make UISprite widget always on top, no matter the atlas used

[Slyfox]

Hi, I would like to know if there is a way to make a UISprite always on top of any other widgets, even when multiple atlases are used.
 
I know about making the depth very high and z in the negative but if let's say one atlas is used in the background, then one in the front, then I wish to use the first atlas again in the very front for the cursor, then the cursor will be drawn as the same level as the background.

So even if it cost one extra draw call, I would like that cursor to be drawn separately in front of everything else.(basically as a special case)

Yeah, just use the Overlay shader that comes with NGUI.

thanks for the respond, though there seems to be more problem now since all icons are on top of the tooltip

Stick that sprite in a separate layer, add a UIPanel to the Layer Object and then raise the UIPanel object everything else, then it will definitely be on top of everything else, albeit, an extra draw call.

thanks Enay, it does work.
