I would override measure() and see what you're getting for the measuredHeight of the renderer. I'm guessing that it won't be right due to fact that flow-based text is "hard" to measure.
A custom measure() routine would probably be better. Renderers have their explicitWidth set when they are measured and you'll need to use that to fix the widths of the text widgets to get an accurate height. If it were me, I'd use a UIComponent with two TextFields and a custom measure() method. -Alex blogs.adobe.com/aharui ________________________________ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of jandersen1978 Sent: Saturday, September 08, 2007 9:44 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] variableRowHeight=true in List messing up height of last row I'm adding simple chat functionality to an application I'm working on and have the following List displaying messages: <mx:List width="100%" height="85%" id="lstMessages" itemRenderer="org.MessageRenderer" variableRowHeight="true" dataChange="handleDataChange(event)" dataProvider="{messages}"> </mx:List> here's the event handler: private function handleDataChange(e:FlexEvent):void{ lstMessages.scrollToIndex(lstMessages.rowCount -1); } the MessageRenderer is as follows: <mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml <http://www.adobe.com/2006/mxml> " width="100%"> <mx:Text text="{data.fromName}" width="20%" id="lblUser" color="{data.color}"/> <mx:Text text="{data.message}" id="lblMessage" width="80%" color="{data.color}"/> </mx:HBox> What I'm finding is that with variableRowHeight=true the last row in the List is always rendered with virtually no height such that none of the message text shows up. You can only see that it's there by mousing over it to see that it does display a few pixels of height (a border or padding perhaps?). When a new message is added, the previously squashed row displays normally and the new row is now vertically challenged. With variableRowHeight=false each row displays normally (except that text wrapping in the messsages doesn't work which is why I have it set to true in the first place...). I tried adding a call to lstMessages.invalidate() in handleDataChange but it had no effect. One other item of note--with only a single message in the list it seems to display OK. Any ideas?
