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!
