Actionscript 3 :: Detect Number Of Lines Required By Piece Of Text?
Dec 21, 2011
This one is for all the TextField wizards out there. I have a text field that displays 2 paragraphs of texts. The first one I want to be truncated to show only 3 lines of text maximum. The 2nd paragraph is to be appended to that text.
Is there a way I can show only the first 3 lines of the first paragraph? Think of it like an abstract for an article for the first paragraph.
I tried doing it with String.subStr(0, guestimate of 3 lines of chars) but it's pretty inconsistent in that some strings will take up 4 lines of the textfield.
I thought about doing 2 separate textfields but in the case of the first paragraph having only 1 line worth of chars, there will be gap of 2 lines worth of chars between the 2nd paragraph.
I've been trying to detect the number of lines used in a dynamic textfield without any luck. I have tried using the scroll property of a field which didn't work (Find my attempt attached)
I'm loading a few bits of text into a dynamic textbox and I want to know if it's possible to find out the number of lines its taking up. Using the height of the textbox isn't an option as the text varies all the time.
I'm working with an input text field that has to contain a max number of characters (90... I set this on the properties panel) and a max number of lines: 6 but i don't know how to set this property.... I've searched, and all I could find was the numLines property, but it doesn't allow to specify the number of lines iI need my text to have...
I need to count the number of lines that exists in a txt file, from wich I load some content. I think I need to escape the content of the txt to be able to read the "/n", to count them and to have them displayed as variable (for example t_linenumber=...?)

I have a textfield that acts as a log in that it routinely gets messages added to it. I want to limit the number of lines the textfield can display - that is, if the textfield exceeds a certain amount of lines, the oldest lines that were added are removed and the rest of the lines of text are shifted up. Basically I'm wondering if there is a cleaner way to do this, as my technique seems inefficient:
Code: const MAX_LOG_LINES:int = 50; // assuming parameter message is a string that ends in to add a line break. function addText(message:String):void
I can't seem to figure out the .numLines property. I've tried calling it on a TextField that was created dynamically. The TextField has multiline set to true and wordWrap also set to true. Any clue why it would consistantly report the number 1? It's being called in a trace statement after the htmlText is set to a string from a xml file.
I want to implement paging in a spark text area. For that I want to find out the number of lines a spark textArea can hold before the scrollbars appear and just feed that much lines to the text area.
I would like to know is there any limitations in flash textarea like the number of lines it can have or the number of bytes it can have. iam opening a text file using php in textarea, where all the contents of the files are not getting loaded in the textarea. If it is there then how to increase its size, is it same thing in flex?
Here is the snippet of my code which is causing this error:[code]Description: Type mismatch in assignment statement: found Number where String is required.Source: for (a=0; a<cabinets[index].length; a++)Which is peculiar because when I alter it to: for (a="0"; a<cabinets[index].length; a++) { it throws no errors anymore however this is now incorrect because a is now a string.
I am looking to create a drawing component on a site. that should be straight forward.the issue lies with the fact that I would want to detect any collisions say (4) and then attach MC's to the collision points.in a nut shell.can I get a trace of the drawn path on the stage?????from there I guess I can detect any positional similarities?
Over the course of four nights in April and May of 1941, Belfast was attacked by the German Luftwaffe bombers. Their aim was to destroy strategic targets in the city which were aiding the British War Effort.What I want is for users to be able to select the word 'German Luftwaffe' and then they will be brought to another frame with information on that topic.
The stage width is 300px. I have the TextField for Question, wrapped set to true, so that if the Question is long it will continue to second line.Now the problem is i need to show options as radio buttons, say 10px below, where the question ends. But since i don't know the question consisted of two lines or one line, it becomes difficult for me to place the radio buttons programatically.How do i get the number of lines for a text field?
questionField = new TextField(); questionField.text = question; questionField.width =280;
All I want to do is create a flashing box to highlight an important piece of text on screen.How can I create a simple rectangle that will flash say between blue/ green for a few seconds stop flashing and box still be visible. Its literally just to highoight some text on screen I need to make sure everyone reads.
i have an image gallery, slightly modified from kirupa's xml image gallery, and for some reason the desc_txt text field isnt filling with the <piece> node from the xml file. everything else works. the text field is set to dynamic text and the instance name is correct (desc_txt). here is the actionscript,
I have an animation that reads some info from a txt file (such a bkg color, bkg image and text). So I would like to make my main animation in the root to repeate a segment of the animation (beteween 50 and 80 frame) or to loop an MC so many times like the number of lines in this txt file.
For exapmle if I have in my txt 6 lines to go from 50 to 80 frames, that again to 50 and like this 6 times (e.g. to repeat this segment 6 times)

I have an app that has text appended to a TextArea (TA). It automatically scrolls to keep the recent line added in view. Over time, this could be a lot. Do I have to worry about this? Is there an upper limit? And, if so, how can I prune the oldest lines of text?
I am trying to put together a match activity where word in one column are linked by a line to definitions in another column. Once all words have been linked to their definitions, you end up with a series of crossing lines so, so I want the definitions and their line to move so that each is level with their connected word and the lines have unravelled. I've got as far as connecting the words to their definitions using a line (as a sprite) and the definitions can then be moved using tweenlite -but I have no idea how I move the lines with their definition. Here is a much simplified section of code to give you an idea of what I am trying to do
I want to change the code a little bit by creating an Input Text. A random number will be typed in that text instead of having a fixed, pre-set number.
On my website, I display uploaded PDF files in a flash player for my users to read. I already use various tools to extract the text and produce a serious of high quality images from the file and the system works well. The last piece of the puzzle is to be able to highlight specific parts of the document to help users with accessibility issues.
However I cannot figure out how to calculate where the specific text is positioned on the page? Notes: The documents uploaded to the system are from 3rd parties, so fonts may be embedded. Meaning that I cannot be sure of the width of specific letters. The text to be highlighted may not be unique, the same text may be repeated How can I calculate the coordinates, height and width of a specific piece of text on a PDF, so that I can then draw a box around it?
I am working on an application in which i have put one Multi line input text box. I want to allow user to enter data only up to 8 Lines. User can not enter more than 8 lines. So is there any solutions..??? I dont want to use MaxChars as it can restrict user to not enter more than predefined number of characters. I want to restrict user from entering more than predefined number of lines.
