo functionality. Each time I do a transformation / add an filter I want to be able to go back to the previous image (before the action).
My thought is to have an Array and add the previous bitmap to the stack. But I see that there are some differences between transformations and filters I have also seen the ImageSnapshot and whot i can do and it looks like what I am after.

i've been unsuccessfully attempting to create my own undo/redo classes that work well with any type of possible undo and redo commands.
for example, my simple class works perfectly with undoing/redoing x and y positions of display objects or undoing/redoing values of sliders, etc., but things get dicey when i try to tailor my classes to also work with things like adding and removing items to a list.
is there any well known and well documented solution for general undoing and redoing for actionscript (without Flex)?

I am going to create an application in that i have to implement an Undo and Redo feature. In the application there will be multiple objects located on stage and user can customize the position of the objects. But when user clicks on Undo the object go back to their default position and after clicking on redo object will move on the new position. So my question is how can I apply these feature in my application? Is there any library or any third party classes?

I'm trying to work out how to use states in my Flex app.I've created two states, State1 and Stage 2. Both are based off the base state. I've created a few visual elements for State1, and given each of them includeIn="State1".But when I'm in design mode and click on State2, these elements are still visible?If I try to delete them while State2 is selected, all that happens is RemoveChild is added to the State2 tag.

I'm looking for suggestions regarding implementing process flow / work flow management in a PureMVC based application. Our Flex application includes a number of processes such as account creation, payment processing, etc. Within our team, there is some discussion of how rigidly we should adhere to the PureMVC model. Within the PureMVC model, it seems reasonable that the current state in the process could be managed in a Proxy. Commands are clearly responsible for processing the actions required of each node and for node transitions. Mediators for managing the UI.
However, I think that there is an important bit still missing here: a ProcessController. The approaches we've reviewed all seem to either violate the PureMVC model (even just slightly) or make unreadable code. A proxy would maintain the state of the process. As such, it seems to be an appropriate way to implement the controller. However, this is putting a lot of business logic into the proxy.

we have following class
[Code]...
If you run these, you'll notice that the MXML-component can't hear the event. The question is simple, is there some way of getting the Event-metadata tag to work WITHOUT extending EventDispatcher? I would like to keep this class independent and use object composition as much as possible. And no, I don't want to use ActionScript addEventListener in the MXML-file. It doesn't tell the developer anything like good old Event metadata tag, and besides, that is not the point of this example. :)

Are there any differences implementing Flex application security in a clustered Java environment (such as Oracle Application Server/OC4J or a JBoss cluster) vs a single application server environment? (And/or does it depend on the specific environment software?)
What considerations are there in a situation where you need to authenticate with LDAP (AD) and store user access information in a database (ex. USER table containing username + permissions/roles info)? Any differences between Blaze DS and Granite DS?

I would like to implement the MVC pattern to an existing Flex project.I want to separate out the controllers and models from the views. They currently all live together in large mxml files.My question is, should httpservice requests be in the model or the controller? What sort of advantages/disadvantages would there be to either?

I have an application that is coded using Flex 3 on UI side and java @ the service layer, along with BlazeDS. Now we need to authorize the users accessing the system based on the roles that are defined for them in the database, e.g. : say a user with role guest should not be able to access Admin tab on ui and also should not be able to do any operations other than viewing the data displayed on dashboard. Also the point to note here is that roles can be created dynamically by Super users from UI. I came across this link which describes how to perform Role Based Authentication & Authorization. With this approach I need to define the roles in service-config.xml but since my roles are not pre-defined I cannot go with this.

I am attempting to implement a layout in Adobe Flex 4.5 / MXML where I have multiple controls in an HBox that - in total - consume all available horizontal screen estate. Some use a relative with (percentage), some an absolute width (pixels) and one is supposed to consume whatever space is still left, such as:
+----------------------+-----------------------+------+
| 35% | fill parent | 10px |
+----------------------+-----------------------+------+
How would I achieve this in Flex (is there something comparable to Android's
layout_width="fillparent")?
Due to the fact that there are elements that have an absolute width I cannot easily calculate the width of the filler as a percentage a priori (as it varies with the screen width). Setting the filler's width to 100% also does not work as this will shrink the 35% area below 35%. Applying the updateDisplayList suggestion from www.Flextras.com's answer below yields the error "Call to a possibly undefined method updateDisplayList" at the line marked in the source excerpt below:
<?xml version="1.0"?>
<mx:HBox xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"

A little much put in the title, but my question is just that. I have the following AS3 code for my textarea...
addChild(Texta1);
Texta1.alpha = 0;
Texta1.blendMode = BlendMode.LAYER;
[Code].....
Unfortunately, when I start placing text in this text area. Either through code or user input, the text will be placed on a new line after about 80-100 pixels. Yet I want it to start a new line after 320 pixels (it's length).

If you have two text areas with different styles (fontFamily, weight, color etc) and you copy text from one to the other it also copies the style from the originating text area. Is there any slick way to prevent that?
Here is a sample of code that will illustrate the problem. Type some text in the top box and some text in the bottom, then copy some characters from the top box to the bottom. I'm not using htmltext.[code]...

I want to implement an application in Flex/Rails in Background as I know these two languages but I'm fairly beginner with Flex and Intermediate-to-expert with Rails. My application will display a calendar like object by which there are say 5-day week or 7-day week or a month (30-days) and in each day there will be some data such as appointments or such. I want users to be able to drag left or right to get more days after or before the displayed week for example and I want the boxes to be filled with proper appointments data.
What is the best way to implmenet this in your opinion, mainly from Flex point of view? Any architectural tips from the Rails side?

I have an mx:TextArea and I want its height to be the same as its content height. There is nothing fancy - just a text area and text that is not editable. I need a simple and reliable way to make the control fit and show all the text without vertical scroll - something like auto resizing. Also my control's text will be set only once and will not change as it will not be editable.
<mx:TextArea id="myTextArea"
editable="false"
width="100%"
verticalScrollPolicy="off" >
<mx:text>
[Code] .....
There is one more post here on the same topic but it is not relevant to me because the setup there is a lot more complicated as it includes styling and binding.
