updateDisplayList() is called during the next 'render' event that occurs after invalidateDisplayList() is called. > I always call super.updateDisplayList() when ever I override it. This is generally a good idea. > Now once I removed super.updateDisplayList() from the my itemrenderer and still it was working . This may have been because UIComponent's implementation of updateDisplayList() doesn't currently do anything. But it might in some future release, so it's a good idea to call the supermethod. > if i want to change property of some component like color do i want to call invalidateDisplayList()? You should call invalidateDisplayList() from a property setter if changing the property should cause the component to redraw or re-layout its children. However, colors are usually implemented using styles, not properties. - Gordon ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of arpan srivastava Sent: Friday, February 02, 2007 7:40 AM To: Flex Coders Subject: [flexcoders] how and when is updateDisplayList called ? Hi all, Can anyone tell how and when is updateDisplayList called ? I always call super.updateDisplayList() when ever I override it. I created a datagrid which contains line graph in one of it's columns. Now once I removed super.updateDisplayList() from the my itemrenderer and still it was working . Also if i want to change property of some component like color do i want to call invalidateDisplayList()? Thanks, ________________________________ Don't get soaked.
