Re: [flexcoders] Re: What comes after FlexEvent.INITIALIZE and FlexEvent.CREATION_COMPLETE?

[Michael Schmalle]

You know,I replied with the same exact post saying to migrate everything into createChildren();IMHO, you should never call callLater() on a protected method. There is just something seriously wrong with that path.
I don't know but, I tried it with the create children and set the width (to get it to wrap) and it works fine without the callLater()..???> They still end up on top of each other.You have top post the exact mxml you are using or this is like a dog chasing it's tail. :)

            It's not actually the events that are giving you a problem, but rather 
it's the tricky nature of dealing with auto-sizing text measurement.  
Add this statement to your measure function:

trace( "textHeight = " + textField.textHeight );
trace( "height = " + textField.height );

When the components are first added into your VBox, you'll see that 
their textHeight is actually 0 and the textField height is 4.  Now, when 
you roll over the checkboxes and measure is called again, you'll see 
those numbers change to be the "actual" values, and that's when they're 
drawn correctly.

Here's what I changed your code to to get something that works.  It's a 
bit of a hack in that it just calls measure again in the constructor 
after things have had time to measure, and I cleaned it up a bit to not 
rely on those events (you should override createChildren, as I've done 
below).  Note I've also re-named the class to describe its purpose better:

package
{
import mx.controls.CheckBox;
import flash.text.TextFieldAutoSize;

public class MultiLineCheckBox extends CheckBox
{
    public function MultiLineCheckBox()
    {
        super();
       
        callLater( measure );
    }
   
    override protected function createChildren():void
    {
        super.createChildren();
        textField.wordWrap = true;
        textField.autoSize = TextFieldAutoSize.LEFT;
        textField.border = true;
    }

override protected function measure():void
    {
        super.measure();
        // Make sure the text field has measured itself
        if ( textField.height > 4 )
        {
            measuredMinHeight = minHeight = textField.height;
        }
    }
}
}

I hope this helps!
