The script is pretty much the stock script that macrodobe supply, with the exception that I added the autoSize=true property to the textField that is created.
One point I did notice is that this Cellrender extends UIComponent, where as the cellrenderer that Alessandro Crugnola uses here: http://www.sephiroth.it/tutorials/flashPHP/custom_tree/page002.php extends mx.controls.treeclasses.TreeRow - is there a reason why he does this? Here it is anyway: [AS] class MultiLineCell extends mx.core.UIComponent { private var multiLineLabel; // The label to be used for text. private var owner; // The row that contains this cell. private var listOwner; // The List/grid/tree that contains this cell. private static var PREFERRED_HEIGHT_OFFSET = 4; private static var PREFERRED_WIDTH = 100; private var startDepth:Number = 1; public function MultiLineCell() { } public function createChildren():Void { // The createLabel method is a useful method of UIObject and a handy way to make labels in components. var c = multiLineLabel = this.createLabel("multiLineLabel", startDepth); // Links the style of the label to the style of the grid c.styleName = listOwner; c.selectable = false; c.tabEnabled = false; c.background = false; c.border = false; c.multiline = true; c.wordWrap = true; c.autoSize = true; } public function size():Void { var c = multiLineLabel; c.setSize(__width, __height); } // Provides the preferred height of the cell. Inherited method. public function getPreferredHeight():Number { return owner.__height;// - PREFERRED_HEIGHT_OFFSET; } // Called by the owner to set the value in the cell. Inherited method. public function setValue(suggestedValue:String, item:Object, selected:Boolean):Void { if (item==undefined){ multiLineLabel.text._visible = false; } multiLineLabel.text = suggestedValue; } } [/AS] Darren -----Original Message----- From: Mark Mulhollam [mailto:[EMAIL PROTECTED] Sent: Wednesday, 23 August 2006 3:30 PM To: Flashcoders mailing list Subject: RE: [Flashcoders] Multiline text in a Tree Component You should post your cellRenderer script.

I am using the basic multiline code framework from Macrodobe here: ttp://www.adobe.com/support/documentation/en/flash/fl8/samples.html <http://www.adobe.com/support/documentation/en/flash/fl8/samples.html> If I set the textfield autoSize property in the cell, 90% of all text fields will auto-size and auto-centre vertically properly. But for some strange reason, there are a bunch that dont centre. They are usually off by about 5px. Some you can actually see drop when the cell re-renders. I am sure it is something to do with the textfields reporting an incorrect height size after the text is applied to the textfield, but i am having a nightmare figuring out how to code around it. Here is an example of what happens: http://www.3ddu.org/test/treeViewComponent.html <http://www.3ddu.org/test/treeViewComponent.html> Has anyone got an elegant solution to a multiline cellrenderer that centers vertically or a hint on where to look to solve this?
