It accually doesn't use any extra textfields, it stores the htmlText value of a textfield and gets the coordinates, it then resets the tf to the original value. I am thinking of making this a subroutine; assigning a textfield some value dynamically would be done through a special function that gathers spacial data before assigning the value.
Right now the the total operation is written in 300 lines of algorithmic code. I am frequently coming up with optimizations, so this number is droping... I will make it open source when it's finished because I finddevelopers and designers are often upset about not being able to measure rendered textfields. I figure this can be used for more than just text hover states. This will get you a rectangle of text, and it will also get you line metrics so I am thinking it will allow for some creative possibilities with typographic animation. It could be that a function defines the rectangle of all letters in a sequence for use with just words or short sentences. I suggest words and short sentences as any large body of text would cost too much in system resource with too many rectangles =] The dude at quasimondo.com tried mimicking the getLineMetrics function from Flex using bitmapData and getColorRect to measure the width of lines. It fails with custom anti aliasing, maybe even anti aliasing for animation. For some reason converting anti aliased text to bitmap data results in a blank bitmapData object... I wanted to run with his code but I found that it became far too elaborate as I was having to put the textfield in movieclips to get it to convert to bitmap data. This solution would fail too when image tags are used. It's a great theoretical solution but not a good practical solution. On 6/10/06, GregoryN <[EMAIL PROTECTED]> wrote:
Hello elibol, > Were your textfields multiline? No, they were just a row of links. What you're trying to do is really interesting :-). As I can guess, to work with non-monospace fonts, your getWordRect function should be quite smart... Also, the only way I can imagine so far (in about 15 min) must probably use a lot of duplicate textfields to get all these dimensions. What do you think, how often the need for hover event in html text arises? -- Best regards, GregoryN ================================ http://GOusable.com Flash components development.
