[flexcoders] Re: Number of lines in

[kramus0]

Yes I thought so as well, but this doesn't seems to work. Below you
can find my code example.

So what I see on the screen are the first two lines of text with the
following content:

This is the fist line of text. 
And this is the second line.

But the trace log (even after super.updateDisplayList) shows that
there are still five lines with the following content. 

textField.numLines:5
textField.getLineText(0):This is the first 
textField.getLineText(1):line of text. And 
textField.getLineText(2):this is the 
textField.getLineText(3):second line. 
textField.getLineText(4):Third line is this.

Hope this helps.

This my example application:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
xmlns:components="components.*" layout="absolute">
        <components:MyText text="This is the first line of text. And this is
the second line. Third line is this." width="157" height="40"/> 
</mx:Application>

Here is my example class (derived from Text):

package components
{
  import mx.controls.Text;

  public class MyText extends Text
  {
    public function MyText()
    {
      //TODO: implement function
      super();
    }
                
    override protected function
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
    {           
      super.updateDisplayList(unscaledWidth,unscaledHeight);

      trace('textField.numLines:' + textField.numLines);
                
      for (var i:uint = 0; i < textField.numLines; i++)
      {
        trace ('textField.getLineText('+ i.toString() + '):' +
textField.getLineText(i));
      }                 
    }   
  }
}
