I want to use an image as background of my window. But there is no

I know the menu item "send to back" in the "Layout" menu. But this
effects only the design time layout. When I do a "test run", my
controls are be drawn first so tha i can only see the image (NSImage).
To expand upon Ricky's great advice…
The AppKit does not support the layering of sibling views. The only
*guaranteed* way to overlap views is to formally implement a view
hierarchy and create subviews as necessary.
Some resources on this subject:
"For performance reasons, Cocoa does not enforce clipping among
sibling views or guarantee correct invalidation and drawing behavior
when sibling views overlap. If you want a view to be drawn in front
of another view, you should make the front view a subview (or
descendant) of the rear view."
<http://developer.apple.com/documentation/Cocoa/Conceptual/
CocoaViewsGuide/WorkingWithAViewHierarchy/chapter_4_section_5.html>
"Cocoa doesn't support overlapping views. If a view belongs "on top of"
another, then it should probably be a sub-view."
