[flexcoders] please help itemrenderer accessing
Hi everyone, // *newbie alert*
I have a tilelist control in my main.mxml that has an itemrenderer
called thumbnail. within thumbnail.mxml there is a image control.
what I want to do is from actionscript in main.mxml is resize(using
a
slider) the image in the itemrenderer from main.mxml. if your
confused here is an clip from the files
main.mxml:
mx:Script
![CDATA[
private function sliderChange(event:SliderEvent):void
{
do the stuff.
}
]]
mx:HSlider change=sliderChange(event)/ ..
mx:TileList id=myHList itemRenderer=Thumbnail ..
thumbnail.mxml:
mx:Image id=thimage source={data.attribute('src')} ..
The dataprovder is xml using e4x. which is reading photos from xml
and
displaying them. that is working but I would like to resize the
thumbnails using a slider but all I can seem to do is resize the
tilelist control. which I don't think is right way to do it. even
if
nobody knows how to do this (which I'm sure is not the case from
what
I've seen on this forum) how do I get access to the itemrenderer
controls at all?
using actionscript 3 and flexbuilder 2
please and thank you for any help
RE: [flexcoders] please help itemrenderer accessing
ItemRenderers are tricky because they are recycled. Even resizing the
internal image might cause a re-renderer and change which renderer is
displaying the image.
I'd write my Renderers to pull from external data sources such as the
data in the dataprovider, or if you have to, some extrnal property that
is tweaked by the Slider. IOW, the slider could alter properties in the
same dp item that a renderer is watching, or the renderers could know to
look for an imageSize prop on the application.
