Re: [flexcoders] list itemrenderer
Yves, sorry for slow reply... I've written a custom itemrenderer for a list component, but the proxy instance (when dnd'ed) has to look different from the instance of itemrenderer which is actually dnd'ed. The proxy uses same class and receives same data object as item in list... so is there a possibility to set a property only for the proxy instance, or get a property to distinguish proxy from an instance actually in the list ? thomas --- http://www.web-attitude.fr/ msn : thomas.parqu...@web-attitude.fr softphone : sip:webattit...@ekiga.net téléphone portable : +33601 822 056 2009/5/25 Yves Riel > > > You'll have to be a little bit more specific.

RE: [flexcoders] List ItemRenderer and variableRowHeight
Unless you want the TextArea's scrollbars, you should just set
wordWrap=true and the default renderer will take care of it. If you
want to customize the renderer, copy the code and modify it. TextArea
is a bit heavy for renderers especially if you don't need the
scrollbars, and the default renderer code will show you how to figure
out the appropriate measuredHeight.

Subject: [flexcoders] List ItemRenderer and variableRowHeight
I have a List component with a custom item renderer. The List is set
to variableRowHeight=true.
In the renderer is a regular TextArea component that I want to grow in
size vertically for the longer data strings.
My problem is I don't quite understand how to automate the process of
sizing the TextArea and then the renderer height from the
TextArea.textHeight property.
I can successfully do it manually, attaching a click event to the
TextArea, that calls the following function in the renderer:
private function updateHeight(ev:MouseEvent):void {
ev.target.height = ev.target.textHeight + 5;
this.height = ev.target.y + ev.target.height + 25;
}
This perfectly sizes each item when I click on them.
The problem is I can't get it to function properly when I try to size
them from an event representing the item's creation. I have tried
sizing on the following events:
1) renderer creationComplete and added events
2) in the data setter override function for the renderer
No matter what I try to do, automated sizing produces incorrect
results. I am sure I just don't understand - not the first time!!!
Thanks for any help!!!

[flexcoders] List itemRenderer based on VBox error when verticalGap
I'm using the latest Flex 3 Beta SDK and I've just created an itemRenderer based on a VBox which I'm using in a List. Everything is fine until you scroll down and then back up to the top, if you do this the first item height will have shrunk and it will never resize. I tried overriding the measure() method but that didn't fix it, but I did notice that if I removed the verticalGap on the VBox that fixed the issue. I'm not sure if this is a known issue or not (haven't tried with Flex 2), but I could do with a workaround for when a verticalGap is applied (without adding extra containers) if anyone has any thoughts. -D

You could use ITEM_ROLL_OVER instead, or set alpha to 0.

I added handlers for "rollOver" and "rollOut" to try to make a "delete this item" button appear and disappear for each item as you roll over / out of it. The button was fizzling on and off until I set the background color and alpha of the HBox (to 0x0 and 1.0)... then the button appeared and disappeared as expected.

[flexcoders] List itemrenderer problem
Hi I m using a list with an item renderer(some labels). Items in the list shows some errors when i update an item in my dataprovider(array collection) . The item renderer's label donot shows the updated object's data.But the arraycollections is updated successfully..
Re: [flexcoders] List itemRenderer problem with example
Hi Tom, You're right that only a finite number of list itemRenderers are created. When something changes (like the visible portion of a list) those that don't need to be re-rendered are moved on stage. They are only re-rendered when the necessary (i.e. when the data changes). You have to make certain that each itemRenderer is properly initialized, and that if itemRenderers are moved, their state is checked and they are re-rendered accordingly. Posting the relevant code here might help expose the problem.

RE: [flexcoders] List itemRenderer problem with example
In your itemRenderer, you must update a property in the dataprovider item when the user causes the state to change, and in the overrides set data() function, you must read this item property and set the state accordingly.

I've found an example: Peter Ent's blog http://weblogs.macromedia.com/pent/archives/2006/04/a_list_itemrend.cfm When the dataProvider have less data (do not showing scrollbar when all items are expanded) all fine. But, it's not working with the big amount of data. When we scroll items the items expands automatically without any user actions. Can anybody say what the problem with it? Thanks for any advice.
