I have a textField with a lot of stuff in it, so I'm creating a scroller using a mask. To do the math to make the scroller work right, I need the height of the textField. But the stuff in it is retrieved from XML and the length of it varies when it is updated, which is quite often. Is there a way I can find the height of just the text in the textField?

I've created a dynamic text field, and set autoSize to true, so it can grow was tall as necessary. I then want to use the _height value to size a container graphic (speech bubble). Here's the (simplified) code:
[Code]....
Returns 19.6 followed immediately by 35.2. It's as though reading txt._height causes it to recalculate, so it's correct the second time. I also tried the textHeight property, which also seems to get recalculated after _height is accessed. This sequence, for example:

i would just like to ask why is the case that when i use embedfonts = true on a textfield, the textfield's text only resizes according to the textfield's height but not the textfield's width. meaning if i make the textfield's height bigger, the text also gets bigger in terms of height, but not width, can't the embedded font maintain aspect ratio according to the textfield height?
I'm only wondering about this because this is not the case when embedfonts= false
Is there a way to get the content of a component inside a scroller to be at 100% height.
here is a simple example:
<s:Scroller width="100%" height="100%">
<s:viewport>
<s:Group height="100%">
[Code]....
As you can see, the green bar (set at 100% height) is just using the height of the viewport, not that of it's parent group, that is stretched by the red one to be 500px high.
I am having a little difficulty properly sizing a Scroller component in Adobe Flex/Flash 4. As soon as I add an element to the 'widgetsGroup' VGroup, the scroller's height property resizes to match that of its parent border container, even though the content height of the vGroup may be significantly less than this value. This is a problem because the scroller then 'covers' other elements in the border container. I guess what I am looking for is the scroller height to match the widgetGroup content height until this height exceeds the bordercontainer height, at which point the scroll bar would become visible.

The movie clip is a scroller which I download a while back (I can't remember where from now) The contents of the scroller which i want to scroll is a seperate movie clip which loads it's contents from a .txt file. The problems I am having are:
1 - I cannot seem to change the height of the text box movie, I can change it in flash, but when i publish and play it just appears at a set size.
2 - the last link in the contents jumps like crazy when I hoover over it.
3 - when there is less content than the size of the text box I would like the scroller to disapear.
4 - If I add a mask around the text box, the contents disapear, i have in place a custom mask for the mean time but this will have to go.

I am trying to make a flash blog and basically I need to be able to load in text from an xml file into the different text fields I have setup and then I need to read the height of the loaded text so I can position the next post correctly below it.
Code:
blog_xml = new XML();
blog_xml.ignoreWhite = true;
blog_xml.onLoad = function(success) {
[Code].....
This code returns the height of the text field BEFORE the xml text is added, how to make this script wait until after it is added.
I have an automatically generated TextField, that is fixed in its width. To show it in its full heights and not to have the scrollmode active I want to read out an attribute that contains the value of the summed up height of the single lines. Then I want to set the TextField.height to this value, to see the full text at once. Does such an attribute exist in the TextField-Class or do I habe to sum up the height of the single lines by multiplying TextField.numLines * TextField.getLineMetrics().height?
View 1 RepliesUsing the flash authoring tool, I want to resize a dynamic textfield to a particular height.However, it will not allow me to size the textfield smaller than a height that will fit all of the (multiline) text. How can I override this and make the height smaller so I can use scrollbars?
View 5 RepliesI'm attempting to load HTML from the Shopify blog API into a TextField in Flash. The problem is that Shopify doesn't add width and height attributes to images that are in the blog posts. When I load these into Flash, the width and height of the image is ignored and the height of the TextField is incorrectl, which screws up my scrollbar among other things.
Is there any way to read the width and height of the images as they are loaded? I could possibly do this with PHP before it gets to Flash, but I'm not sure how.
I have just come up with this idea of passing in strings into a textbox. The problem is having the height automatically adjust depending on how long the string is. So I have set width for my textbox, but I want the height to change if the string is long enough to wrap.
View 2 RepliesI want to change the height of a textfield to 60 pixels, without changing the size of the text, and still keeping it centered. When I want to change the size of the texfield, I can change the length, but the height is unfortunately locked. Any ideas?

View 1 RepliesSo I need the text to scroll with the text field object rather than inside the dynamic text field box. To do so I need the textfield box to auto fill a height based on how many lines it has, is there any way to do this or should I draw a static text field instead?
View 3 RepliesI have:
- a flash movie with 300x20px dimensions

Now I'm trying to scale the height of the movie/stage to the height of the textfield after the xmldata was parsed in. I've tried
stage._height = textField._height.
I am loading xml and using Colin Moock's scrollbar as he desrcibes it in Essential Actionscript 3.0. It all worked fine until I tried to put a link to a jpg inside the xml.Where other html tags give no problem, the img seems to mess with the textfield height. I gave the textfield a fixed height but when I try to scroll the field with the image, and trace the textfield height, it increases more and more when I scroll down, messing up the scrollbar.the img tag looks like this (and it loads fine into the textfield):
Code:
<IMG ALIGN= "left" SRC='pics/portret.jpg' WIDTH="200" HEIGHT="207" HSPACE='0' VSPACE='10' />
The slightly adapted scrollbar class looks like this (I gave the scrolltrack a fixed height and tried to give t.height a fixed height too within this class but tracing t.height keeps showing that it is increasing while scrolling down):
Code:
package {
import flash.display.*;
import flash.text.*;[code]..............
So I think that the code or flash doesn't handle the img very well,
I am building a dynamic multi-line textfield that has a backdrop so I need to know about the height of the TextField. Strangely TextField.height will almost always return the right results. But sometimes (e.g. when the last line only has one word) it will return a wrong value with the last line missing. Am I doing something wrong? Or is this known to happen. And is there a good workaround? Should I use getBounds instead?[code]
View 1 RepliesI'm trying to change the height of a wordwrap textfield. When I change the width property everything seems to work properly (the height is increased if width is small). But when I try to change height, nothing happens (I would think that the width will increase if height is too small). Here's the code
Code
var tf:TextFormat = new TextFormat();
tf.font = "Verdana";

I have a TextField with multiline and word wrap enabled, and a fixed width. I want to calculate the total height of the text inside it. I tried using TextField.textHeight, but that gives me the height of one line. Because of the wrapping, I can't easily calculate the number of lines to multiply it with the line height. TextField.height just gives me the fixed, default height of the field, 100 pixels.
View 2 RepliesI have a Flash file, which has to be liquid. I have a header, a footer and a center section, which all are percentage scalable. My center section has a MovieClip called info_txt, and I'm trying to make it high 20% of the center_mc's height. I do this, but I also load a text in that field (info_txt) with XML, and when the text (xml) is loaded and placed in the textfield it doesn't go multiline, but stays nowrap.
View 1 RepliesIn a card game I use a TextField in the middle to display the playing table number, but also to detect if a playing card has been played - using myTextField.hitTestObject(myCard) - which means the TextField's position and dimensions may not change:
My current AS3 code is:
var format:TextFormat = new TextFormat();
format.color = 0xFFFFFF;
format.size = 30;
[Code]......
However the TextField's content (the String "#2029" in the above screenshot) is not in the center of it.
I can not set _middle.autoSize = TextFieldAutoSize.CENTER because this changes the width of the border (and breaks hitTestObject()).
Is there another way to align the text in the middle?
i have this problem with my text field. i have this dynamic text field, and i want to load external text files and show them there. this all works fine and dandy but when i try to make a scrollbar along with it, it gives the height of the text field as the original one from the flash file, not the new text.

View 2 RepliesI have text that loads into a dynamic text field that is on the stage. The movie clip("tile" in code below) in which the dynamic text field resides is placed on the stage via loop function.I can load the text from the xml file just fine.However, since each text field in loop autosizes, which is what I want, (in height only-width is fixed), I want the next text in the loop to load in a Y position based on the previous text box height including a "cushion" of my choosing. I'm very close, but can't seem to get the math right that is needed for the tiles Y position...
