dynamicly center text box

[Beyond Flash]

I need to keep a text box centered in the middle of the stage (horizontaly) no matter how wide the text box is (it will get bigger and smaller dynamically).


I also need:

How can I get a dynamic text box to always display the text at the bottom?
Similar to the "align bottom" with a cell in a table.


any help would be great.

The basic forumula for keeping something centered is:

thing._x = (Stage.width - thing._width)/2;

or, if you've precomputed the center coordinate, you can use:

centerCoordinate = Stage.width/2;
thing._x = centerCoordinate - thing._width/2;

If the text box is contained inside a movieclip, you can use the movieclip width. Otherwise, you can set the textfield to autosize and use the textWidth property instead of thing._width.

The basic forumula for keeping something bottom-aligned is:

thing._y = bottomCoordinate - thing._height;

Again, you can either contain the textfield in a movieclip, and use the movieclip height, or you can set the textfield to autosize and use the textHeight property.

How would I go about using the texthight property?

[jbum]

Let's say your textfield is called myText.

When you initialize it, you set autoSize to true:

myText.text = 'initial text';
myText.autoSize = true;


When you change it, the textHeight property will tell you how tall it is.

myText.text = 'changed text';
myText._y = 200 - myText.textHeight;
