[Flashcoders] AS3 text fitting in variable box
I need to place project-titles in a multiline textfield, wherof the width will be fixed, but sometimes this box might be of less height because of more space used by other displaying project elements. Is there a class that can dynamically regulate the font it's size to fit the loaded text to a certian textfield height of a multile textfield? The project titles are variable in character word length. How is this solvable. Thanks !

Re: [Flashcoders] AS3 text fitting in variable box
Sounds like a bad design decision to make titles of the same category various sizes. But I think you can just set the .width property, then set the .scaleY equal to the .scaleX or visa versa depending on which dimension is more important.

Re: [Flashcoders] AS3 text fitting in variable box
I'm talking about font size, not stretching a container. Increasing / decreasing font size to get an optimal fill of a box which will have a fixed width and a certain height which can only be determined during load time. I could increase the font size of a textfield in a loop and measure it's height on every point increase; when it overflows my wanted box-height I take the font size of the previous step. Is there an easier way ? Stijn Joel Stransky wrote: Sounds like a bad design decision to make titles of the same category various sizes.

Re: [Flashcoders] AS3 text fitting in variable box
Is there an important distinction between scaling a TextField object and changing the font size? Perhaps you are storing the formatting or there are visual rendering implications or anything?? Otherwise, it seems like Joel's solution would work nicely to achieve what you want. -jonathan On Wed, Nov 12, 2008 at 6:18 PM, Latcho [EMAIL PROTECTED] wrote: I'm talking about font size, not stretching a container.

Hi Joel, Jonathan anf Dave for your answers Dave could you explain what you mean with a binary search ?

My only suggestion is a speed optimization: use a binary search instead of trying every font size.

No problem. A binary search is an order log(N) method for finding something in an ordered list of elements, as compared to linear search, which is order N. (N is the number of elements, in this case, font sizes you are willing to use.) You have a sequence of font sizes. For each size, it either makes the TextField too tall, or it doesn't. You want to find the biggest size which isn't too tall. The linear approach is to start from one end of the font size list or the other and try sizes one by one until the TextField height crosses the threshold. The binary approach is to try both ends first, say 1 and 50. If 1 is too big or 50 is too small, you already have your answer. If not, try the middle: 25. If 25 is too big, move your idea of biggest down to 25, and try the middle between 25 and 1: 13. Maybe 13 is too small, so change your idea of smallest to 13. Then try the middle between 13 and 25: 19, and so on. Once the two ends (smallest and biggest) are adjacent elements (say one point difference in font size), the one marked smallest is your answer. Binary search is only a little more complicated than a linear search to implement, and if you are searching over a large number of font sizes, the savings can be significant. If it's just 4 or 5 font sizes it's probably not worth the trouble. Binary search is a very classic computer science algorithm, so I'm sure you can find good descriptions on the web.

Re: [Flashcoders] AS3 text fitting in variable box
The distinction is that wordwrapping should be optimal, as you know when you increase / decrease a fontsize, the wordwrapping changes. jonathan howe wrote: Is there an important distinction between scaling a TextField object and changing the font size?
