ActionScript 3.0 :: Limiting Number Of Lines Of Text In Log Style Textfield?
Mar 28, 2009
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

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;

Is there a way to restrict the number of characters in the Flex Rich Text Editor? I guess there should be, since it's possible in a textarea. So, if I could get hold of the textarea contained in the rich text editor, I would be able to do it

Is there a max number of lines that can be displayed in a textfield?

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=...?)

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 have an input text field, it's grey and italic - it says "Enter album name here". When it's clicked I want the text to go away, and change the style to black/unitalicized so the user can enter some text. Here is my event function that triggers on mouse up. The text format changes properly if I set the text to "hi", but *not* if I set the text to the empty string... Is this a bug? My experiences with Flash thus far have been far from impressive for such an expensive piece of software. Maybe I am overlooking something...

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 display a uncommon layout into a HTML Textfield, using AS3/Flash CS4. This is what I need to create, is it possible? [URL]... I have tried some CSS styles, but I didn't found any way to align a span to the left. TLF is out of my range, the related project is closed to CS4, but if it is the only way, someone tell me!

I have some HTML loaded from an XML document that includes web links (anchor tags). I am using a TextField object to display the text, and am plugging the XML data into the htmlText property of the TextField, and the text is rendering with HTML markup, links are working etc.
The problem I'm seeing is that a new line is created before and after the link, so html like this:
hello world <a href ="#">this is a link</a> and all of this should be on the same line.
is rendered like this (with specific attention paid to the new lines): Does anyone know of a way to prevent these new lines from appearing when using HTML links within a TextField?

Is there a way to hide partially shown text lines on a dynamic textfield that has more text than its size can hold? I want to avoid the situation found on the picture below by simply not showing the areas in red (the text comes from lots of sources, so I don't have control over it).

it is possible to change text styles of single words or lines within a textfield with actionscript. I use an empty textfield and add my text to that field in actionscript with the following code:
myTfield.text = "insert text here"
the text contains multiple lines and I want some of them to be bold, italic or a bigger font size. The reason why I am adding my text to my textfield this way is because I need the text in the textfield to change when some buttons are pressed. Text will be added or removed from the textfield if buttons are pressed by the user and the current way I'm changing the text is by simply re-using the code above with new text in it. (it makes the code quite long though, but I guess I'll have to deal with that)But because I'm adding text this way I am not sure how to change the style of different parts of the text.
On a related note, with CS5 there are now a number of options for textfields. There is TLF text and classic text. I've searched around for the differences but I don't find the awnsers very clear. What option should I use for my textfield if I want it to look sharp like the text I'm typing here (its just regular text, no headers or anything). Some options just give blurry text because of the anti-alias and some settings don't seem to change a thing. And at times embedding fonts looks nice but sometimes it makes it worse. There are so many options to choose from, but it is unclear what would work best for regular text. (my text won't animate, it does move with a scrollbar, but I only care about how it looks when the scrollbar is still)

Is there any way? I thought "maxChars" was promising until I learned it was only for inputting text to a textfield.The XML is coming into a dynamic text box. I need to cut it off at say 500 characters and add an ellipsis.

At one point in my script I'd like to check a MC for the number of children and limit this number to 3. For that I use this script:
Code:
if (container.numChildren > 3){
for (i = container.numChildren; i > 3; i--){
container.removeChild(container.getChildAt(i-1));
popError('Horizontal nur 3 Elemente!');
}
}
This somehow works fine if there are 4 or 5 children in the MovieClip, but as soon as there are 6 or more, it throws an Argument Error #2025 and does not remove anything. BTW it does not make difference if I use container.removeChildAt(i-1);

Ok, I am new to Flash and I am using CS3. I just learned about creating lines and choosing their end cap styles and joint style. I created 2 lines that were connected, highlighted both with the selection tool and tried to change the join style to miter. It would not work. I also tried round and bevel but they would not work either. I did this over and over with many different sets of lines, and I could not change the join style. What am I doing wrong?

I already know how to limit my input text to a number of characters, but how would I go about (if possible) making sure characters do not repeat? In other words, I have a ten character input text box and I want you to be able to type pretty much any character but only one of each.
Example:
AFKEIOPCNK
What I'm trying to eliminate is this:
AANHDKDDJI
If that isn't possible, I'd like to instead detect if there are repeated characters so I can just say "that's invalid".

I have 3 clips on my stage each containing a textfield into which I load 3 html files. I seem to have this part working fine, however the css I have loaded is not being applied to any text field. Not sure why. I am sure the fonts are embedded correct also. I have attached all the relevant files if needed. Ignore the scrollbars. They are the next challenge.
ActionScript Code:
//load the style sheet
var cssLoader:URLLoader = new URLLoader();
cssLoader.load(new URLRequest("files/mici.css"));
cssLoader.addEventListener(Event.COMPLETE, cssLoaded);
cssLoader.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);
