[flexcoders] Flex 1.5 TextArea height
Hello FlexCoders, I have TextArea on the stage, it has some size. After app initialized I'm populating TextArea with new data, scrollbar appears and it works good. But I need next functionality,I need TextAreaexpand it's height, so all text is visible without vertical scrollbar. It looks like an easy task, we just should extend TextArea and at some moment set height of TextArea to new value, But here I have questions: 1. At what moment I should change height? What event I should listen? 2. What value I should set to height?

Re: [flexcoders] Flex 1.5 TextArea height
Hello Stanislav, This question was asked at Flexcoders not only once. Basically, the correct question is: How to determine the content length in mx:Text? mx:TextArea component does not measure itself when the text content is changed dynamically. Manish had suggested to override measure method of mx:TextArea http://www.mail-archive.com/flexcoders@yahoogroups.com/msg13269.html When I look inside implementation of measure method inside mx:Text, it is much more advanced then his mx:TextArea counterpart. Can you post the code when mx:Text component does not work for you? -- Best regards, Andriymailto:[EMAIL PROTECTED] Yahoo!

Re[2]: [flexcoders] Flex 1.5 TextArea height
Hello Stanislav, One more idea found by me at history of the Flexcoders mailing list is to use TextFormat.getTextExtent() function to calculate the size of the text: http://livedocs.macromedia.com/flash/mx2004/main_7_2/1840.html#40 Example: -- var txtFmt:TextFormat=new TextFormat(); txtFmt.font=this.getStyle(fontFamily); var labelMetrics:Object=txtFmt.getTextExtent(code); var initObj:Object=new Object(); initObj.x=Math.floor(this.width/2)-Math.floor(labelMetrics.textFieldWidth/2); initObj.y=this.height-(this.getStyle(fontSize)+margin); initObj.text=code; this.createChild(mx.controls.Label,,initObj); -- -- Best regards, Andriymailto:[EMAIL PROTECTED] Yahoo!

ConcerningManish example, what is the magic numbers there? _measuredPreferredHeight = label.textHeight + 4; And it doesn't work! I will try getTextExtent workaround.

Ok, let's forget about getTextExtent.. Because it is has it's own limitations. What Adobe guys cansuggest to me?
