[flexcoders] Re: Flex 4: MouseOver not firing on a UIComponent Item Renderer
It doesn't seem that skinning is something that Adobe considered would need to be done in a skin class, for an item renderer. But, you can apply a skin class to them if desired. At each level: GroupBase, Group, DataRenderer, and finally ItemRenderer, you get additional functionality; and consequently, a little more overhead. For instance, if you used ItemRenderer instead of UIComponent, you could use the "hovered" state to control the visibility of the button. However, I think that you're going about it the most efficient way in creating AS item renderers instead of mxml; especially for ADG. -TH --- In flexcoders@yahoogroups.com, Nick Middleweek wrote: > > Thanks for the tip... > > If I bumped up to GroupBase, does that mean I can use Spark skinning as well > or is this not related? > > > > > > > On 6 September 2011 16:31, turbo_vb wrote: > > > ** > > > > > > You might try bumping up from UIComponent to GroupBase and set > > mouseEnabledWhereTransparent = true; > > > > -TH > > > > > > --- In flexcoders@yahoogroups.com, Alex Harui wrote: > > > > > > Something has to draw onto every pixel, otherwise the mouse hit passes > > through to underneath.

Re: [flexcoders] Re: Flex 4: MouseOver not firing on a UIComponent Item Renderer
Thanks for the tip... If I bumped up to GroupBase, does that mean I can use Spark skinning as well or is this not related?

Re: [flexcoders] Re: Flex 4: MouseOver not firing on a UIComponent Item Renderer
brilliant, this worked:
this.graphics.beginFill(0xFF, 0); // zero = alpha off.
Thanks!

You might try bumping up from UIComponent to GroupBase and set mouseEnabledWhereTransparent = true; -TH --- In flexcoders@yahoogroups.com, Alex Harui wrote: > > Something has to draw onto every pixel, otherwise the mouse hit passes > through to underneath.

Re: [flexcoders] Re: Flex 4: MouseOver not firing on a UIComponent Item Renderer
Something has to draw onto every pixel, otherwise the mouse hit passes through to underneath. You can set the alpha to 0 and it will still work. You can also set background=true and pick a backgroundColor on the TextField and not have to draw the fill.

OK, well I've settled with the white background for now...
