Flash MX - text fields...wrapping?

[tommypatros]

Is there any way to dynamically set the "character width" of a text field? I don't want the text to stretch - I want the text to wrap according to the width of the field, as text would in a text editor when you resize the window.

Any guesses?

Using a whole bunch of actionscript, you can do that now in Flash 5.
Have a look at this tutorial:

But maybe it'll be a little easier in flash MX.

There are much more functionality to textfields. You can create a WYSIWYG editor when I intepreted one Flashguru post lately right. (Can't find it right now, maybe on were-here)

If you do this:

//create a new textfield with wordwrap
//this.createTextField("instance_name",1depth,x,y,width,height)
this.createTextField("mytext",1,0,0,200,100)
mytext.wordWrap=true

Then if you put some text into the textfield:

i=10
while(--i){
    mytext.text+="another line of text\n";
}

Then if you change the width of text textfield using:

mytext._width=10

The text will wrap accordingly.

hi,guru

thx your coding,and i want add some talk:

textfield should has 16 width at least or it cannot work correctly.
and you can control its height-> mytext._height=number;

@guy or demons: Is there a way to check where the cursor and the selected areas (in the textfield) is? That would make a lot more possible.

Depends on the font, if you use the |(pipe) symbol and other such like, then the textfield can be two pixels wide if you want it to be.

ok,thx,guy.

Flash MX will make this much easier. Just a few more days... :-)
