ActionScript 3.0 :: TextField Attribute For Height Of All Lines
Dec 15, 2009
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?
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 it possible to set the height of the sprite depending on the height of an textfield inside that sprite? I'm creating a box with a textfield inside it, but I want the box to be sized depending of how much text it is in the textfield..
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;
I'm trying to limit the number of lines people can enter in an input textfield. I tried stuff with maxScroll, but that doesn't check if people press enter, so i end up with too many lines of text. I then looked at maxChars, but it's no use either, because users can still enter as many lines as they want.Is there no way you can combine maxChars and maxScroll? there also is "textfield.onScroller" which checks if the textfield is being scrolled. Can't i use an eventhandler based on onScroller? Like:[code]this results in people not being able to edit messages anymore after they reach the end of the textfield.I have no idea how to limit the number of lines in an input textfield. Anyone?
There's only room for three lines of text in the interface, but the content is external and variable, and if it ends up taking up more than three lines, there needs to be some sort of 'view all' button functionality. I can kind of think about what that function needs to look like, but I'm not quite sure what the best way to do it in AS3 would be. Something like (in pseudo code):
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 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 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)
I try to get height of the textfield with htmlText='<img src="path/to/img.png" /><p>...Some text....</p>';To retrieve text height I use myField.textHeight property. But it always returns height of text without image.
How do I predict the TextField height? When I initiate one, it comes with 100 height, but I want to set it to the fonts height.
I have tried the autoSize, but some times it shrinks the text field to a very tiny one, and some times it stays at fonts height, but I can't set its width anymore...
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.
Using 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?
I'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.
I 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? (Unfortunately I can't provide a link or an image, since I haven't made 50 posts)
So 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?
I have: - a flash movie with 300x20px dimensions - a dynamic textfield - xml data parsed into the textfield 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):
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):
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]
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?
