ActionScript 3.0 :: Creating Many Textfields And Adding Code At Runtime?
Oct 20, 2010
I have a flash project that requires a swf file with over 300 textfields i.e a datasheet like in excel.i use actionscript 3 to dynamically add them at runtime.However I have a function calculate() that references them at compile time.So i think the problem is the caluclate() cannot find the textfields because they are still not added to the stage.How can i create them dynamically and after that add a function caluclate that will surely find the textfields?
Here is a code example of my work:
//add 50 textInput components
for (var intr:Number=1; intr<=50; intr++) {
var intTextField:TextInput=new TextInput();
I'm currently creating an app which allows users to select blocks of text from a List and dynamically create a TextField on the stage.I'm calculating the height of the TextField and positioning the next TextField beneath.I'm also recording the total heights of the TextFields so that I know when the total height exceeds the available height, at which point I move the x position and reset to y position to zero.
When the next TextField will exceed the available height I want to split it into two, so I'm calculating the remaining height, making the TextField.height into the remaining height.when I try to get the position of the last visible line.If I have the TextFieldAutoSize as LEFT, then I can dynamically generate the heights of the TextFields.For the final TextField in the column I need to set TextFieldAutoSize to NONE so I can change the height of the TextField. i.e. I don't want it to autosize.However, bottomScrollV returns the total number of lines, not the last visible line.
I can create the required behaviour in a separate doc but when I copy the code into the loop it fails.Here is the code.
Code: public function buildTextFields() { 3 columns (I'm calling them TextBlocks) // so the first is 0;[code]....
I've seen the Loom project, but are there any alternatives that are more mature (and actively developed)? I am looking for something that would allow load-time weaving of pointcuts into existing binary code at runtime with the AVM2 runtime.
Im having is that I cant update the information that I get from my XML file at runtime. I have some static textfields that updates just fine, but it�s the dynamic ones that don�t play nice.
The project is a small display that shows the amount of minutes that is left from the time set in the XML to the current time. I don�t want to bore you too much with the details of it all.
Heres the code! Right now though it doesnt update at all. Removed those bits of code since it got me nowhere
Code: var container:Sprite = new Sprite(); bottom_mc.addChild(container); var loader:URLLoader = new URLLoader();
I had a problem with ScrollPane. My application consists of two Buttons(with instances: myBtn1,myBtn2).I added textfields to a movieclip(myClip) and again added this movieclip to a scrollpane(sp) using the code as follows:
var sp:ScrollPane = new ScrollPane(); var myClip:MovieClip = new MovieClip(); myBtn1.addEventListener(MouseEvent.CLICK,onClick);function onClick(evnt:MouseEvent):void {
let's say you had a dynamic text field with a number (for example '30'). Everytime you click on a certain button / movie clip, that triggers an animation (so far no problem) AND adds '20' to the number in that textfield.
==> first click, the number displays 50 (30+20), second click 70 (50+20) ...
When you enter a certain keyframe and that number is higher than let's say 290, the movie jumps to frame x. If that number equals 290 or is lower than 290, the movie jumps to frame y.
Basicly I'm adding dynamicaly sprites and textfields, which i populate from xml, in for loop. I'm building sort of table, so for every sprite, I'm adding new data in textfields.I've loaded xml and passed data to 2 xmllists, both traced and doing fine... Later on I add data from xmllist to array which then I'm looping in for loop.Problem is that from 1st xmllist, 6 out of 7 textfields are visible, 1 can't be found nowhere :/ from the 2nd xmllist only 1 out of 4 are visible...I've tried everything, tracing them returns that they are visible, on good position, filled with text, contrasted color from background.
PS: here is the part probably causing the problems.. for(mojbroj=0;mojbroj < dohvatiosamih2;mojbroj++){if(mojbroj%2){lista.graphics.beginFill(0xdddddd);lista.graphics.drawRect(150,prenesi+(
Im trying to create several TextFields using function recursion.
arr_HelpRubrik = new Array(); arr_HelpRubrik = [1, 2, 3, 4]; var x_pos = 10;
[Code]....
What it does is look for the existence of a textfile (HELP_i.txt) and if it exists, create a TextField into which it is supposed to output the contents of that file. So Im supposed to have as many textfrelds as there are textfiles in the end, all situated in a kolumn.
Well, what actually happens is that every textfield is correctly created, but will close as soon as the next one is created. So I end up with only one textfield.
Im creating many textfields dynamically and I dont want to have to repeat the same code over and over for each field. Currently I have something like below which deosnt work.
I have a series of dynamic textfields added to the stage via this code:
ActionScript Code: function addTextfields(){ initTextfields++; var question:TextField = new TextField();... question.type = TextFieldType.INPUT; quesTextArray.push(question); addChild(question); question.addEventListener(FocusEvent.FOCUS_IN, handleFocusIn); question.addEventListener(FocusEvent.FOCUS_OUT, handleFocusOut); }
Using FocusEvent, I want to add a UIScrollbar to that event.target TextField. Here's what I have (that's not working): ActionScript Code: function handleFocusIn(event:FocusEvent):void{ var mySb:UIScrollBar = new UIScrollBar(); mySb.direction = "vertical"; mySb.setSize(20, event.target.height); mySb.move(event.target.width+event.target.x, event.target.y); addChild(mySb); trace(event.target); mySb.scrollTarget = event.target; }
My dilemma is with scrollTarget, I'm not sure what the actual target should be. I thought event.target would do the trick but I get a 1118: Implicit coercion error. When I trace event.target I get [object TextField] so I thought that's all I would need to do.
I have a for loop that runs depending on the length of an XML file. What I want to do is create a unique text field for each run through of the loop, and give it it's own position on the stage, and finally assign it the text from an external text file that is specified in the XML file. Everything I know how to do except creating the textfields.
Quote:
for(var i:int = 0; i < blogXMLList.length(); i++) { var txtHolder:TextField = new TextField(); txtHolder.x = textX;
[Code].....
This code creates only one Text Field, but then replaces it's text with new text with each run through.

My problem arrives when I try to get the position of the last visible line.If I have the TextFieldAutoSize as LEFT, then I can dynamically generate the heights of the TextFields.For the final TextField in the column I need to set TextFieldAutoSize to NONE so I can change the height of the TextField. i.e. I don't want it to autosize.However, bottomScrollV returns the total number of lines, not the last visible line.I'm at a loss.

And it works. My question is what code to put to replace trace(xmlData); with code that will allow me the XML components be arranged in textfields. Here is how my XML is constructed:
[Code]...
What code to put in AS so when i start naming my textfields tf1,tf2,tf3,tf4 each line from the XML to go to its text field (like first line from the XML goes to tf1, second line to tf2 etc.)
How can we create an SWF out of runtime created objects in an SWF.OrSaving Runtime created objects.The idea is to create an interface in flash that can be used to create some animations , saved , and later used.
I have a MovieClip with multiple child MovieClips. I would like to add a class to each child MovieClip. Unfortunately, I can't just create the class and mc.addChild(class) because classes aren't display objects.
I am trying to ape the MS Paint application in Flash. I have a small point that I want to get cleared. I want to set the thickness of the line that I am drawing.I want to add a numeric stepper to stage dynamically. Only when I click on option to draw line the numeric stepper must appear on stage. It must be removed when I select another component.How can I add it at runtime. I got tutorials and references in which the stepper is always there on the stage. But I want it only when I want to draw the line.
Been struggling with the basics of creating instances at runtime. I needed to implement an XML video player and even though the client has supplied a component that they liked and it works fine, i cant turn it off as im not sure how the thing works. Basically the timeline hits a keyframe and stops. It runs the code to make the player popup but once the user has exited, the player stays on.If the function creates an instance for flv playback... how do i tell it to stop?
function below function makePlayer ():void { my_player = new FLVPlayback();[code].........
I'm working on a project that uses a lot of "widgets" that are displayed in the main application. Many of these standalone swfs where the same code is incorporated several times ( for instance TweenLite ). I want to optimize this by removing this added code from each widget to reduce load time. I'm working on Flex Builder, but this is an actionscript/flash project. I'm not sure how I should do this
I'm trying to create a container movie clip, then inside that, create several other movieclips with an image in each and display them with an offset x.It does the offsetting but only displays the last one at the last x.When i dont put the clips in a container it works fine. but i want them in the container so that i can movie the container around on a press.
Heres the code:
var itemsArray = new Array("pic1.jpg", "pic2.jpg", "pic3.jpg", "pic4.jpg"); var clipArray = new Array(); _root.createEmptyMovieClip("carousel", this.getNextHighestDepth());
I'm loading a set of images and text from an XML file.I have the images loading into empty MovieClips created dynamically using 'createEmptyMovieClip', and I can get the text into dynamic textboxes that already exist on the timeline, but this isn't exactly what I want.
What I wan't to do, is to pull the text from the XML directly into dynamic textboxes at runtime, in the same way as the images.I've read today about 'createEmptyTextField', but I can't get it to work.
Any way to take the contents of an array, which is full of texttype, and use them to create a stack of buttons. Now the actual text I have in the array will change every time the program is run. For example, let's say my array is ["apples","oranges","pears"]. I want to create three buttons (in this example) so that it appears apples oranges pears And when you click on "apples", it takes you to the corresponding "apples" webpage ("_blank").
I am writing some code that needs to be very efficient, yet flexible. This is in a class and when the class gets initialized a function is setup. I want this function to run straight through without doing any time-consuming things such as calling other functions or routines, or doing any if/else logic/branching. Now I know that you can setup a function at anytime during runtime such as:
Code: var myFunction:Function = function() {trace('HELLO!')}
But what I am trying to do is to try and append code to a function based on logic, yet I don't want the function to be deciding this logic when it is running as it will only need deciding when the function is created.... imagine if it were a string it would be something like myFunction+="do somethingelse;" which would be the same as having initially setup myFunction as such:
Code: var myFunction = function() {do something; do somethingelse;}
With this I seem to be having no luck Here's an example where I setup the most compact/efficient function at runtime depending on what I want the function to do. Now this was fairly simple because when we create the function there are only a few possible variations, but I need someway of doing a function+= as my real code has quite a few variations and it would be a nightmare have a zillion if/else branches. REMEMBER I do not want any logic/decisions in the function itself as it to be the most efficient the function must be as compact as possible and run straight-through.
Code: var dynamicFunction:Function; // // Setup the dynamic function & call it // In this example outputs "Hello Jim" & "Goodbye Jim" dynamicFunction = CrapSetupRoutine(true, true, "Jim");
[code]....
P.S. I knew the += would never work as this is a function and not a string. But at least if you think of the function as a string you'll get what I'm trying to do....
I need to create curved Arabic text which can be change at runtime by input from Text Field. Currently I am using Text2Curve AS3 component. It works fine with Latin symbols, but I have several problems with it when it come to Arabic text: First problem is that Arabic letters comes in four different forms: end, middle, beginning and isolated. But Text2Curve AS3 component shows them the same.Second problem is that Arabic text shouldn't have any gaps between letters. But in component you can only set one letter spacing for all symbols. So some of the symbols overlap, while other have gaps between them.Third problem is that Arabic text is written from right to left, but Text2Curve AS3 component only supports left to right. (I solved it partially by reversing input string)If someone have had similar problem, or know better component/library (paid or free), or can event create one please let me know. Also I am working with Adobe Flash Professional CS 5.5 and I don't speak Arabic. So it is quite hard for me to check if Arabic text is good or not.
Basically I want the user to be able to create a line on runtime by first pressing mouse_down on the stage estabilisting the first xy points of the line and then move the cursor somewhere else to a different x, y co-ordinate where the user finishes the line by pressing the mouse_down button again. How to do this? I need it to be a straight line

THE CODE ABOVE DOES NOT WORK ,I want to create 10 moveiclips each with unique name, which I can move around or maybe load things into later. At the moment the trace returns 'undefined' so the movieclips aren't even being created.
