I very much doubt that the Player team will remove this API, although I can't promise that. In any case, TextField is not going to get much attention in the future. It will continue to be supported for backward compatibility, but the new flash.text.engine APIs in FP10 are the foundation for text display from now on.

Hi Gordon, I've found the submission patch at Adobe JIRA bug-base you've been referring in a previous message: http://bugs.adobe.com/jira/browse/SDK-16641 While I fully welcome this fix, it does not suit my needs precisely. I've studied source code of <mx:Text> private function "measureUsingWidth(widthValue)" and that was closer to solve my task. I've reused this method in my custom Text component to take into account the values of "blockIndent" values specified to all TextFormat applied to the textField under the question while measuring the width for this component in override protected "measure" method. To return the Array of all TextFormats applied to the textField I rely on undocumented Flash Player API - flash.text.TextRun http://nondocs.blogspot.com/2007/05/flashtexttextrun.html - is it OK to rely on undocumented Flash Player API in our projects? Then, I calculate the maximum BLOCKINDENT value within all TextFormats objects found for the textField and then I make sure in my "|measure" method for my Text component to take this maximum BLOCKINDENT value into the consideration, e.g measuredWidth = Math.max(MIN_TEXT_HEIGHT, Math.ceil(textField.textWidth) + UITextField.TEXT_WIDTH_PADDING + maxParagraphIndentValue); 2008/11/4 Gordon Smith <[EMAIL PROTECTED]<mailto:gosmith%40adobe.com>>: > It sounds like a Player quirk that the Flex framework needs to work around. > I think a fix went in to the measure() method of UITextFormat recently for a > similar problem with 'indent'.
