Actionscript :: Flex - Create Buttons Dynamically And Assign Value From Text File?
Jul 17, 2011
I made a basic text editor that lets users insert predefined strings into the document with button clicks. What I need to do now is let the user define their own buttons and string values. For example I have a button that inserts "Hello" into the text. The user may want to create a button that adds "Goodbye".To accomplish this I figured I would create a .txt file called buttons.txt or something. i would readutfbytee, loop through it to create the buttons. problem is I know what I want to do but not sure where to start

I am building a Flex application with ActionScript 3. Unfortunately I've hit a wall with this one...I would like to be able to apply an upSkin to my dynamically generated button like this:
//this theSkin variable is dynamic in my app, but for this example it's a simple string
var theSkin:String = "http://www.mypicturedomain.com/images/myimage.gif";
var navBtn:Button = new Button();
navBtn.id = "thumb1";
[code]....
When I attempt this, I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Loader@3dac941 to Class.
How do I skin this button with my image dynamically? A couple of things to consider:The upSkin image must be remote. It can't be local.The button must be generated dynamically (it's in a for loop).

I've created an XML calendar (with code from an example I found online) and now I want to add some additional functionality to it. Here's what it currently looks like:When the user clicks on a day with events, they are listed to the right of the calendar. I want the user to be able to click on an event in the list and have that load the details, including an image and colored category bar into the Details pane on the right. The reference to the image and category w/ corresponding color bar will be defined in the XML file along witht the details.Here is the current code for displaying the events:
Code:
// show the event information when a date with events is clicked
calendar_ec.onDisplayEvent = function (eventsData, dateObj) {

I have 3 movieclips on stage (inn0, inn1, inn2), each have a textfield as child. I want to do something like:
Code:
for (var i:int = 0; i < arrayWords.length; i++){
"inn"+i.botNewTexto.text= arrayWords[0]
}
I can do:
inn0.botNewTexto.text= arrayWords[0]
inn1.botNewTexto.text= arrayWords[1]
inn2.botNewTexto.text= arrayWords[2]
But want to do it dynamically.How can I do that assignment?

I've seen similar threads but couldn't find one with the exact same issue. I've a PDF / Word document with arabic copy when I try pasting that text in flash all the joined letters start appearing as individual letters.I've tried the dynamic text box solution in which you create a dynamic text box and assign the text to its variable that doesn't work. But strangely when you write arabic in dynamic text box (with out assigning the text to the variable) and double click to select the text box and its content the text starts appearing fine .. but when published its again all individual letter.

I am trying to create html links from a external xml file to be dynamically added to a text field (im using flash builder)the process i am having trouble is: -Loading an external swf which contains the textfield loading external xml which contains the cdata with links adding the cdata to the htmltext property of the textfield the link is showing correctly, the mouse turns into a hand... but when i click on the link it doesnt work. i have seen a few forum posts similar to this problem but all are using textfield control in flash builder but im trying to add the cdata into an externally loaded swf which holds the textfield.

xml values are stored in 'arr' array collection. depending on the length of the array stored, the below described components are created and assign those values to relevant components dynamically. For Example:

I've made a component based on a mx:TitleWindow that contains linkbuttons that I'm using as a context-menu. The TitleWindow component contains link buttons like this:
[Bindable]
private var _showEmailThis:Boolean = false;
[Bindable]
private var _showApproveThis:Boolean = false;
[Bindable]
private var _showReviewThis:Boolean = false
[Code] .....
This component contains a large number of links and is re-used by multiple modules in the same application. Within each module, this component is used when a user clicks on a row in a datagrid. The code looks like this:
In "Requests" module:
private function dgRequests_click(event:MouseEvent):void {
menu.showApproveThis = true;
menu.showReviewThis = true;
}
In "Performance" module:
private function dgPerformance_click(event:MouseEvent):void {
menu.showEmailThis = true;
menu.showReviewThis = true;
}
As you can see, the visibility of individual linkbuttons is controlled within each module by setting boolean properties. If I alter this component to use a renderer, how can I control the visibility of the linkbuttons from the code in each module (there are over a hundred links with different functionality - not every link will be used in each module)? Note: it is not known from the back-end which grid within which module uses which link. This is set in the front end within each module's actionscript file. E.g., if the XML looks like this:
[Code] .....
And I set the Email link to show in the module like this:
private function dgPerformance_click(event:MouseEvent):void {
menu.showEmailThis = true;
}
How do I make it take effect? Is there a way to control the visibility of a linkbutton within an item renderer in a component from the module that uses that component?

I am amateur in flex, and started my final year project in flex to learn it, I am stuck in place where I have to create rows of drop down lists when the user pressed add more, E.g.: like the ones in mail attachments. I think I have found a way to generate rows, I am not even sure whether it is a correct way, how I generate the rows:
<mx:states>
<mx:State name="newRow">
<mx:AddChild relativeTo="{cityDropdown}">
<s:DropDownList id="newbutton" creationComplete="hotelDropdown_creationCompleteHandler(event)" labelField="Name">
<s:AsyncListView list="{getAllHotelResult.lastResult}"/>
</s:DropDownList>
</mx:AddChild>
</mx:State>
</mx:states>
Now when I generate more rows the dropdownlist ids will conflict, so I want to know a way to generate ids, I think I cant even call a function in there.

I want to dynamically create multiple buttons on the stage. The number of buttons I want to load will eventually be retrieved from an XML file.
I've made some progress but I'm a little stuck. I have no problems with the XML at all. I've created a button with rollovers and given it a linkage class name and it can be added as a child to the stage.
The problem lies with creating multiple different buttons, each with unique button listeners.

Having got into flash about a year ago, I have a fairly good understanding of as3, but I have never had any reason to learn as2. For an upcoming project, we were looking to use Scaleform GFx, with the UDK. (Unreal Development Kit) Trouble is, Scaleform only supports as2. From what I've been told, as3 is supposed to be better in just about every way, so I really don't want to learn a language that?s most likely on the way out, if I have any other options.
Is there any converters out there, that can convert script from as3 to as2? Or another workaround possibility, since flash communicates with the UDK by means of just calling a function, could I create an as2 file that could dynamically load an as3 file?

What I need to do is assign 5 separate dynamic text fields to 5 seperate buttons and at the same time to those same five buttons i would like to add 5 images that i would be able to change merely by swapping out the images in the file theyre in on the server.I would also like to get a nice transition between the images...ALSO i want to dynamically load the images for the buttons that will be used for switching from picture to picture(which im thinking i will be able to do after i know the how to do point the aforementioned things.)
Through tutorials I've found around the net I've been able to get most of the parts together... but i get lost because what they show you for AS2 they don't for AS3 and vice versa, at least that ive seen.so... I guess my question is... would i need to set up 5 seperate dynamic text fields on the stage and then set each one of them to one of the corresponding button. If so what AS code would i need to use to do so. And if not what would i need to do?
The other part of the question would be I know about the UILoader... would i be able to use it as my buttons and images, if so would i need 5 seperate ui loaders for both the Thumbnail buttons and the images or is there a way that would be better to do it? and once i do that would i do the transitions using frames and tweens like with AS2?

This question relates to the gallery that I'm working on; basically, I am now trying to add text comments which change according to which button you press to the images. I know how to make this work by applying actionscript to each individual button, but I would like to put all of the actionscript on one layer, meaning that I would have to use the 'button.onRelease = function ()' operation instead of the 'on (release) { function" operation.The code is a variation of Kirupa's code for the tutorial on loading information from an XML, and the xml is his completely. Here it is so far:
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;

I need to create two combo boxes that are populated by an XML file. In the first combo box there are 13 choices and depending on what the user selects I need to populate the second combo box with the correct information. Now I can create the first combo box just fine but when I try to dynamically create the XML file name for the second combo box it doesn�t seem to work. What I am doing so far is taking the data from the first combo box and adding the quotes and .xml with this piece of code:
PHP Code:
pModCombo = '"'+event_obj.target.selectedItem.data+"Combo"+".xml"+'"';
pModComboXML = new XML();
pModComboXML.ignoreWhite = true;
pModComboXML.load(pModCombo);
If you trace that code it creates the file name just fine however the xml file will not load. If I replace that code with the normal xml code like this:
PHP Code:
pModComboXML = new XML();
pModComboXML.ignoreWhite = true;
pModComboXML.load("new.xml");
The second xml file seems to load just fine. However, if I create an if statement with all the different xml file names I will have to update the swf every time I add a new choice in the first combo box. So my question is does anyone know how to dynamically create the xml file name?
PHP Code:
pmComboXML = new XML();
pmComboXML.ignoreWhite = true;
pmComboXML.load("brands combo.xml");

I'm currently building a create-your-own t-shirt application using AS3. My client needs the resulting design as an Adobe Illustrator file for printing. Is there a way to dynamically create an AI file from your Flash app? The only solution I have been able to come up with is recreating the design in a special version of the app that only the client has access to (the app would automatically load and create what the customer designed). This version of the app uses PrintJob to create a printable version of the design that the client saves to a PDF and then opens in Illustrator. It works, but as you can see, it's a messy process and creates additional steps for the client.

I have the following AS2 code which creates dynamic buttons based on an array:
Code:
var labels_array:Array = new Array({label_txt:">> arquitectura industrial", gotoX:"partners"}, {label_txt:">> edificaci�n", gotoX:"team"});
var initX:Number = 0;
[Code]....
the variable nextX places a new button every given number of pixels, in this case 140px. What I'll like to do is to make this value dynamic so that a new button is placed taking into account the width of the preceding button, plus a certain number of pixels.

I have to create a web page which can be set to full screen(I mean the real full screen,not like press the F11),in the full screen there should be some words displaying.
Take the [URL]
Normally,it show its contents(the questions),but someday,maybe a VIP come to visit the page,so we want to replace the whole page with a welcome screen.
Of course we can replace the [URL] (suppose it is the index page) with the welcome text(welcome xxx to our site...) in the server side.
However this is not convenient,and the text can not be full screened.
So I thought the flash,I can add a controller button at the page,when required,I click this button,and set the welcome words,then a flash will start to play with the sepcified words in a full screen model. It would be better if the flash can show the text with a Animation.
I have never did the flash development,so I want to know if this is possible?
BTW,can all the clients change to flash with juse one click?
I mean I click the controller button,then all the client who is visit this page should see the contents replaced by the flash at the same time.
