TextField selection. Stopping default behavior

1

I have a dynamic TextField with code on it. Normally, if you select text and then hit the up key your selection would move up. I want to prevent this behavior, because I’m using the UP key to tighten the leading.

I would think that “e.stopPropagation();” but then I realized that the event is happening on the same place.

The only thing I could think of is to capture the selectionBeginIndex and the [URL=“http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/flash/text/TextField.html#selectionEndIndex”]selectionEndIndex and then after the KeyboardEvent call the [URL=“http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/flash/text/TextField.html#setSelection%28%29”]setSelection method.

Any thoughts?


kerningTextField.addEventListener(KeyboardEvent.KEY_DOWN, updateKerning)

function updateKerning(e:KeyboardEvent)
{
    
    if(e.shiftKey)
    {
        trace("keyboardEvent with shift pressed");
        var currentTextFormat:TextFormat
        switch(e.keyCode) //Up Key
        {
            case 38: //Up key
            currentTextFormat = kerningTextField.getTextFormat();
            trace(currentTextFormat.leading);
            currentTextFormat.leading =  Number(currentTextFormat.leading) - 1;
            kerningTextField.setTextFormat(currentTextFormat);
            e.stopPropagation();
            break;
            
            case 40:  //Down key
            currentTextFormat = kerningTextField.getTextFormat();
            trace(currentTextFormat.leading);
            currentTextFormat.leading =  Number(currentTextFormat.leading) + 1;
            kerningTextField.setTextFormat(currentTextFormat);
            e.stopPropagation();
            break;
        }
    }
}
