I'm going to be putting loaded images within the htmlText of a textfield.

getImageReference fails when Textfield is created at runtime (returns null)

how do i get it to work?

var Holder:Blank = new Blank;
 
//this works
//myText created at design time
myTxt.htmlText = "<html><img src='Blank' id='Blank1' />hello</html>";
Holder =Blank( myTxt.getImageReference("Blank1"))
Holder.addChild(new test) //any Symbol from library
 
 
 
//this fails
var txt:TextField =new TextField(); 
addChild(txt);
txt.width=500;
txt.height=300;
txt.border = true;
txt.htmlText = "<html><img src='Blank' id='Blank1' />hello</html>";
txt.multiline = true;
Holder =Blank( txt.getImageReference("Blank1"))
Holder.addChild(new test) //any Symbol from library
 
//Blank.as
 
package {
        import flash.display.Sprite;
 
        public class Blank extends Sprite {
                public function Blank() {
                }
        }
}

Open in new window

html-image.fla.txt
Blank.as.txt

hi, not sure if this would make a difference, but you're adding the child before you've specified the htmlText property.

Hello,

You just need to set 'wordWrap' to true before you can use the image tag at run-time. In the design-time created textField, wordWrap is set to true automatically be choosing a multiline textField type. At run-time you have to set it explicitly using the following code:

txt.wordWrap = true;

Also, set both 'wordWrap' and 'multiline' BEFORE setting the htmlText property.

I tested it and it works.

Hope this helps.

setting both 'wordWrap' and 'multiline' BEFORE setting the htmlText property worked.
