ActionScript 2.0 :: Maintaining Multi-line Formatting?
Jan 28, 2003
I have a project which, for all intents and purposes, attempts to create an online text editor/word processor. The key thing is that I need all multi line formatting to be retained and sent to the server. ie, if the user enters a bunch of text (all colors/bold/fonts and stuff are working great) which has a carriage return or a line wrap, I need a way of tracking that and inserting some kind of flag to let the server now to break to the next line at that point.this project is a client/server application so just storing the text string and expecting flash to be able to use the same size text box will not work.
I have created a function that detects keypresses and MOSTLY takes care of the carraige return issue (still not as solid as I'd like though). Basically, every time the user presses return, I store the length of the string and, when parsing the data for transfer, I insert newline chars at every index point where one is needed. This mostly works unless the user goes BACK and enters a return (still working on that little issue).But the word wrap part is killing me. I did find several discussions of using either total characters to determine how big the box is and where to break the line, or something along those lines, but here's the main issue with that:everything is dynamic. the user can change almost everything, from text font (so there will be variable font widths) text size (again, variable widths) to textbox size (so I can't go with a fixed pixel size to break the text). I've noticed that it was very easy to make a text box vertically dynamic, but the width seems to want to stay fixed (if set to multi-line) since the user will be changing this width, I'm just stuck.
if it means coding a huge set of functions that compares every possible font (i will be using embedded fonts eventually so they will be limited) with every possible size and then using that data to determine box size, that's fine, I'll do whatever I can to get this working, but there just has to be an easier way

I have a TLF editable field in a(n) swf file. Text entered there gets sent to a php page where everything is processed. I had the behavior set for multiline, but just realized that if someone hits return and keeps typing, no break is displayed (not even a space). I've tried using nl2br() in the php when it grabs the POST variable from flash, but that doesn't work. I don't know how flash handles the carriage return, so I don't know how to handle it on the php side either.

When a Dynamic Multiple line text field is used in Flash CS3, it has a very annoying feature that auto inserts a line break at the end of inserted text. It also auto inserts a line break if no text is entered too.
I'm having a problem with this because the text is being saved from flash to a text file on the desktop. With every multi-line text field there's a nasty looking line break.
Any way of "turning off" this auto-line-break-at-the-end feature?

I'm working on a project in which user data will be saved via php to an xml file on the sever. Using Kirupa's excellent tutorial [URL], I am able (now) to output to the xml file. My question is, does anyone know of a way to create the xml file so that the nodes will appear on seperate lines, as it would were I creating the XML file using Dreamweaver say.

If so, how do you handle line wrapping - so that the lines break at a particular word?

I have a problem with my ItemRenderer in Flex. I'm developping a mobile application and I'm using a list. One of the items is to set a date. But when the date is wrong I want to set a text in my messageField like : The To date must be after the From date.The problem is I don't know (and don't seem to find it anywhere) where you can set the messagefield in multiline.I read on a forum that's possible but no explanation how.Here you can see an example of what I want (the 5the item in the list is using multiline).[code]

I'm reading a 2d array from a .txt file, this is what I do:
Code:
[Embed(source = '../lib/lvl1front.txt', mimeType = "application/octet-stream")]
private var frontTxt:Class;
Then a bit further:
Code:
var fgString:String = new frontTxt();
foreGround = stringToArray(fgString);
The stringToArray function is where things go horribly bad:
Code:
private function stringToArray(input:String):Array
{
var output:Array = new Array();
[code]...
Notice the starting comma on every line except the first? I think it's the newline character somehow interfering, but I've tried everything I can think of, and nothing has helped.

I am sending a dynamic multi-line textField text to a database. Upon receiving it back, it doesn't display it in multi-line format properly. I am also using htmlText, so it stores it all the font / size /etc in the database perfectly.This code shows you the textField attibutes, both the text I create and send to MYSQL, and the text I get back also calls upon these exact attributes
Code:
TF.type = TextFieldType.INPUT;
TF.autoSize = TextFieldAutoSize.LEFT;
TF.useRichTextClipboard = true;[code]......
when I called upon the text from the database. It at least made it multi-line, but it messed it up a bunch also. My text is only 3 lines, but with wordWrap, it made it 8 and made it look off.Anyway, the text / font / color and everything comes in perfectly, except for the multi-line part.

I have two requirements for a flex charting component:
1) The grid lines should always remain fixed to a scaling I define using an array of data. Something like a graph paper sheet.
2) Plot multiple line series data over this grid.
How does one get complete control over the background grid lines? I have tried a combination of annotation elements and setting the linechart background elements. If I get the grid right, I can't plot over it (Probably due to the scale). how would one go about designing a graphpaper like interface for linecharts in flex/actionscript?

I am using text layout framework textflow in Flex 3 to get embedded images. In the edit field for the application the user can apply formatting. This all works fine except if the user deletes all the text they have entered and then starts typing again then the formatting is lost.[code]To setup the initial formatting then similar code to apply the formatting when the user changes it.So how can I stop the user from 'deleting' the formatting if they delete all the text?

Is it possible to define the scenes and the frames in XML in Flash CS4, so that we can parse it in actionscript 3.0 and define the interactivity. I want to define all the UI elements and the event associated with UI like List control or button in XML format (XUL??) and then use actionscript to build the application logic. Are there some good examples?

I've got an algorithm that takes more than several seconds to complete. I'm trying to implement it into a 60fps flash game i'm creating. I am wondering if there is some provision in ActionScript3 to interrupt a computation in order to update the frame and continue the computation afterwards. There probably isn't, so I'm assuming the best method would be to perform the computation for x milliseconds, measure what the frame rate is after, then adjust the time the computation will run for next frame if the frame rate is less than or greater than 60 fps. The drawback with this is that the game won't run at a steady 60fps...
Any other ideas on how to (optimally) perform a large computation in AS3 while maintaining the framerate? EDIT: For the curious (the calculation, perhaps I should have said algorithm): I'm creating a motion planning library for game AI objects (one use for motion planning). The algorithm is along the lines of a RRT (rapidly exploring random tree) that iterates thousands of times. Demo link:[URL] Click to motion plan. The circle can "thrust" at a fixed magnitude in any direction. Also - there is no linear velocity damping (i.e. friction).

I using FlashMX to read in a value from an ASP page into a dynamic text box. This works fine.
I then use a motion tween animation to tween into another image, and there I put another instance of the dynamic text box, with the same name, but the value doesn't populate the text box. It's as if it reads the variable into the text box, but if I do anything to the text box, it loses the variable and can't get it back.
Further, if I switch back to the first frame, the value won't populate either, I have to refresh the browser page to repopulate the variable (read the ASP page again.)
Is there a way to maintain this variable throughout the movie, so that I can re-use it?

I have recently purchased Pageflip 3.6 (http://pageflip.hu/) for a project at work and what I am planning on doing is implementing a guest book which i have created in flash.The guest book I created consists of a file upload (for images) a comment entry and a signature section (where the user has a choice between a bunch of fonts and writes there name) which are located on the left page of the flip book and then on the right page it displays the post (using XML).
Now the guest book on its own works like a charm, but when it is called into Pageflip the buttons for the upload/submit stop working and nothing happens.The way Pageflip pulls in the swf/png/jpg to fill its content is through an XML file.Pageflip does have hot spots and controls to switch pages directly within the book but I have disabled them so that you can only switch pages through the control bar, as I thought the hot spots were conflicting with the input for the guest book but it didn't do anything it still will not allow me to use the controls for the guest book.
I know this might be kind of confusing I hope i described my problem clearly enough and any help or input at all would be fantastic. I'm fairly green with actionscript but i'm the only one at my agency that knows how to use it so its tough on me to do these advanced things without anyone to bounce ideas off of

I'm having a conundrum. I am trying to duplicate the link effect: http:[url]....The thing about that is that I am trying to create this for an HTML site as link transitions for a client. My issue is that the swf has to maintain size on ALL browsers and sizes. I've tried setting the html object sizes to 100%, but the video is smaller. Is there something I'm doing wrong?

I am going to be utilizing a flash/jquery powered gallery on a webpage that is maintained and updated with an xml document. The xml data is used to add and sort images into a grid of small thumbnail images. i will customize this component so that when the user rolls over a thumbnail it will trigger jquery to replace a div using hide/show. My employer would like to try to create an adobe air desktop widget that will mirror the content of this gallery so that as entries are added to the site users can access the content automatically via the desktop. I was thinking there may be a way to utilize the same xml document to maintain the app as well as the gallery. As there is a fairly tight turn around on this project, i was wondering if anyone could confirm that adobe air apps can be maintained in this way, or how to approach this particular client request.

I have a canvas component called myCanvas and I instantiated it with
var myCanvasPage:myCanvas = new myCanvas;
this.addChild(myCanvasPage);
Then I want to essentially reload myCanvasPage later on. In effect I want to do this:
this.removeChild(myCanvasPage);
var myCanvasPage:myCanvas = new myCanvas;
this.addChild(myCanvasPage);
except instead of creating a new instance of myCanvas, I want to use the already created instance of myCanvas and essentially reload or re-create it but making sure that the instance name and references to it remain the same.

I pretty much got it working. The only problem I'm having is that it's only full screen based off of the width. I want the picture to maintain it's scale, so I need it to fill the height if necessary and cut the sides off of the picture. You can see what I mean by clicking [URl]. Resize the browser so it's a lot taller than it is wide and you'll see what I mean. I want it to fit both height and width no matter which is taller. I've played around with it all morning and nothing.
Code:
// pic_mc is the movieclip that I used to load my full-screen background image.
function bgResize() {
pic_mc._width = Stage.width;
pic_mc._yscale = pic_mc._xscale;
if (pic_mc.height >= _yscale) {
pic_mc._x = (Stage.width)/2;
pic_mc._y = (Stage.height)/2;

I'm trying to highlight the current 'page' / movieclip by showing the onrollover state in navigation display/button.So the colour remains the onrollover state (in this case blue) while the particular movie clip/'page' is displaying. Changing when the user rolls over another button.I have two issues:1. I understand I have to place the button within a movieclip and have been experimenting with button '02' in the attached example.fla - however now I have done this the original action contained within the movieclip instance myScreen_mc is no longer working.
